🧪 C6-C8 Olefin Copolymer Polyethylene

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy 📌 1. Product Definition & Classification: What Exactly is "C6 C8 Olefin Copolymer Polyethylene"?

C6-C8 Olefin Copolymer Polyethylene refers to a specific type of ethylene-alpha-olefin copolymer where the co-monomer consists of alpha-olefins with carbon chains of 6 to 8 atoms (such as 1-hexene or 1-octene). Unlike standard High-Density Polyethylene (HDPE), these copolymers are engineered to have a specific gravity of less than 0.94, making them part of the Low-Density Polyethylene (LDPE) or Linear Low-Density Polyethylene (LLDPE) family.

In international trade, the critical distinction lies in the Specific Gravity (< 0.94) and the Primary Form (resins/granules vs. finished articles).

⚠️ Key Classification Point: - If the product is in primary forms (pellets, powders, liquids) and has a specific gravity < 0.94 →归入 3901.40.00.00. - If it is in primary forms but has a specific gravity ≥ 0.94 (HDPE) →归入 3901.10.00.00 (Not in data, but general rule). - If it is a finished article (bags, films) →归入 Chapter 39, Part IV (e.g., 3923.21 or 3920.10).

📦 2. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)

Based strictly on the provided , here are the applicable HS Codes for C6-C8 Olefin Copolymers, categorized by form and usage.

🔍 Critical Distinction: - Raw Material (Resin): If you are importing the pellets/resin used to make the films or bags, use 3901.40.00.00. Tax is 0%. - Finished Film: If you are importing pre-made films/sheets, use 3920.10.00.00. Tax is 29.2%. - Finished Bags: If you are importing pre-made bags, use 3923.21.00.85 or 3923.21.00.95. Tax is 28.0%.

⚠️ Note on "C6 C8": This specific chemical composition usually falls under 3901.40.00.00 because C6-C8 copolymers are the standard definition of LLDPE with density < 0.94. Do not misclassify raw resin as a "film" or "bag" to avoid unnecessary tariffs if you are manufacturing downstream.

💰 3. 2026 Latest Tariff Rate Detail (Including Additional Taxes & Policies)

✅ Applicable Country: United States (US) ✅ Origin: China (CN) ✅ Effective Date: 2025/2026 Tariff Periods

🎯 1. 3901.40.00.00 —— Ethylene-Alpha-Olefin Copolymers (Specific Gravity < 0.94)

📌 Explanation: - This is a duty-free entry for primary forms of C6-C8 copolymer resins. - No Section 301 tariffs apply to this specific subheading. - Advantage: Maximum cost efficiency for raw material importers.

🎯 2. 3920.10.00.00 —— Non-Cellular Ethylene Films/Sheets

📌 Explanation: - Importing pre-made films triggers the 25% Section 301 penalty. - Cost Impact: Significantly higher than importing raw resin. - Strategy: If possible, import resin (3901.40.00.00) and manufacture films domestically to save ~29%.

🎯 3. 3923.21.00.85 / 3923.21.00.95 —— Polyethylene Bags

📌 Explanation: - Retail carrier bags (with handles) are classified under 3923.21.00.85. - Industrial sacks/non-retail bags fall under 3923.21.00.95. - Both incur the 25% punitive tariff.

🛠️ 4. Custom Clearance Practical Advice (Battle-Tested Pitfall Avoidance)

✅ 1. Preparation Checklist (Essential Documents)

💡 Tip: For raw resin, ensure the invoice description matches HS 3901.40.00.00 exactly. Avoid vague terms like "Plastic Pellets."

✅ 2. Declaration Strategy (Key Mantras)

🔥 “Raw Resin is Free, Films & Bags are Taxed! Know Your Form!”

⚠️ Warning: - Do not declare "Film" when importing "Resin." - Do not declare "Resin" when importing "Film." - Specific Gravity is the key parameter. If SG ≥ 0.94, it is not 3901.40.00.00. It may be 3901.10.00.00 (HDPE) or 3901.90.55.01, which may have different tariff treatments (check latest HTSUS for HDPE tariffs, though data provided only shows 3901.40 as 0%).

✅ 3. Special Cases & Handling

🌍 5. Global Market Comparison (2026 Overview)

📌 Conclusion: - USA is the most tax-sensitive market for C6-C8 Polyethylene products due to Section 301 tariffs on finished films and bags. - Raw Resin Import remains duty-free (0%) in the US, making it the most cost-effective strategy for manufacturers.

📌 6. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring Film as Resin to avoid 29.2% tax. 👉 Consequence: Customs inspection, seizure, fines, and blacklisting.

❌ Mistake 2: Ignoring Specific Gravity. 👉 Consequence: If SG ≥ 0.94, the product is not 3901.40.00.00. Misclassification leads to back taxes and penalties.

❌ Mistake 3: Confusing Retail Bags (3923.21.00.85) with Industrial Sacks (3923.21.00.95). 👉 Consequence: Both are 28%, but incorrect description slows customs clearance and triggers unnecessary queries.

❌ Mistake 4: Assuming All Ethylene Copolymers are 0%. 👉 Consequence: Only those with SG < 0.94 (3901.40) are 0% in the provided data. Others may be taxable.

✅ Correct Practice:

"Ethylene-Alpha-Olefin Copolymer Resin (LLDPE), C6-C8, Specific Gravity 0.92, Primary Form, Pellets, Model XYZ, MSDS Provided"

🎯 7. Conclusion: Precision in Classification, Profit in Compliance!

🎯 Remember the Mantra:

🔹 “Resin is Free, Film is Taxed! Specific Gravity is King!” 🔹 “C6-C8 < 0.94 = 0% Duty! Above 0.94 = Check Other Codes!” 🔹 “Don’t Hide Finished Goods in Raw Materials – Customs Knows!”

📌 Pro Tip:

If you are importing C6-C8 Copolymer Resin for manufacturing in the US, ensure you have ISF (Importer Security Filing) filed 24 hours before loading. For finished films/bags, consider tariff engineering: Can you import resin and film locally to save 29%? Yes!

📣 Immediate Action:

📞 Contact a licensed customs broker. 📄 Provide Product Spec Sheets with Specific Gravity. 🚀 Clearance Strategy: Import Raw Resin (3901.40.00.00) for 0% duty. Import Finished Films/Bags only if necessary, and budget for 28-29% tax.

✨ Professional Customs Clearance Starts with Accurate Classification! 💼 Your Margin Depends on the HS Code!
