π§ͺ Polymer Mixture for Injection Molding: The Ultimate HS Code & Tariff Survival Guide (2026 Edition)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Strategy
π 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."
β οΈ Key Classification Logic: - If the mixture is predominantly Ethylene (PE) β Chapter 3901 / 3902 - If the mixture is predominantly Propylene (PP) or other olefins β Chapter 3902 - If it is in primary form (granules/powder) β 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.
π¦ 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 polymersθη΄ (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. |
π 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.
π° III. 2026 Latest Tariff Rate Breakdown (Including Surcharges)
β Applicable Country: USA (US)
β Origin: China (CN)
β Effective Date: Current rates applicable for 2026 imports from China.
π― 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% |
π 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.
π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (Non-Negotiable)
| Document | Mandatory? | Explanation |
|---|---|---|
| β Commercial Invoice | βοΈ | Must clearly state: "Polymer Mixture for Injection Molding" and specify Ethylene vs. Other Olefin content. |
| β Packing List | βοΈ | Detail weight, volume, and packaging type (bags, bulk). |
| β Certificate of Origin (CO) | βοΈ | Critical. Must certify origin as China to apply the correct 41.5% rate. Misdeclaration of origin can lead to higher penalties. |
| β Product Specification Sheet | βοΈ | Must confirm Primary Form (granules/powders) and Chemical Composition (Ethylene/Propylene ratio). |
| β MSDS (Material Safety Data Sheet) | βοΈ | Required for chemical imports to ensure safe handling and storage. |
β 2. Declaration Strategy (Key Tips)
π₯ "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! |
β οΈ 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.
β 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. |
π V. Global Market Comparison (2026 Context)
| Country/Region | Recommended HS Code | Base Tariff | Additional Surcharges | Total Effective Rate | Notes |
|---|---|---|---|---|---|
| πΊπΈ USA | 3902.90.00.50 etc. |

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
