🧬 Polyamide Stretch Film (Nylon Stretch Film)

🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Polyamide Film"?

Polyamide (PA) stretch film, commonly known as Nylon Film, is a high-performance plastic film characterized by high tensile strength, excellent abrasion resistance, and good oxygen barrier properties. In international trade, it is primarily classified based on its state of aggregation and processing stage:

1. Finished Plastic Film (Chapter 39, Heading 3920):
   Plates, sheets, or films of plastics, not reinforced, laminated, supported, or similarly combined with other materials. This is the most common classification for standard polyamide stretch films used for packaging, labeling, or insulation.
2. Primary Forms (Chapter 39, Heading 3908):
   Polyamides in primary forms (e.g., granules, powder, non-film sheets for further processing). If the "film" is actually a raw material sheet intended for cutting or re-extrusion into other forms, it may fall here.
3. Textile Products (Chapter 54):
   If the polyamide product is woven, knitted, or non-woven fabric, it may be classified under Chapter 54. However, "film" typically implies a continuous, non-fabric structure, making this less likely unless it's a specific "film-coated fabric."

⚠️ Key Distinction Point:
- If it is a continuous, single-layer or multi-layer plastic film (even if stretched/biaxially oriented) → Heading 3920.
- If it is raw polyamide material in sheet form for further manufacturing → Heading 3908.
- If it is woven nylon fabric → Heading 5407.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority对照)

🔍 Key Reminder:
- "Film" (薄膜) vs. "Primary Form" (初级形态): The key is the intended use. If it is ready for packaging or lamination, it is 3920. If it is raw material for making other products, it is 3908.
- Do not confuse with Textiles: If it is a solid, continuous sheet (even if flexible), it is 3920. If it is a fabric weave, it is 5407.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes & Policy Add-ons)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)

🎯 1. 3920.99.10.00 —— Polyamide Film (Finished Film)

📌 Explanation:
- The 25% is the Section 301 tariff, heavily impacting Chinese-manufactured plastic films.
- The 10% is the new IEEPA add-on, increasing the total burden significantly.
- Total 41% is a very high tariff, requiring strict cost control and accurate classification.

🎯 2. 3908.10.00.00 —— Polyamides in Primary Forms

📌 Note:
- Slightly higher base rate than 3920.99.10.00, but the total tax impact is nearly identical.
- Use this code only if the product is clearly a raw material (e.g., large rolls for re-processing), not a finished film for packaging.

🎯 3. 3908.90.70.00 —— Other Polyamides in Primary Forms

📌 Note:
- This is a catch-all for primary forms not specified in 3908.10.
- Highest base rate among the primary forms, but still subject to the same surtaxes.

🎯 4. 3920.92.00.00 —— Other Polyamide Films

📌 Note:
- Lowest total tariff among the polyamide film codes (39.2%).
- Caution: This code may require specific documentation to prove it falls under "other" polyamide films and not the more specific 3920.99.10.00. Misclassification can lead to penalties.

🎯 5. 5407.41.00.30 —— Woven Nylon Fabric (Inferred)

📌 Warning:
- Highest total tariff (48.6%).
- Only applicable if the product is woven fabric. If you ship it as "film" but it is classified as fabric, you will face high taxes and potential penalties for misdeclaration.

✅ 1. Preparation Checklist (Essential Documents)

✅ 2. Declaration Tips (Key Mnemonics)

🔥 "Film is Film, Fabric is Fabric, Primary Form is Raw! Don't Mix Them Up!"

✅ 3. Special Cases Handling

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- USA is the most challenging market due to Section 301 + IEEPA surtaxes.
- Other markets have much lower tariffs (5-7%), making them more cost-effective if diversification is possible.

📌 VI. Common Errors & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring "Nylon Film" as "Textile" (5407) to avoid surtaxes
👉 Consequence: If customs determines it is a film, you face penalties for undervaluation and back-taxes.

❌ Mistake 2: Declaring "Raw Material Sheets" as "Finished Film"
👉 Consequence: Higher tariff (41.3% vs. 39.2%) and potential seizure if not aligned with use.

❌ Mistake 3: Ignoring IEEPA 10% Add-on
👉 Consequence: Underpayment of taxes. Effective from Nov 10, 2025, this is mandatory.

✅ Correct Approach:

"Polyamide (Nylon) Stretch Film, Single-Layer, Biaxially Oriented, for Packaging Use, Model XYZ, Thickness 0.05mm, Width 1000mm"

🎯 VII. Conclusion: Precision in Classification Saves Costs!

🎯 Remember the Mnemonic:

🔹 "Film is 3920, Primary is 3908, Fabric is 5407!"
🔹 "USA Tariff: Base + 25% + 10% = Total 41%+!"
🔹 "Misclassification = Penalty + Delay + High Tax!"

📌 Pro Tip:
If your Polyamide Film is originally produced in Vietnam, Mexico, Thailand, or Malaysia, you may avoid the IEEPA 10% surtax.
Recommendation: Apply for an Advance Ruling before shipment to ensure correct HS Code classification and avoid customs delays.
