More Specific Codes
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 copper content is 94% or more by weight
Higher-purity copper turnings would fall under the residual item for other copper waste and scrap.
If the turnings are from brass alloys rather than refined copper
Brass turnings with copper below 94% are classified under the brass-specific item.
If the turnings come from spent anodes that are not alloyed
Spent anode-derived waste with copper below 94% is covered by this item.

Import Tips & Compliance
• Keep records of the machining process and a laboratory analysis confirming copper content below 94% by weight
• Separate turnings contaminated with oil or other substances, as this may affect classification or require additional environmental permits
• Consult the CBSA's D10 customs tariff classification advice service for binding rulings on borderline shipments
