U.S. exports of peroxides of sodium or potassium (HS 281530) totaled $327K in July 2026.
Importers of Peroxides of Sodium or Potassium paid $8K in duties in July 2026 — an effective duty rate of 4.8% on $162K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataSodium peroxide and potassium peroxide are strong oxidizing agents used in oxygen-generating systems, bleaching applications, and as laboratory reagents; their high reactivity with moisture demands specialized packaging and hazmat handling throughout the supply chain. Both compounds are captured under a single tariff line (2815300000), and France is the leading US import source — reflecting the dominant global production position of Solvay and related European chemical manufacturers. China is also a notable supplier, and given the reactive nature of these compounds, importers should ensure compliance with DOT hazardous materials regulations governing oxidizer classification.

Sodium peroxide is classified as a Division 5.1 oxidizer (and may carry a subsidiary corrosive hazard) under DOT 49 CFR. Shipments require proper UN-numbered packaging, hazardous materials shipping papers, and placarding. Importers should verify current DOT and IMDG requirements with their freight forwarder before arranging ocean or overland transport.
No. Sodium peroxide (Na₂O₂) falls under 2815300000 as an alkali metal peroxide. Sodium percarbonate — a different compound used as a laundry bleach — is classified elsewhere in Chapter 28 as a carbonate derivative. The chemical formula and compound identity, not just the word 'peroxide,' determine correct classification.
