🧪 Fluoropolymer Injection Molding Compound (PTFE/PFA/FEPM)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
📌 I. Product Definition & Classification: Do You Truly Understand "Fluoropolymer"?
Fluoropolymer Injection Molding Compounds are high-performance thermoplastic materials primarily composed of polytetrafluoroethylene (PTFE), perfluoroalkoxy (PFA), or fluoroelastomers (FEPM). They are renowned for extreme chemical resistance, high-temperature stability, and low friction coefficients.
In international trade, these materials are rarely classified as simple "plastics." They are distinct categories based on their chemical composition and physical form:
- Primary PTFE/PFA Resins: Unmolded, raw compound powders or granules intended for subsequent processing.
- Semifinished Articles: Rods, sheets, or tubes that are already shaped but require further manufacturing.
- Finished Parts: Gaskets, seals, or specific components (if imported as such).
⚠️ Critical Distinction Point:
- If the product is raw powder/granules in plastic bags/drums → Classify under Chapter 39 (Articles of Plastics).
- If the product is pre-shaped rods/tubes → Classify under Chapter 39 (Semicircles/Rods).
- If the product is finished gaskets/seals → Classify under Chapter 40 (Rubber Articles) or 3926 (Other Plastic Articles), depending on material composition.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Form |
|---|---|---|---|
3901.10.00.00 |
Polyethylene, primary form (Note: Rare for Fluoropolymers, but check base polymer if copolymer) | Not typically applicable for pure PTFE | ❌ N/A |
3904.21.00.00 |
Polytetrafluoroethylene (PTFE), in primary forms | Raw PTFE powder, granules, pellets for injection molding | ✅ Primary Form |
3904.30.00.00 |
Fluoropolymers other than PTFE (e.g., PVDF, PFA, FEP) in primary forms | Raw PFA/PVDF granules for molding | ✅ Primary Form |
3926.90.97.95 |
Other articles of plastics (Semicircles, Rods, Tubes) | Pre-extruded PTFE rods/tubes for machining | ✅ Semi-finished |
4016.93.00.00 |
Other articles of vulcanized rubber having special properties | Fluoroelastomer (FKM/Viton) seals/gaskets | ✅ Finished Part |
🔍 Key Reminder:
- PTFE falls under 3904.21.
- PFA/FEP/PVDF fall under 3904.30.
- Never classify raw fluoropolymer powder under "Chemicals" (Chapter 29) or "Miscellaneous" (Chapter 38). It is strictly an article of plastic (Chapter 39) in primary form.

📌 Note:
- PFA (Perfluoroalkoxy) and FEP (Fluorinated Ethylene Propylene) are classified under "Other Fluoropolymers."
- Like PTFE, they face the same heavy tariff burden. Do not confuse them with standard thermoplastics like PE or PP, which may have lower rates.
🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (All Mandatory)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify exact polymer type (PTFE vs. PFA), melt flow index, filler content (e.g., glass-filled, carbon-filled). |
| ✅ Safety Data Sheet (SDS) | ✔️ | To confirm non-hazardous classification and chemical identity. |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Plastic Material, Primary Form" NOT "Chemical Raw Material." |
| ✅ Certificate of Origin (CO) | ✔️ | Crucial for verifying origin. If re-processed in Vietnam/Malaysia, apply for Form E or AHTCN if applicable. |
| ✅ Packing List | ✔️ | Detail net/gross weight. Ensure packaging is sealed to prevent contamination. |
| ✅ FCC/Proposition 65 Compliance | ✔️ | Some fluoropolymer additives may trigger consumer protection alerts in the US. |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Form Matters, Polymer Name Precise, No 'Chemicals' Ambiguity!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Raw PTFE Powder | 3904.21.00.00 - "PTFE Resin, Primary Form" |
Misdeclare as "Chemical Reagent" (Chapter 29) → Audit risk |
| PFA Granules | 3904.30.00.00 - "PFA Fluoropolymer, Primary Form" |
Misdeclare as "Standard Plastic" → Rate mismatch |
| Pre-cut PTFE Sheets | 3926.90.97.95 - "Plastic Articles, Semi-finished" |
Misdeclare as raw powder → Tariff error |
| Filled PTFE (e.g., Glass-filled) | 3904.21.00.00 (Generally) |
Check specific subheading for composites; usually still 3904.21 if PTFE base |
✅ 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| OEM Custom Compounds | Provide formula or generic description. Avoid disclosing proprietary formulas unless required. |
| Mixed Shipments (PTFE + Fittings) | Split the declaration. PTFE powder under 3904; Metal fittings under 7307/7318. Do not lump them. |
| Re-export from 3rd Country | If processed in Malaysia, ensure Substantial Transformation occurred. Apply for non-China origin CO to avoid US tariffs. |
| Sample Shipments | Even samples are subject to customs inspection. Mark as "Sample - Not for Resale" but still declare value accurately. |
🌍 V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification Requirements | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3904.21.00.00 |
40.3% (5.3% + 25% + 10%) | FDA Contact (for food grade) | Highest duty; strict origin checks. |
| 🇨🇳 China | 3904.21.00.00 |
5.0% | CNCA (if applicable) | Low tariff; easy import. |

📌 Conclusion:
- The US market is the most expensive for Chinese fluoropolymer imports due to the triple-layer tariff structure (Base + Section 301 + IEEPA).
- Europe and Japan offer more stable, lower tariff environments, making them attractive alternatives for US-bound supply chains (via re-export, though caution is advised on rules of origin).
📌 VI. Common Mistakes & Pitfall Guide (Blood & Tears Lessons)
❌ Mistake 1: Declaring "Fluoropolymer" as "Chemical Raw Material" (HS 2933/2934)
👉 Consequence: Incorrect classification → Penalty + Back Tax + Shipment Delay.
❌ Mistake 2: Ignoring the "Primary Form" requirement
👉 Consequence: If the powder is in pre-filled bags but clearly labeled for final product, customs may argue it is a "finished article" (HS 3926), changing the duty base or triggering additional scrutiny.
❌ Mistake 3: Assuming "Filled PTFE" falls under Rubber (Chapter 40)
👉 Consequence: Filled PTFE remains a plastic article (Chapter 39) unless it is a vulcanized elastomer (FKM/Viton). Misclassification leads to audit flags.
❌ Mistake 4: Under-declaring Value
👉 Consequence: High-value fluoropolymers attract CBP scrutiny. Undervaluation leads to severe fines and loss of import privileges.
✅ Correct Practice:
"PTFE Resin, PTFE, Primary Form, White Powder, 25kg HDPE Bag, FDA Compliant, Model XYZ, Made in China"
🎯 VII. Conclusion: Precise Classification Saves Millions!
🎯 Remember the Mantra:
🔹 "Primary Form is 3904, Filled is still 3904, Finished Parts are 3926/4016."
🔹 "US Tariff is 40.3%, Avoid if Possible or Optimize Supply Chain."
📌 Pro Tip:
If your fluoropolymer is originating from Vietnam, Thailand, or Malaysia, you may qualify for preferential tariffs (0-5%) under various FTAs, bypassing the US IEEPA/Section 301 duties.
Recommendation: Apply for an Advance Ruling (CBP Ruling Letter) before shipping to mitigate risk.

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
