🏭 PTFE Filled Granules (Polytetrafluoroethylene)

🌐 HS Code Classification & Customs Clearance Guide | 2026 Tariff Analysis for US Imports from China

📌 One-Sentence Summary:
PTFE filled granules are raw polymeric materials used in molding and extrusion. Their classification hinges on whether they are classified under the specific PTFE chapter (3914) or the general Plastics chapter (3904/3926), with significant tariff implications due to US-China trade tensions (Section 301 & Section 122 tariffs).

📦 1. HS Code Classification Breakdown

Below are the valid HS Codes for PTFE Filled Granules based on the provided data. The choice depends on the specific physical form and regulatory interpretation of "filled" vs. "pure" resin.

⚠️ Key Observation:
- Highest Tax (40.8%): Codes starting with 3904.61.00 (specifically .10 and .90).
- Lowest Tax (22.8%): Code 3926.90.99.89 (classified as generic plastic articles).
- Middle Range: 3914 codes range from 35.0% to 38.9%.

💰 2. Detailed Tariff Analysis & Legal Basis

All tariffs listed assume imports from China to the United States.

🎯 A. The "Section 301" & "Section 122" Context

📉 Tax Optimization Insight:

• Code 3926.90.99.89 offers the lowest total duty (22.8%).
• Risk: Customs may challenge this if the product is strictly "PTFE Resin" (Ch 3914) rather than a "Plastic Article" (Ch 3926). Chapter 3926 is typically for finished articles or semi-finished goods, not raw resin. Misclassification here could lead to penalties.
• Code 3914.00.20.00 has 0% Base Duty, but still incurs 35% total due to 301/122 tariffs.
• Code 3904.61.00.10 and .90 have the highest total duty (40.8%) due to a higher base duty (5.8%).

🛠️ 3. Customs Clearance Recommendations

✅ 1. Documentation Requirements

To ensure smooth clearance and avoid misclassification penalties, provide: - Material Safety Data Sheet (MSDS): Confirming PTFE composition and any "fillers" (e.g., carbon, glass, bronze). - Technical Data Sheet: Clearly stating "Granular Form" and "Primary Polymer." - Bill of Lading & Commercial Invoice: Must explicitly state "Polytetrafluoroethylene (PTFE) Granules" and not generic "Plastic Pellets." - Country of Origin Certificate: Confirming China origin to apply correct 301/122 tariffs.

✅ 2. Classification Strategy

• If PTFE is >50% by weight: Prioritize Chapter 3914 (Specific to PTFE Resins).
• Compare 3914.00.60.00 (38.9%) vs. 3914.00.20.00 (35.0%).
• If the product is heavily filled (e.g., >50% filler by weight) and considered a composite material:
• Consult a customs broker on whether 3926.90.99.89 (22.8%) is defensible. Note: This is high-risk if the filler does not change the essential character from "resin" to "article."
• Avoid 3904.61 if possible: It carries the highest base duty (5.8%) and total duty (40.8%).

✅ 3. Warning: "Filled" Granules

• Definition: "Filled" means additives (like PTFE + Carbon or PTFE + Glass) are mixed with the resin.
• Customs Risk: If the filler is significant, the product may no longer be "PTFE Resin" (Ch 3914) but rather a "Plastic Compound" or "Article."
• Action: Provide a detailed material composition sheet showing the percentage of PTFE vs. filler. If the filler changes the essential character, 3926.90.99.89 might be the correct (and cheaper) classification. If it’s just minor additives, stick to Ch 3914.

📌 5. Common Pitfalls & Avoidance

🎯 Final Recommendation

1. For Cost Minimization: Investigate if 3926.90.99.89 (22.8%) is defensible based on filler content. If not, choose 3914.00.20.00 (35.0%) over 3904.61.00.10 (40.8%).
2. For Compliance: Ensure documentation clearly distinguishes between "Resin" (Ch 3914) and "Articles" (Ch 3926).
3. Budgeting: Prepare for 23% – 41% total landed duty cost on top of the product price.

🚀 Pro Tip: Apply for a US Customs Ruling (Pre-Ruling) before shipping to confirm the correct HS Code and avoid surprise duties.
