Last updated: August 2026 dataSodium sulfide — a key reducing agent and pulping chemical used in kraft paper production, leather tanning (depilation), and dye synthesis — is classified under a single 10-digit line (2830100000). China is the dominant US import source by a wide margin, reflecting its large-scale inorganic chemical manufacturing capacity, with Germany and Singapore also supplying the market. Importers sourcing from China should assess Section 301 tariff exposure, and all shipments require careful hazardous materials handling given sodium sulfide's classification as a flammable solid and its generation of toxic hydrogen sulfide gas upon contact with acids.

Sodium sulfide is classified as a Class 4.2 flammable solid (spontaneously combustible) under DOT and IMDG regulations when shipped in anhydrous or low-hydration form, and as a Class 8 corrosive in some hydrated forms. All shipments require UN-approved packaging, appropriate hazard labels, and an emergency response information document. Importers should also ensure TSCA compliance and review SDS requirements for the specific hydration grade being imported.
Sodium sulfide is commercially available in anhydrous form and as hydrated flakes or crystals (commonly 60% or 30% Na₂S content). The hydration level affects reactivity, handling safety, and end-use suitability — for example, kraft pulp mills typically specify a particular sulfidity grade. While all grades fall under the same 10-digit HTS line (2830100000), the product specification must be clearly documented on the commercial invoice to support accurate valuation and any applicable quality certifications.
