🖌️ Colloidal Graphite Dispersions (Lubricants & Hydraulic Fluids)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 Part 1: Product Definition & Classification – Do You Really Understand "Colloidal Graphite Dispersions"?
Colloidal Graphite Dispersions are complex chemical preparations where ultra-fine graphite particles are suspended in a liquid medium (typically water, alcohol, or petroleum-based oils). They are primarily used as high-temperature lubricants, anti-friction coatings, or hydraulic fluid additives.
In international trade, classification depends heavily on the base ingredient and primary function:
- Lubricating Preparations (Heading 3819/3403): If the primary purpose is lubrication, anti-friction, or surface treatment, and it contains petroleum oils or specific chemical additives.
- Chemical Preparations (Heading 3824/3819): If it’s a specialized chemical mixture not primarily for lubrication but for other industrial processes.
- ⚠️ Key Distinction Note: The provided reference data explicitly links this product to HS Code 3403.19 and 3819.00, describing them as:
- "Lubricating preparations containing petroleum oils..."
- "Hydraulic fluids prepared with a base of petroleum oils..."
⚠️ Critical Clarification: - If the dispersion is water-based or non-petroleum-based, it might fall under different headings (e.g., 3824). - However, per the provided context, we strictly classify based on petroleum-oil-based lubricants/hydraulics. - Do not misclassify as pure chemicals (3824) if it’s marketed/labeled as a lubricant.
📦 Part 2: HS Code Classification Details (Based on Provided Data)
| HS Code | Product Description | Key Characteristics | Primary Use |
|---|---|---|---|
3403.19 |
Lubricating preparations containing petroleum oils (Other) | Contains petroleum oil base; not for textile/metal working specifically (covered in 3403.11/12/13) | General industrial lubrication, anti-friction |
3819.00 |
Hydraulic fluids prepared with a base of petroleum oils | Base is petroleum oil; used in hydraulic systems | Hydraulic system transmission, sometimes as lubricant |
🔍 Important Note from Data: - The description for 3403.19 mentions: "Colloidal graphite dispersions are often classified here as lubricants or anti-friction coatings when used for that purpose." - The description for 3819.00 mentions: "Colloidal graphite dispersions are sometimes classified under... hydraulic fluids depending on their specific formulation." - Both codes assume a petroleum oil base. If your product is not petroleum-based (e.g., synthetic or water-based), these codes may be incorrect, and you must consult additional chemical headings (like 3824).

🛠️ Part 4: Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Documentation Checklist (Essential)
| Document | Must Provide | Explanation |
|---|---|---|
| ✅ Material Safety Data Sheet (MSDS/SDS) | ✔️ | Critical for chemical/hazardous goods classification. Must specify base oil type (petroleum vs. synthetic). |
| ✅ Technical Data Sheet (TDS) | ✔️ | Shows concentration, viscosity, and intended use (lubricant vs. hydraulic fluid). |
| ✅ Product Photograph | ✔️ | Clear label showing brand, model, and active ingredients. |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Colloidal Graphite Dispersion, Lubricating Preparation" or "Hydraulic Fluid". |
| ✅ Composition Analysis | ✔️ | Breakdown of ingredients: % Graphite, % Petroleum Oil, % Additives. Proves petroleum base for 3403/3819. |
| ✅ Certificate of Origin | ✔️ | For potential FTZ or anti-dumping verification. |
✅ 2. Declaration Strategy (Key Rules)
🔥 “Base Defines Code, Use Defines Category, Label Matches Reality!”
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Petroleum-based, for lubrication | 3403.19 + "Lubricating preparation containing petroleum oils" |
Call it "Chemical Additive" → Risk of misclassification |
| Petroleum-based, for hydraulic systems | 3819.00 + "Hydraulic fluid based on petroleum oils" |
Call it "General Lubricant" → Might be audited |
| Water-based or Synthetic base | ❌ NOT 3403/3819 → Likely 3824 or 3403.90 |
Force-fit into 3403.19 → Customs penalty! |
| Graphite powder (dry) | ❌ NOT dispersion → 3824.99 or 3818.00 |
Declare as liquid dispersion → Weight/Volume mismatch |
✅ 3. Special Handling Notes
| Situation | Recommendation |
|---|---|
| Origin is China | Even though tax data is "Error", assume 25% Section 301 risk for 3403/3819. Confirm with US CBP via Advance Ruling. |
| Hazardous Material | Graphite dispersions may be non-hazardous, but check SDS for flash point (if petroleum-based). May require HAZMAT declaration. |
| Misclassification Risk | If you declare 3403.19 but the product is water-based, CBP may reject it. Always provide SDS. |
| Valuation | Ensure declared value includes packing, insurance, freight (CIF). Graphite dispersions are high-value chemicals. |

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
