🏭 Polyamide Primary Forms (Nylon Granules/Pellets)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 Part 1: Product Definition & Classification: Do You Really Understand "Polyamide Granules"?
Polyamide, commonly known as Nylon, is a synthetic polymer belonging to the family of polyamides. In international trade, "Primary Forms" refer to raw materials in basic shapes such as liquid, powders, flakes, granules, or pellets, rather than finished fibers, films, or molded parts.
These granules are the fundamental building blocks for manufacturing textiles, automotive parts, engineering plastics, and 3D printing filaments.
⚠️ Key Distinction Point: * Polyamide 6 (PA6) & Polyamide 6,6 (PA66): The most common types, falling under different sub-headings. * Other Polyamides: e.g., PA11, PA12, PA6,10, etc., fall under "Other". * Finished vs. Raw: If the product is a fiber (nylon thread) or fabric, it does NOT belong here. It must be in primary form (granules/powder).
📦 Part 2: HS Code Classification Details (2026 Latest Tariff Authority Match)
| HS Code | Product Description | Application Scenario | Chemical Type |
|---|---|---|---|
3908.10.00.00 |
Polyamides-6, -10, -11, -12, -6,6, -6,9, -6,12, -11,11 or -12,12, in primary forms | Standard engineering plastics (PA6, PA66) | Aliphatic Polyamides |
3908.90.00.00 |
Other polyamides in primary forms | Specialty nylons (e.g., PA46, PA4T, Liquid Crystal Polymers - LCP) | Other Polyamides |
🔍 Important Note: * 3908.10 covers the vast majority of commercial nylon granules (PA6 and PA66). * 3908.90 is for "specialty" nylons not listed in 3908.10. * Do not confuse with 3907 (Polyacetals/Polyesters): Ensure the product is chemically a polyamide (contains -CONH- linkages).
💰 Part 3: 2026 Latest Tariff Rate Details (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: United States (US) ✅ Country of Origin: China (CN) ✅ Effective Date: Starting November 10, 2025 (for subsequent imports)
🎯 1. 3908.10.00.00 —— Polyamide-6, -6,6, etc. (Primary Forms)

📌 Note: * Applies to specialty nylons like PA46 (high heat), PA12 (flexible), or LCP (liquid crystal polymer). * Even though it's "other," it faces the same surtax structure as standard PA6/PA66.
🛠️ Part 4: Customs Clearance Practical Advice (Avoid Pitfalls)
✅ 1. Required Documentation Checklist (Essential)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must state Chemical Name (e.g., Polyamide 6), Melting Point, Viscosity/Intrinsic Viscosity. |
| ✅ Formula/Composition | ✔️ | Confirm no significant additives that change the classification (e.g., >5% carbon fiber might change classification to 3926). |
| ✅ Product Photos | ✔️ | Show granules/powder form. Label should show "Polyamide 6 Granules". |
| ✅ Certificate of Origin (CO) | ✔️ | To prove country of origin. If from Vietnam/Malaysia, may apply for lower rates. |
| ✅ Commercial Invoice | ✔️ | Clearly describe as "Polyamide 6 Granules, Raw Material for Injection Molding". |
| ✅ Packing List | ✔️ | Detail net/gross weight and packaging type (usually 25kg bags). |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 "Granules Only, No Fibers, Name Specific, Tax Avoids Errors!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Nylon 6 Granules | 3908.10.00.00 |
Misclassified as "Plastic Parts" (3926) → Higher risk |
| Nylon Fabric/Film | 5407 or 5404 |
Declare as "Granules" → Seizure Risk |
| Nylon + Glass Fiber (>5%) | 3926.90 (Other Plastic Articles) |
Declare as "Pure Polyamide" → Penalty |
| Recycled Nylon Pellets | 3908.10.00.00 |
May require extra proof of recycling status |
💡 Critical Warning: * If the granules are compounded with more than 5% of other materials (like glass fiber, carbon fiber, or flame retardants) that significantly alter the character, it might shift to Chapter 3926 (Other articles of plastics), which has different duty rates and regulations. * Pure virgin granules go to 3908.
✅ 3. Special Cases
| Situation | Handling Advice |
|---|---|
| Recycled Nylon | Still 3908.10.00.00 if in primary form, but provide proof of recycling process. |
| Color Masterbatches | If mixed with pigment in large quantities, may be classified as "preparation" (3207), but usually still 3908 if polymer is main component. |
| 3D Printing Filament | If cut into filament form, it is NOT primary form. It falls under 3916 (Monofilament/Solid Rods) → Different duties! |
🌍 Part 5: Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification Required | Remarks |
|---|---|---|---|---|
| 🇺🇸 USA | 3908.10.00.00 |
22.8% | No special cert | High tariff due to 301 + IEEPA |
| 🇨🇳 China | 3908.10.00.00 |
0% (Import) | None | Major producer/consumer |
| 🇪🇺 EU | 3908.10.00.00 |
6.5% | REACH (SVHC) | Standard EU import duty |
| 🇦🇺 Australia | 3908.10.00.00 |
5.0% | None | Low tariff, FTAs may apply |
| 🇯🇵 Japan | 3908.10.00.00 |
5.3% | PSE (if electrical parts later) | Stable import regime |
📌 Conclusion: * The USA imposes the highest burden on Chinese polyamide imports due to layered tariffs. * For US-bound goods, consider sourcing from Vietnam, Thailand, or India to potentially avoid the 7.5% + 10% surcharges, provided the Rules of Origin are strictly met.
📌 Part 6: Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring "Plastic Pellets" without specifying "Polyamide" 👉 Consequence: Customs may classify under generic 3902-3914 codes, leading to audit and back taxes.
❌ Mistake 2: Confusing Nylon Granules with Nylon Filament 👉 Consequence: Filament is 3916, Granules are 3908. Different duties and regulatory requirements. Wrong code = Seizure.
❌ Mistake 3: Ignoring Additives 👉 Consequence: If the granules contain >5% glass fiber, they are 3926, not 3908. Misclassification leads to penalties.
❌ Mistake 4: Under-declaring Value 👉 Consequence: Tariff is ad valorem. Low declaration triggers Customs Valuation Investigation.
✅ Correct Practice:
"Polyamide 6 (PA6) Virgin Granules, Intrinsic Viscosity 2.8, White Color, 25kg PP Bag, Raw Material for Injection Molding, Made in China"
🎯 Part 7: Conclusion: Precision in Classification Saves Money!
🎯 Remember the Mantra:
🔹 "Granules = 3908, Filaments = 3916, Additives >5% = 3926!" 🔹 "China to US = 22.8%, Check Origin, Avoid Surtaxes!"
📌 Pro Tip: If you are importing large volumes into the US, consider applying for an Exclusion from Section 301 tariffs if available, or structure your supply chain through Third Countries (Vietnam, Malaysia) to leverage FTAs and avoid IEEPA surcharges. Always request a Binding Ruling from CBP before shipping if the product composition is complex.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
