Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the tungsten content is below the minimum for ferro-tungsten and it does not meet ferro-silico-tungsten specifications
Other ferro-alloys not elsewhere specified may apply if the composition falls outside the defined ferro-tungsten or ferro-silico-tungsten categories.

Import Tips & Compliance
• Ensure the alloy composition (silicon and tungsten percentages) is clearly documented on the commercial invoice to support classification under 7202.80.00
• Provide a certificate of analysis from the supplier to verify the tungsten and silicon content
• Be aware that anti-dumping or countervailing duties may apply depending on the country of origin; check the CBSA's measures in force
