U.S. imports of Cobalt Mattes, Unwrought Cobalt, and Cobalt Powders (HS 810520) totaled $43.1M in August 2026, imported from 20 countries.
Importers of Cobalt Mattes, Unwrought Cobalt, and Cobalt Powders paid $47K in duties in August 2026, an average duty rate of 0.11% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Cobalt Mattes, Unwrought Cobalt, and Cobalt Powders imports of $43.1M in August 2026 ran 15% below the year-to-date monthly average of $50.5M.
Last updated: August 2026 dataCobalt's critical-mineral status in battery cathode materials, superalloys, and hard-metal tooling makes this heading commercially significant for the electric-vehicle and aerospace supply chains. The US schedule subdivides the heading into unwrought cobalt alloys (8105203000), unwrought cobalt excluding alloys including powders (8105206000), and other cobalt mattes and intermediate metallurgical products (8105209000). Canada leads US import supply, followed by Indonesia and Norway — a supplier mix that reflects both primary mining output and intermediate refining capacity. Given cobalt's designation as a critical mineral, importers should monitor any evolving Section 232 or supply-security policy developments.

Cobalt mattes are intermediate smelter products — partially processed sulfide or oxide concentrates — that have not yet been refined to metal form. They classify under 8105209000 alongside other intermediate metallurgical products. Unwrought cobalt metal (including alloys and powders) classifies under 8105203000 or 8105206000 depending on whether it is an alloy. The distinction requires review of the product's chemical composition and processing stage documentation.
Unwrought cobalt alloys (8105203000) and unwrought cobalt excluding alloys (8105206000) may carry different duty rates and could have different trade-remedy exposure. An alloy is generally defined as a metallic material intentionally containing other elements to modify properties; importers should obtain certified composition analysis to support the correct line selection and avoid potential misclassification penalties.
