Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If presented as part of a complete cutting tool
Assembled tool inserts with holders classify as interchangeable tools of base metal, shifting from Chapter 81 raw material articles.
If for use in plows or cultivators
Tungsten articles designed specifically for agricultural machinery end-use fall under parts of harvesting machines.
If in millstone or grinding wheel form
Tungsten shapes for grinding applications are classified by function in Chapter 68 rather than material composition.

Import Tips & Compliance
• Verify tungsten content exceeds 99% by weight via certified assay reports to confirm classification under Chapter 81
• Provide mill test certificates documenting composition to avoid misclassification as alloys under general metal headings
• Ensure proper labeling of hazardous properties if coated, as tungsten carbide dust poses inhalation risks during customs inspection
