U.S. imports of Manganese Oxides (SITC 52253) totaled $2.3M in August 2026, imported from 18 countries.
Importers of Manganese Oxides paid $77K in duties in August 2026, an average duty rate of 3.33% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataManganese oxides — including manganese dioxide (MiO₂), manganese(II) oxide, and higher oxides — are essential inputs for dry-cell battery production, ferrite manufacturing, and water treatment chemicals. Battery-grade manganese dioxide commands a significant price premium over technical-grade material, and the grade distinction is commercially critical for both classification and procurement. Supply-chain considerations include the concentration of manganese ore processing in a limited number of countries, which can create availability risk for battery manufacturers scaling production.

At the SITC level, manganese oxides are grouped together regardless of grade, but at the HTS 10-digit level, distinctions may exist based on specific compound type. More practically, battery-grade versus technical-grade manganese dioxide will differ in purity specifications that buyers and customs brokers should document to support correct classification and avoid disputes.
Battery manufacturing — particularly for alkaline and lithium-ion cells — is the leading demand driver, with manganese dioxide serving as a cathode material. Water treatment and specialty chemical applications provide secondary demand, but the battery sector's growth has made supply security a growing concern for importers.
