Wrought Cobalt and Cobalt Articles imports of $6.6M in August 2026 ran 16% above the year-to-date monthly average of $5.7M.
Last updated: August 2026 dataMechanically worked cobalt — including rolled, extruded, forged, and machined forms — and finished cobalt articles not elsewhere specified enter under 8105900000, serving the superalloy, cutting-tool, and medical-implant industries. Canada and the United Kingdom are the primary US import sources, reflecting established aerospace and specialty-metals manufacturing bases, with France, China, and Germany also supplying. Because wrought cobalt articles often incorporate proprietary alloy compositions, importers should retain mill certifications and composition reports to support both classification and any downstream traceability requirements.

Classification follows the GRI hierarchy: if the article is a finished part for a specific machine or tool (e.g., a turbine blade or drill bit), it may classify under the chapter governing that end product rather than under Chapter 81. Cobalt articles under 810590 are residual — they apply when no more specific heading covers the finished article. A binding ruling request to CBP is advisable for high-value components where the classification is genuinely ambiguous.
Wrought cobalt has been mechanically worked after solidification — rolled, forged, extruded, or drawn — altering its internal grain structure. Castings that are simply poured into a mold and not subsequently mechanically worked remain 'unwrought' and would classify under 810520. The processing route documented in the manufacturer's production records is the key evidence for making this distinction.
