🧪 Polybutene Copolymer Resin (Industrial Chemicals & Polymers)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategies
📌 I. Product Definition & Classification: Understanding "Polybutene Copolymer Resin"
Polybutene Copolymer Resin is a synthetic polymer primarily composed of butene monomers, often copolymerized to enhance specific mechanical or chemical properties. In international trade, it is classified based on its chemical composition and physical state. The key distinction lies between: 1. Basic Forms (Primary Forms): Raw resins, granules, powders, or liquids intended for further processing (extrusion, molding, compounding). 2. Finished Goods: Items shaped into specific final products (tubes, sheets, containers) unless specifically exempted.
⚠️ Critical Distinction Point:
- If the material is "Polyethylene Copolymer" or "Polypropylene Copolymer" (despite the name "Polybutene," trade names can be misleading), it may fall under Chapter 39 subheadings for PE or PP.
- If it is a true Polybutene or other unspecific plastic in primary form, it typically falls under 3901.90 or 3902.90 depending on the dominant monomer.
- If it is a finished article (e.g., seals, gaskets, molded parts) not identifiable as a specific raw material, it may fall under 3926.90.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
Based on the provided data, here are the precise HS Codes, summaries, and tax implications for "Polybutene Copolymer Resin" depending on its exact chemical composition and form:
| HS Code | Product Description | Application Scenario | Key Classification Criteria |
|---|---|---|---|
3901.40.00.00 |
Polyethylene Copolymers in Primary Forms | Raw PE copolymer resins (e.g., LLDPE, MDPE) used for film extrusion, blow molding. | Matches "Polyethylene Copolymer" material. Note: If the product is actually PE, use this. |
3901.90.55.01 |
Other Polyethylene, Primary Forms | Specific sub-category for PE copolymers not elsewhere specified. | Explicitly identifies "Polyethylene Copolymer" in name. |
3902.30.00.00 |
Polypropylene Copolymers | Raw PP copolymer resins (e.g., impact copolymers) for injection molding. | Matches "Polypropylene Copolymer" material. Note: If the product is actually PP, use this. |
3902.10.00.00 |
Polypropylene, Primary Forms | Homopolymer PP resins. | Matches "Polypropylene" material. |
3926.90.99.89 |
Other Articles of Plastics | Finished plastic articles not specified elsewhere (e.g., molded parts, seals). | Matches "Polypropylene" as a final article. Used if the resin is already processed into a non-primary form. |
🔍 Key Warning:
- "Polybutene" vs. "Polyethylene/Polypropylene": Many suppliers use generic names. If the SDS (Safety Data Sheet) confirms the monomer is Ethylene, use 3901.xxxx. If it is Propylene, use 3902.xxxx. If it is truly Butene (Polybutene), it often falls under 3901.90 or 3906.90 (if acrylate-based) or 3902.90.
- The provided data shows strong matches for PE and PP Copolymers. If your "Polybutene" is chemically a PE/PP copolymer, use the corresponding 3901/3902 code.
- If it is a finished plastic part, use 3926.90.99.89.

| ✅ Commercial Invoice | ✔️ | Clearly state "Polybutene Copolymer Resin" OR "Polyethylene Copolymer" if chemically different. |
| ✅ Packing List | ✔️ | Detail net/gross weight, container type. |
| ✅ Certificate of Origin | ✔️ | Required for Section 301 duty determination. |
✅ 2. Declaration Tips (Critical Keywords)
🔥 "Know Your Monomer, Save Your Duty! Resin vs. Part Matters!"
| Scenario | Correct Declaration | Wrong Declaration | Consequence |
|---|---|---|---|
| Raw Resin (PE Copolymer) | "Polyethylene Copolymer Resin, Granular, Primary Form" | "Plastic Pellets" (Vague) | Risk of 41.5% + Penalties for misclassification |
| Raw Resin (PP Copolymer) | "Polypropylene Copolymer Resin, Granular, Primary Form" | "Polybutene" (If incorrect) | Risk of 41.5% + Penalties if chemically PP |
| Finished Plastic Part | "Plastic Seal/Gasket, Polypropylene Based, Finished Article" | "Resin" (Incorrect Form) | Savings! 22.8% instead of 41.5% |
| True Polybutene | "Polybutene Resin, Primary Form" | Misidentified as PE/PP | May require separate classification (often 3901.90 or 3906.90), check specific tariff schedule. |
⚠️ Important: If the product is truly Polybutene (not PE or PP), and not listed in the provided data, it typically falls under 3901.90 (Other Ethylene Polymers) or 3906.90 (Acrylic Polymers) or 3902.90 (Other Olefin Polymers). However, based on the provided data, the system strongly links "Polybutene Copolymer" to PE/PP classifications due to naming overlaps. Verify with SDS!
✅ 3. Special Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Resin | Provide client order + technical spec sheet to prove identity. |
| Mixed Shipment (Resin + Parts) | Declare separately. Resin under 3901/3902, Parts under 3926. |
| Chinese Origin | Expect 301 + 122 surcharges. Budget for high duties. |
| Non-Chinese Origin (e.g., Vietnam, Korea) | Apply for Section 301 Exclusion if available, or lower base rates. |

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
