✨ Colloidal Graphite Paste (胶体石墨膏)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: Understanding "Graphite Paste"

Colloidal graphite paste is a specialized industrial lubricant and anti-seize compound. It consists of finely divided graphite particles suspended in a carrier medium (such as water, oil, or chemical solvents). Unlike dry graphite powder, this paste offers superior adhesion and heat resistance, making it critical for high-temperature machinery, threaded fittings, and electrical contacts.

In international trade, its classification depends heavily on material composition vs. industrial preparation:

1. Graphite Preparations (3801): Products formulated as pastes, blocks, or plates based on graphite or other carbon, specifically designed for industrial use (e.g., lubrication, mold release). This is the most accurate classification for prepared pastes.
2. Chemical Products (3819): Lubricating preparations not elsewhere specified. This may apply if the product is viewed primarily as a generic lubricant rather than a graphite-specific preparation.
3. Raw Graphite Materials (2604/2600): If the product is classified primarily by its base raw material (crude graphite) rather than its formulation as a processed paste.

⚠️ Key Distinction Point:
- If the product is a paste/preparation with a carrier medium for industrial application → 3801.90.00.00
- If it is a generic lubricant without specific graphite formulation emphasis → 3819.00
- If it is raw/graphitic material not processed into a paste preparation → 2604.00

📦 II. HS Code Classification Details (Authoritative 2026 Tariff Mapping)

🔍 Critical Reminder:
- The vast majority of commercial "Colloidal Graphite Paste" used as a lubricant or anti-seize agent is classified under 3801.90.00.00 because it is a preparation based on graphite. - Classifying under 2604.00 is risky unless the product is truly raw, unprocessed graphite. - Classifying under 3819.00 is acceptable only if the product is a mixed lubricant not specifically defined as a "graphite preparation."

💰 III. 2026 Latest Tariff Rate Details (Including Additional Duties)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: Current trade rules (Section 301 & IEEPA)

🎯 1. 3801.90.00.00 —— Other Graphite Preparations (Colloidal/Semi-Colloidal)

📌 Explanation:
- The base tariff for HS Code 3801 is generally 0%.
- However, products from China are subject to a 25% additional tariff under Section 301 of the Trade Act.
- Total Effective Rate: 25%. This is a significant cost factor that must be factored into pricing strategies.

🎯 2. 3819.00 —— Lubricating Preparations (NOS)

📌 Note:
- The tax information for HS Code 3819.00 was not successfully retrieved in the system.
- This indicates potential classification ambiguity or data gaps.
- Recommendation: Avoid using 3819.00 for customs clearance unless you have confirmed the tax rate with a licensed customs broker.

🎯 3. 2604.00 —— Graphite and Other Carbonaceous Materials

📌 Note:
- Similar to 3819.00, tax data for 2604.00 is unavailable.
- Classifying a paste as raw graphite (2604) is likely incorrect and could trigger audits.

✅ 1. Document Checklist (Essential)

✅ 2. Declaration Tips (Key Mnemonics)

🔥 "Specify 'Preparation', Not 'Raw Material'!"

✅ 3. Special Considerations

🌍 V. Global Market Comparison (2026 Update)

📌 Conclusion:
- The US imposes a 25% additional tariff on graphite preparations from China.
- EU/UK/Japan have much lower or standard tariffs, making them more cost-effective markets for Chinese graphite paste.
- Risk Alert: Misclassifying as raw graphite (2604) in the US could lead to severe penalties and back-taxes.

📌 VI. Common Errors & Pitfall Guide (Lessons Learned)

❌ Error 1: Declaring "Graphite Paste" as "Graphite Powder" (HS 2604)
👉 Consequence: Misclassification. Customs may reject the entry or impose fines. The 25% tariff still applies, but you risk additional penalties.

❌ Error 2: Ignoring the "Carrier Medium" in the description
👉 Consequence: Customs may question whether it is a "preparation" (3801) or a "chemical product" (3819). Ambiguity leads to delays.

❌ Error 3: Assuming all graphite products have the same tax rate
👉 Consequence: Tax Data Errors. Codes 3819 and 2604 had retrieval errors. Relying on them without verification is dangerous.

✅ Correct Approach:

"Colloidal Graphite Paste, Artificial, in Carrier Medium, for Industrial Lubrication/Anti-Seize Use, HS 3801.90.00.00"

🎯 VII. Conclusion: Professional Declaration for Smooth Clearance

🎯 Remember This Rule:

🔹 "Paste = Preparation (3801)"
🔹 "Raw = Material (2604)"
🔹 "US Tariff = 25% on 3801"
🔹 "Verify 3819/2604 Tax Data"

📌 Pro Tip:

If your product is high-temperature resistant or electrically conductive, specify this in the description to support the "preparation" classification under 3801.
For US shipments, budget for the 25% additional tariff. Consider transshipment or origin switching if volume is high and margins are tight.

📣 Immediate Action:

📞 Contact a licensed customs broker to confirm the exact composition and carrier medium.
📄 Prepare MSDS and detailed product specifications.
🚀 Ensure accurate HS Code declaration to avoid customs holds and financial losses.
