HS Code for Waste tungsten

Waste tungsten is classified under HS code 8101.97. Chapter 81 of the Harmonized System covers "Other base metals; cermets; articles thereof," and heading 8101 is specifically assigned to tungsten (wolfram). The classification logic follows the structure of the chapter where unwrought forms and powders are listed first, followed by intermediate forms, and finally waste and scrap. Subheading 8101.97 is designated for tungsten waste and scrap. This classification requires that the material be metallic and fit only for the recovery of tungsten or for use in chemical manufacturing. Tungsten is often found in the form of tungsten carbide, which is a cermet. While pure tungsten scrap is straightforward, scrap consisting of tungsten carbide (a mixture of tungsten and carbon) is also typically classified here or under 8113.00 depending on the binder. However, for standard metallic tungsten scrap, 8101.97 is the internationally recognized code. The high density and melting point of tungsten make its scrap highly recyclable and strictly regulated in international trade.

Products Included

• Broken tungsten filaments from lamps or heaters
• Tungsten electrode stubs from TIG welding
• Tungsten carbide tool inserts (worn or broken)
• Tungsten shavings and turnings from precision machining
• Heavy metal alloy scrap where tungsten is the primary component

Common Misclassification

Waste tungsten is often misclassified under 8101.10, which is the code for tungsten powders. While some scrap may be finely ground, 8101.10 is for primary production powders. Another common error is using 2849.90 for tungsten carbide; while 2849.90 covers the chemical compound, the scrap of tools made from it is generally treated as metal scrap. Additionally, tungsten ores are classified under 2611.00, which should never be used for processed metallic waste.

FAQ

What is the HS code for Waste tungsten?

The HS code for tungsten waste and scrap is 8101.97.

Is tungsten sludge classified under this code?

If the sludge is a chemical residue or ash, it may fall under 2620.99. However, if it is a collection of metallic particles from grinding, it may qualify for 8101.97.
