8105.20 - Cobalt mattes and other intermediate products of cobalt metallurgy; unwrought cobalt; powders:

This HTS category, 8105.20, encompasses cobalt mattes and other intermediate products derived from the smelting and refining processes of cobalt. It specifically includes unwrought cobalt in its raw, unworked state, as well as cobalt powders. These materials represent the refined output of cobalt metallurgy before being further processed into finished articles.

It is important to distinguish this category from its siblings. Unlike 8105.30.00.00, which is reserved for waste and scrap materials containing cobalt, this section focuses on primary, manufactured cobalt intermediates and unwrought forms. Category 8105.90.00.00, "Other," serves as a residual category for any cobalt-containing materials not specifically addressed by the other headings within 8105.

Within this broad classification, further subdivisions exist. The primary distinction is between unwrought cobalt, which forms a significant portion of this heading, and other products not explicitly detailed. This allows for a more precise classification of the various forms and stages of cobalt processing.
