Tungsten Heavy Alloy Powder
Tungsten heavy alloy powder, a pre-alloyed mixture of tungsten with nickel and iron (typically 92-97% tungsten by weight), used for radiation shielding and balance weights. Under Canadian tariff classification, it falls under tariff item 8101.10.00 as a powder of tungsten, provided the tungsten content predominates by weight over each other metal as per Section XV Note 5.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is sintered or formed into solid articles
Sintered tungsten products, such as weights or shielding blocks, are classified as articles of tungsten rather than powders.
If the tungsten content is less than 99% and it is an alloy
Alloys of tungsten, where tungsten predominates by weight, fall under the 'other' subheading for tungsten articles.
If the powder is a carbide or a cermet
Tungsten carbides are classified in Chapter 28 as inorganic chemicals, not under base metal powders.

Import Tips & Compliance
• 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)
