Buy Citric Acid for Food, Pharmaceutical and Chemical Industries; Select the Citric Acid Grade Based on Application

In buying citric acidfor industrial use, the most important decision is not simply finding a white crystalline material called Citric Acid. The buyer must precisely define the product form, grade, standard, and application. A beverage factory focuses on flavor consistency, rapid dissolution, solution clarity, and food documentation. A pharmaceutical unit may require USP, Ph. Eur., GMP, DMF, or elemental-impurity control. A detergent factory focuses more on acidity, chelating power, moisture, and behavior in the formulation.

For tonnage orders,citric acid price must be considered alongside the actual cost of use. A cheaper product with higher moisture, unsuitable granulation, or batch variation can disrupt mixing, packaging, dosing, or the appearance of the final product. In continuous-process factories, supply consistency and analytical consistency can sometimes matter more than a few percent difference in price.

Buy Anhydrous Citric Acid for Low-Moisture Formulations

Anhydrous citric acid contains no water of crystallization and is a common choice for instant powders, dry mixes, effervescent tablets, certain supplements, and formulations where additional water is undesirable. Jungbunzlauer also identifies the Anhydrous form as suitable for Dry Blend applications.

Buy Citric Acid Monohydrate for General Applications and Solution Preparation

Citric acid monohydrate contains one molecule of water of crystallization. This form is used in many food, beverage, detergent, and industrial applications. The difference in molecular weight and water of crystallization must be considered in precise dosage calculations and when comparing the prices of the two forms.

Buy Food-Grade Citric Acid E330 for the Food Industry

For food grade, simply having the word food on the bag is not sufficient. The COA, reference standard such as FCC, E330 status, country of manufacture, batch number, contaminants, and food-contact conditions must be reviewed. The documents must belong to the same manufacturer and the same grade.

Buy Pharmaceutical-Grade Citric Acid USP and Ph. Eur.

In pharmaceuticals, compliance with the official monograph and control of manufacturer changes are more important. For certain applications, GMP, CEP, or DMF documentation may also be relevant. Food grade should not be used as a substitute for pharmaceutical grade without documented evaluation.

What Is Citric Acid? Citric Acid Specifications, Lemon Salt and E330

Citric acid is a tricarboxylic organic acid with the formula C6H8O7. Its anhydrous form is identified by CAS number 77-92-9. The monohydrate form has the formula C6H8O7.H2O and CAS number 5949-29-1. In the food market, E330 is used as the identifier for citric acid.

In Iran's retail market, the term lemon salt is sometimes used for citric acid, but in industrial purchasing this name is best used only as a search synonym. The contract should state the exact chemical name, form, grade, standard, and brand so that it is not confused with similar materials or food mixtures.

What Is Citric Acid E330 in the Food Industry?

E330 is the European food-additive identifier for citric acid. It is used to regulate acidity, create a sour taste, provide buffering, and chelate metal ions. The dosage depends on the formulation, product type, target pH, and regulations for the food category.

What Is the Difference Between Lemon Salt and Citric Acid?

In the general market, lemon salt usually refers to food-grade citric acid. In the industrial market, this term is not precise. The buyer should ask the seller to state the CAS number, Anhydrous or Monohydrate form, purity, and standard on the sales documents.

Is Citric Acid Natural or Industrial?

Citric acid occurs naturally in fruits, but modern industrial production is mainly based on fermentation of a carbohydrate source. After fermentation, the industrial product is separated, purified, crystallized, and dried to reach the required purity.

PubChem records the formula of citric acid as C6H8O7 and the molar mass of the anhydrous form as approximately 192.12 g/mol, and identifies it as a tricarboxylic acid.

Citric Acid, PubChem

Physical and Chemical Properties of Anhydrous and Monohydrate Citric Acid

Citric acid typically appears as colorless crystals or a white crystalline powder and is nearly odorless. Both anhydrous and monohydrate forms are highly soluble in water. High acidity, good solubility, and the ability to complex metal ions explain its use in food, detergent, pharmaceutical, and metalworking industries.

