SITCSection 5
U.S. imports of potassium hydroxide (caustic potash) and sodium or potassium peroxides (SITC 52264) totaled $6.3M in April 2026, traded with 22 countries.
Importers of Potassium Hydroxide (Caustic Potash) and Sodium or Potassium Peroxides paid $216K in duties in April 2026 — an effective duty rate of 26% on $824K in dutiable value, based on actual customs collections rather than the published tariff schedule. Potassium Hydroxide (Caustic Potash) and Sodium or Potassium Peroxides imports of $6.3M in April 2026 ran 41% above the year-to-date monthly average of $4.5M.
Last updated: April 2026 dataCaustic potash (potassium hydroxide) is a strong alkali widely used in fertilizer production, soap manufacturing, and battery electrolytes, while sodium and potassium peroxides serve as oxidizing agents in specialty chemical and bleaching applications. Classification under this heading turns on the specific compound: anhydrous versus solution forms of potassium hydroxide carry different commercial grades and packaging requirements that affect duty treatment. Importers should verify whether the peroxide fraction meets purity thresholds that distinguish industrial-grade from reagent-grade material, as misclassification between these compounds is a common customs audit trigger.

The two alkalis fall under separate SITC headings based on the cation: potassium-based compounds classify here (52264), while sodium hydroxide has its own heading. The distinction matters because duty rates, antidumping exposure, and supplier sourcing patterns differ between the two commodities.
Potassium and sodium peroxides are classified as oxidizing hazardous materials under DOT regulations, so shipments require proper dangerous-goods declarations, UN-number labeling, and compatible packaging certifications. Importers should also confirm EPA TSCA compliance for any new chemical substance not already on the TSCA inventory.
