Cobalt Mining Residue Scrap
Cobalt mining residue scrap consists of intermediate waste from copper-cobalt mining flotation processes, containing cobalt concentrates destined for further metallurgical recovery. This material qualifies as waste and scrap under tariff item 8105.30.00 because it is not directly usable as cobalt metal and requires additional processing. The cobalt content is the primary value driver, making it classifiable under the cobalt waste and scrap heading.

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 material is a matte or other intermediate product of cobalt metallurgy, not waste
Intermediate products of cobalt metallurgy are classified separately from waste and scrap.
If the material is processed into a usable article, such as cobalt metal or alloy
Articles of cobalt, other than waste and scrap, fall under this alternative heading.
If the material is a natural mineral ore, not a waste product from mining
Cobalt ores and concentrates are classified in Chapter 26, not as waste and scrap.

Import Tips & Compliance
• Ensure the material is genuinely waste or scrap, not a usable intermediate product, by providing a certificate of analysis showing cobalt content and a description of the recovery process
• Be aware that CBSA may require proof of origin to determine eligibility for preferential tariff treatments under free trade agreements
• Verify that the material is not contaminated with hazardous substances, as this may trigger additional environmental regulations
