🧱 Non-Foamed Polyamide Plastic Sheet
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Plastic Sheets"?
Non-foamed Polyamide Plastic Sheet refers to flat, rigid, or semi-rigid sheets made from polyamide (commonly known as Nylon) that are not cellular (i.e., they are solid, not foamed/aerated). In international trade, these products are typically classified under Chapter 39 (Plastics and Articles Thereof). The critical distinction lies in whether the product is cellular (foamed) or non-cellular (solid).
⚠️ Key Distinction:
- If the plastic is cellular/foamed → Classified under 3921.19 (Cellular plastics)
- If the plastic is non-cellular/solid (like your product) → Classified under 3921.90 (Other plastics, not cellular)
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Cellular? |
|---|---|---|---|
3921.90.50.50 |
Other plates, sheets, film, foil and strip, of plastics: Other: Other | Solid/Non-foamed Polyamide Sheets, Nylon sheets, rigid plastic plates | ❌ No (Solid) |
3921.19.00.90 |
Other plates, sheets, film, foil and strip, of plastics: Cellular: Of other plastics Other | Foamed Nylon sheets, Expanded Polyamide panels, lightweight insulating plastic boards | ✅ Yes (Foamed) |
🔍 Critical Reminder:
- Your product is Non-foamed (solid), so it MUST NOT be classified under3921.19.00.90even if the chemical composition (Polyamide) is similar.
- The classification depends on the physical structure (cellular vs. non-cellular), not just the material type.
💰 III. 2026 Latest Tariff Rate Details (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025 November 10 onwards (for subsequent imports)
🎯 1. 3921.90.50.50 —— Solid Non-Cellular Polyamide Sheets
| Item | Content |
|---|---|
| Base Tariff Rate | 4.8% (ad valorem) |
| Section 301 Surtax (USITC) | +25.0% (Applied to Chinese-origin plastics under specific subheadings) |
| IEEPA Surtax | 0.0% (Not applicable for this specific HS code under current IEEPA directives) |
| Total Tax Rate | 29.8% |
| Tax Calculation | CIF Value × 29.8% |
| De Minimis Eligibility | ❌ Not Eligible (deny_de_minimis) |
| Legal Basis Path | USITC:3921.90.50.50 → FOOTNOTE:301.88.01 (if applicable) |
📌 Explanation:
- The 4.8% is the standard MFN (Most Favored Nation) duty for other plastic plates/sheets.
- The 25.0% is the "Section 301" additional duty imposed by the US Trade Representative on certain Chinese goods.
- Total: 29.8%. This is a significant cost factor that must be calculated into your landed cost.
🎯 2. 3921.19.00.90 —— Cellular (Foamed) Polyamide Sheets
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% |
| Section 301 Surtax (USITC) | 0.0% |
| IEEPA Surtax | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Calculation | CIF Value × 0.0% |
| De Minimis Eligibility | ✅ Eligible (may qualify for de minimis if value < $800) |
| Legal Basis Path | USITC:3921.19.00.90 |
📌 Note:
- While this code has 0% tax, it does not apply to your product because it is non-foamed.
- Misclassifying a solid sheet as cellular foam to avoid tariffs is a high-risk customs violation and can lead to severe penalties, seizure, and blacklisting.
🛠️ IV. Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documentation List (No Exceptions)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must explicitly state: "Non-foamed", "Solid", Material: Polyamide (Nylon), Thickness, Dimensions. |
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Confirms chemical composition and physical properties. |
| ✅ Product Photos | ✔️ | Clear images showing the solid cross-section (no pores/bubbles) to prove it is not foamed. |
| ✅ Commercial Invoice | ✔️ | Description must match HS Code: "Non-foamed Polyamide Plastic Sheet". |
| ✅ Packing List | ✔️ | Details net/gross weight, packaging type. |
| ✅ Certificate of Origin (CO) | ✔️ | To prove Chinese origin (triggers the 25% surtax). |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Solid means 29.8%, Foam means 0%, But False Decl = Huge Penalties!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Solid Nylon Sheet | 3921.90.50.50 |
Misdeclare as 3921.19.00.90 to save tax → Audit Risk + Penalties |
| Foamed Nylon Board | 3921.19.00.90 |
Over-declare as solid → Unnecessary 29.8% Tax |
| Mixed Shipment | Split Declaration | Combine into one line item → Confusion & Delay |
📌 Actionable Advice:
- Include a "Structure Declaration" in your commercial invoice: "Item is non-cellular, solid polymer sheet, not foamed or expanded."
- Provide cross-section photos if requested by CBP (Customs and Border Protection).
✅ 3. Special Cases & Handling
| Scenario | Handling Advice |
|---|---|
| Polyamide Blend | If the sheet is 100% Polyamide, use 3921.90.50.50. If mixed with other plastics, still generally 3921.90.xxxxxx unless primary use changes classification. |
| Reinforced Nylon | If fiberglass-reinforced, still likely 3921.90 unless it meets the definition of a "composite article" elsewhere. Consult a broker. |
| Thin Film vs. Sheet | If thickness < 1mm, it might be considered "film" (3920.xxxx). Clarify thickness in specs. |
🌍 V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification | Note |
|---|---|---|---|---|
| 🇺🇸 USA | 3921.90.50.50 |
29.8% (4.8% base + 25% surtax) | None Specific | High tariff due to Section 301. |
| 🇨🇳 China | 3921.90.90.00 |
~5-10% (varies) | None | Domestic trade applies. |
| 🇪🇺 EU | 3921.90.99 |
~0-6.5% | REACH Compliance | No Section 301 equivalent. |
| 🇬🇧 UK | 3921.90.90 |
~0-6.5% | UK REACH | Post-Brexit rules apply. |
| 🇯🇵 Japan | 3921.90.00 |
~0-5% | None | Low tariff environment. |
📌 Conclusion:
- USA is the most expensive market due to 25% Section 301 surtax.
- If targeting the US market, optimize logistics and landed cost to absorb the 29.8% total duty.
- Consider third-country assembly (if rules of origin allow) to mitigate surtax, but this is complex for plastic sheets.
📌 VI. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Claiming "Polyamide Sheet" is automatically 0% tariff
👉 Consequence: CBP rejects declaration, demands 29.8% + penalties.
❌ Mistake 2: Using "Foamed" in description for solid sheets to get 0% tax
👉 Consequence: Customs inspection finds solid structure → Fraud Penalty + Seizure.
❌ Mistake 3: Ignoring thickness definition
👉 Consequence: If too thin, it might be "film" (3920), which has different duty rates. Clarify thickness!
✅ Correct Declaration Example:
"NON-FOAMED POLYAMIDE (NYLON) PLASTIC SHEET, SOLID STRUCTURE, THICKNESS: 3MM, SIZE: 1200x2400MM, FOR INDUSTRIAL USE"
🎯 VII. Conclusion: Precision Classification Saves Money & Prevents Risks!
🎯 Remember the Mantra:
🔹 "Solid Nylon = 29.8% (US), Foamed Nylon = 0% (US), But Fake Decl = Disaster!"
🔹 "Check Structure, Not Just Material! Thickness Matters Too!"
📌 Pro Tip:
If your polyamide sheets are thin (<1mm), check if they qualify as "film" (3920.xxxx), which may have different duty rates.
Always provide cross-section photos and material specs to CBP to avoid delays.
📣 Immediate Action:
📞 Engage a licensed customs broker for pre-classification ruling if unsure.
🚀 Calculate Landed Cost including 29.8% US tariff to ensure profitability.
✨ Professional Clearance Starts with Accurate Classification!
💼 Your Bottom Line Depends on Every Digit!

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
