π§ͺ Copolymer Injection Grade Resin (Diamino-3-Methylcyclohexylmethane Isophthalic Acid Lauryl Lactam Copolymer)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy π 1. Product Definition & Classification: Do You Understand the "Resin"?
This product is a complex synthetic polymer resin specifically formulated for injection molding. Its chemical composition involves a copolymerization of several key components: * Diamino-3-Methylcyclohexylmethane: An amine hardener/curing agent. * Isophthalic Acid: A monomer often used to modify polyester properties (e.g., impact resistance). * Lauryl Lactam: A key component in Nylon 12 (Polydodecalactam) synthesis.
β οΈ Key Classification Logic: The term "Resin" (ζ θ/εζ) combined with "Injection Grade" (ε°εΊηΊ§/注ε‘ηΊ§) clearly indicates that this is a primary form of a polymer. It is not a finished article (like a molded part) but rather the raw material used to make parts. Therefore, it falls under Chapter 39: Plastics and Articles Thereof, specifically under Heading 3907 (Polyacetals, Other Polyethers, and Epoxide Resins; Polycarbonates, Alkyd Resins, Polyallyl Esters and Other Polyesters).
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided data, there are two primary competing HS Codes for this resin, both carrying the same total tax burden. The distinction lies in the specific chemical family classification.
| HS Code | Product Description | Classification Logic | Conflict Check |
|---|---|---|---|
3907.61.00.50 |
Polyesters (Other) Specifically: Isophthalic Acid-based Copolymers |
Match Basis: The product contains "Isophthalic Acid" (θε―Ήθ―δΊη²ι Έ/εΌι ι Έ), which is a key monomer for Polyesters. The summary confirms "Copolymer Resin" matches "Primary Forms" (εηΊ§ε½’ζ). | β No Conflict: "Injection Grade" confirms it is a raw material/resin form, fitting the "Other Polyesters" category under 3907.61. |
3907.29.00.00 |
Other Polyacetals, Other Polyethers, and Other Epoxide Resins; Polycarbonates, Alkyd Resins, Polyallyl Esters and Other Polyesters Specifically: Other Polyesters/Resins not elsewhere specified |
Match Basis: The summary states "Resin" matches "Polyether/Polyester" attributes. "Lauryl Lactam" suggests Nylon-like (Polyamide) structures, but if classified under the "Polyester" umbrella of 3907, it falls here as "Other". | β No Conflict: "Injection Grade" is typical for "Primary Forms". The summary notes no material conflict with "Polyether/Polyester" broad categories. |
π Critical Insight: - Both codes (
3907.61.00.50and3907.29.00.00) represent primary forms of polymers. - The choice between them often depends on the dominant chemical structure or the importer's specific classification expertise. - Crucially, the TOTAL TAX RATE is IDENTICAL for both codes.

π Explanation: - "Base Tariff 6.5%": The standard Most Favored Nation (MFN) duty for these resin types. - "301 Tariff 25%": The ongoing penalty imposed on Chinese goods under Section 301 of the Trade Act. - "122 Clause Tariff 10%": This refers to the Section 122 authority (or overlapping IEEPA authorities) which allows the President to adjust duties for national security or economic reasons. In the context of the provided data, this is an additional 10% surcharge on top of the 301 tariff. - Total: 6.5 + 25 + 10 = 41.5%. This is a very high cost for raw materials.
