Unwrought Ruthenium Ingot
Unwrought ruthenium ingots, cast from electrolytic refining with a purity of 99.95%, in rectangular or trapezoidal cross-sections. These ingots are classified as unwrought ruthenium under the 'other' subheading for iridium, osmium, and ruthenium, as they are not in powder form and are not specifically listed under other subheadings.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ruthenium is in powder form
Ruthenium powder is classified under a specific subheading for powders, not the 'other' unwrought category.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify that the ruthenium ingots are not alloyed with other platinum group metals in a way that would change classification; if iridium, osmium, palladium, rhodium, or ruthenium predominates by weight, the alloy is classified with that metal
• Keep documentation of the refining process and purity to present to the CBSA if requested
