HS Code for Tungsten carbide

Tungsten carbide is classified under HS code 2849.90. This classification falls within Chapter 28, which covers inorganic chemicals and precious metal compounds. Heading 2849 is specifically dedicated to carbides, whether or not they are chemically defined. Since 2849.10 is allocated to calcium carbide and 2849.20 to silicon carbide, tungsten carbide is categorized under the \"Other\" subheading, 2849.90. This code applies to the chemical compound itself (WC or W2C) in powder or granular form. The classification is strictly for the chemical substance; once the tungsten carbide is mixed with a metallic binder (like cobalt) to create \"cemented carbide\" or \"hard metal,\" the classification may shift depending on the state of the product. However, pure tungsten carbide powder, used as a precursor in the manufacturing of cutting tools, wear-resistant parts, and abrasives, remains under 2849.90. It is essential to verify that the product is not a prepared mixture, as that would move the classification to Chapter 38.

Products Included

• Pure tungsten carbide powder (WC)
• Ditungsten carbide (W2C)
• Tungsten carbide crystals
• Non-agglomerated tungsten carbide grains
• Chemically defined tungsten-carbon compounds

Common Misclassification

Tungsten carbide is often misclassified under HS code 3824.30, which covers non-agglomerated metal carbides mixed together or with metallic binders. If the tungsten carbide powder is pre-mixed with cobalt or nickel powder, it must go to 3824.30. Another common error is using HS code 8209.00, which is for plates, sticks, tips, and the like for tools, unmounted, of cermets (including sintered tungsten carbide). If the tungsten carbide has already been pressed and sintered into a specific shape like a drill bit tip, it is no longer a chemical under 2849 but a tool component under 8209. Additionally, tungsten ores are classified in 2611.00, not 2849.

FAQ

What is the HS code for tungsten carbide?

The HS code for chemically defined tungsten carbide in powder form is 2849.90.

Does the code change if the powder is mixed with cobalt?

Yes, if the tungsten carbide is mixed with a metallic binder like cobalt but not yet sintered, it is classified under HS code 3824.30.
