Customs Clearance of Polycarboxylic Acids in Iran (HS Code + Documents & Permits)

Polycarboxylic acids are a group of chemical compounds that, due to having more than one carboxyl group (–COOH), have wide applications across various industries. Owing to their unique chemical properties—such as high solubility, catalytic activity, and the ability to form strong chemical bonds—they are of special importance. Applications include the production of polymeric materials, paints, coatings, and pharmaceutical additives. Because of legal and technical sensitivities, clearing these materials from customs requires precise familiarity with regulations and customs procedures.

1) Applications of Polycarboxylic Acids

Polycarboxylic acids are used in many industries due to their unique physical and chemical properties. Key applications include:
Paints & Coatings: These acids serve as core components in producing durable paints and coatings. Multiple carboxyl groups create stronger chemical bonds, enhancing resistance to corrosion, moisture, and UV.
Polymers & Plastics: Used as modifiers in engineering polymer production. They can improve heat resistance, mechanical properties, flexibility, and service life. Also used in industrial adhesives and specialty plastics.
Pharmaceuticals & Biotechnology: Utilized in drug formulations and dietary supplements. Thanks to high affinity and interactions with other compounds, they can increase drug efficacy and improve biological processes.
Detergents & Cleaners: As active agents in detergent formulations, they help dissolve and remove oils and contaminants—used in both industrial and household cleaners.

2) Key Points in Clearing Polycarboxylic Acids

Clearance requires complying with specific rules, from collecting documents to obtaining permits. Highlights:

Required Documents

Commercial documents such as invoice, bill of lading, and certificate of origin are essential. Technical documents like chemical analysis and health certificates must be provided to relevant authorities. Selecting the correct HS code is critical. Polycarboxylic acids are commonly classified under HS 2917.39.

Special Permits

Some polycarboxylic acids may require special permits from health and regulatory bodies due to their chemistry and uses—for example, approvals from Iran’s Department of Environment or Ministry of Health.

Customs Tariff (HS Code)

Determining the HS code impacts import duties and taxes. While many fall under HS 2917.39, some specific acids may be classified under 2917.19.

3) Special Conditions for Import/Export

Import into Iran

Iran relies heavily on importing polycarboxylic acids from industrialized countries such as China, Germany, and the United States. China, as the largest global producer/exporter, supplies a significant share of Iran’s needs. These materials are in demand across paints/coatings, plastics, pharma, and detergents. With the growth of these industries, imports have risen notably in recent years.

Import/Export Volumes Involving Iran

Available data suggest Iran’s imports total roughly 2,000–3,000 tons annually in recent years, tied to domestic industrial demand. Exports from Iran to countries like Turkey, the UAE, and Central Asian states are also rising—averaging around 1,000 tons per year.

Global Circulation

Global trade of polycarboxylic acids is rapidly increasing due to diverse industrial uses, reportedly exceeding 20 million tons per year, driven by industrial growth in countries like China and India.

Major Exporters

China: the largest producer/exporter with high capacity and advanced infrastructure. Germany: a leading exporter with high-quality output. United States: another key producer/exporter with strong chemical/petrochemical industries.

Major Importers

India: rapidly growing demand in pharma, plastics, and chemicals. South Korea: advanced chemical/petrochemical industries with high demand. Brazil: a developing market in South America with steady imports.

4) Documents Required for Clearance

The following documents are essential for import and clearance, to ensure legality, safety, and compliance:
1. Commercial Invoice: Includes price, quantities, total value, and product specifications.
2. Bill of Lading: Issued by the carrier; shows weight, number of packages, and final destination.
3. Certificate of Origin: Indicates the country of production; usually issued by the exporter’s chamber of commerce.
4. Certificate of Analysis (COA): Confirms chemical composition and technical specs; issued by the manufacturer or accredited labs.
5. Health & Safety Certificates: Evidence that the product is safe for intended industrial use, issued by relevant authorities.
6. HS Code: Polycarboxylic acids are commonly classified under HS 2917.39.
7. Special Permits: Where applicable—e.g., Ministry of Health, Department of Environment—especially if hazardous/sensitive.
8. Insurance Policy: Covers potential losses during transport.
9. Customs Declaration: Accurate, complete declaration of goods and value to the customs authority.
