Rhenium Superalloy Master Ingot Segments
These segmented ingots are high-purity rhenium (over 99%) used as master alloy additions in nickel superalloys for jet engine components. They are classified as articles of rhenium under this tariff item because they are not yet alloyed and retain the character of the base metal. The segmentation facilitates precise weighing and melting in superalloy production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the ingots are considered waste and scrap
If the ingots are defective or not usable as master alloy additions, they may be classified as rhenium waste and scrap under this alternative.
If the ingots are already alloyed with nickel
If the rhenium is combined with nickel to form a master alloy, the product would fall under nickel alloys instead of rhenium articles.

Import Tips & Compliance
• Ensure the ingots are accompanied by a certificate of analysis confirming rhenium purity exceeds 99% to support classification under this item
• Declare the goods as 'rhenium articles' and be prepared to provide technical specifications if requested by CBSA
• Verify whether any anti-dumping or countervailing duties apply to rhenium products from your country of origin
