8105.90.00.00 - Other

This category, HTS Code 8105.90.00.00, encompasses "Other" articles of cobalt not specifically classified under other subheadings within heading 8105. This residual category serves to capture a broad range of finished or semi-finished cobalt products that do not fit into the more specific classifications for cobalt mattes, unwrought cobalt, powders, or waste and scrap. Examples include manufactured articles such as cobalt alloys in specific shapes (e.g., wires, bars, rods, sheets, plates) that are not considered unwrought, as well as articles that have undergone further processing beyond simple metallurgy.

It is crucial to distinguish this category from its siblings. HTS 8105.20 covers intermediate products like cobalt mattes, as well as unwrought cobalt in its primary metallic form and cobalt in powder form. HTS 8105.30.00.00 is exclusively for waste and scrap materials of cobalt, which are typically destined for recycling. Therefore, 8105.90.00.00 is reserved for items that are no longer in their raw or intermediary metallurgical state but have not been specifically detailed elsewhere within the cobalt provisions of the tariff.

As this is a leaf node, there are no further subcategories within 8105.90.00.00. Classification within this heading relies on a thorough examination of the cobalt article's physical form, the extent of its processing, and its intended use to ensure it is not classifiable under the more specific subheadings of 8105.20 or 8105.30.00.00.
