An authoritative analysis of chemistry specifications, logistics regulations, and global industrial procurement dynamics.
Sodium sulfide (chemical formula: Na₂S) is an inorganic chemical compound that is widely deployed in crucial industrial processes. In its commercial state, it typically exists as hydrated yellow or red flakes, with a target concentration of 60% active Na₂S. This 60% concentration represents the stable crystalline form, primarily equivalent to the trihydrate variant (Na₂S·3H₂O).
The product is divided into two primary commercial variants based on iron (Fe) impurity concentrations:
Professional Insight: When procuring Sodium Sulfide 60% from any plant, the primary quality control metrics are the percentage of active Na₂S, the iron (Fe) content, the sodium carbonate (Na₂CO₃) density, and water-insoluble residue. High-quality plants maintain rigorous analytical labs using Inductively Coupled Plasma (ICP) spectroscopy and conventional titration methods to ensure batch-to-batch consistency.
Under international transport regulations, Sodium Sulfide 60% Flakes is categorized as a Class 8 Hazardous Substance (UN 1849) due to its corrosive and toxic nature. It poses significant handling challenges due to its hygroscopic characteristics and potential to release toxic hydrogen sulfide (H₂S) gas when exposed to acids or moisture.
Procurement teams must ensure that suppliers are fully compliant with International Maritime Dangerous Goods (IMDG) packing requirements. Packaging formats include 25kg PP/PE woven bags with double-layered inner liners, or 1000kg to 1200kg UN-certified jumbo bags with integrated moisture barriers. Protection from ambient humidity and direct sunlight is mandatory to prevent product liquefaction and gas buildup during maritime transit.
Crucial in copper-molybdenum ore separation. Used as a sulfidizing agent for oxide ores, enabling optimal xanthate collector attachment during froth flotation.
Breaks down the keratin cross-links in raw hides in beamhouse processing. Lower iron grades prevent iron-tannin staining on premium leather products.
Precipitates dissolved heavy metals (copper, nickel, cadmium, lead) from industrial wastewater. It is highly effective at low concentration thresholds.

The main difference is the iron impurity level. Yellow flakes are low-iron (typically under 10 ppm to 30 ppm), used in bleaching and dyeing applications to prevent color deviations. Red flakes have higher iron levels (up to 150 ppm) and are suitable for mining flotation processes.
Store in a cool, dry, well-ventilated warehouse. Keep away from heat, sparks, open flames, and acidic chemicals. Sodium sulfide must be handled with appropriate PPE, including chemical safety goggles, gloves, and respiratory protection.
