U.S. imports of vanadium oxides and hydroxides (HS 282530) totaled $5.8M in May 2026, traded with 6 countries.
Importers of Vanadium Oxides and Hydroxides paid $334K in duties in May 2026 — an effective duty rate of 16% on $2.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Vanadium Oxides and Hydroxides imports of $5.8M in May 2026 ran 44% above the year-to-date monthly average of $4.0M.
Last updated: May 2026 dataVanadium pentoxide (2825300010) is the dominant commercial form under this heading, serving as the primary feedstock for ferrovanadium production and as a catalyst in sulfuric acid manufacturing. South Africa and Brazil lead US import supply, consistent with their roles as major vanadium ore and slag processors. A second line (2825300050) captures other vanadium oxides not elsewhere specified, including lower-valence forms used in specialty chemical and battery applications such as vanadium redox flow systems. Importers should note that China is also among the top suppliers, and Section 301 tariff exposure should be evaluated for shipments of Chinese origin.

Tariff line 2825300010 is reserved specifically for vanadium pentoxide (V₂O₅), the most commercially prevalent form. All other vanadium oxides — including vanadium trioxide (V₂O₃) and vanadium dioxide (VO₂) — are classified under 2825300050 as 'other vanadium oxides, NESOI.' The chemical formula and oxidation state of the product should be confirmed in the supplier's certificate of analysis before filing entry.
Steel alloying via ferrovanadium is the largest end use, where vanadium pentoxide is the key precursor. Growing demand from vanadium redox flow battery manufacturers for grid-scale energy storage is an emerging driver. Catalyst applications in sulfuric acid production also represent a steady industrial demand segment.