The Anhydrous form has no water of crystallization, whereas Monohydrate contains one water molecule in the crystal lattice. This difference affects molar mass, storage behavior, and calculation of the active-material amount. For dry formulations that are sensitive to moisture, the anhydrous form is usually the simpler choice.

Citric Acid Solubility in Water and Its Importance in Production

Rapid dissolution is important in beverage, syrup, detergent-solution, and industrial-bath production. Very cold water, high concentration, weak agitation, or insoluble material can increase dissolution time. Granulation also changes the dissolution rate.

Citric Acid pH and Solution Behavior

Jungbunzlauer reports a pH of about 1.8 for a 5% citric acid solution. The actual pH of the final formulation depends on concentration, water, buffers, and other ingredients. Citric acid has three acidic protons, and its buffering behavior can be adjusted with citrate salts.

Citric Acid Chelation and Metal Ions

Citrate can form complexes with metal ions. This property is used to control the effects of iron and copper in foods, as well as in descaling, detergents, metal cleaning, and aqueous processes. The strength of the effect depends on pH, the metal ion, temperature, and molar ratio.

Fine Granular and Granular Citric Acid Particle Size

Particle size is not merely a matter of product appearance. Fine powder dissolves faster but generates more dust. Coarser granules provide better flowability for volumetric dosing and packaging. In tonnage purchasing, the PSD or at least the granulation designation should be specified on the TDS or in the contract.

Differences in Citric Acid Granulation in Factory Dosing

In automated feeding, consistent flowability becomes more important than dissolution speed. A sudden change between Fine and Granular from one batch to another can alter bulk density and feed rate even when the Assay is the same.

Technical Specifications Table for Anhydrous Citric Acid and Citric Acid Monohydrate

The following specifications are provided for an initial comparison of the anhydrous and monohydrate forms. Contractual values must be taken from the COA and the standard for the grade being traded. Using a general table instead of the batch analysis sheet is a common purchasing error.

The anhydrous form is commonly identified by CAS 77-92-9 and a molar mass of approximately 192.12 to 192.13. The monohydrate form has CAS 5949-29-1 and a molar mass of approximately 210.14. Both are white, crystalline, and highly soluble in water, but they differ in water of crystallization and moisture behavior.

In industrial purchasing, appearance and pH alone are not sufficient for quality approval. Purity, water, sulfated ash, oxalate, sulfate, metals, and solution clarity must be checked against the target standard or the factory's internal Spec.

Citric Acid COA Analysis; Purity, Moisture, Oxalate and Heavy Metals

The citric acid COA must include the batch number and production date and must correspond to the same shipment being delivered. A general catalog shows only the target range. For tonnage orders, matching the batch number on the bag, pallet, and COA prevents discrepancies between the sample and the main shipment.

In technical sources from Cargill and TTCA, Citric Acid Anhydrous purity is listed at approximately 99.5 to 100.5% for many food and pharmaceutical grades. Limits for water, ash, oxalate, sulfate, lead, and other impurities vary by standard and grade.

What Is Citric Acid Assay in a COA?

Assay is the measurable amount of citric acid in the sample. A high value has limited meaning without the test method. The method should be aligned with the FCC, USP, Ph. Eur. monograph or the contractual Spec.

Citric Acid Assay Acceptance Limit for Food Orders

The acceptance range must be written precisely in the purchase Spec. If the factory purchases according to FCC, the COA result should be compared with the same monograph and test method, and the seller's internal tolerance must not replace the contractual limit.

Moisture or Water in a Citric Acid COA

For the anhydrous form, lower water is expected than for Monohydrate. Cargill states a 0.5% water limit for Anhydrous in one TDS. TTCA specifies tighter limits in some of its Specs. The purchasing value must be taken from the current COA.

Difference Between Water and Loss on Drying for Citric Acid

Water and Loss on Drying are not always the same laboratory concept. The buyer should read the method stated in the monograph or COA and compare the results of two suppliers only when the test methods are equivalent.

