π I. Product Definition & Classification: Do You Know What "Fluoropolymer Raw Material" Is?
Fluoropolymer sheets, primarily made of Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), or Ethylene tetrafluoroethylene (ETFE), are high-performance engineering plastics known for extreme chemical resistance, high heat tolerance, and low friction. In international trade, "raw material" typically refers to unprocessed or semi-processed sheets/plates before they are cut into final products (like gaskets, linings, or non-stick coatings).
Key Distinction:
- Resin/Granules (PTFE Powder): Raw polymer in powder form β Classified under 3901/3902.
- Sheets/Plates (Semi-finished): Solid sheets with defined thickness/width, not yet shaped into specific articles β Classified under 3920/3921.
- Finished Articles (Gaskets, Membranes): Cut to specific shapes/functions β Classified under 3926.90 or specific machinery parts.
β οΈ Critical Differentiator:
- If the item is a solid sheet/plate (even if uncolored or unpainted), it falls under Chapter 39 (Plastics and Articles Thereof), specifically Heading 3920 (Other plates, sheets, film, foil and strip, of plastics) or 3921 (Other plates, sheets, film, foil and strip, of plastics).
- Do NOT classify as "parts of machinery" unless it is specifically shaped for a machine.
- Do NOT classify as "textiles" even if reinforced with fiberglass (unless the plastic is merely a coating on a textile base, then check 5903).

| HS Code | Product Description | Application Scenario | Form Factor |
|---|---|---|---|
3920.10.90.00 |
Other plates, sheets, film, foil and strip, of PTFE (Polymers of Ethylene) | PTFE sheets, raw, unprinted, for further processing | β Solid Sheet |
3920.10.10.00 |
Plates, sheets, film, foil and strip, of PTFE | High-purity PTFE industrial sheets | β Solid Sheet |
3920.10.00.00 |
Other plates... of Polymers of Ethylene (Broad Category) | Includes ETFE, FEP sheets | β Solid Sheet |
3921.13.00.00 |
Other plates, sheets... of Polymers of Vinyl Chloride (Less common for fluoro) | PVDF sheets (if classified here, less common for pure FPM/PTFE) | β Solid Sheet |
3920.51.00.00 |
Other plates, sheets... of Polymers of Propylene | Not Fluoropolymer | β N/A |
3926.90.98.00 |
Other articles of plastics | Finished PTFE gaskets, rings, or molded parts | β Finished Good |
π Key Reminder:
- PTFE (Polytetrafluoroethylene) is the most common fluoropolymer for sheets. It is chemically classified under "Polymers of Ethylene" in HS Code 3920.10.
- PVDF (Polyvinylidene Fluoride) is often classified under 3920.10 or 3921 depending on the specific resin type and manufacturer classification, but 3920.10.90 is frequently used for semi-finished PVDF sheets in many jurisdictions.
- Reinforced Fluoropolymers (e.g., PTFE with fiberglass): If the plastic component is the essential character, it remains in 3920. If the fiberglass is dominant, it may shift to Chapter 70 or 59, but usually, plastic-coated fiberglass sheets stay in 3920.10 or 3921.13 if PVC-based. For pure fluoropolymer sheets, 3920.10 is standard.

π Explanation:
- The base duty for PTFE sheets is relatively low (5.3%) because it is considered a raw industrial material.
- However, due to Section 301 (USITC Footnote 9903.01.24), an additional 7.5% is applied.
- The new IEEPA 10% surcharge (effective Nov 10, 2025) adds another layer.
- Total Effective Duty: 22.8%. This is significantly higher than the base rate, eroding margins for importers.
π― 2. 3921.13.00.00 ββ PVDF/Other Fluoropolymer Sheets (If Applicable)
| Item | Content |
|---|---|
| Base Duty Rate | 5.6% (ad valorem) |

