U.S. imports of sodium sulfide (SITC 52341) totaled $335K in April 2026, traded with 9 countries.
Importers of Sodium Sulfide paid $47K in duties in April 2026 — an effective duty rate of 14% on $335K in dutiable value, based on actual customs collections rather than the published tariff schedule. Sodium Sulfide imports of $335K in April 2026 ran 11% below the year-to-date monthly average of $378K.
Last updated: April 2026 dataSodium sulfide is a key reducing agent in the kraft pulping process, where it reacts with wood chips to dissolve lignin, and also serves as a raw material in the production of sulfur dyes, rubber chemicals, and leather depilatory agents. Its high alkalinity and release of hydrogen sulfide gas under acidic conditions classify it as a hazardous material, requiring DOT-compliant packaging and emergency-response documentation at the port of entry. Trade in sodium sulfide is sensitive to pulp-mill capacity utilization cycles, and importers should monitor whether shipments are subject to antidumping measures, which have historically been applied to certain inorganic chemicals from specific origins.

Sodium sulfide must be accompanied by a Safety Data Sheet (SDS) and shipped in DOT-compliant packaging for corrosive and toxic materials. Carriers and freight forwarders must be notified of its hazardous classification, and ports may require specific handling procedures due to the risk of hydrogen sulfide gas generation if the product contacts moisture or acids.
The largest end-use is kraft pulp and paper manufacturing, where sodium sulfide is a core component of the cooking liquor. Secondary markets include sulfur dye production for textile dyeing, leather processing (as a depilatory in hide preparation), and the synthesis of various organosulfur compounds used in rubber and specialty chemicals.
