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

Thiocarbamates are among the most important modern chemical compounds, widely used across sectors such as agriculture, mining, and the chemical industry. Owing to their unique properties, they play a key role in industrial processes like herbicide production and mineral flotation. Since thiocarbamates fall under specialized-use chemicals, their import and export require strict adherence to customs regulations and specific licensing.

1) Detailed Description: What Are Thiocarbamates and Why Do They Matter?

  • A family of sulfur-containing organic compounds with broad industrial applications.
  • Key role in herbicide manufacture and in mineral flotation processes for metal separation.
  • Specialized in nature and require strict compliance with customs rules and relevant permits for import/export.

2) Types and Applications

Agriculture:
Thiocarbamates are used as active substances in herbicides and fungicides. Thanks to their specific chemical behavior, they can control a wide range of weeds and farm pests. By using these agents, farmers can increase crop yields and avoid losses caused by destructive factors. A notable advantage of thiocarbamates is their selective toxicity: they target harmful plants while sparing desired crops.

Mining:
In mining, thiocarbamates are used in the flotation process to separate and concentrate precious and base metals such as gold, silver, copper, and others. Acting as collectors/frothers, they aid in separating valuable metals from gangue. This process is vital to extraction efficiency, improving operations and enabling optimal use of natural resources.

Chemical Industries:
Thiocarbamates are also employed as raw materials or catalysts in the production of rubber, plastics, and other chemicals. Due to their stable physicochemical properties, they are very effective in manufacturing industrial products that demand resistant materials enhancing product quality and process performance.

3) Key Points in Customs Clearing Thiocarbamates

Customs Tariff (HS Code)

Selecting the correct HS code is critical for clearing any chemical. Thiocarbamates are generally classified under 293090, which covers related structured compounds. Choosing the right code helps importers/exporters benefit from tariff preferences and tax exemptions, minimizing import costs.

Required Permits for Import & Export

Given environmental sensitivities and specific industrial uses, thiocarbamates may require permits from state bodies. Depending on whether they are destined for agricultural or chemical use, approvals may be needed from organizations such as the Department of Environment, the Ministry of Agriculture Jihad, and the Ministry of Industry, Mine & Trade. For exports, special export permits or international health/quality certificates may also be required.

4) Customs Tariff / HS Code

Goods Short Description HS Code
Thiocarbamates Sulfur-containing organics for ag/mining uses 293090

Final classification depends on exact type, purity, form, and declared end use.

5) Special Conditions for Import and Export of Thiocarbamates

Importing Thiocarbamates into Iran:
As key feedstocks for Iran’s agriculture and mining sectors, thiocarbamates are vital to industrial supply. Because these substances can impact the environment and public health, their import is tightly regulated. This includes rigorous environmental assessments to ensure safety and prevent potential risks.
To import thiocarbamates into Iran, importers must obtain specific permits from relevant authorities. The most important include:
Department of Environment (DOE) permit: Evaluates environmental impacts to prevent potential hazards.
Ministry of Agriculture Jihad permit: Required due to extensive use in herbicide and fungicide production.
Ministry of Industry, Mine & Trade (MIMT) permit: Governs imports used in mining and chemical industries.

6) Iran Market: Imports, Exports, and Destinations

Exports of Thiocarbamates from Iran:
Thanks to access to raw materials and growing production capabilities, Iran has become a regional producer of thiocarbamates. Exports are significant due to high product quality and global demand, with destinations including Iraq, Afghanistan, and certain Middle Eastern and Central Asian markets. Leveraging competitive advantages, Iran has emerged as a key player in export markets.

Export Volumes from Iran:
Shipments from Iran to neighboring and regional markets are on the rise. Based on export data, hundreds of tons are exported annually to international markets—mainly to countries with developed agricultural and mining industries that need these substances as inputs.

7) Trade Volumes: Iran’s Imports and Exports

Import volumes depend on sectoral demand. Generally, thousands of tons of thiocarbamates are imported each year to supply agriculture, mining, and chemical industries. With rising demand in ag production and expanding mining activity, imports are increasing.

8) Global Market: Major Exporters and Importers

The global thiocarbamates market is growing steadily, driven by rising demand in agriculture and mining. Worldwide production and consumption continue to expand. Global turnover reaches the billions of dollars, with producing nations such as China, India, the United States, and some European countries holding major shares. Through scale and advanced technologies, these countries meet international demand and export broadly.
Global Exporters of Thiocarbamates
China is the largest producer and exporter, leveraging mass production and low costs to command a major market share. Other key producers/exporters include India, the United States, Germany, and France—each playing pivotal roles thanks to technological advances and feedstock access.

Global Importers of Thiocarbamates
Developed agricultural and mining markets are the principal importers. Countries with advanced agriculture—such as Brazil, Argentina, and Mexico are major buyers. European countries including Spain, Italy, and France with sophisticated mining and chemical industries also import for process optimization.

9) Required Documents for Clearing Thiocarbamates

Clearing thiocarbamates from customs requires a set of documents—without which the process will face issues and delays. 
1. Commercial Invoice
A primary document for customs that must include price, quantity, and full product specifications. The more detailed the invoice, the faster the clearance. It should contain complete information about seller, buyer, and the product.

2. Packing List
Shows how goods are packed. It lists the number of packages, packaging type, and net/gross weights. This is vital for inspection at clearance.

3. Certificate of Origin
Confirms the country where the goods were produced. Especially important when Iran has trade agreements with the origin country to obtain tariff preferences. Issued by the Chamber of Commerce or an accredited body in the producing country.

4. Certificate of Analysis (COA)
Crucial for chemicals like thiocarbamates. Specifies composition and quality; usually issued by accredited labs. Customs rely on it to ensure safety and quality. Absence of a COA likely causes delays.

5. Customs Declaration
An essential filing where the importer/agent officially declares all details to customs, including HS code, type and quantity, and technical specs.

6. Import Permits
Depending on type/use, specific government permits may be required, such as:
Department of Environment permit; Ministry of Agriculture Jihad permit (for ag uses like herbicide/fungicide manufacture); and Ministry of Industry, Mine & Trade permit (for industrial/mining uses).

7. Bill of Lading
Issued by the carrier, indicating transport mode, origin/destination, and shipment details. Without a B/L, customs cannot verify proper carriage leading to delays.

8. Health Certificate
May be required for agricultural applications confirms fitness for use in ag products.

9. Insurance Policy
Ensures coverage against transit risks, minimizing financial exposure in case of incidents.

Key Tips & Practical Recommendations

  • Prepare a valid COA and up-to-date Safety Data Sheets (SDS) from the outset to speed inspection.
  • Align the HS code with trade description, purity, and end use to avoid tariff disputes.
  • For agricultural uses, coordinate early with the Ministry of Agriculture Jihad and secure health certificates.
  • Ensure packaging/labeling complies with chemical transport standards.
