HS Code for Synthetic graphite

Synthetic graphite is classified under HS code 3801.10 because it is a manufactured product resulting from the high-temperature treatment of carbonaceous materials, such as petroleum coke, coal tar pitch, or anthracite coal. Unlike natural graphite, which is a mineral extracted from the earth and classified in Chapter 25, synthetic graphite is considered a chemical product of Chapter 38. The classification process follows General Interpretative Rule 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Heading 3801 specifically covers artificial graphite, colloidal or semi-colloidal graphite, and preparations based on graphite. Subheading 3801.10 is reserved for the primary artificial form. The material must exhibit the crystalline structure of graphite but be produced through industrial processes like graphitization in electric furnaces at temperatures exceeding 2,500 degrees Celsius. This distinction is critical because the physical properties, such as high purity, consistent crystallinity, and low ash content, differ significantly from the natural mineral. The classification also covers synthetic graphite in the form of powder, flakes, or blocks, provided they have not been further worked into specific parts or articles.

Products Included

• Electro-graphite for electrodes
• Nuclear grade synthetic graphite
• Artificial graphite powder and grains
• Graphite blocks and plates (unworked)
• Synthetic graphite flakes

Common Misclassification

Synthetic graphite is frequently confused with natural graphite, which falls under HS code 2504. While they share chemical similarities, the origin (mined vs. manufactured) is the deciding factor. It is also often misclassified with 3801.20, which is specifically for colloidal or semi-colloidal graphite, or 3801.30, which covers carbonaceous pastes for electrodes. Additionally, if the graphite has been shaped into specific machine parts, it may fall under 8545 for electrical carbon or 6815 for non-electrical carbon articles.

FAQ

What is the HS code for synthetic graphite?

The primary HS code for synthetic (artificial) graphite is 3801.10.

How do I distinguish between natural and synthetic graphite for customs?

Natural graphite (2504) is a mineral product, while synthetic graphite (3801.10) is produced via high-temperature heat treatment of carbon precursors. Lab analysis of ash content and crystal structure often confirms the origin.
