U.S. imports of cobalt oxide & hydroxide; commercial cobalt oxides (HS 282200) totaled $4.8M in April 2026, traded with 10 countries.
Importers of Cobalt Oxide & Hydroxide; Commercial Cobalt Oxides paid $6K in duties in April 2026 — an effective duty rate of 0.1% on $4.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Cobalt Oxide & Hydroxide; Commercial Cobalt Oxides imports of $4.8M in April 2026 ran 19% below the year-to-date monthly average of $5.9M.
Last updated: April 2026 dataCobalt oxides and hydroxides — including cobalt(II,III) oxide (cobalt tetroxide) under 2822000010 and other commercial cobalt oxides under 2822000090 — are critical battery-cathode precursors for lithium-ion chemistries used in electric vehicles and consumer electronics, as well as colorants in ceramics and glass. Finland and Belgium lead US imports, reflecting the role of European refining hubs that process cobalt from Central African ore into battery-grade intermediates. Supply-chain due diligence around cobalt sourcing has become a significant compliance consideration, with importers increasingly required to document mineral provenance under corporate ESG and conflict-minerals frameworks. The distinction between cobalt(II,III) oxide and other cobalt oxide forms matters for both technical specification and tariff-line reporting.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both countries host major cobalt refining and chemical processing operations that convert cobalt hydroxide and intermediate products — largely sourced from the Democratic Republic of Congo — into battery-grade cobalt oxides and salts. The value-added refining step, not primary mining, determines the country of origin for customs purposes, which is why European refiners appear as leading suppliers even though the underlying ore originates elsewhere.
Beyond standard customs entry documents, many US importers of cobalt oxides now require suppliers to provide chain-of-custody certifications, third-party audits, or compliance with frameworks such as the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals. While these are not yet mandatory US customs requirements, they are increasingly demanded by downstream customers in the EV and electronics sectors and may affect supplier qualification decisions.