| Legal Path | USITC:3921.13.00.00 β FOOTNOTE:9903.01.24 β IEEPA:9903.01.24 |
π Note:
- If your fluoropolymer sheet is PVDF-based and classified under 3921.13, the duty is slightly higher (23.1%).
- Always confirm the polymer type (PTFE vs. PVDF) as it determines the 3-digit heading (3920 vs. 3921).
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Required Documentation Checklist (No Exceptions)
| Document | Required | Notes |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must state: Polymer Type (PTFE/PVDF/ETFE), Grade, Thickness, Width, Color. |
| β Material Safety Data Sheet (MSDS/SDS) | βοΈ | Mandatory for chemical/plastic imports. |
| β Commercial Invoice | βοΈ | Must clearly describe as "Fluoropolymer Sheet, Unprocessed" or "PTFE Sheet". Avoid vague terms like "Plastic Part". |
| β Packing List | βοΈ | Detail net/gross weight, number of rolls/sheets. |
| β Certificate of Origin (CO) | βοΈ | If claiming any FTZ exemptions (rare for CN origin). |
| β Import License (if applicable) | β | Generally not required for PTFE sheets, but check for any special controls. |
β 2. Declaration Tips (Key Mantra)
π₯ "Specify Polymer, Declare Form, Avoid 'Article' Trap!"
| Scenario | Correct Declaration | Wrong Declaration |
|---|---|---|
| PTFE Sheets, 1mm thick, rolls | 3920.10.90.00 β PTFE Sheets |
"Plastic Liner" β Misclassified as 3926 (Finished Good) |
| PVDF Sheets, for chemical lining | 3921.13.00.00 β PVDF Sheets |
"Chemical Resistant Material" β Vague, leads to audit |
| PTFE Gaskets (Cut to size) | 3926.90.98.00 β Articles of Plastic |
"Fluoropolymer Sheet" β Incorrect, higher scrutiny |
π Critical Warning:
- Do NOT declare as "Gaskets" or "Linings" if you are importing raw sheets.
- Do NOT declare as "Resin" if you are importing solid sheets.
- Misclassification can lead to back duties (22.8% vs. 0% if wrongly classified as resin with lower duty) or penalties.
β 3. Special Cases
| Scenario | Handling Advice |
|---|---|
| Reinforced PTFE (Fiberglass) | Still classified under 3920.10 if plastic is essential character. Provide composition % in specs. |
| Colored vs. Natural PTFE | Both fall under 3920.10. Color does not change HS code. |
| Sample Sheets for Testing | Same HS code applies. Duty is still owed unless under a specific sample exemption (rare for CN origin). |
| Return of Defective Sheets | May qualify for Import Relief if re-exported, but requires strict documentation. |

π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Declaring PTFE Sheets as "Plastic Articles" (3926.90)
π Consequence: Wrong HS code β Potential audit for undervaluation or misclassification. Duty may differ, but more importantly, it raises suspicion of smuggling finished goods as raw materials.
β Error 2: Omitting "PTFE" or "Fluoropolymer" in Description
π Consequence: Customs may classify under a generic "Plastic Sheet" heading with higher duty or stricter scrutiny. Always be specific.
β Error 3: Not Providing MSDS/SDS
π Consequence: Shipment held at port for chemical safety review β Delays + Storage Fees.
β Error 4: Assuming "Raw Material" means "Resin/Granules"
π Consequence: Misclassification as 3901 (Resin) β Penalty for false declaration. Sheets are processed plastics, not raw resins.
β Correct Practice:
"PTFE Sheets, Unprocessed, 1mm Thickness, 1200mm Width, Natural Color, For Industrial Linings, Material: Polytetrafluoroethylene"
π― VII. Conclusion: Professional Declaration Saves Money!
π― Remember the Mantra:
πΉ "Sheets are 3920, Resins are 3901, Don't Mix Them Up!"
πΉ "22.8% Duty in US, Check FTA for 0% Elsewhere!"
πΉ "Specify PTFE/PVDF, Provide MSDS, Avoid Delays!"
π Pro Tip:
If your fluoropolymer sheets are originating from Vietnam, Malaysia, or Thailand, you may qualify for zero duty under USMCA (if applicable rules of origin are met) or ASEAN-US FTAs.
Recommendation: Apply for an Advance Ruling from US Customs if you are importing large volumes. This provides legal certainty on the 22.8% duty and helps in budgeting.

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
