🌐 HS Code Reference & Duty Breakdown | U.S. Trade Policy 2026 | Expert-Level Compliance Advice

✅ Product Name: Stretch Film (also known as Pallet Wrap, Stretch Wrap, Plastic Wrap)
✅ Material: Polyethylene (PE) – Thermoplastic resin
✅ Form: Thin, flexible film, typically transparent or translucent, used to secure pallet loads
✅ Primary Use: Packaging, logistics, warehousing, industrial wrapping

📦 I. HS Code Classification Overview (2026 U.S. Harmonized Tariff Schedule)

🔍 Key Classification Principle:
Stretch film is classified based on material (plastic/PE) and form (film, sheet, strip, or tape). It falls under plastic films and sheets, not tapes or adhesives, unless self-adhesive.

Below are the five applicable HS Codes from your data, with detailed explanations for each.

📌 1. 3921.90.50.50 – Other Plastic Films, Sheets, Foil, and Tapes (Non-Adhesive, PE-based)

✅ Classification Justification:
- Not a tape (no backing or adhesive layer)
- Not a rigid sheet or plate
- Purely a flexible, non-adhesive film made from PE
- Matches "Other plastic films" under 3921.90.50

📌 2. 3920.99.20.00 – Other Plastic Flexible Films, Tapes, and Sheets (Non-Adhesive PE)

✅ Classification Justification:
- Not a rigid plastic sheet
- Not a self-adhesive tape
- Falls under "Other" in 3920.99.20
- Matches the flexible film description in 3920.99.20.00

📌 3. 3920.10.00.00 – Plastic Films Made of Ethylene Polymers (e.g., PE)

✅ Classification Justification:
- Stretch film is primarily made from LLDPE (Linear Low-Density Polyethylene), a derivative of ethylene
- This code is specifically designed for films made from ethylene polymers
- More precise than general "other" codes

📌 4. 3919.90.50.60 – Plastic Films, Self-Adhesive or Flat (Non-Adhesive, PE-based)

✅ Classification Justification:
- Stretch film is flat and non-adhesive (unless specially labeled as "self-adhesive stretch film")
- Fits the "flat shape" and "plastic film" criteria
- Not a tape or adhesive product → not eligible for tape-specific codes
- Falls under "other" in 3919.90.50

📌 5. 3919.90.50.40 – Other Plastic Films (Transparent, Non-Adhesive, Derived from PE)

✅ Classification Justification:
- Most stretch films are transparent
- Made from PE, non-adhesive
- Used in packaging applications, often as a derivative of "transparent tape" or film
- Matches the "other" category under 3919.90.50.40

💰 II. 2026 U.S. Tariff Breakdown (China-Origin Products)

📌 Applicable to: All HS Codes above
📌 Origin: China (CN)
📌 Effective Date: November 10, 2025 (as per U.S. Trade Policy Update)
📌 Legal Basis:
- Section 301 (USITC) – 25% additional tariff
- IEEPA (International Emergency Economic Powers Act) – 10% additional tariff

🎯 1. 3921.90.50.50 – Total Duty: 39.8%

- Same附加 taxes → slightly lower total

🎯 3. 3920.10.00.00 – Total Duty: 39.2%

📌 Why This Code is Preferred?
- Most accurate classification for PE-based stretch film
- Matches material (ethylene polymer) and form (film)
- Same duty as 3920.99.20.00, but more precise

🎯 4. 3919.90.50.60 – Total Duty: 40.8%

📌 Why Higher?
- Higher base tariff (5.8%)
- Same附加 taxes → highest total duty among all codes

🎯 5. 3919.90.50.40 – Total Duty: 40.8%

📌 Note:
- Same as 3919.90.50.60 – both have 5.8% base

🌍 IV. Global Tariff Comparison (2026)

📌 Insight:
- U.S. is the only major market imposing 301/IEEPA/122 tariffs on PE stretch film
- Vietnam/Mexico-origin goods can avoid 301/122 duties → consider shifting production

📌 V. Common Mistakes & How to Avoid Them

❌ Mistake 1: Using 3919.90.50.60 or 3919.90.50.40 for standard stretch film
👉 Result: Higher base tariff (5.8%) → extra 1.6% cost → avoid!

❌ Mistake 2: Not specifying material as PE/LLDPE in invoice
👉 Result: Customs may reclassify → higher duty or delay

❌ Mistake 3: Assuming de minimis applies to China-origin goods
👉 Result: Full duty due even on $500 shipment → no exemption

❌ Mistake 4: Labeling as "tape" or "adhesive wrap"
👉 Result: May trigger incorrect classification → higher duty or seizure

✅ Best Practice:

Use exact language:
"Stretch Film, Polyethylene (PE), Non-Adhesive, 100% LLDPE, 12 Microns, 12" Width, 1000 ft Roll"

🎯 VI. Final Verdict: Smart Strategy for Success

✅ Recommended HS Code: 3920.10.00.00
✅ Why?
- Most accurate for ethylene-based PE films
- Lowest total duty (39.2%)
- Matches material and form perfectly
- Avoids higher base rates

❌ Avoid: 3919.90.50.60 and 3919.90.50.40 unless specifically transparent or tape-like

🚀 Pro Tip:
If exporting from Vietnam, Mexico, or Thailand, apply for Certificate of Origin → eliminate 301/122 duties → 0% tariff!