Oxalate and Sulfate in a Citric Acid COA

Oxalate and sulfate are indicators of purity and process control. The acceptable amount depends on the reference standard. In sensitive pharmaceutical or food applications, the buyer should not look only at Assay.

Heavy Metals, Lead and Arsenic in Citric Acid

For food and pharmaceutical industries, limits on metals and toxic elements are directly important. The test method and acceptance limit must align with the destination standard. In exports, differences in destination-market regulations must also be reviewed.

The table below is an example of common COA parameters. Exact values must be taken from the COA for the grade being purchased.

Cargill lists an Assay range of 99.5 to 100.5% for Citric Acid Anhydrous in its technical sheet, along with parameters such as water, ash, oxalate, arsenic, and lead.

Cargill Citric Acid Anhydrous Technical Data Sheet

Types of Citric Acid; Anhydrous, Monohydrate, Food Grade and Pharmaceutical Grade

Citric acid classification has two dimensions. The first is crystalline form: Anhydrous or Monohydrate. The second is the level of requirements: food, pharmaceutical, laboratory, or industrial. These two dimensions should not be confused. An Anhydrous product can be food, pharmaceutical, or laboratory grade.

For correct purchasing, the application is determined first, then the standard and form are selected. If the factory uses Dry Blend, Anhydrous is more logical. If a liquid food product is produced, either form may be suitable, and active-material cost and availability become decisive.

Anhydrous Citric Acid for Powders and Tablets

The anhydrous form is a common choice for dry mixes, effervescent tablets, beverage powders, and moisture-sensitive formulations. Differences among Fine, Fine Granular, and Granular particle sizes affect flowability and dissolution speed.

Citric Acid Monohydrate for General Applications

The monohydrate form contains one molecule of water of crystallization and is used in solution preparation, food industries, detergents, and industrial formulations. When replacing it with Anhydrous, calculations should be adjusted on a pure-material basis.

Water of Crystallization in Citric Acid Monohydrate in Formulation Calculations

For a formulation with an exact molar ratio or exact amount of pure acid, the mass of Monohydrate added is not equal to the mass of Anhydrous. The formulation unit must perform the conversion based on molar mass rather than a one-to-one kilogram substitution.

Food-Grade Citric Acid E330 and FCC

Food grade must comply with the destination-market regulations and the standard requested by the buyer. FCC is a common reference for food ingredients. In the United States, the FDA lists citric acid in GRAS regulations and food applications.

Food-Grade Citric Acid Documents for Supplier Approval

COA, TDS, Halal or Kosher status where required, the manufacturer's food-safety system, and certificate of origin are common documents. A factory should request only the documents required for its market and final product.

Pharmaceutical-Grade Citric Acid USP, BP and Ph. Eur.

Pharmaceutical grade must comply with the stated monograph. Jungbunzlauer refers to compliance with Ph. Eur., USP, and FCC for Anhydrous and Monohydrate. In sensitive API or Excipient applications, additional documentation beyond the COA may also be required.

Citric Acid Production Method; Fermentation, Purification, Crystallization and Drying

Industrial citric acid production today is mainly based on fermentation of a carbohydrate source. The feedstock may come from sugars or starch streams. The microorganism, fermentation conditions, and final purification determine product yield and quality.

Aspergillus niger is one of the well-known microorganisms used in industrial production. After fermentation, the biomass is separated and the citrate-containing solution enters purification, recovery, concentration, and crystallization stages. The exact process route can differ from one factory to another.

Citric Acid Fermentation Using a Carbohydrate Source

Control of sugar, pH, oxygen, temperature, and metallic elements affects metabolism and acid production. Microbial contamination or an unsuitable feed composition can reduce yield and quality.

Separation and Purification of Citric Acid After Fermentation

After fermentation is complete, cells and solids are removed. Color, protein, metal ions, and process impurities must be removed from the solution so that it is suitable for crystallization. Purification stages and the use of resin or activated carbon vary according to factory technology.

Crystallization of Anhydrous Citric Acid and Citric Acid Monohydrate

Crystallization conditions determine whether the product is recovered as Monohydrate or Anhydrous. Temperature, concentration, and water activity are important. After crystallization, centrifugation, washing, and drying are carried out.

