HTS heading 8105 is a broad product category for cobalt-related goods. It covers cobalt mattes and other intermediate products made during cobalt metallurgy, as well as unwrought cobalt, cobalt powders, and finished or semifinished articles made from cobalt. It also includes cobalt waste and scrap. The heading is a starting point, not the final classification.
To reach the correct 8-digit HTS code, first identify the product’s physical form, composition, and stage of manufacture. Subheadings generally distinguish between intermediate metallurgical products, unwrought metal, powders, articles, and waste or scrap; further detail may depend on the product’s type or material characteristics. Read the complete tariff description, including any legal notes, units of quantity, and statistical suffix language, and confirm that the code matches the imported condition of the goods.
What to check
- Describe the goods as imported: record the cobalt content, other materials, physical form, dimensions, and manufacturing stage.
- Separate primary cobalt forms—such as matte, intermediate products, unwrought metal, and powder—from finished or semifinished cobalt articles.
- Classify waste and scrap based on what the material is and how it is presented for recovery or recycling; do not assume all cobalt-containing leftovers belong in the same provision.
- Compare the full 8-digit descriptions and any applicable section, chapter, or heading notes rather than choosing a code from the heading title alone.
- Keep technical specifications, bills of materials, laboratory information, product drawings, and supplier documentation to support the classification; seek a customs broker or binding ruling when the product is composite or borderline.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
