HS Code for Graphite blocks

Graphite blocks are classified under HS code 3801.90. This classification is governed by the provisions of Chapter 38, which encompasses miscellaneous chemical products. Heading 3801 specifically covers artificial graphite, colloidal or semi-colloidal graphite, and preparations based on graphite or other carbon in the form of pastes, blocks, plates, or other semi-manufactures. The determination for 3801.90 is based on the fact that these blocks are typically artificial graphite or carbon-based preparations intended for further industrial processing. Unlike natural graphite, artificial graphite is produced through high-temperature treatment of petroleum coke or coal tar pitch. When these materials are shaped into blocks but have not yet been machined into specific finished components (such as electrical brushes or mechanical seals), they are treated as semi-manufactures under this subheading. The classification ensures that raw or semi-finished industrial materials are distinguished from both the raw mineral ore and the final consumer or industrial article.

Products Included

• Artificial graphite blocks for EDM (Electrical Discharge Machining)
• Carbon-graphite blocks for mechanical seals
• Semi-finished synthetic graphite plates
• Graphite-based pastes in block form
• Extruded or isostatically pressed graphite blocks

Common Misclassification

Graphite blocks are often misclassified under HS code 2504.10, which is reserved for natural graphite in powder or flakes. If the block is composed of natural graphite that has been bonded or processed into a shape, it generally moves to Chapter 38 or 68. Another common error is using HS code 6815.19, which covers finished articles of graphite. If the block has been precision-machined into a specific part, it belongs in 6815. Finally, if the block is intended for electrical use as an electrode, it should be classified under 8545.11 or 8545.19 depending on the application.

FAQ

What is the HS code for artificial graphite blocks?

Artificial graphite blocks are classified under HS code 3801.90 as semi-manufactures.

How do I distinguish between blocks in 3801 and 6815?

HS code 3801 is for semi-manufactures like raw blocks or plates, while 6815 is for finished articles that have been machined into specific non-electrical shapes.