Citric Acid Granulation and Packaging After Production

After screening, the dried product is divided into different granulation grades. Removing very fine particles is important for reducing dust and selecting particles with suitable flowability. Packaging is performed immediately after laboratory approval.

Citric Acid Producers and Reputable Brands for Buying Citric Acid in Iran

A significant portion of industrial and food-grade citric acid in the Iranian market is supplied by foreign brands. Therefore, the phrase citric acid producer in Iran must be used carefully. Some companies are actual producers, some are importers or brand representatives, and some are only distributors. The buyer should determine each company's role before signing a contract.

The names TTCA, Ensign, and Lemon Star are widely seen in the Iranian market. RZBC, Jungbunzlauer, Cargill, ADM, COFCO, and Gadot are also verifiable global producers. For domestic supply, representation status, inventory, the actual origin of the shipment, and the COA should be checked.

The table below is not a ranking. For foreign brands, an official page or product-introduction source is provided. For domestic production, current public data are more limited, and the status of the production line, capacity, and daily supply should be independently verified.

TTCA vs Ensign Citric Acid for Bulk Purchasing

Both companies offer Citric Acid Anhydrous and Monohydrate lines. The comparison should be based on the COA for the same shipment, granulation, standard, country and production location, production date, packaging, and delivered price. The brand name alone does not establish definite technical superiority.

Lemon Star vs RZBC Citric Acid for Industrial Purchasing

Lemon Star and RZBC both offer citric acid and citrate families. The buyer should compare the exact grade and Spec. In factories with several approved brands, incoming Trial results and a history of batch consistency are better criteria than brand reputation.

Applications of Citric Acid in Food and Beverage Industries; E330, pH Adjustment and Flavor

A large share of citric acid consumption is associated with the food and beverage industries. Citric acid creates a clean, familiar sour taste, adjusts pH, and forms complexes with metal ions. These three functions affect flavor, color stability, preservative behavior, and oxidation.

The FDA lists citric acid for functions such as pH Control Agent, Flavoring Agent, Sequestrant, and Antioxidant among substances added to food. The dosage must comply with the formulation and the regulations for the final product.

Citric Acid in Beverages and Fruit Juice

In beverages, the objective is not merely to create sourness. pH, flavor, sweetness, aroma, and stability must be adjusted together. Rapid dissolution and solution clarity are important for beverage lines. Fine granulation helps rapid dissolution but creates more dust.

Citric Acid in Jam, Jelly and Gummies

Acidity affects pectin gelation, flavor, and storage conditions. Excessive or late addition can alter texture. The formulation should be adjusted according to the type of pectin and soluble solids.

Citric Acid in Dairy Products and Processed Cheese

In some dairy products, citric acid or citrate salts are used for acidity and buffering. In processed cheese, sodium citrate more commonly acts as an emulsifying salt. Free acid and citrate salts are not complete substitutes for one another.

Citric Acid in Supplements and Effervescent Tablets

In effervescent tablets, citric acid reacts with bicarbonate and generates carbon dioxide. Low moisture in raw materials and the production environment is important for stability. For this reason, Anhydrous is the preferred choice in many dry formulations.

ADM presents citric acid for pH and flavor adjustment, flavor enhancement, antioxidant properties, and metal chelation in beverages, dairy products, supplements, and detergents.

Acidulants, Citric Acid and Citrates, ADM

Applications of Citric Acid in Detergents, Descalers and Industrial Scale Removal

Citric acid is used in detergents because of its acidity, solubility, and ability to complex calcium, magnesium, and certain metals. In descaling, the objective is to dissolve or loosen mineral deposits. In detergent formulations, it can also adjust pH and help control water hardness.

Compared with strong mineral acids, citric acid is milder for some applications, but this does not mean it is safe for every surface. Concentration, temperature, contact time, metal type, and rinsing should be determined by compatibility testing.

Citric Acid for Calcium Carbonate Scale

Carbonate scale forms in hard water, heat exchangers, equipment, and on surfaces. By lowering pH and forming complexes, citric acid can help dissolve these deposits. The required amount depends on the thickness and composition of the scale.

