π Spherical Graphite Wear Resistant Material | HS Code, Tariffs & Clearing Guide 2026
π Product Definition & Classification: What is Spherical Graphite Wear Resistant Material?
Spherical Graphite Wear Resistant Material is a specialized industrial material derived from natural or synthetic graphite. It is processed into a spherical morphology to enhance packing density, flowability, and uniformity. Due to its high hardness, excellent lubricity, self-lubricating properties, and thermal stability, it is widely used in:
- Anti-wear coatings for machinery, pumps, and valves.
- Friction materials such as brake pads and clutch linings.
- Lubricants and lubricating additives in greases and oils.
- Mold release agents in high-temperature industrial applications.
- Sealants and gaskets where chemical resistance is required.
β οΈ Key Distinction:
- Raw Spherical Graphite (powder form, unbound) β Classified under Chapter 38 (Prepared Binders) or Chapter 25 (Mineral Products) depending on treatment.
- Finished Wear-Resistant Coating/Composition (mixed with binders, resins, or other additives) β Classified under Chapter 38 (Prepared Anti-Knock Preparations, Prepared Lubricants, etc.).
- Natural Graphite (unprocessed) β Classified under 2504.10.π Critical Classification Point:
- If the product is pure spherical graphite powder without binders β HS 2504.10.00
- If it is spherical graphite mixed with resins/binders for wear-resistant applications β HS 3813.00.00 or 3819.00.00 depending on formulation.

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
