π HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What is "Extrusion Grade PTFE"?
PTFE (Polytetrafluoroethylene), commonly known by the brand name Teflonβ’, is a high-performance fluoropolymer known for its exceptional chemical resistance, low friction, and high thermal stability.
"Extrusion Grade" specifically refers to PTFE resin formulated with specific particle sizes, binder content, or processing aids to allow it to be pushed through a die (extruder) to create continuous shapes such as rods, tubes, sheets, and profiles.
Key Distinction in Classification: * Primary Raw Material vs. Semi-Finished Good: PTFE Resin in powder or granular form is classified as a raw plastic material. * Not Fabricated Articles: It is not yet a finished "article" (like a gasket or pipe section) unless it has been further processed into a specific shape with a defined function beyond basic manufacturing stock.
β οΈ Critical Classification Point:
- If it is powder, pellets, or granules (even if labeled "for extrusion"): It is a raw plastic material β HS 3904.
- If it is already shaped into rods/tubes ready for sale as stock items: It may be classified as a semi-finished plastic article β HS 3926 (depending on specific country interpretation, but US typically keeps it in 3904 if it's still generic stock, or 3926.90 if highly specific finished goods).
- Standard Import Practice: Most "Extrusion Grade Resin" imports are declared as raw plastic material under 3904.
π¦ II. HS Code Classification Details (2026 Latest Tariff Concordance)
| HS Code | Product Description | Applicability | Key Differentiator |
|---|---|---|---|
3904.61.00.00 |
Polymers of tetrafluoroethylene, in primary forms | Most Common | Powder, granules, or pastes intended for extrusion. This is the standard code for "PTFE Resin." |
3904.69.00.00 |
Other polymers of tetrafluoroethylene | Less Common | For non-standard PTFE blends or modified PTFE not covered under 3904.61. |
3926.90.97.98 |
Other articles of plastics (e.g., PTFE rods/tubes) | Semi-Finished | Only if the product is already formed into specific shapes (rods, sheets) sold as inventory, not just raw material. |
π Key Reminder for Customs:
- "Resin" = 3904.61.00.00: Even if the technical data sheet says "for extrusion," if the physical form is powder/granules/paste, it is Primary Form.
- "Rod/Tube Stock" = 3926: Only if the item is a finished cylindrical shape.
- Misclassification Risk: Declaring a raw powder as a "finished article" to avoid higher duties on finished goods is a red flag. Conversely, declaring a finished part as raw material may lead to detention if physical inspection reveals shaped goods.

π Explanation:
- 35% Total Duty is significant for chemical imports.
- PTFE is a high-value, critical material. Customs may scrutinize the "primary form" claim. Ensure your shipment is indeed powder/granules/paste, not pre-formed parts.
- No De Minimis: Shipments under $800 are not exempt. All shipments are subject to duty.
π― 2. 3926.90.97.98 ββ Other Plastic Articles (If misclassified as shaped stock)
| Item | Content |
|---|---|
| Base Tariff | 5.3% |
| USITC Surtax (Section 301) | +25% |
| IEEPA Surtax | +10% |
| Total Duty Rate | 40.3% |
| Calculation | CIF Value Γ 40.3% |
π Note: If you import PTFE rods or tubes (already formed), they may fall under HS 3926. The duty is higher (40.3%) than raw resin (35%). Importing as "Resin" is cheaper but must be physically accurate.
π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (Non-Negotiable)
| Document | Required | Explanation |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must state "PTFE Resin," form (powder/granule), molecular weight, binder content. |
| β Material Safety Data Sheet (MSDS/SDS) | βοΈ | Required for chemical imports. Classify as "Non-Hazardous" or "Flammable Solid" as per GHS. |
| β Commercial Invoice | βοΈ | Must clearly describe: "PTFE (Polytetrafluoroethylene) Resin, Extrusion Grade, Primary Form." |
| β Packing List | βοΈ | Detail net/gross weight. PTFE is dense; ensure weight accuracy. |
| β Certificate of Origin (CO) | βοΈ | If claiming exemptions or verifying origin for Section 301/IEEPA. |
| β FCC/UL/ROHS Certificates | β | Not required for raw resin, but good for traceability. |
β 2. Declaration Strategy (Key Mantra)
π₯ "Form Determines Code, Not Function!"
| Scenario | Correct HS Code | Wrong Practice |
|---|---|---|
| PTFE Powder/Pellets (for you to extrude later) | 3904.61.00.00 (35%) |
Declare as "Plastic Rods" β 40.3% + Misdeclaration Penalty |
| PTFE Paste (for dipping/extrusion) | 3904.61.00.00 (35%) |
Declare as "Chemical Mixture" β Incorrect Classification |
| Pre-made PTFE Rods/Tubes (sold as stock) | 3926.90.97.98 (40.3%) |
Declare as "Resin" β Detention & Seizure Risk |
| PTFE Coated Fiberglass Fabric | 5903.20.00.00 |
Mix with resin declarations β Complex Duty Calculation |
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom PTFE | Provide formulation details. If unique binder, ensure it doesn't change the chemical nature from "homopolymer." |
| Hybrid Materials (PTFE + Carbon/Glass) | If PTFE is the principal material, 3904.61.00.00 usually applies. If carbon fiber dominates, may shift to 3903.30 (Fluoropolymers) or 3926. Verify with chemist. |
| Small Samples | Still subject to 35% duty. No de minimis. Plan budget accordingly. |
π V. Global Market Comparison (2026 Latest)

- China is the global hub for PTFE production; importing from China to US is common but expensive.
π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Declaring PTFE Rods as PTFE Resin to save 5.3% duty.
π Consequence: Customs inspection reveals shaped goods. Seizure, fines, and possible criminal charges for fraud.
β Error 2: Ignoring SDS/MSDS.
π Consequence: Delay at port for chemical review. Potential detention if classification of "flammability" is disputed.
β Error 3: Assuming De Minimis ($800) applies to small lab samples.
π Consequence: 35% duty still applies. Budget for duties even on small shipments.
β Error 4: Vague Description "Plastic Material."
π Consequence: Customs exam required. Delay of 5-14 days. Use specific terms: "Polytetrafluoroethylene (PTFE) Resin, Powder, Extrusion Grade."
β Correct Declaration Example:
"POLYTETRAFLUOROETHYLENE (PTFE) RESIN, EXTRUSION GRADE, POWDER FORM, NON-HAZARDOUS, HS 3904.61.00.00"
π― VII. Conclusion: Professional Declaration, Cost Control, Compliance!
π― Remember the Mantra:
πΉ "Powder/Granule = 3904 (35%) | Shaped Rod = 3926 (40.3%)"
πΉ "No De Minimis for Chemicals | Always Provide SDS"
πΉ "Misclassification = Seizure | Accuracy = Speed"
π Pro Tip:
If you are importing large volumes, consider Advance Rulings from CBP (US Customs) to lock in the HS classification. Also, verify if your supplier can provide Form A or other FTA certificates if sourcing from non-China origins (e.g., Vietnam, India) to mitigate IEEPA/301 taxes.
π£ Immediate Action:
π Contact your Customs Broker + Provide SDS + Verify Physical Form (Powder vs. Shaped)
π Ensure your PTFE Resin flows smoothly, legally, and cost-effectively across borders!
β¨ Precision in Classification Saves Thousands!

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
