U.S. exports of manganese oxides (except manganese dioxide) (HS 282090) totaled $1.2M in July 2026.
Importers of Manganese Oxides (Except Manganese Dioxide) paid $39K in duties in July 2026 — an effective duty rate of 13% on $298K in dutiable value, based on actual customs collections rather than the published tariff schedule. Manganese Oxides (Except Manganese Dioxide) imports of $314K in July 2026 ran 54% below the year-to-date monthly average of $684K.
Last updated: July 2026 dataManganese oxides other than MnO₂ — including manganous oxide (MnO), manganese sesquioxide (Mn₂O₃), and trimanganese tetroxide (Mn₃O₄) — serve as colorants in ceramics and glass, micronutrient sources in animal feed, and precursors in specialty chemical synthesis. India leads US imports under tariff line 2820900000, with Gabon and Mexico also significant sources. Gabon's prominence reflects its position as one of the world's largest manganese ore producers, giving it a natural cost advantage in downstream oxide processing. Importers should confirm the specific oxide stoichiometry in supplier documentation, as different manganese oxide phases carry distinct technical and regulatory profiles.

Customs entries for manganese oxides other than MnO₂ should be supported by a certificate of analysis specifying the chemical formula or phase (e.g., MnO, Mn₂O₃, Mn₃O₄) and purity percentage. This documentation helps distinguish the product from manganese dioxide (2820.10) and from manganese metal or alloys classified elsewhere, reducing the risk of a CF-28 request for additional information at entry.
Trimanganese tetroxide (Mn₃O₄) is widely used as a precursor for lithium manganese oxide (LMO) battery cathode materials. Manganous oxide (MnO) is a primary micronutrient additive in fertilizers and animal feeds. Manganese sesquioxide finds use in specialty pigments and catalysts. Each grade commands a different price point and is sourced from different supplier types, so specifying the correct phase in purchase orders is commercially as well as legally important.
