๐ HS Code Classification & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
๐ I. Product Definition: What is "Sealing Grade Ethylene Elastomer Resin"?
"Sealing Grade Ethylene Elastomer Resin" refers to high-performance polymer materials primarily composed of ethylene polymers. In international trade, these materials are categorized based on their physical form (resin vs. finished shape) and specific application (medical grade vs. acoustic/sealing grade).
Key Distinctions: * Medical Grade: Formulated to meet strict biocompatibility standards, often classified as "Resin" due to its raw material state. * Sealing/Acoustic Grade: Designed for sound insulation or sealing applications, often processed into specific forms or classified under broader polymer categories like Polyethylene.
โ ๏ธ Critical Classification Point:
- If the material is in its raw resin form intended for medical use โ Classified under 3901.90.10.00.
- If the material is for general/sealing/acoustic use in raw form โ Classified under 3901.90.90.00 or 3921.19.00.10.
๐ฆ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Application Scenario | Physical Form |
|---|---|---|---|
3901.90.10.00 |
Medical Grade Ethylene Elastomer Resin: Ethylene-based, resin form, conforms to elastomer definition. | Biocompatible medical components, surgical seals, tubing. | โ Resin (Raw) |
3901.90.90.00 |
Medical or Acoustic Grade Ethylene Elastomer Resin: Ethylene polymer, original/primary form. | General sealing, acoustic insulation, general industrial use. | โ Primary Form |
3921.19.00.10 |
Acoustic Grade Ethylene Elastomer Resin: Polyethylene category, other forms matching logic. | Soundproofing materials, specialized sealing gaskets (non-resin form). | โ ๏ธ Other/Processed |
๐ Key Reminder:
- Medical Grade products typically fall under 3901.90.10.00 due to their specific "resin" state and medical purpose.
- Sealing/Acoustic Grade products may be classified under 3901.90.90.00 (if primary form) or 3921.19.00.10 (if processed for acoustic/sealing purposes).
- Do not mix medical and non-medical grades in a single shipment without clear separation.

๐ ๏ธ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
โ 1. Required Documentation Checklist (Must-Haves)
| Document | Mandatory? | Description |
|---|---|---|
| โ Product Specification Sheet | โ๏ธ | Must clearly state "Ethylene Elastomer," "Medical Grade" or "Acoustic Grade," and physical form (Resin vs. Sheet). |
| โ Certificate of Origin (CO) | โ๏ธ | Essential for determining applicability of surcharges. |
| โ Commercial Invoice | โ๏ธ | Must match HS Code exactly. Avoid vague terms like "Plastic Material." |
| โ Third-Party Test Report | โ๏ธ | For medical grade: Biocompatibility test (ISO 10993). For acoustic grade: Sound transmission class (STC) rating. |
| โ Packaging List | โ๏ธ | Detail net/gross weight and number of packages. |
โ 2. Declaration Tips (Key Mantras)
๐ฅ "Form Determines Code, Grade Determines Rate, Vague Descriptions Cost Money!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Medical Grade Resin | 3901.90.10.00 - "Medical Grade Ethylene Elastomer Resin" |
Misdeclare as general plastic โ 41.5% |
| Acoustic Grade Resin (Primary Form) | 3901.90.90.00 - "Ethylene Polymer Resin for Acoustic Insulation" |
Misdeclare as medical โ 35% (if accepted) or penalty |
| Acoustic Grade (Processed/Form) | 3921.19.00.10 - "Acoustic Insulation Ethylene Elastomer Sheet" |
Misdeclare as raw resin โ Delayed clearance |
| Mixed Shipment | Split declarations for different HS Codes | Mixed shipment โ Risk of audit & penalties |
โ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Grades | Provide client order + technical datasheet to prove "Medical" or "Acoustic" classification. |
| Resin vs. Sheet | Ensure physical form matches HS Code definition. Resin = 3901; Sheet/Plate = 3921. |
| Hybrid Applications | If product serves both medical and acoustic purposes, declare as Medical if primary intent is medical (lower base rate). |
| Transshipment | Direct shipment from China to US is critical. Third-country transshipment may not exempt from Section 301/122. |

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) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ 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 โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
