U.S. imports of Salts of Oxometallic or Peroxometallic Acids (SITC 52431) totaled $89.3M in August 2026, imported from 27 countries.
Importers of Salts of Oxometallic or Peroxometallic Acids paid $8.7M in duties in August 2026, an average duty rate of 8.99% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Salts of Oxometallic or Peroxometallic Acids imports of $89.3M in August 2026 ran 86% above the year-to-date monthly average of $47.9M.
Last updated: August 2026 dataPermanganates, chromates, dichromates, manganates, molybdates, tungstates, and vanadates are the commercially prominent members of this heading, each serving distinct industrial roles: potassium permanganate in water treatment and chemical synthesis, chromates and dichromates in metal finishing and pigments, and molybdates as corrosion inhibitors and catalyst precursors. Several chromate compounds face significant regulatory scrutiny under EPA and REACH-equivalent frameworks due to hexavalent chromium toxicity, which affects both import admissibility documentation and downstream handling requirements. Molybdate and tungstate salts are also strategically significant as downstream derivatives of critical minerals.

Hexavalent chromium compounds, including sodium and potassium chromate and dichromate, are regulated as hazardous substances under EPA rules and require proper TSCA compliance and hazmat shipping documentation. Downstream users in metal finishing must also comply with OSHA permissible exposure limits and, for export-oriented products, may face restrictions under international frameworks targeting hexavalent chromium.
Molybdates are downstream derivatives of molybdenum, a critical mineral used in high-strength steel alloys, catalysts, and electronics. Supply concentration in a small number of producing countries means that import disruptions can ripple into steel, petroleum refining, and specialty chemical supply chains, making origin diversification and inventory management important considerations for industrial buyers.