Citric Acid in Dishwasher Tablets and Household Detergents

In powdered products, the Anhydrous form is more suitable for moisture control. Compatibility with carbonates, silicates, and surfactants should be checked for stability and unwanted reactions.

Citric Acid in CIP and Equipment Cleaning

In some CIP systems, citric acid is used for acid cleaning and removal of mineral scale. Temperature, concentration, circulation time, and equipment material are decisive. The CIP program should be written based on the equipment manufacturer's instructions and a corrosion assessment.

Applications of Citric Acid in Pharmaceuticals, Supplements and Cosmetic Products

In pharmaceuticals, citric acid can act as an API, Excipient, buffer, chelating agent, or component of an effervescent system. Grade selection depends on the route of use and the product dossier. Pharmaceutical grade must comply with the stated monograph and required impurity controls.

In cosmetic and personal-care products, citric acid is used mainly for pH adjustment and, in some formulations, for a mild exfoliating effect. Final-formulation pH and skin compatibility are important. Industrial raw material without appropriate documentation should not be used in a cosmetic product.

Citric Acid USP in Pharmaceuticals

USP is an important reference for controlling identity, purity, and pharmaceutical-grade tests in the U.S. market and many international supply chains. A drug manufacturer should use the relevant monograph edition and the requirements of its own dossier as the reference.

Citric Acid Ph. Eur. in the European Market

For products with a European dossier, Ph. Eur. and GMP or Excipient requirements may apply. Jungbunzlauer has published information on GMP, CEP, and Type II US DMF for Citric Acid Anhydrous in pharmaceutical applications.

Citric Acid in Cosmetic Products for pH Adjustment

In shampoo, facial cleansers, creams, and certain solutions, a small amount of citric acid is used to reach the target pH. The amount added should be determined by pH measurement, not by a fixed recipe for all formulations.

Applications of Citric Acid in Water Treatment, Metalworking and Hardness Control

In aqueous systems, citric acid can act as an acid and complexing agent in cleaning, surface preparation, or metal-ion control. These applications should be coordinated with equipment materials and the site's chemical program.

In metalworking, citric acid is used for cleaning and some stainless-steel Passivation processes, but the result depends on the alloy, surface contamination, temperature, and time. Industrial use should follow a valid standard or instruction for the specific process.

Citric Acid for Water Hardness and Calcium and Magnesium Ions

Citrate can complex hardness ions in solution, but this is not the same as resin Softening or permanent hardness removal. In detergents, this behavior can reduce the effect of calcium and magnesium on surfactants.

Citric Acid for Metal and Stainless-Steel Cleaning

For stainless steel, the proper concentration and temperature must be matched to the alloy grade and surface contamination. Chloride presence, solution composition, and rinsing affect pitting corrosion.

Citric Acid in Plating and Industrial Baths

Citrate is used in some baths as a Complexing Agent or Buffer. Control of pH and metal concentration is important for bath stability. Free citric acid and citrate salts do not have identical roles.

Citric Acid Safety and Citric Acid SDS for Storage, Transport and Use

Citric acid is not considered flammable, but concentrated powder can irritate the eyes and respiratory tract. ECHA lists classifications related to eye irritation and respiratory irritation for citric acid in regulatory information. The SDS for the same brand should be the reference for PPE and emergency response.

Dust is generated during bag emptying and powder transfer. Local ventilation, controlled unloading, and industrial housekeeping reduce exposure. Safety goggles and gloves are appropriate for preventing direct contact with powder and concentrated solution.

Citric Acid PPE During Bag Emptying

PPE selection should start with the SDS. For routine work, safety goggles, gloves, and work clothing are generally sufficient. If significant dust is generated, respiratory protection should be selected based on exposure assessment and SDS instructions.

Citric Acid First Aid for Eye and Skin Contact

For eye contact, immediate and prolonged rinsing with water is important. Contaminated clothing should be changed. If symptoms persist, medical evaluation is required. The manufacturer's specific SDS instructions take precedence over general text.

