Customs clearance of Nylon types: HS Codes 392321, 392329, 392690 + documents & permits

Nylon (Nylon) is a widely used polymer product across packaging, agriculture, and industry, and holds a special place in international trade. Thanks to standout properties—moisture resistance, flexibility, and long service life—nylon is valued by many manufacturers and end users. Therefore, understanding the customs clearance process for nylon is essential for importers and exporters.

1) Types of nylon and applications

1. Packaging nylons

Due to moisture resistance and clarity, these are used in food, pharmaceutical, and consumer industries—for food packaging, hygiene products, and medicines.
HS Code: 392321
Uses: food packaging, hygiene items, medicines, consumer goods

2. Agricultural nylon

Mainly used for greenhouse films protecting crops against weather. By blocking UV and sunlight to controlled levels, they help crop growth.
HS Code: 392329
Uses: greenhouse covers, agricultural product packaging, on-farm uses

3. Industrial nylon

With high abrasion resistance and heat tolerance, used in automotive and industrial parts—gears, bearings, etc.
HS Code: 392690 (varies by type/compound)
Uses: gears, bearings, automotive and machinery parts

4. Multi-layer nylon films

Used for vacuum packs and foods needing longer shelf life; multiple layers boost strength and barrier.
HS Code: 392329
Uses: vacuum packs, foods, medical products

5. Bubble wrap

For shock-sensitive items (electronics, fragile parts). Air bubbles cushion against impact.
HS Code: 392329 or 392390 depending on type
Uses: electronics, fragile & sensitive goods

6. Printed nylon

For branded/advertising packaging; supports color and graphic prints.
HS Code: 392329
Uses: branded packaging, promo & retail bags

7. Recycled nylon

Produced from post-use nylon; used in industrial packaging, plastic bags, and films.
HS Code: 392690 (depends on final product)
Uses: plastic bags, industrial packaging, films

8. UV-resistant nylon

For agriculture and construction where protection from direct sun/UV is required.
HS Code: 392329
Uses: greenhouse covers, agri packaging, construction

9. Heat-resistant nylon

For high-temperature service in automotive and industrial components, retaining physical properties.
HS Code: 392690
Uses: auto parts, industrial equipment, electrical goods

3) Key steps and notes for nylon clearance

Customs valuation: Based on type, application, and origin. Provide valid documents—commercial invoice, B/L, and Certificate of Origin—for accurate valuation.
Import permits: Some nylons (e.g., for food/agri use) may require environmental or health permits from relevant authorities.
Proper packaging: Typically shipped in large rolls; adequate packaging prevents transit damage and meets international standards.
Standards compliance: Many countries have specific nylon import standards; compliance helps avoid clearance issues.

4) Special import/export conditions for nylon

Given the variety of industrial/commercial uses, nylon imports/exports face country-specific requirements. Knowing these helps shape a winning trade strategy.

Imports into Iran
Iran is a major nylon consumer in the region, importing largely from China, Turkey, UAE, Germany, and South Korea—key global producers—serving high demand in packaging, agriculture, and industry.

Exports from Iran
Iran has advanced significantly in nylon production—especially packaging and agricultural grades—and exports to Iraq, Afghanistan, Pakistan, Turkey, and GCC states, aided by geographic proximity and industrial demand.

5) Import/export volumes into Iran

Customs data show rising nylon imports into Iran in recent years, driven by packaging and agriculture—totaling tens of millions of USD annually. Exports have also grown, leveraging domestic production to expand regional markets.

6) Nylon in global trade

As a high-volume polymer, nylon commands significant global turnover. China is the largest producer, and the market spans packaging, automotive, electronics, and agriculture—worth billions of dollars annually.

7) Top exporters and importers worldwide

Leading exporters
Besides China, Germany, the U.S., South Korea, and Japan have strong positions—supplying high-quality, diverse products.

Leading importers
The U.S., Mexico, Brazil, Canada, and European countries import large volumes to meet industrial/consumer demand for high-quality nylon.

8) The best, simplest way to clear nylon

Consult customs experts: Experienced advisers help pick the correct HS, obtain permits, and avoid pitfalls.
Prepare a complete file: Provide commercial invoice, B/L, CO, and any required import permits (standards, environment).
Use e-customs platforms: Systems like Iran’s national trade portal streamline online declarations, cutting time/cost and minimizing data errors.
Track every step: Stay in touch with customs for valuation and duty payment to avoid delays.
