🧪 Polymer Mixture for Injection Molding: The Ultimate HS Code & Tariff Survival Guide (2026 Edition)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Polymer Mixture"?
"Polymer Mixture for Injection Molding" is a broad term in the plastics industry, typically referring to olefin polymers (such as Polyethylene or Polypropylene) prepared in primary forms (granules, powders, flakes) specifically formulated for injection molding processes.
In international trade, the classification hinges on chemical composition and physical form. It is primarily classified under Chapter 39: "Plastics and articles thereof."
⚠️ Key Classification Logic: - If the mixture is predominantly Ethylene (PE) → Chapter 3901 / 3902 - If the mixture is predominantly Propylene (PP) or other olefins → Chapter 3902 - If it is in primary form (granules/powder) → Usually Chapter 3901/3902 - Crucial Distinction: Is it a pure polymer or a mixture? The HS codes below reflect specific mixture scenarios provided in the data.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Mapping)
Based on the provided data, here are the specific HS Codes and their rationales for "Polymer Mixture for Injection Molding":
| HS Code | Product Description & Rationale | Tax Rate Summary | Legal Basis for Classification |
|---|---|---|---|
3902.90.00.50 |
Ethylene Polymer Mixture, Injection Molding Grade Rationale: Classified under Ethylene olefin polymers in primary form, specifically as a mixture suitable for injection molding. |
41.5% | Ethylene-based olefin polymers; Mixture form. |
3902.30.00.00 |
Ethylene Polymer Mixture, Injection Molding Grade Rationale: Specifically categorized under Propylene or other olefin polymers范畴 (category), despite the name implying ethylene, this code covers specific mixed olefin formulations. |
41.5% | Propylene/Other Olefin Polymers; Specific mixture category. |
3901.10.10.00 |
Ethylene Polymer Mixture, Injection Molding Grade Rationale: Classified under Ethylene polymers in primary form (solid granules/powders) intended for further processing. |
41.5% | Ethylene Polymers; Primary Form. |
3901.20.10.00 |
Ethylene Polymer Mixture, Injection Molding Grade Rationale: Ethylene polymer mixture where material properties and primary form attributes align with this specific sub-heading. |
41.5% | Ethylene Polymers; Material consistency with primary form. |
🔍 Important Note: - All listed HS Codes carry the same total tax rate of 41.5%. - The distinction between these codes lies in the chemical specificity (Ethylene vs. Other Olefins) and physical form (Primary vs. Specific Mixture definitions). - Do not mix up "Primary Form" (3901) with "Other Polymers" (3902). Incorrect classification can lead to customs audits or penalties, even if the tax rate is currently the same.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges)
✅ Applicable Country: USA (US)
✅ Origin: China (CN)
✅ Effective Date: Current rates applicable for 2026 imports from China.
🎯 1. Universal Tax Structure for All Listed Codes
| Component | Rate | Description |
|---|---|---|
| Base Duty (MFN) | 6.5% | Standard Most Favored Nation tariff for plastics/polymer mixtures. |
| Section 301 Surcharge | 25.0% | Additional tariff imposed on Chinese imports under Section 301 of the Trade Act. |
| Section 122 Tariff | 10.0% | Additional tariff under Section 122 (likely referring to specific executive orders or trade remedies). |
| TOTAL EFFECTIVE RATE | 41.5% | 6.5% + 25.0% + 10.0% |
📌 Explanation: - The 6.5% is the base statutory duty. - The 25% is the most significant burden, driven by US-China trade tensions (Section 301). - The 10% is an additional layer of protectionism (Section 122). - Result: Importers from China face a 41.5% landed cost increase on the CIF value alone.
🛠️ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Explanation |
|---|---|---|
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Polymer Mixture for Injection Molding" and specify Ethylene vs. Other Olefin content. |
| ✅ Packing List | ✔️ | Detail weight, volume, and packaging type (bags, bulk). |
| ✅ Certificate of Origin (CO) | ✔️ | Critical. Must certify origin as China to apply the correct 41.5% rate. Misdeclaration of origin can lead to higher penalties. |
| ✅ Product Specification Sheet | ✔️ | Must confirm Primary Form (granules/powders) and Chemical Composition (Ethylene/Propylene ratio). |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Required for chemical imports to ensure safe handling and storage. |
✅ 2. Declaration Strategy (Key Tips)
🔥 "Be Specific: Ethylene or Other? Primary Form or Mixed?"
| Scenario | Correct HS Code | Risk if Incorrect |
|---|---|---|
| Pure Ethylene Granules | 3901.10.10.00 or 3901.20.10.00 |
Misclassification as 3902 may trigger scrutiny on chemical composition. |
| Mixed Olefin Granules (Ethylene-based) | 3902.90.00.50 |
If declared as 3901, customs may reject due to "mixture" definition. |
| Mixed Olefin Granules (Propylene-based) | 3902.30.00.00 |
Even if named "Ethylene Mixture," if it fits propylene/other olefin specs, use 3902. |
| Non-Primary Form (e.g., Pre-made Parts) | NOT Covered Here | Would fall under Chapter 39 Articles, not Polymers. Tax rate may differ! |
⚠️ Critical Warning: - Do not use generic terms like "Plastic Granules" in the declaration. - Do specify: "Polyethylene/Polypropylene Mixture, Primary Form, For Injection Molding." - If the product is pre-mixed with additives (colorants, stabilizers), ensure the base polymer is still >50% by weight to remain in Chapter 3901/3902.
✅ 3. Special Circumstances
| Situation | Handling Advice |
|---|---|
| Transshipment via Third Country | High Risk. US Customs will look for "Substantial Transformation." Simple transshipment does NOT avoid the 41.5% rate. |
| Free Trade Agreements (FTA) | No FTA benefits for China-US trade on these HS codes. |
| Dual-Use Items | If the polymer has specific high-tech applications, ensure no export control violations from the origin country. |

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
