⚫️ Surface-Modified Spherical Graphite (Surface-Modified Spherical Graphite)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Surface-Modified Spherical Graphite"?
Surface-modified spherical graphite is a high-performance carbon material widely used in lithium-ion batteries, refractory materials, and lubricants. It is produced by processing natural or synthetic graphite into a spherical shape and then applying surface modifiers to enhance compatibility with resins, binders, or electrolytes.
In international trade, it is classified based on its material nature (carbon/graphite), physical form (spherical/powder), and degree of processing (modified vs. raw). Misclassification often leads to significant tariff discrepancies and customs delays.
⚠️ Key Distinction Point:
- If the product is a natural graphite processed into spherical particles → Often falls under 2504.10.50.00 (Natural Graphite).
- If the product is a specific carbon article (e.g., electrodes, specific shapes) → Falls under 6815.11.00.00.
- If it is a general carbon/graphite article not specified elsewhere → Falls under 6815.19.00.00.
- If it is considered a basic form of carbon (elemental) → Falls under 2803.00.00.10.
- If it is surface-modified and considered a distinct chemical/physical entity → May fall under 3801.10.50.10 (Artificial Graphite/Prepared Graphite).
📦 II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
| HS Code | Product Description | Application Scenario | Processing Degree |
|---|---|---|---|
3801.10.50.10 |
Surface-modified spherical graphite; material is graphite, form is spherical, consistent with surface-modified graphite characteristics | High-end battery anodes, specialty lubricants, modified carbon composites | ✅ Modified (Chemical/Physical Surface Treatment) |
6815.11.00.00 |
Surface-modified spherical graphite; material is graphite, form is spherical, classified as non-electrical carbon articles | General industrial carbon parts, non-conductive graphite seals, generic carbon blocks | ✅ Non-electrical Carbon Article |
6815.19.00.00 |
Surface-modified spherical graphite; material is graphite, form is primary state, fits classification of other graphite articles | Bulk graphite powder, less specific carbon goods, general industrial fillers | ✅ Other Graphite Article |
2504.10.50.00 |
Surface-modified spherical graphite; material is graphite, form is spherical (powder/granular), belongs to natural graphite processing forms | Battery anode precursor, refractory additives, traditional graphite uses | ✅ Natural Graphite Processed |
2803.00.00.10 |
Surface-modified spherical graphite; material is special form of carbon (graphite), fits classification of carbon and its derivatives | Elemental carbon products, raw carbon forms, basic carbon materials | ✅ Elemental Carbon Form |
🔍 Key Reminder:
- Surface Modification Matters: If the graphite has undergone significant surface treatment (e.g., acid coating, coating with metal oxides, or polymer wrapping), 3801.10.50.10 is a strong candidate because it reflects "prepared" or "modified" graphite.
- Natural vs. Synthetic: If it is natural graphite that is merely spheroidized (physical shaping) without chemical modification, 2504.10.50.00 is more appropriate.
- Non-Electrical Use: Items under 6815 are explicitly for non-electrical uses. If the graphite is conductive and used in electrodes, do not use 6815.

| ✅ Packing List | ✔️ | Detail net/gross weight, number of packages. |
| ✅ Certificate of Origin (CO) | ✔️ | Required for origin determination (China-origin triggers 35% tariff). |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 “Nature Defines Code, Modification Changes It, Use Determines Eligibility!”
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Natural graphite, spheroidized, slight coating | 2504.10.50.00 |
Misdeclare as 3801 → May delay for "chemical" review |
| Heavy surface modification (polymer/metal oxide) | 3801.10.50.10 |
Misdeclare as 2504 → Risk of "modified product" penalty |
| Used in batteries (conductive) | 2504.10.50.00 or 3801.10.50.10 |
Declare as 6815 → Incorrect (6815 is non-electrical) |
| Non-conductive graphite filler | 6815.19.00.00 |
Declare as 2504 → May be accepted, but less precise |
| Raw carbon powder | 2803.00.00.10 |
Rarely applicable for spherical graphite |
✅ 3. Special Situations Handling
| Situation | Handling Advice |
|---|---|
| Battery Anode Material | Typically classified under 2504.10.50.00 (if natural) or 3801.10.50.10 (if heavily modified). Ensure TDS confirms battery use. |
| Mixed Packages | If a package contains both graphite and additives, declare the principal material (graphite). |
| Origin Shifting | If graphite is mined in China but processed in Vietnam, ensure substantial transformation to claim non-Chinese origin. Otherwise, 35% still applies. |
| Pre-Import Ruling | Strongly recommend applying for a Binding Tariff Information (BTI) or Customs Ruling for large volumes to avoid post-entry audits. |

📌 VI. Common Errors & Pitfall Guide (Blood Lessons)
❌ Error 1: Declaring "Surface-Modified" graphite as "Natural Graphite" (2504) when it is heavily chemically treated.
👉 Consequence: Customs may reclassify to 3801 or impose penalties for misdeclaration.
❌ Error 2: Using HS Code 6815 for conductive graphite used in batteries.
👉 Consequence: Rejection or delay. 6815 is for non-electrical uses. Battery materials are electrical/conductive.
❌ Error 3: Failing to declare the degree of modification.
👉 Consequence: Customs may demand additional testing, causing 2-4 weeks delay.
❌ Error 4: Ignoring the IEEPA 10% tax.
👉 Consequence: Underpayment of duties → Fines and Back Taxes.
✅ Correct Practice:
"Surface-Modified Spherical Graphite, Natural Origin, Acid-Treated, D50 15μm, Purity >99.9%, for Lithium Battery Anode, Model XYZ"
🎯 VII. Conclusion: Professional Declaration, Time-Saving, Cost-Effective!

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