Citric Acid Spill in the Warehouse

For dry powder, avoid creating a dust cloud. Collected material should not be mixed with sound product. For a solution, the spill should be contained and collected according to site regulations.

Citric Acid Packaging; 25 kg Bags, Pallets and Citric Acid Jumbo Bags

A 25 kg bag is one of the most common citric acid packaging formats. The bag structure may be multilayer paper with a polyethylene liner or laminated PP. The main purpose is to prevent moisture, contamination, tearing, and direct product contact with the environment.

For export orders or high volumes, some producers also offer 500 and 1,000 kg packages. TTCA lists 12.5, 25, 500, and 1,000 kg packaging in its technical sheet. RZBC also presents 25, 500, and 1,000 kg options.

25 kg Citric Acid Bags

Before delivery, check net weight, stitching, liner, brand printing, batch number, and production date. A wet or torn bag should not be accepted into storage merely after changing its outer appearance, because moisture can cause lumping and contamination.

Citric Acid Pallets for Domestic Transport

Pallet stacking should be uniform and secured with stretch film or a protective hood. The number of bags per pallet should be stated in the Packing List. A damaged pallet increases the risk of bag tearing and falling.

Inspection of Export Citric Acid Pallets Before Loading

For export, the English label, net weight, batch number, country of origin, and handling symbols should be checked. If wooden pallets are used, the destination's quarantine requirements and wood-packaging standard must also be reviewed.

Citric Acid Jumbo Bags for Tonnage Orders

Jumbo bags reduce the number of packages, but not every production line can unload them. The lifting-loop design, inner liner, and discharge spout must be compatible with factory equipment.

Citric Acid Storage Method and Prevention of Citric Acid Lumping

Citric acid should be stored in a dry, cool, and clean environment. An opened bag is quickly exposed to atmospheric moisture. A humid warehouse, floor contact, temperature fluctuations, and a punctured liner are the main causes of lumping.

Lumping does not always mean a loss of purity, but it makes dosing and dissolution more difficult. If lumping is accompanied by discoloration, odor, or package damage, contamination should be investigated.

Citric Acid Warehouse Humidity

Bags should be stored on pallets and away from walls. Roof leaks, floor washing, and container condensation should be controlled. In humid regions, pallet hoods and appropriate ventilation are more important.

FIFO Principle for Citric Acid Storage

Older stock should be used first. Batch number, receipt date, and production date should be recorded in the warehouse system. This makes complaint traceability and shelf-life control easier.

Conditions for Opening Citric Acid Bags

An opened bag should be used quickly or resealed. A dirty cutting tool or contaminated blade can introduce foreign contamination into the product. In food industries, tools and the unloading area should comply with the factory hygiene program.

Comparison of Citric Acid Brands TTCA, Ensign, Lemon Star, RZBC and Jungbunzlauer

Citric acid brand comparison should start with the Spec, not the trade name. Even if two brands both comply with FCC or USP, granulation, manufacturer internal limits, packaging, and batch consistency can differ. Price should be compared only after aligning the grade and delivery conditions.

TTCA, Ensign, Lemon Star, and RZBC are major Chinese producers. Jungbunzlauer, Cargill, ADM, and Gadot are also present in the global market. Choosing one brand for every application is not logical. A factory should build its Approved Vendor List based on Trial results and documentation.

If a factory has previously used one brand, a brand change should be made with a sample and Trial. Matching the Assay alone does not guarantee that dissolution time, flowability, or packaging behavior will be the same.

Citric Acid Export and Import; Citric Acid HS Code, COA and Purchasing Documents

In international trade, the six-digit HS code for Citric Acid is recognized as 291814. The national 8- or 10-digit code, import duties, and order-registration requirements must be confirmed for the country of origin and destination through a customs broker or official system.

Common documents include Commercial Invoice, Packing List, Certificate of Origin, COA, SDS, and, where required, food, Halal, Kosher, or Health Certificate documentation. Pharmaceutical grade may require additional documents.

