🧬 High Weather-Resistant Polyamide Raw Material (Engineering Plastics)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Polyamide Raw Material"?
Polyamide (PA), commonly known as Nylon, is a versatile synthetic polymer widely used in automotive, electronics, and textile industries. However, in international trade, "Raw Material" is a broad term that requires precise classification based on its physical form and state of processing.
For High Weather-Resistant Polyamide, the key to correct classification lies in determining whether it is: 1. Primary Form (Resins/Granules): Unpolymerized or pre-polymerized pellets ready for molding. 2. Secondary Form (Compounded): Granules mixed with additives (UV stabilizers, carbon fiber, glass fiber) to enhance weather resistance.
⚠️ Critical Distinction:
- If it is pure polyamide resin (primary form) → Typically classified under 3902.10.
- If it is polyamide with added stabilizers/fillers (compound) → Typically classified under 3901-3914 depending on whether it is a distinct copolymer or a blend.
- Note: "Weather resistant" is a property, not a structural feature. Customs does not classify by "weather resistance" alone but by the chemical composition and form.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Physical Form |
|---|---|---|---|
3902.10.00.00 |
Primary forms of Polyamides (Nylon 6, Nylon 6,6, etc.) | Pure resin pellets, base raw material for injection molding | ✅ Granules/Powder |
3904.61.00.00 |
Primary forms of Polyamides (Other, e.g., Nylon 11, 12, PA4,6) | Specialized engineering plastics, often with better chemical/weather resistance | ✅ Granules/Powder |
3901.90.00.00 |
Primary forms of Polymers of Ethylene (If mistaken for PE) | ❌ Wrong Classification | ✅ Granules |
3909.50.00.00 |
Primary forms of Amino-resins (If confused with PA) | ❌ Wrong Classification | ✅ Granules |
3916.20.00.00 |
Monofilament ≥ 5mm, Strands, Ophelia of Polyamides | ✅ Fibers/Ropes (Not raw material) | ✅ Fibers |
3917.31.00.00 |
Tubes, Pipes of Polyamides | ✅ Finished Semi-finished goods | ✅ Tubes |
🔍 Key Reminder:
- Most "High Weather-Resistant Polyamide" raw materials are compounded resins. If the product is a compound (PA + UV stabilizer + Carbon Fiber), it may still fall under Chapter 39, but the subheading might shift if it is considered a "Plastic Material in Primary Forms" (3901-3914).
- Standard Nylon 6/66: Use 3902.10.
- Specialty Nylon (e.g., PA4T, PA6T): Use 3904.61.
- Compounded Nylon with Additives: Still generally 3902.10 or 3904.61 if in primary form (granules/powder). Do not classify as "Finished Articles" (Chapter 39.17+).

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance)
✅ 1. Preparation Checklist (No Omissions)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must include: Chemical name (e.g., Nylon 6,6), Molecular weight, Melt Flow Index (MFI), Additives (UV stabilizers, etc.) |
| ✅ Chemical Structure Proof | ✔️ | SDS (Safety Data Sheet) or CAS numbers to prove it is a Polyamide and not another polymer. |
| ✅ Product Photos | ✔️ | Clear view of granules/powder, packaging label showing "Polyamide Resin." |
| ✅ Commercial Invoice | ✔️ | Must specify "Plastic Material in Primary Forms" and "Unmolded." |
| ✅ Certificate of Origin (CO) | ✔️ | If from non-China source, may claim FTZ benefits. |
| ✅ Packing List | ✔️ | Detail gross/net weight, number of bags/pallets. |
✅ 2. Declaration Tips (Key Mantra)
🔥 “Primary Form, Granule/Powder, No Finished Part, Code 3902/3904!”
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Polyamide Granules (Pure or Compounded) | 3902.10.00.00 or 3904.61.00.00 |
Misclassified as "Finished Parts" → 300% penalty |
| Polyamide Pellets with UV Stabilizer | 3902.10.00.00 (if compounded in primary form) |
Split declaration → Each part taxed separately |
| Polyamide Fibers/Ropes | 3916.20.00.00 |
Misclassified as Resin → Wrong tax rate |
| Polyamide Tubes/Pipes | 3917.31.00.00 |
Misclassified as Resin → Wrong tax rate |
📌 Critical Point:
- "Weather Resistant" is a marketing term, not a customs classification term. Do not use it as the HS Code description.
- Declare as: "Nylon 6,6 Polyamide Resin, Granular, Unmolded, with UV Stabilizers."
✅ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Compounds | Provide formulation details if asked. If it’s a blend of two polymers (e.g., PA + PP), it may be classified differently. |
| Recycled Polyamide | If it is recycled, it may still fall under 3902/3904, but must declare as "Recycled Material." Tariffs may still apply. |
| Mixed Containers | If container has both Polyamide and other plastics, declare separately. Never mix different HS Codes in one line item. |
| High-Value Specialty PA | Consider applying for Exclusion under Section 301 if available (check USTR exclusion list). |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification Requirements | Notes |

- USA is the most expensive market for Polyamide raw materials due to combined Section 301 + IEEPA tariffs.
- EU, Japan, Australia offer more favorable rates, but REACH compliance is critical for Europe.
- China remains the production hub, but exporting from China to the US is costly. Consider third-country manufacturing (e.g., Vietnam, Thailand) if possible to avoid US tariffs.
📌 VI. Common Mistakes & Pitfall Guide (Blood-Tear Lessons)
❌ Mistake 1: Classifying Compounded Polyamide (with additives) as a "Finished Part"
👉 Consequence: Wrong HS Code, potential anti-dumping duties, or seizure.
❌ Mistake 2: Using "Weather Resistant" as the Product Name in Customs Declaration
👉 Consequence: Customs may reject or request further clarification, causing delays.
❌ Mistake 3: Not Declaring Additives (UV Stabilizers)
👉 Consequence: If additives change the chemical nature significantly, it might be classified as a different polymer. Be transparent.
❌ Mistake 4: Mixing Polyamide Resin with Other Plastics in One HS Code
👉 Consequence: Each polymer type must be declared separately. Mixing leads to penalties.
✅ Correct Practice:
"Nylon 6,6 Polyamide Resin, Granular, Unmolded, Color: Black, UV Stabilized, CAS 25038-54-4, Model XYZ, Made in China."
🎯 VII. Conclusion: Precision Classification Saves Costs!
🎯 Remember the Mantra:
🔹 "Primary Form = Granules, HS 3902/3904. Finished = Chapter 39.17+. Weather Resistance ≠ New HS Code."
🔹 "US Tariff = 40.3%, Plan Ahead! Avoid Split Declaration, Avoid Mixing Codes!"
📌 Pro Tip:
If your Polyamide Raw Material is originally from Vietnam, Mexico, or Thailand, you may be eligible for IEEPA Exemptions or lower MFN rates.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
