🪫 Graphite Sheets & Carbon Fiber Products (石墨片与碳纤维制品)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 1. Product Definition & Classification: What Exactly is "Graphite Sheet"?

Graphite Sheets are versatile materials primarily used for heat dissipation (thermal management) in electronics, battery manufacturing, and industrial applications. In international trade, they are not a single uniform category. Their classification depends heavily on the raw material source (artificial vs. natural/surface-modified) and the final form/application (electrical vs. non-electrical).

⚠️ Key Distinction Point:
- If the sheet is made from artificial graphite or surface-modified spherical graphite and is in the form of plates/sheets for general use → It falls under Chapter 38 (Preparations based on graphite). - If the sheet is made from carbon fibers (non-electrical use, e.g., structural or shielding) → It falls under Chapter 68 (Articles of stone/mineral substances). - If the sheet is specifically designed as an electrode (e.g., for electrolysis or electrical brushes) → It falls under Chapter 85 (Electrical machinery/electrodes).

📦 2. HS Code Classification Details (2026 Latest Tariff Authority对照)

🔍 Key Reminder:
- Base Tariff: 0.0% for all categories listed. - Additional Tariff: 25.0% for all categories listed (likely due to US Section 301 or similar trade measures affecting Chinese-origin goods). - Total Tax: 25.0% across the board for these specific graphite/carbon items in this dataset. - Do not confuse "Graphite Sheets for Heat Dissipation" (often Ch 38) with "Graphite Electrodes" (Ch 85). The intended use determines the chapter.

💰 3. 2026 Latest Tariff Rate Breakdown (Detailed Tax Clauses)

✅ Applicable Country: United States (US) (Implied by 25% additional tariff structure common in 2024-2026 trade data)
✅ Origin: China (CN) (Inferred from 25% additional tariff pattern)
✅ Effective Time: Current (2025-2026)

🎯 1. 3801.10.50.10 & 3801.10.50.90 – Artificial Graphite Sheets/Films

📌 Explanation:
- These codes cover artificial graphite products. If your graphite sheet is made from synthetic graphite (e.g., SSG - Surface Modified Graphite), it falls here. - Note: Natural graphite sheets (if any) might fall under different headings, but the provided data focuses on artificial graphite for these two codes.

🎯 2. 6815.11.00.00 & 6815.19.00.00 – Carbon Fiber/Graphite Articles (Non-Electrical)

📌 Explanation:
- If the "graphite sheet" is actually a carbon fiber composite sheet used for structural or non-electrical shielding purposes, use these codes. - Key phrase: "for non-electrical uses". If it conducts electricity for a purpose other than electrodes, it still falls here unless it’s an electrode.

🎯 3. 8545.19.20.00 & 8545.90.40.00 – Carbon Electrodes (Electrical Uses)

📌 Explanation:
- If the graphite sheet is specifically an electrode (e.g., for battery testing, electrolysis, or welding), it must be declared under Chapter 85. - 8545.19.20.00 is for electrolytic purposes. - 8545.90.40.00 is for other electrical uses (e.g., carbon brushes, general electrical contacts).

🛠️ 4. Customs Clearance Practical Advice (Combat Pitfall Guide)

✅ 1. Documentation Checklist (Essential)

✅ 2. Declaration Strategy (Key Tips)

🔥 "Declare by Material & Use, Not Just 'Sheet'"

⚠️ Critical Note: All listed HS Codes in the provided data carry a 25.0% total tax. Therefore, while the tariff rate is the same, the classification accuracy is vital for: - Regulatory compliance (DOT, EPA, etc., may differ) - Potential future tariff changes (exclusions may apply to Ch 38 but not Ch 85, etc.) - Avoiding fines for misrepresentation of product nature.

✅ 3. Special Circumstances

🌍 5. Global Market Customs Comparison (2026 Latest)

📌 Conclusion:
- The 25% tariff is specific to the US market (based on the provided data).
- Accurate classification is essential not just for tax, but for regulatory compliance (e.g., electrical vs. non-electrical).
- Recommendation: For graphite sheets, clearly specify "Artificial Graphite" or "Carbon Fiber" and "Non-Electrical Use" or "Electrolytic/Electrical Use" in the commercial invoice.

📌 6. Common Errors & Pitfalls (Lessons Learned)

❌ Error 1: Declaring "Graphite Sheet" generically without specifying material type.
👉 Result: Customs may assign the highest duty rate or request extensive documentation.

❌ Error 2: Classifying Carbon Fiber sheets under 3801.10 (Graphite preparations) instead of 6815.19 (Carbon fibers).
👉 Result: While tax is same in this dataset, it’s a misclassification that can lead to audits.

❌ Error 3: Using 8545 codes for non-electrical graphite sheets.
👉 Result: Incorrect chapter; may trigger electrical safety inspections unnecessarily.

❌ Error 4: Ignoring the "Surface-Modified" distinction for artificial graphite.
👉 Result: Should use 3801.10.50.10 for surface-modified spherical graphite; using 3801.10.50.90 for generic artificial graphite is acceptable but less precise.

✅ Correct Practice:

"Artificial Graphite Heat Dissipation Sheet, Surface-Modified, Model XYZ, 100% Synthetic, For Thermal Management Only, No Electrical Conductivity Purpose"

🎯 7. Conclusion: Precise Classification Saves Time & Money!

🎯 Key Takeaway:

🔹 "Know Your Material: Artificial vs. Carbon Fiber vs. Electrode"
🔹 "25% Tax Applies to All, But Misclassification Risks Penalties"
🔹 "Declare Use Clearly: Thermal, Structural, or Electrolytic"

📌 Pro Tip:
- If your graphite sheet is not for electrical purposes, ensure your documentation explicitly states "Non-Electrical Use" to justify Ch 68 over Ch 85. - For artificial graphite products, use Ch 38 codes for precise classification. - Always pre-classify with a customs broker if the product’s use is ambiguous (e.g., a graphite sheet that conducts heat but also conducts electricity).

📣 Immediate Action:

📞 Contact a licensed customs broker
📄 Provide detailed product specs and intended use
✅ Apply for a binding tariff ruling if shipment value is high
🚀 Ensure smooth clearance, avoid delays, and optimize costs!
