Sulfuric Acid (H2SO4) in Iran: Daily Price, COA/MSDS, Bulk Purchase & Export via Shimico
Sulfuric acid is one of the most important and widely used basic chemicals in the chemical industry and plays a vital role across many production chains in Iran and worldwide. This colorless mineral acid is highly corrosive and reactive, with the chemical formula H2SO4, and is produced in multiple concentrations (98%, 92–96%, and more diluted grades).
In Iran, sulfuric acid is essential for major sectors including copper production, chemical fertilizers, refineries, petrochemicals, metal industries, paint and resin, catalysts, rubber, and industrial water and wastewater treatment.
A significant share of national supply comes from refinery desulfurization units, acid plants of copper complexes (such as Sarcheshmeh and Khatoon Abad), and dedicated chemical plants. As a result, sulfuric acid is consistently among the most traded industrial acids in the Iranian market for purchase, sales, and export.
Grades of Sulfuric Acid in Iran
Iran commonly supplies three core grades. Differences are driven by production route, purity, stability, and industrial use.
1) Sulfuric Acid 98% (Sulfur-Based, Industrial Grade)
The highest-purity and most widely used grade. Typically clear and colorless; preferred in sensitive and higher-spec processes. Often produced from sulfur or sulfur-bearing gases.
- Phosphate fertilizer production
- Paint and resin
- Metal extraction and leaching
- Basic chemical synthesis
- Battery manufacturing
2) Sulfuric Acid 92–96% (Copper Industry By-Product)
Produced in copper complexes such as Sarcheshmeh, Sungun, and Khatoon Abad as a by-product of smelting/desulfurization. Often slightly darker than 98% and suitable for general industrial uses.
- Industrial washing
- General metalworking processes
- Industrial detergents
- General, non-sensitive applications
3) Diluted Sulfuric Acid (30–60%)
Used where a strong concentrated acid is not required. Lower hazard compared to concentrated grades; commonly used for pH adjustment and lighter industrial applications.
- pH control in water and wastewater
- Limited/controlled food-related applications
- Fibers and textiles
- Laboratory and semi-industrial uses
Key Differences Between Sulfuric Acid Grades
| Grade | Main Characteristics | Typical Applications |
|---|---|---|
| 98% (Sulfur-Based) | Clear and colorless, high purity, stable quality, suitable for sensitive industries | Phosphate fertilizers, metal extraction/leaching, paint & resin, battery manufacturing |
| 92–96% (Copper By-Product) | Medium purity, slightly darker, suitable for general industrial use | Industrial washing, metalworking, industrial detergents, non-sensitive processes |
| 30–60% (Diluted) | Lower concentration, safer handling, suitable for controlled dosing and pH adjustment | Water/wastewater pH control, light industries, laboratories |
Sulfuric Acid Production in Iran
Iran is a key sulfuric acid producer in the region. Domestic supply is primarily supported by three sources:
- Refinery sulfur/desulfurization units: typically produce high-purity 98% sulfuric acid.
- Copper complexes: produce 92–96% as a by-product during smelting and desulfurization.
- Chemical plants: independent facilities producing various grades with medium capacities.
Main consumption is tied to fertilizer manufacturing, refineries, metal extraction, basic chemical production, and industrial water treatment. Recent capacity expansions have improved local supply availability for industrial purchase and bulk sales.

Product Quality: What to Look For Before You Buy
Quality is strongly associated with appearance and unexpected odors. High-quality sulfuric acid is colorless and transparent. Yellow or brown tint may indicate quality degradation or contamination, which can affect corrosion rate, reaction consistency, and downstream product quality.
Production Method (Industrial Overview)
Industrial sulfuric acid in Iran is predominantly produced via the Contact Process, where sulfur compounds are oxidized and processed through controlled stages to obtain stable, high-purity acid. A notable portion of 92–96% supply is also produced as a copper-industry by-product and is commonly used in general industrial applications.
Industrial Applications of Sulfuric Acid
Due to strong acidity, chemical stability, and economic cost, sulfuric acid is used across heavy and foundational industries as well as medium and specialized production lines. It is central to sulfate salts, catalyst systems, battery electrolytes, paint/resin chemistry, and pH reduction/neutralization in water treatment.
Sulfuric Acid Applications by Industry
| Industry | Type of Use |
|---|---|
| Chemical industries | Production of sulfate salts; catalyst production; cleaning agent for scale and deposits |
| Battery industry | Electrolyte for lead-acid batteries |
| Paint & resin | Solvent/process aid and acidity regulator in paints, inks, glazes |
