π§ͺ Indane Resin Modified Elastomer (Industrial Adhesives & Plastics)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
π I. Product Definition & Classification: What is "Indane Resin Modified Elastomer"?
This product refers to a specialized class of modified polymers where elastomers (rubber-like materials) are chemically or physically modified using Indane-based resins. In international trade, these materials are primarily used in two distinct categories depending on their final form:
- Prepared Adhesives: If the material is formulated into a glue, paste, or tacky substance suitable for bonding other materials.
- Plastic Articles/Resins: If the material is sold as a raw polymer resin or molded plastic article intended for industrial or construction applications.
β οΈ Key Distinction:
- If the product is a glue/adhesive (especially retail-packaged <1kg) β Classified under Chapter 35 (Prepared Glues).
- If the product is a raw polymer/resin or plastic article β Classified under Chapter 39 (Plastics and Articles Thereof).

| Item | Content |
|---|---|
| Tax Status | ERROR: Failed to Retrieve |
| Recommendation | Do NOT use these codes without verification. |
| Action | Contact a licensed customs broker for a Pre-Ruling (ISF/HTS Binding Ruling). |
π Important:
- The system could not retrieve tax data for these codes. This likely indicates complex or changing tariff structures for specific chemical copolymers.
- Do not guess the HS Code for raw materials. A wrong classification here can lead to massive penalties and shipment delays.
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
β 1. Essential Documentation Checklist
| Document | Mandatory? | Explanation |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must state: "Modified Elastomer," "Indane Resin Content," "Adhesive vs. Raw Resin" |
| β Formula/Composition List | βοΈ | Critical for determining if it falls under Chapter 35 (Adhesive) or Chapter 39 (Polymer) |
| β Intended Use Declaration | βοΈ | Crucial: Is it for general bonding (0% tax) or display manufacturing (25% tax)? |
| β Safety Data Sheet (SDS) | βοΈ | Required for chemical handling and customs inspection |
| β Commercial Invoice | βοΈ | Must clearly distinguish "Adhesive" from "Plastic Resin" |
β 2. Classification Strategy & Tips
π₯ "Adhesive vs. Resin: The 25% Trap!"
| Scenario | Correct HS Code | Tax Rate | Reason |
|---|---|---|---|
| General Purpose Glue (e.g., for woodworking, packaging) | 3506.91.50.00 |
0% | Not for optical displays; no additional tariff. |
| Display Adhesive (e.g., for LCD/OLED assembly) | 3506.91.10.00 |
25% | Specifically for flat panel/touch screen manufacturing. |
| Raw Resin Pellets (Not yet formed into adhesive) | 3907.99 / 3915.90 |
Unknown | Requires Broker Consultation. Do not self-classify. |
| Plastic Scrap/Waste | 3915.90 |
Unknown | Requires Broker Consultation. |
β 3. Special Case Handling
| Situation | Handling Suggestion |
|---|---|
| Dual-Use Product | If the adhesive could be used for displays but is marketed generally, declare as 3506.91.50.00 only if it is not principally for displays. Provide evidence of non-display use. |
| OEM for Electronics | If you are supplying a display manufacturer, you MUST use 3506.91.10.00. Declare accordingly. |
| Raw Material Import | STOP. Do not clear this without a Binding Ruling from CBP. The tax data is missing, and risk is high. |

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
