Teflon Filled Granules

🧪 Teflon Filled Granules (PTFE Compounds)

🌐 HS Code Classification & Customs Clearance Guide | 2026 Tariff Analysis | Precision Clearance Strategy
📌 I. Product Definition: What Exactly Are "Teflon Filled Granules"?

"Teflon" is a generic trademark for Polytetrafluoroethylene (PTFE). "Filled granules" indicate that pure PTFE powder has been compounded with additives (such as graphite, carbon fiber, glass fiber, bronze powder, or silicone oil) to enhance mechanical strength, thermal conductivity, or wear resistance.

In international trade, these materials are classified strictly based on their chemical composition and physical form (primary forms). They are not finished products, nor are they simple mixtures of different polymers unless specified otherwise.

⚠️ Critical Distinction:
- If the product is pure PTFE (unfilled) in granular form: It falls under 3904.61.
- If the product is PTFE blended with other primary plastics: It falls under 3903.90.
- According to your provided data, the specific items are classified under Acrylic Polymers (3907.61) and Other Polyethers/Epoxides (3907.29). Note: This classification in the provided data appears technically unusual for standard PTFE, as PTFE is typically HS 3904. However, strictly following the provided <DATA> constraints, we must explain the rationale for the provided HS codes or identify if the description "Teflon Filled Granules" in the user prompt might be a mislabel for Acrylics/Polyethers in the specific context of the <DATA>. However, looking closely at <DATA>, the HS codes provided are 3907.61.00.50 (Acrylics) and 3907.29.00.00 (Other Polyethers). PTFE is NOT an acrylic or a polyether.*

Correction/Refinement: The user prompt asks to explain why "Teflon Filled Granules" are classified into the <DATA>. There is a fundamental mismatch. Teflon (PTFE) belongs to HS Chapter 39, Heading 3904. The data provided (3907.61 and 3907.29) covers Acrylics and Polyethers/Epoxides.

Hypothesis: The user might have pasted the wrong data or the wrong product name. However, as an AI instructed to "explain why it is classified into <DATA>", I must address the discrepancy professionally. If the granules are actually Acrylics (e.g., PMMA filled with Teflon-like lubricants) or Polyethers, the classification holds. If they are truly PTFE, the provided HS codes are incorrect.

Strategy: I will provide the analysis for the provided HS codes assuming the product description in <DATA> is the ground truth for the classification exercise, while adding a strong warning that "Teflon (PTFE)" usually does not fall under these codes. I will treat the <DATA> entries as the "Correct Classification" for the sake of the exercise, explaining the legal definitions of those HS codes.

📦 II. HS Code Classification Details (Based on Provided Data)

The provided data lists two specific HS Codes with corresponding taxes. We will analyze them based on the official Harmonized System definitions.

🔍 Critical Note on "Teflon" vs. Data:
- True PTFE (Polytetrafluoroethylene) typically falls under HS 3904.61.
- The provided HS codes 3907.61 and 3907.29 refer to Acrylics and Polyethers, respectively.
- Recommendation: If your product is truly Teflon (PTFE), please verify the HS Code 3904.61. The data provided may be for a different product (e.g., Acrylic Granules or Polyether Resins).
- For the purpose of this report, we will explain the taxes and clearance for the provided HS codes as requested, but highlight the potential classification error.

💰 III. 2026 Tariff Rate Breakdown (Based on Provided Data)

✅ Applicable Country: United States (US)
✅ Origin: China (CN) (Implied by "Additional Tariffs" context typical in such queries)
✅ Effective Date: Current 2026 Rates (Section 301 + Base Rates)

🎯 1. HS Code 3907.61.00.50 — Acrylic Polymers in Primary Forms

📌 Explanation:
- 6.5% Base: The standard duty for acrylic polymers (PMMA, etc.).
- 25% Additional: The 25% tariff imposed on Chapter 39 products from China under Section 301.
- Total: 31.5%. This is a significant cost factor.

🎯 2. HS Code 3907.29.00.00 — Other Polyethers & Epoxide Resins

📌 Explanation:
- 6.5% Base: The standard duty for polyethers (like PEO) and epoxy resins.
- 25% Additional: The 25% tariff imposed on Chapter 39 products from China under Section 301.
- Total: 31.5%.

✅ 1. Documentation Checklist (Must-Haves)

✅ 2. Declaration Tips (Key Strategies)

🔥 "Accuracy is Key: Match Name to Code!"

📌 Warning:
If you are importing Teflon (PTFE), please double-check your HS Code. PTFE is NOT an Acrylic (3907) nor a Polyether (3907). It is a Fluoropolymer (3904).
- If you use the provided HS codes for PTFE, you risk Customs Audits.
- Correct HS for PTFE Granules: 3904.61.00.00 (Polytetrafluoroethylene in primary forms).
- Tax for PTFE (3904.61): Typically Base 5.3% + 25% = 30.3% (or similar depending on exact subheading).

✅ 3. Special Handling for "Filled" Granules

• Fillers: If the granules contain graphite, carbon, or glass, ensure the base polymer is declared.
• If base is Acrylic → 3907.61
• If base is Polyether → 3907.29
• If base is PTFE → 3904.61
• Mixtures: If it is a blend of two different polymers (e.g., 50% Acrylic + 50% PTFE), it may be classified as the polymer that gives the material its essential character. This is complex and may require a Binding Ruling.

🌍 V. Global Market Comparison (2026)

📌 Conclusion for USA:
- The provided data shows 31.5% for the listed codes.
- If you are importing PTFE, expect ~30.3% under HS 3904.61.
- Do not misclassify PTFE as Acrylic/Polyether to save time; the risk of penalties is high.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Calling PTFE "Teflon" on the invoice without HS code context.
👉 Result: Customs may delay for classification. Always use chemical name (Polytetrafluoroethylene) and correct HS.

❌ Mistake 2: Using HS 3907 for PTFE to match a "similar" code.
👉 Result: Misdeclaration. If audited, you will owe back taxes + penalties + interest. PTFE (3904) and Acrylic (3907) are chemically distinct.

❌ Mistake 3: Ignoring the "Filled" aspect.
👉 Result: If fillers exceed certain percentages, the product might be classified as a compound or even a manufactured part rather than a primary polymer. Ensure the granules are in "primary forms" (powder/granules) and not pre-molded parts.

✅ Correct Practice:

"Polytetrafluoroethylene (PTFE) Granules, Filled with 15% Graphite, for Industrial Molding, Primary Form, HS 3904.61.00.00"

🎯 VII. Conclusion: Precision in Classification Saves Money

🎯 Key Takeaway:

🔹 "Teflon" (PTFE) is HS 3904, NOT 3907.
🔹 The provided data (3907.61 and 3907.29) applies to Acrylics and Polyethers.
🔹 If your product is truly Teflon, please verify your HS Code with a customs broker. Using the wrong HS code leads to 31.5% tax on the wrong item and potential legal issues.
🔹 If your product is Acrylic or Polyether granules, the 31.5% total tax (6.5% Base + 25% Additional) is correct for US imports from China.

📌 Pro Tip:

Request a Binding Tariff Ruling from US Customs and Border Protection (CBP) if you are unsure. It costs money but provides legal certainty and protects you from future audits.

📣 Action Plan:
1. Confirm Chemical Composition: Is it PTFE, Acrylic, or Polyether?
2. Match HS Code:
- PTFE → 3904.61
- Acrylic → 3907.61
- Polyether → 3907.29
3. Prepare Documents: Invoice, MSDS, CO, Spec Sheet.
4. Calculate Duty: CIF Value × 31.5% (for 3907 codes) or ~30.3% (for 3904 PTFE).
