Customs Clearance of Sulfites in Iran (HS Code + Documents & Permits)
Sulfites are fundamental inorganic chemicals with wide industrial use. They are acidic salts derived from sulfurous acid and, thanks to their specific properties, are used across many processes. Sulfites appear as white powders, crystals, and sometimes as solutions; depending on type and form, they serve a broad range of industrial applications.

Sodium Sulfite:
One of the most widely used sulfites, valued for its strong reducing properties. Uses include photography (as a reducer), textiles and papermaking (as a bleaching agent), and as a preservative in food. It also acts as an antioxidant to prevent oxidation and spoilage.
Potassium Sulfite:
Used mainly as a preservative and stabilizer in food. By inhibiting microbial growth and oxidation, it helps maintain product quality. It is also used in beverage production to stabilize color and flavor.
Ammonium Sulfite:
Applied in textiles and leather as a bleaching agent, and in chemical synthesis as an intermediate. It also finds use in photography for image stabilization.
2) Technical & Structural Properties
Owing to their unique chemistry, sulfites possess strong antioxidant and reducing characteristics—ideal for many uses. In food, they help preserve color, taste, and freshness; in chemical processing, they work as reducing and stabilizing agents.
3) Specialist Tips for Clearing Sulfites Through Iranian Customs
Because of their chemistry and widespread applications (food, pharma, chemical, paper), sulfite consignments require expert handling and precise compliance during clearance. Below are key points:
1. HS (Tariff) Codes
HS codes determine duties, classification, and applicable import/export rules. For sulfites, 2832.10.90 and 2832.10.10 are commonly used. Exact coding depends on the specific cation (e.g., sodium, potassium, ammonium) and the intended use (e.g., food/pharma). Accurate classification requires technical documentation, chemical specs, and consultation with customs experts.
2. Required Documentation
Complete, accurate paperwork is critical:
Certificate of Origin (CO): Identifies the country of manufacture; normally issued by the origin country’s chamber of commerce—important for preferential tariffs and compliance.
Certificate of Analysis (CoA): Details composition, purity, and technical specs; typically issued by accredited labs to verify product quality.
MSDS (Material Safety Data Sheet): Comprehensive safety information, hazards, handling, storage, and transport instructions—mandatory for chemical imports. Proper documentation prevents delays and eases clearance.

3. Standards Compliance & Health Permits
Given their use in sensitive sectors like food and pharma, imports must meet strict national and international standards. For food/pharma applications in Iran, health permits from the Iran Food and Drug Administration (IFDA) are obligatory, confirming safety and compliance.
4. Health Tests & Quality Control
Due to sensitivity across uses, sulfites may require stringent health and QC testing—e.g., purity assessment, heavy metals, and microbiology. These ensure consumer safety and that imports meet domestic and international quality expectations.
4) Exporting & Importing Countries
Imports into Iran: Primarily from China, Germany, India, and the USA—key suppliers with advanced technology and scale.
Exports from Iran: Shipments go to neighboring and select Middle Eastern markets. While volumes are smaller than imports, Iran is recognized as a regional producer.

5) Special Conditions for Importing Sulfites into Iran
Given sensitive applications, importers must:
Obtain required permits: From relevant bodies such as IFDA and the Institute of Standards & Industrial Research of Iran (ISIRI).
Pass health controls: Imported products may undergo rigorous testing to confirm absence of contaminants or harmful substances.

| Goods | Short description | HS Code |
|---|---|---|
| Sulfites (other) | Acid salts of sulfurous acid | 2832.10.90 |
| Sodium / Potassium / Ammonium sulfite (examples) | Food, textile, papermaking uses | 2832.10.10 |
Final subheading depends on the cation (Na/K/NH4), purity, grade, and end use.
