HS Code for Carbon blocks

Carbon blocks are classified under HS code 3801.90. This classification falls under 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. Subheading 3801.90 is the residual category for carbon-based preparations that are presented in bulk semi-manufactured forms. These blocks are typically used as raw materials for further machining into electrodes, furnace linings, or mechanical parts. The classification is determined by the fact that the product is a chemical preparation of carbon in a solid, semi-finished state, rather than a finished article or a specific electrical component.

Products Included

• Artificial graphite blocks for industrial use
• Carbon-based refractory blocks
• Semi-manufactured carbon plates for mechanical seals
• Carbon blocks intended for electrode production
• Carbonaceous pastes in block form

Common Misclassification

A frequent misclassification occurs with HS code 8545.11 or 8545.19, which covers carbon electrodes. If the carbon block has already been shaped, threaded, or fitted for use as an electrode, it must be classified under 8545. However, if it is a plain block requiring further processing, 3801.90 is correct. Another error is using 6815.10, which covers non-electrical articles of graphite or other carbon; this is only for finished articles that are not semi-manufactures or chemical preparations.

FAQ

What is the HS code for carbon blocks?

The HS code for carbon blocks in semi-manufactured form is 3801.90.

When should I use HS code 8545 instead of 3801.90?

Use HS code 8545 if the carbon block has been specifically manufactured or machined into an electrical component, such as an electrode, brush, or battery carbon.
