Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If still in matte form before full reduction
Cobalt mattes have a specific heading before sponge stage.
If containing zirconium or other metals from ore processing
Zirconium-bearing materials stay in Chapter 26.
If further processed into tubes/pipes with fittings
Fabricated articles move to specific cobalt articles subheading.

Import Tips & Compliance
• Submit production process documentation to distinguish sponge from mattes
• Comply with battery material sourcing rules under Inflation Reduction Act if applicable
• Test for impurities that could reclassify as alloy under Chapter 81
