Importers of Chromium Oxides and Hydroxides (Except Chromium Trioxide) paid $204K in duties in August 2026, an average duty rate of 18.06% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Chromium Oxides and Hydroxides (Except Chromium Trioxide) imports of $1.1M in August 2026 ran 44% below the year-to-date monthly average of $2.0M.
Last updated: August 2026 dataTrivalent chromium sesquioxide (Cr₂O₃) is the commercially dominant product in this heading, widely used as a green pigment in ceramics, glass, and refractory bricks, and as a polishing compound for precision optics and metals. Germany leads US supply, followed by China and India. Unlike the hexavalent chromium trioxide of heading 281910, the trivalent compounds here carry a significantly lower toxicological profile, though importers should still confirm chemical identity and purity grade to support correct classification and end-use compliance.

The primary end uses are refractory applications (where Cr₂O₃ improves slag resistance in furnace linings), ceramic and glass colorants (producing stable green hues), and metallurgical polishing compounds. Specialty chemical and catalyst manufacturers also consume smaller volumes. Germany's prominence as a supplier reflects its advanced specialty chemicals and refractory materials industry.
A certificate of analysis specifying the oxidation state, molecular formula, and CAS number (1308-38-9 for Cr₂O₃) is the standard supporting document. Customs brokers may also request X-ray diffraction or wet chemistry test results for high-value or ambiguous shipments, particularly when the product originates from a supplier that also produces chromium trioxide.
