Import Tips
• Ensure the tungsten content is at least 99% by weight to qualify as 'not alloyed' under Chapter 81 supplementary note 1; otherwise, it may be classified as an alloy under a different heading
• Provide a mill certificate or lab analysis to the CBSA to confirm composition
• If the powder is mixed with binders or other substances, verify it does not fall under Section XV Note 1 exclusions (e.g
• paints or inks)