π οΈ 4. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Required Documentation Checklist (Non-Negotiable)
| Document | Required | Explanation |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must explicitly state "Copolymer Resin", "Injection Grade", and chemical composition (Isophthalic Acid, Lauryl Lactam, etc.). |
| β Material Safety Data Sheet (MSDS) | βοΈ | Required for chemical handling and customs verification of hazardous properties. |
| β Commercial Invoice | βοΈ | Must use precise description: "Copolymer Injection Grade Resin for Plastic Molding". Avoid vague terms like "Plastic Material". |
| β Certificate of Origin (CO) | βοΈ | Critical for proving Chinese origin to apply (or challenge) the 301 and 122 tariffs. |
| β Packaging List | βοΈ | Detail net weight/gross weight. Resins are often shipped in bags/boxes. |
| β Third-Party Lab Report | Optional but Recommended | Proves the chemical structure is a "Copolymer" and not a pre-formed "Article" (which might have different duties). |
β 2. Declaration Tips (Key Mantra)
π₯ βDeclare βResinβ, Not βArticleβ; βInjection Gradeβ is King!β
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Raw Resin Pellets/Granules | Use "Copolymer Resin, Injection Grade" β HS 3907 |
Declare as "Plastic Parts" β Wrong Chapter, higher penalty. |
| Pre-molded Parts | HS 3926 (Articles of Plastics) |
Declare as "Resin" β Misdeclaration, potential fraud charge. |
| Mixed Shipment | Split invoice: Resin vs. Other | Combine β Customs may reject or delay. |
π Note: Ensure the description emphasizes "Primary Form" (εηΊ§ε½’ζ). If the goods are already molded (e.g., pre-formed beads or pre-cut shapes that are clearly finished components), the classification may shift to HS Code 3926 (Articles of Plastics), which might have a different (often lower) base rate but still subject to 301/122 tariffs. However, the provided data explicitly links "Injection Grade" to 3907, implying raw resin.
β 3. Special Considerations
| Situation | Handling Advice |
|---|---|
| OEM Custom Resin | Provide customer PO and formulation specs. Ensure the chemical name matches the HS code justification (Isophthalic = Polyester). |
| Bilingual Documentation | Use both English and Chinese names if importing from China: "Copolymer Resin (ε ±θζ θ)". |
| Tariff Engineering | Consult a customs broker: Is it possible to classify under HS 3906 (Acrylic Polymers) if Lauryl Lactam (Nylon) dominates? Note: The data provided only supports 3907.61 or 3907.29. Do not assume 3906 without expert advice. |
| Volume Discounts | Given the 41.5% tax, consider Bonded Warehouses or Foreign Trade Zones (FTZ) to defer duty payment. |
π 5. Global Market Comparison (2026 Update)
| Country/Region | Recommended HS Code | Estimated Total Tax | Certification | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 3907.61.00.50 / 3907.29.00.00 |
41.5% (6.5 + 25 + 10) | FDA (if food contact), RoHS | Highest cost. No de minimis. |
| π¨π³ China | 3907.61.00.00 |
6.5% | CCC (if applicable) | No 301/122 surcharges. |
| πͺπΊ EU | 3907.61 / 3907.29 |
5.3% | REACH, RoHS | No 301/122 equivalent. |
| π¨π¦ Canada | 3907.61 / 3907.29 |
0% (CUSMA) | FDA/Health Canada | Free trade if Canadian origin. |
| π²π½ Mexico | 3907.61 / 3907.29 |
0% (USMCA) | NOM | Free trade if Mexican origin. |
π Conclusion: - USA is the most expensive market due to the 41.5% cumulative tariff. - Europe and Asia offer significantly lower tariffs. - Supply Chain Strategy: If selling to the US, consider third-party country assembly or tariff engineering (if legally permissible) to reduce costs.
π 6. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Declaring as "Plastic Pellets" without specifying "Resin/Copolymer". π Consequence: Customs may misclassify, leading to audits or penalties.
β Mistake 2: Ignoring the 10% Section 122/IEEPA surcharge. π Consequence: Underpayment of duty. 41.5% vs 31.5% is a significant difference.
β Mistake 3: Using "Injection Molding Compounds" vs "Resin" incorrectly. π Consequence: If additives >10%, it might be a "Compound" (HS 3907.61/29). The provided data assumes it is a Resin (Primary Form). Ensure the product is not a pre-mixed compound with >10% other substances unless declared as such.
β Correct Practice:
"Copolymer Resin, Injection Grade, Contains Isophthalic Acid & Lauryl Lactam, Primary Form, Not Pre-Molded"
π― 7. Conclusion: Precision Declaration Saves Money!
π― Remember the Mantra:
πΉ "Resin is Primary, Injection Grade is Key!" πΉ "41.5% Tax is Real, Don't Get Caught Off Guard!" πΉ "Isophthalic = Polyester, Lauryl Lactam = Nylon-like, But 3907 Wins!"
π Tips: - If your resin is originating from Vietnam, Malaysia, or Thailand, you MAY be eligible to avoid the 25% 301 tariff, reducing the total to ~16.5%. - Always apply for an Advance Ruling from US Customs (CBP) to lock in the HS Code before shipment. - For high-volume shipments, consider duty drawback programs if the goods are re-exported.

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
