SITCSection 5
U.S. imports of hydrogen peroxide, solidified or not with urea (SITC 52491) totaled $3.7M in April 2026, traded with 18 countries.
Importers of Hydrogen Peroxide, Solidified or Not with Urea paid $116K in duties in April 2026 — an effective duty rate of 14% on $806K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataHydrogen peroxide is a versatile oxidizing agent traded in aqueous concentrations ranging from dilute consumer grades to high-strength industrial solutions used in pulp and paper bleaching, textile processing, semiconductor wafer cleaning, and propellant applications. The urea-hydrogen peroxide adduct (carbamide peroxide) is a solid, stabilized form used in tooth-whitening formulations and pharmaceutical applications, and its inclusion in this heading reflects its chemical equivalence to liquid H₂O₂ for classification purposes. High-concentration hydrogen peroxide is subject to DHS Chemical Facility Anti-Terrorism Standards (CFATS) reporting thresholds, adding a security-compliance dimension beyond standard hazmat requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
DHS CFATS regulations establish specific threshold quantities for hydrogen peroxide at concentrations of 35% or greater. Facilities that receive or store quantities at or above the applicable screening threshold quantity must report to DHS and may be subject to site security plan requirements. Importers and their consignees should confirm current thresholds with a compliance specialist, as regulatory details can change.
No — both liquid hydrogen peroxide and its solid urea adduct (carbamide peroxide) fall within the same SITC heading. However, at the HTS level, the physical form and concentration can affect the specific tariff subheading, so importers should verify the correct 10-digit HTS code against the product's specification sheet and declared concentration.
