This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is in semi-manufactured forms such as plates or sheets
Semi-manufactured forms of iridium, osmium or ruthenium are classified separately from unwrought or powder forms.
If platinum predominates by weight over iridium and ruthenium
Alloys are classified with the platinum group metal that predominates by weight, per subheading note 3.

Import Tips & Compliance
• Ensure the powder meets the subheading note definition: 90% or more by weight must pass through a 0.5 mm sieve
• Declare the exact composition by weight of each platinum group metal to support classification
• Keep certificates of analysis from the supplier for CBSA verification
