🧪 Low Density Polyethylene for Cables (LDPE)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 1. Product Definition & Classification: Do You Really Understand "LDPE for Cables"?
Low-Density Polyethylene (LDPE) is a thermoplastic manufactured mostly from the monomer ethylene. In the context of cables, it serves as a critical insulation and sheathing material due to its excellent electrical insulation properties, flexibility, and moisture resistance.
In international trade, LDPE is generally classified under Chapter 39 (Plastics and Articles Thereof). However, the specific HS code depends on whether the material is in its raw form (resin/beads) or processed form (compounds/pre-molded parts) and its specific application for electrical purposes.
⚠️ Key Distinction Point:
- If the product is raw resin/beads/powder intended for manufacturing insulation → Classify under 3901.10 or 3901.20.
- If the product is a compound (e.g., with additives for UV resistance or flame retardancy specifically for cables) → Classify under 3901.90 or 3902.10 depending on polymer type.
- Note: Finished cable assemblies are excluded here; this guide covers only the polyethylene material.
📦 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Form of Material |
|---|---|---|---|
3901.10.00 |
Polyethylene, Linear, Density < 0.94 | Linear LDPE (LLDPE) for thin cable films | ✅ Raw Resin/Beads |
3901.20.00 |
Polyethylene, Non-Linear, Density < 0.94 | Standard LDPE for cable insulation & sheathing | ✅ Raw Resin/Beads |
3901.90.00 |
Polyethylene in primary forms (Other) | Specialized LDPE compounds, recycled LDPE pellets | ✅ Raw Resin/Pellets |
3902.10.00 |
Polypropylene in primary forms | Incorrect for LDPE, often confused due to similar usage | ❌ N/A |
3907.60.00 |
Polyacetals (POM) | Incorrect, POM is a different plastic used in connectors, not insulation | ❌ N/A |
3926.90.97 |
Other articles of plastics | Incorrect, applies to finished plastic parts, not raw material for cables | ❌ N/A |
🔍 Important Reminder:
- Most standard LDPE for cable insulation falls under3901.20.00(Non-linear, density < 0.94).
- If the LDPE is compounded with additives (e.g., carbon black for UV protection, flame retardants), it may still fall under 3901/3902 if it retains its base polymer identity, or 3901.90 if it’s a specialized mixture.
- Do not classify as finished goods (e.g., wire & cable) under Chapter 85.
💰 3. 2026 Latest Tariff Rate Details (Including Surtaxes, Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)

🛠️ 4. Customs Clearance Practical Advice (Field Pitfall Avoidance Guide)
✅ 1. Preparation of Documentation (Must-Haves)
| Document | Required | Description |
|---|---|---|
| ✅ Material Safety Data Sheet (MSDS) | ✔️ | Essential for chemical products, shows composition |
| ✅ Technical Data Sheet (TDS) | ✔️ | Specifies density, melt index, intended use (e.g., "for cable insulation") |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Low Density Polyethylene, Primary Form" |
| ✅ Certificate of Origin (CO) | ✔️ | If claiming preferential rates (e.g., under USMCA for Canadian/Mexican origin) |
| ✅ Bill of Lading | ✔️ | Standard shipping document |
| ✅ Plastic Waste Regulations Compliance | ✔️ | If using recycled LDPE, additional EPA/EU compliance docs may be needed |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Raw Resin, Not Wire, Density Key, Chapter 39!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| LDPE Beads/Pellets for Cable Insulation | 3901.20.00 |
Misclassify as "Plastic Parts" → Higher duty |
| LDPE Sheeting/Sheathing (Pre-formed) | 3921.10.00 |
Misclassify as raw material |
| Finished Cable (with Copper Core) | 8544.42.00 |
Misclassify LDPE resin as finished cable |
| Recycled LDPE Pellets | 3901.90.00 |
Claiming virgin material status → Fraud risk |
✅ 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Compounded LDPE (with Additives) | If additives change the essential character, it may still be 3901/3902. Provide formulation details. |
| Recycled LDPE | Subject to stricter EPA regulations. Ensure it meets US recycling standards. |
| FDA-Approved LDPE | If used for food-contact cable coatings (rare but possible), provide FDA compliance docs. |
| Flame-Retardant LDPE | Check for additional safety certifications (UL, VDE) for customs inspection. |
🌍 5. Global Main Markets Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification Requirements | Notes |
|---|---|---|---|---|
| 🇺🇸 United States | 3901.20.00 |
5.3% | None specific | Base duty applies |
| 🇨🇳 China | 3901.20.00 |

| 🇯🇵 Japan | 3901.20.00 |
5.0% | JIS Standards | Low duty, high quality standards |
📌 Conclusion:
- LDPE is a low-duty raw material globally, but compliance with chemical regulations (REACH, EPA) is critical.
- US Base Duty: 5.3%, which is significantly lower than finished plastic products.
- China Origin: No additional Section 301 tariffs on base polyethylene, but verify specific sub-headings.
📌 6. Common Errors & Pitfall Guide (Blood Lessons)
❌ Error 1: Declaring LDPE as "Plastic Parts" (3926)
👉 Consequence: Higher duty (e.g., 3-5% vs 5.3%, but potential misclassification penalties) and inspection delays.
❌ Error 2: Failing to distinguish between Raw Resin and Finished Cable
👉 Consequence: Classifying raw LDPE as finished cable (8544) → Duty may be different, and regulatory requirements (FCC, UL) are irrelevant for raw material, leading to confusion.
❌ Error 3: Ignoring Recycled Content Regulations
👉 Consequence: If using recycled LDPE, failure to provide EPA compliance docs → Shipment held or destroyed.
❌ Error 4: Incorrect Density Declaration
👉 Consequence: LDPE density < 0.94 goes to 3901.20; if density is ≥ 0.94, it may go to 3901.40 (HDPE). Misclassification → Duty rate change + penalty.
✅ Correct Practice:
"Low Density Polyethylene (LDPE), Resin, Non-Linear, Density 0.92 g/cm³, Melt Index 2.0 g/10min, For Cable Insulation Application, UN3082 (if applicable), HS 3901.20.00"
🎯 7. Conclusion: Professional Declaration, Cost-Saving & Efficiency!
🎯 Remember the Mnemonic:
🔹 "Raw Resin, Chapter 39, Density Key, 5.3% Base!"
🔹 "Don't confuse with finished cable, Chapter 85 is for wire!"
🔹 "Recycled LDPE? Check EPA, otherwise stuck!"
📌 Tip:
If your LDPE is originating from Canada or Mexico, you can apply for USMCA Preferential Tariff, reducing duty to 0%.
Recommend pre-classification ruling if the product is a specialized compound, to avoid customs disputes.

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
