U.S. imports of oxides, hydroxides, and peroxides of strontium or barium (HS 281640) totaled $448K in April 2026, traded with 6 countries.
Importers of Oxides, Hydroxides, and Peroxides of Strontium or Barium paid $9K in duties in April 2026 — an effective duty rate of 2.0% on $442K in dutiable value, based on actual customs collections rather than the published tariff schedule. Oxides, Hydroxides, and Peroxides of Strontium or Barium imports of $448K in April 2026 ran 61% above the year-to-date monthly average of $278K.
Last updated: April 2026 dataBarium and strontium compounds in this heading — including barium oxide, barium hydroxide, strontium oxide, and their peroxides — serve niche but technically demanding roles in specialty glass manufacturing, ceramic capacitors, pyrotechnics, and as analytical reagents. The US schedule separates strontium compounds (2816401000) from barium compounds (2816402000), reflecting distinct end-use markets and supply chains. China dominates global supply of both strontium and barium minerals and their derivatives, making it the leading import source under this heading.

The US tariff schedule splits the heading by metal: 2816401000 covers all oxides, hydroxides, and peroxides of strontium, while 2816402000 covers the corresponding barium compounds. Importers must identify the specific alkaline earth metal in the shipment — not just the compound type — to select the correct 10-digit line.
Barium hydroxide monohydrate is a primary input for producing barium-containing specialty chemicals, including barium sulfate for high-purity coatings and barium titanate for electronic capacitors. It is also used in sugar refining as a clarifying agent and in lubricant additive synthesis. The electronics and specialty coatings sectors drive the bulk of commercial demand.
