π Part 1: Product Definition & Classification: Do You Really Understand "Polyamide"?
Polyamide (PA), commonly known as Nylon, is a versatile synthetic polymer widely used in automotive, electronics, and industrial applications due to its high strength, heat resistance, and insulation properties. In international trade, the classification depends heavily on its form (pellets, powder, granules) and additives (fillers, reinforcing materials).
Key Distinctions:
- Raw Material Form: Typically supplied as pellets, granules, or powder for injection molding or extrusion.
- Insulation Property: Refers to its electrical insulation capabilities, not necessarily a finished insulating product (like cables).
- Reinforced vs. Pure: Additives like glass fiber (GF) significantly alter the HS code classification.
β οΈ Critical Classification Point:
- If it is plain polymer (nylon pellets/powder) β Usually 3903.30 or 3903.90.
- If it is reinforced (e.g., with glass fiber) β May shift to 3903.30 or 3903.90 depending on the base polymer.
- If it is a finished insulating component (e.g., pre-formed bushings) β May fall under 8546 or 8538.
Note: The query "Raw Material" strongly implies polymers in pellet/powder form.
π¦ Part 2: HS Code Classification Details (2026 Latest Tariff Authority Cross-Reference)
| HS Code | Product Description | Application Scenario | Key Characteristics |
|---|---|---|---|
3903.30.00.00 |
Polymers of acrylonitrile-butadiene-styrene (ABS) | Not PA | β Incorrect for Polyamide |
3903.90.00.00 |
Other primary forms of acrylonitrile-butadiene-styrene (ABS) | Not PA | β Incorrect for Polyamide |
3902.30.00.00 |
Copolymerization of styrene | Not PA | β Incorrect for Polyamide |
3904.10.00.00 |
Polyamides in primary forms (Nylon 6, 66, etc.) | Standard Nylon Pellets/Powder | β Pure or lightly modified PA |
3904.90.00.00 |
Other polyamides in primary forms | Specialty Polyamides (e.g., PA 46, PA 12, PA 610) | β Non-standard or high-performance PA |
3903.00.00.00 |
Polymers of styrene | Not PA | β Incorrect for Polyamide |
3909.50.00.00 |
Urea resin melamine resin and phenolic resin | Not PA | β Incorrect for Polyamide |
π Key Reminder:
- "Polyamide" falls primarily under Chapter 39, Heading 3904.
- Nylon 6 (PA6) and Nylon 66 (PA66) are the most common and fall under 3904.10.
- Specialty Polyamides (e.g., PA11, PA12, PA46) fall under 3904.90.
- If the material is already processed into finished insulators (not raw material), it may fall under 8546 (Insulators) or 8538 (Parts of Electrical Machinery), but the term "Raw Material" points to 3904.

π Part 6: Common Errors & Pit-Avoidance Guide (Blood Lessons)
β Error 1: Declaring "Nylon" as "Plastic Parts"
π Consequence: If inspected, may be reclassified to 3904 with back taxes + penalties!
β Error 2: Ignoring additive content (e.g., GF%)
π Consequence: If GF content is significant, may affect HS code or trigger anti-dumping investigations
β Error 3: Providing incomplete SDS
π Consequence: Customs may halt inspection, causing delay or return
β Error 4: Using "Insulated Material" as a vague name
π Consequence: Customs may misclassify as finished electrical component β higher tariff
β Correct Practice:
"Polyamide 6 (Nylon 6) Raw Material, Pellets, Virgin, Unreinforced, for Injection Molding, Chemical Resistant, High Heat Resistance, Certified RoHS/REACH"
π― Part 7: Conclusion: Professional Declaration, Save Time and Money!
π― Remember the Mantra:
πΉ "Raw Material = 3904, Form is Key, Additives Matter, US Tariff 37.8%!"
πΉ "HS Code Determines Fate, Tariff Differs by 30 Points, Declaration Error Costs Thousands!"
π Tips:
- If your Polyamide originates from Vietnam, Mexico, Thailand, Malaysia, you may apply for IEEPA Exemption, tariff reduced to 5.3%;

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
