🧊 Polyethylene Polymer Plastic Stretch Film (PE Stretch Wrap)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "PE Stretch Film"?

Polyethylene (PE) Stretch Film is a highly flexible, transparent plastic material used primarily for unitizing palletized goods, protecting surfaces, and packaging. In international trade, its classification depends heavily on material composition (specifically the polymer type) and physical form (film vs. granules).

Key Distinction Points: * Primary Form (Granules/Pellets): If the PE is in raw, unformed state → Classified under Chapter 3902. * Finished Form (Film/Sheets): If the PE is extruded into thin sheets/films → Classified under Chapter 3920 or 3921. * "Other" Category: If the specific PE type doesn't fit standard "Polyethylene" subheadings, it may fall under "Other Plastics."

⚠️ Critical Clarification:
- "Polyethylene" (PE) is chemically distinct from "Polypropylene" (PP). Misidentifying the resin type leads to incorrect HS codes.
- "Stretch Film" is a functional description, not a customs classification term. Customs classifies based on material + form, not function.
- Granules vs. Film: Raw PE pellets are taxed differently than finished stretch rolls. Do not mix these in one shipment declaration.

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

Based on the provided data, here are the 5 most relevant HS Codes for Polyethylene/Plastic Films, along with their logical fit and tax implications.

🔍 Priority Recommendation:
- If you are importing finished stretch film rolls: Use 3921.90.40.90 or 3921.90.50.50.
- If you are importing PE granules to manufacture film: Use 3902.10.00.00.
- Avoid 3920.20.00.55 and 3902.30.00.00 unless you are sure the material is Polypropylene (PP) and not Polyethylene (PE).

💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Duties)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 onwards

🎯 1. 3921.90.40.90 – Other Plastics, Film (PE Stretch Film)

📌 Explanation:
- The 4.2% base rate applies to "Other plastics, in plates, sheets, film."
- The 25% Section 301 duty is standard for most Chinese plastics.
- The 10% Section 122 duty may apply specifically to plastic films depending on the exact classification and current trade enforcement.
- Total: 39.2% – This is a high-cost item for importers.

🎯 2. 3921.90.50.50 – Other Plastics, Film (Alternative Subheading)

📌 Note:
- Slightly higher base rate (4.8%) compared to 3921.90.40.90.
- Use this if your specific PE film product is classified under this more specific "other" subheading.

🎯 3. 3902.10.00.00 – Polyethylene, Primary Forms (Granules)

📌 Explanation:
- This is for RAW MATERIAL (PE pellets), NOT finished film.
- Higher base rate (6.5%) because raw polymers are taxed differently than finished films.
- Only use if you are importing bulk resin.

🎯 4. 3902.30.00.00 – Polymers of Propylene, Primary Forms

⚠️ WARNING:
- This code is for Polypropylene (PP) granules, NOT Polyethylene (PE).
- Do NOT use for PE stretch film.

🎯 5. 3920.20.00.55 – Polypropylene (PP) Film

⚠️ WARNING:
- This code is for Polypropylene (PP) Film, NOT Polyethylene (PE).
- Common mistake: Stretch film is often PE, but sometimes PP. Verify your Material Safety Data Sheet (MSDS) or Product Specification. If it is PE, do not use this code.

🌍 V. Global Market Comparison (2026)

📌 Conclusion:
- USA is the highest-cost market for PE stretch film due to Section 301 and 122 duties.
- Plan pricing accordingly. Consider supply chain diversification if volume is high.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Classifying PE Film as PP Film (3920.20.00.55)
👉 Result: If audited, you owe the difference in tax + penalties. PE and PP are chemically different.
✅ Fix: Always confirm resin type with MSDS.

❌ Mistake 2: Classifying PE Granules as Film (3921.90.40.90)
👉 Result: Wrong tax rate (4.2% vs 6.5% base). CBP may assess higher duties or penalize.
✅ Fix: Declare form correctly: "Granules" vs. "Film."

❌ Mistake 3: Ignoring Section 122 Duties
👉 Result: Underpaying by 10%.
✅ Fix: Always check if Section 122 applies to your specific plastic film subheading.

❌ Mistake 4: Vague Description "Plastic Wrap"
👉 Result: CBP Request for Info (RFI), shipment delay.
✅ Fix: Use "Polyethylene (PE) Stretch Film, 23 microns, 12 inches wide, 1000 ft roll."

🎯 VII. Conclusion: Precision in Classification Saves Money

🎯 Key Takeaway:

🔹 "PE is not PP. Film is not Granules. Code dictates cost."
🔹 USA Tariff for PE Stretch Film: ~39.2%. Plan your margin accordingly.
🔹 Always verify material type before declaring.

📌 Pro Tip:
If your PE stretch film is imported from Vietnam, Mexico, or Thailand, you may avoid Section 301 duties. Check USMCA or FTAs for potential 0%~5% rates.
Get an Advance Ruling from CBP if you are unsure about the classification of your specific PE film product.
