Standard International Trade Classification
U.S. imports of Magnesium Hydroxide and Peroxide; Strontium and Barium Oxides, Hydroxides, and Peroxides (SITC 52265) totaled $3.1M in August 2026, imported from 17 countries.
Importers of Magnesium Hydroxide and Peroxide; Strontium and Barium Oxides, Hydroxides, and Peroxides paid $134K in duties in August 2026, an average duty rate of 4.35% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataMagnesium hydroxide — sold commercially as milk of magnesia in pharmaceutical grades and as a flame retardant in industrial grades — shares this heading with the less common strontium and barium compounds used in specialty ceramics, pyrotechnics, and electronic materials. The breadth of the heading means that grade and end-use documentation are critical: pharmaceutical-grade magnesium hydroxide faces different admissibility scrutiny than the industrial flame-retardant form. Barium compounds in particular may require additional safety data sheet disclosures given their toxicological profile, and importers should confirm TSCA inventory status for any barium or strontium derivative not previously imported.

Yes. Magnesium hydroxide intended for drug or antacid use is regulated by FDA as an active pharmaceutical ingredient or OTC drug component, and shipments may be subject to FDA examination at the port of entry. Importers should ensure the foreign manufacturer is registered with FDA and that the product meets USP purity specifications.
Both grades classify under the same SITC heading, but the commercial distinction lies in purity, particle size, and intended use. Industrial grades used as flame retardants or wastewater neutralizers typically carry lower purity specifications, while pharmaceutical grades must meet USP or equivalent pharmacopeial standards. Declaring the correct end-use on entry documents helps avoid reclassification or admissibility holds.