Citric Acid HS Code 291814

This code is used for the international identification of Citric Acid. The buyer should not rely solely on a code recorded on an old invoice because national classifications and regulations may change.

Citric Acid COA in Import Purchasing

The COA should include the factory name, batch number, test date, parameter results, and approval by the producer's laboratory. For a large order, a pre-shipment sample or loading sample can be added to the contract.

Verification of Citric Acid COA Against the Shipment Batch Number

The batch number on the COA should be matched with the bag label and Packing List. If a shipment contains multiple batches, receiving one COA for the entire cargo without batch identification is not sufficient for quality control.

Citric Acid Packaging in Container Transport

Container humidity, bag tearing, and odor contamination are transport risks. Using sound pallets, proper stretch wrapping, and controlling Container Rain are important for humid routes.

Industrial Citric Acid Purchasing Guide and Bulk Citric Acid Order Checklist

Industrial citric acid purchasing begins by defining the application. The production unit should state whether the material is used for beverages, Dry Blend, pharmaceuticals, detergents, or descaling. Purchasing should then compare offers only on the same Spec.

If one seller offers Anhydrous FCC and another offers Monohydrate Industrial, comparing the price per kilogram has no technical meaning. Form, standard, brand, packaging, and delivery must be aligned.

Defining the Citric Acid Purchasing Spec

The Spec should state the anhydrous or monohydrate form, Assay, standard, limits for water, ash, oxalate, metals, granulation, packaging, and order quantity. Include only the parameters that actually matter to the process.

Citric Acid Sampling Before a Tonnage Order

For a multi-batch shipment, a sample should be taken separately from each batch. A retention sample should be sealed. In sensitive industries, Assay, moisture, appearance, solution clarity, and target contaminants should be tested before use.

Citric Acid Purchase Contract and Delivery Terms

The contract should clearly state the Spec, origin, brand, packaging, net weight, delivery time, delivery location, COA, inspection method, and dispute-resolution procedure. Terms such as export quality or first grade are not measurable criteria.

The table below summarizes the practical purchasing checklist. The key information in each row is explained in the paragraphs above.

Citric Acid Price Today and Factors Affecting Anhydrous and Monohydrate Citric Acid Prices

Citric acid price is not fixed and depends on the global market, brand, form, grade, exchange rate, importer inventory, freight cost, packaging, and order volume. Anhydrous and Monohydrate prices should be compared based on active material and application.

In factory purchasing, price per kilogram is only one variable. Irregular cargo, damaged bags, or granulation variation can increase storage, dissolution, and production-downtime costs. A low price without supply consistency is not a complete advantage.

Actual Citric Acid Cost in an Industrial Formulation

Actual cost is calculated based on consumption, waste, dissolution time, freight cost, and shipment rejection rate. Two offers with similar prices per kilogram can create different final costs for a factory.

Effect of Citric Acid Brand on Price

TTCA, Ensign, Lemon Star, RZBC, and European or American brands do not have the same pricing structure. Certifications, logistics cost, production location, and regional inventory affect price.

Effect of Anhydrous and Monohydrate Citric Acid Form on Price

Monohydrate contains water of crystallization and has a higher molar mass than Anhydrous. For stoichiometric formulations, cost comparison should be based on an anhydrous-acid equivalent.

Effect of Food and Pharmaceutical Grade on Citric Acid Price

Pharmaceutical grade usually requires more control and documentation. This can increase the price. Purchasing a grade higher than necessary also creates additional cost.

Effect of Citric Acid Order Volume on Tonnage Price

A full truck or container order reduces unit transport and handling costs. Purchasing a few bags from local inventory has a higher unit price but lowers the risk of excess inventory.

Why Is Buying Citric Acid from Shimico Suitable for Price Inquiries and Bulk Sales?

Shimico is a B2B platform for buying and selling chemicals. An industrial buyer can state the citric acid form, grade, brand, quantity, packaging, and delivery location in one purchase request and compare supplier offers on the basis of the same specifications.

Shimico does not replace the laboratory or a technical contract. The COA, sample, producer documents, and delivery terms must be reviewed by the buyer. The platform's advantage is shortening the path to finding sellers and creating comparable requests.

