Colloidal Graphite Paste

✍️ Colloidal Graphite Paste (Conductive Lubricant/Release Agent)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Colloidal Graphite Paste"?

Colloidal Graphite Paste is a specialized industrial lubricant and release agent. It consists of finely divided graphite suspended in a liquid carrier (often oil, water, or synthetic fluid). It is used to reduce friction, prevent seizing, and provide electrical conductivity in high-temperature or high-pressure environments.

In international trade, it falls under Chapter 34 (Mineral Fuels, Oils, Distillation Products; Bituminous Substances; Waxes). Specifically, it is classified as a Lubricating Preparation.

⚠️ Key Classification Distinction:
- Based on Lubricants: If the primary function is lubrication, anti-rust, or mold release, it is classified under Heading 3403.
- Exclusion Rule: Preparations containing ≥70% by weight of petroleum oils or oils from bituminous minerals are often excluded from this specific sub-heading and may fall elsewhere (e.g., Chapter 27 or different 3403 sub-headings depending on the country).
- Our Target: The provided HS Code 3403.91.50.00 applies to preparations based on lubricants that do not meet the ≥70% threshold or are specifically formulated for textile/leather/fur treatment or general lubrication where the base is not purely petroleum oil.

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

🔍 Critical Note on the Provided Data:
- The <DATA> block provides 3403.19.50.00 in the JSON hscode field but describes the content of 3403.91.50.00 in the text description.
- Consistency Check: The description "Preparations for the treatment of textile materials, leather, furskins or other materials" aligns with 3403.91 (Preparations for treatment of textile/leather) in many tariff schedules, whereas 3403.19 usually refers to "Other lubricating preparations containing ≥70% oil."
- Recommendation: For Colloidal Graphite Paste used as a lubricant/release agent, if it contains <70% petroleum oil, it is most accurately classified under 3403.91.50.00 (as per the detailed description provided). If it contains ≥70% petroleum oil, it would be 3403.19.50.00.
- Current Analysis Basis: We will proceed with 3403.91.50.00 as the primary classification for generic colloidal graphite paste (often water-based or low-oil content), but note the potential overlap.

✅ Applicable Country: United States (US)
✅ Country of Origin: China (CN)
✅ Effective Date: Current 2025/2026 Schedule

🎯 1. 3403.91.50.00 —— Lubricating Preparations (Graphite Paste, Low Oil Content)

📌 Explanation:
- Base Rate: Lubricating preparations under this sub-heading generally carry a 0% base duty under normal trade relations (NTR).
- No Section 301 Impact: Unlike electronics or steel, many chemical preparations and lubricants are exempt or have 0% additional tariffs under Section 301, depending on the specific formulation. The provided data confirms 0% total tax.
- Why 0%?: The duty-free status encourages industrial maintenance and manufacturing efficiency. However, this does not mean it is "free" to import—other regulatory fees (FDA, EPA, DOT) may apply.

⚠️ Warning for High-Oil Content:
If your graphite paste contains ≥70% petroleum oil, it might be classified under 3403.19.50.00. Check the provided data:
- 3403.19.50.00 also shows 0.0% total tax in the provided data.
- Result: Regardless of the oil content threshold, the total tax remains 0.0% according to the provided <DATA>.

🛠️ IV. Customs Clearance Practical Advice (Avoid Pitfalls)

✅ 1. Documentation Checklist (Must-Have)

✅ 2. Declaration Tips (Key Mantra)

🔥 "Describe by Function, Declare by Composition, Avoid Ambiguity!"

📌 Critical Point:
- Do NOT declare as "Graphite" (natural or synthetic), which is a mineral/chemical product.
- DO emphasize it is a "Preparation Based on Lubricants".
- Confirm Oil Content: If the paste is oil-heavy, declare ≥70%. If it is water/gel-based, declare <70%. This affects the sub-heading but not the total tax in this specific data set (both are 0%).

✅ 3. Special Cases

🌍 V. Global Market Comparison (2026)

📌 Conclusion:
- USA: Most favorable (0% duty).
- EU: Highest barrier is REACH registration, not tariff.
- Global: Tariffs are low, but regulatory compliance (SDS, FDA, REACH) is the real challenge.

📌 VI. Common Mistakes & Pitfalls

❌ Mistake 1: Declaring as "Graphite Powder" (HS 3801/3824)
👉 Consequence: Misclassification → Potential 6-10% duty + penalties.
👉 Fix: It is a paste/preparation, not a raw powder.

❌ Mistake 2: Ignoring Petroleum Oil Content
👉 Consequence: If ≥70% oil, should be 3403.19. If declared as 3403.91, may face audit.
👉 Fix: Provide formula to prove <70% or ≥70%.

❌ Mistake 3: Missing SDS for Chemical Shipments
👉 Consequence: Customs holds shipment for inspection → Delays.
👉 Fix: Always attach SDS.

🎯 VII. Conclusion: Professional Declaration Saves Time & Money

🎯 Remember the Mantra:

🔹 "It’s a Paste, Not Powder!"
🔹 "Check the Oil %: <70% or ≥70%, Both 0% Duty Here!"
🔹 "SDS is Your Best Friend for Chemicals!"

📌 Pro Tip:
If your graphite paste is used in food processing equipment, ensure it is NSF H1 Registered or FDA Compliant. This does not affect duty but is critical for clearance speed and product safety.
