🧪 Fluoropolymer Powders: The "White Gold" of Industrial Chemistry (PTFE Fine Powder)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategies
📌 Part 1: Product Definition & Classification: Do You Really Understand "PTFE Fine Powder"?
Polytetrafluoroethylene (PTFE), commonly known as Teflon®, is a synthetic fluoropolymer. In international trade, "PTFE Fine Powder" (PTFE细粉) refers to the raw material form before sintering. It is not a finished product but an intermediate chemical good.
Internationally, it is strictly categorized based on its state and purity:
1. Primary Form (Raw Resin/Powder):
PTFE dispersion, PTFE resin, or PTFE powder that has not been processed into sheets, films, or tubes. This is where PTFE Fine Powder falls.
2. Key Distinction Points:
- VS. Finished Parts: If the powder is molded into bearings, seals, or rods → It becomes a "part of machinery" (Chapter 39 or 84/85).
- VS. Other Fluoropolymers: Must be strictly PTFE (Polytetrafluoroethylene). If it contains additives or is a copolymer like FEP/PFA, the HS code changes.
- Particle Size: "Fine powder" usually implies particle sizes <10 microns, used for coatings or dispersion.
⚠️ Critical Customs Warning:
- If the product is dispersed in water or solvent → It may be classified as a "Preparation" (Chapter 3904 vs 3901-3906 depending on formulation).
- If it is pure, dry, granular/powdered PTFE → It falls under Heading 3904.
- Never misdeclare as "Plastic Parts" or "Chemical Additives" without justification.
📦 Part 2: HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | State/Purity |
|---|---|---|---|
3904.61.00.00 |
Polytetrafluoroethylene (PTFE), in primary forms | Pure PTFE powder, granules, or flakes; raw material for manufacturing | ✅ Dry Powder / Resin |
3904.61.90.00 |
Other PTFE, in primary forms | Less common; usually for non-standard PTFE blends | ✅ Mixed/Blend |
3904.61.00.00 (Subheading 3904.61) |
PTFE, in primary forms | This is the standard code for PTFE powder | ✅ Standard |
3904.69.00.00 |
Other fluoropolymers (FEP, PFA, etc.) | If the product is NOT pure PTFE but other fluorinated ethylene plastics | ❌ Not PTFE |
3926.90.00.00 |
Other articles of plastics | If the powder is already processed into semi-finished shapes (e.g., sheets) | ❌ Not Powder |
🔍 Key Reminder:
-3904.61.00.00is the gold standard for PTFE Fine Powder.
- Ensure the product description explicitly states "PTFE, in primary forms" or "PTFE resin/powder, not further worked".
- If the powder is filled (e.g., with graphite, bronze, or glass fiber) for specific engineering properties, customs may still classify it under3904.61if the base polymer remains PTFE, but declaration must highlight the additives.

📌 Note:
- Do not try to down-classify PTFE to generic "other plastics" to avoid tariffs. Customs has advanced XRF scanning capabilities to verify fluorine content. Misclassification leads to penalties + back taxes.
🛠️ Part 4: Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
✅ 1. Documentation Checklist (Non-Negotiable)
| Document | Required | Notes |
|---|---|---|
| ✅ Certificate of Analysis (CoA) | ✔️ | Must specify Polymer Type: PTFE; Melt Flow Index (MFI); Ash Content |
| ✅ Material Safety Data Sheet (MSDS/SDS) | ✔️ | Critical for chemical classification; must state "Non-Hazardous" if applicable |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "PTFE POWDER, RAW MATERIAL, NOT FOR DIRECT CONSUMER USE" |
| ✅ Packing List | ✔️ | Net weight vs. Gross weight must be precise (chemicals are heavy) |
| ✅ Formulation Disclosure | ✔️ | If filled PTFE (e.g., 10% PTFE + 90% Bronze), declare composite nature |
| ✅ 301 Exclusion Certificate | ✔️ | If applicable, provide the Exclusion Number to reduce tariff |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Pure PTFE, 3904.61.00.00. If filled, declare additives. If dispersion, change code!"
| Scenario | Correct Declaration | Wrong Declaration |
|---|---|---|
| Pure PTFE Powder | 3904.61.00.00 - PTFE Resin/Powder |
"Plastic Powder" → 25% penalty risk |
| PTFE Dispersion (Water-based) | 3904.61.00.00 (if primary) or 3906.90.00.00 |
"Paint" → Wrong chapter (32) |
| Filled PTFE (e.g., Carbon-filled) | 3904.61.00.00 + Note: "Filled with Carbon" |
"Carbon Fiber Part" → Misclassification |
| PTFE Sheets/Flakes | 3904.61.00.00 (if still primary form) |
"Plastic Sheet" → Different tariff |
✅ 3. Special Situations
| Situation | Handling Advice |
|---|---|
| OEM Private Label | Ensure brand name does not imply "finished good." Use "Raw Material" in description. |
| Sample Shipments | Still subject to tariffs. Use Section 301 Exclusion if available. Do not use de minimis. |
| High Purity (>99.9%) | Declare purity level. May qualify for R&D exemptions in some cases. |
| Re-export from 3rd Country | If US-produced PTFE re-imported, no China tariff. But must prove US Origin (Form A). |

📌 Part 6: Common Errors & Pitfalls (Blood & Tears Lessons)
❌ Mistake 1: Declaring PTFE Powder as "Chemical Additive"
👉 Consequence: Customs may reject due to misclassification, leading to delays + fines. PTFE is a polymer, not an additive.
❌ Mistake 2: Ignoring TSCA (USA) or REACH (EU) Compliance
👉 Consequence: Goods seized at border. Chemical imports require pre-registration.
❌ Mistake 3: Using "Teflon" as Brand Name Without Authorization
👉 Consequence: Trademark Infringement. Use "PTFE" as generic term, not brand.
❌ Mistake 4: Not Disclosing Fillers (e.g., Bronze, Carbon)
👉 Consequence: If filled >5%, some customs administrations require different subheading. Be transparent.
✅ Correct Declaration Example:
"PTFE POLYMER POWDER, PRIMARY FORM, CAS NO. 9002-84-0, PURE, FOR INDUSTRIAL MANUFACTURING, TSCA COMPLIANT"
🎯 Part 7: Conclusion: Precision in Classification, Profit in Clearance!
🎯 Remember These Mantras:
🔹 "PTFE Powder = 3904.61.00.00. Not 'Plastic Parts'. Not 'Additives'."
🔹 "TSCA & REACH are mandatory. No compliance = No entry."
🔹 "301 Tariffs in USA are high. Check exclusion list every year."
📌 Pro Tip:
If your PTFE powder is high-purity (>99.9%) and used for medical or aerospace applications, explore US Chapter 98 or R&D Exemptions for potential tariff reduction.
📣 Immediate Action:
📞 Verify REACH/TSCA Registration with your supplier BEFORE shipment.
📄 Prepare MSDS & CoA in English.
🚀 Secure Section 301 Exclusion if shipping to the USA to save 25%+.
✨ Professional Clearance Starts with Accurate Classification!

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