Submit a Citric Acid Purchase Inquiry on Shimico

In the inquiry, state Anhydrous or Monohydrate, Food or Pharma grade, standard, acceptable brands, quantity, destination, and any need for pallets or special packaging. These details improve the quality of the offers.

Post a Citric Acid Sales Listing on Shimico

The seller should specify the brand, form, grade, country of manufacture, packaging, minimum order, loading location, COA, and sample availability. A vague listing increases negotiation time.

Citric Acid Buyer Reviews from Shimico

Incoming Inspection of Citric Acid at the Factory and Citric Acid Shipment Acceptance Testing

Incoming citric acid control should be performed before complete unloading or use on the production line. The warehouse unit does not merely receive the number of bags. Brand name, anhydrous or monohydrate form, grade, batch number, production date, net weight, liner integrity, and COA must be matched against the purchase order. If the cargo contains multiple batches, each batch should be recorded as a traceable unit.

At a food factory, representative sampling from several bags is important. A sample from one bag among hundreds cannot represent the entire shipment. Primary samples should be taken from different pallet locations and, after mixing, divided into a test sample, retention sample, and dispute-resolution sample. Sample containers must be dry, clean, and labeled with the batch code.

Visual Inspection of Citric Acid Before Warehouse Entry

The product should be white or colorless, crystalline, and free from abnormal odor. Soft lumps caused by pressure are not the same as moist lumps or discoloration. Stains, foreign particles, unusual chemical odor, or signs of moisture on the bag should be recorded. Photos of the damaged pallet and batch number are useful documentation for supplier follow-up.

Rapid Citric Acid Testing in the Factory Laboratory

Depending on the application, the incoming laboratory can check appearance, solution clarity, pH of a solution at a specified concentration, moisture, and Assay. Sensitive pharmaceutical and food industries may also examine metals, oxalate, or microbiological and endotoxin tests according to the Spec. The test method should remain consistent so that results from different batches are comparable.

Citric Acid Retention Sample for Tonnage Purchasing

A retention sample from each batch should be stored with the date, supplier, batch number, and order number on the label. The retention period should comply with the factory's quality-control policy. If a complaint about solution color, lumping, or formulation performance arises, the retention sample makes it possible to compare with the consumed cargo and takes the dispute beyond guesswork.

Comparison of Citric Acid with Malic, Lactic and Phosphoric Acids for Industrial Acid Selection

Citric acid is not always the best acid for every formulation. Choosing among citric acid, malic acid, lactic acid, and phosphoric acid depends on flavor, acid strength, buffering, chelation, regulations, and price. The comparison should be based on performance in the final product, not only on the price per kilogram of raw material.

In beverages, citric acid creates a rapid and familiar sour taste. Malic acid usually provides a longer-lasting sourness and may be more suitable for certain fruit flavors. Lactic acid creates a milder acidity and is used in food, fermentation, and detergents. Phosphoric acid is used in cola beverages and some industrial processes because of its different flavor profile and chemistry.

Comparison of Citric Acid and Malic Acid in Beverages and Gummies

Citric acid has a bright, rapid onset of sourness. Malic acid can create a more persistent sourness. Confectionery and beverage manufacturers sometimes combine the two to build a flavor profile. One-for-one substitution without sensory and pH testing is not recommended because acid strength and buffering behavior are not the same.

Comparison of Citric Acid and Lactic Acid in Detergents and Food

Both acids are used for pH control and in certain cleaning formulations. Citric acid provides stronger chelation for some metal ions. Lactic acid is liquid and has a different feeding method. Selection depends on dosing equipment, the surface being cleaned, and the formulation objective.

Comparison of Citric Acid and Phosphoric Acid in Industrial Purchasing

Phosphoric acid is a mineral acid and has different corrosion behavior, acid strength, flavor, and ionic residue. In food products, beverage type and regulations are decisive. In industrial cleaning, metal type and scale type also determine which acid is more suitable. A lower acid price should not replace compatibility and performance testing.
