Sodium Hydrosulfide
Other names: Sodium sulfhydrate / Sodium hydrogen sulfide / Sodium bisulfide / NaHS flakes
CAS No: 16721-80-5
H.S CODE: 2830.10.90
Molecular Formula: NaHS
Molecular Weight: 56.06
Known as sodium sulfhydrate, sodium hydrosulfide (NaHS) is supplied as yellow flakes with a characteristic hydrogen sulfide odor. It is highly soluble in water, forming a strongly alkaline solution. When it contacts with acids, it decomposes and releases toxic hydrogen sulfide (H2S) gas. It is hygroscopic and must be kept sealed, away from moisture and air.

Sodium Hydrosulfide Applications
Sodium hydrosulfide is used across mineral processing, leather production, pulp and paper, and chemical manufacturing.
Mining and Mineral Processing
NaHS is used as a flotation reagent in mineral processing, including certain copper and molybdenum separation processes. Product selection depends on the ore and flotation conditions.
Leather Processing
Sodium hydrosulfide is used in hide and skin processing, including dehairing operations. Buyers should review NaHS content and impurity limits against their process requirements.
Pulp and Paper
NaHS provides a source of sulfur for relevant pulp processing and chemical management applications.
Chemical and Dye Manufacturing
Sodium hydrosulfide is used as a reagent in selected chemical and dye manufacturing processes.
Share your intended application and required impurity limits so we can discuss the appropriate product specification.
Packaging and Shipping
Our sodium hydrosulfide flakes are packed in PP woven bags with PE inner liners.
| Packaging Option | Net Weight per Bag | Equivalent to 1 MT |
|---|---|---|
| Small Bags | 25 kg | 40 bags |
| Jumbo Bags | 1,000 kg | 1 bag |
Pallet arrangements, container loading quantities, shipping schedules, and destination requirements should be confirmed during quotation.
FOB quotations: Please specify your preferred loading port, if applicable.
CIF quotations: Please provide the destination port and country so freight and insurance can be included in the offer.
Product Properties and Storage
Sodium hydrosulfide is highly soluble in water and forms a strongly alkaline solution. It is hygroscopic and should be kept in sealed packaging, protected from moisture and unnecessary exposure to air.
Contact with acids can release toxic hydrogen sulfide gas. Follow the product Safety Data Sheet for handling, storage, protective equipment, and transport requirements.
Quality Specifications and Purchasing Support
Our listed specification covers NaHS content, sodium carbonate, sodium sulfide, and iron. These parameters help buyers assess product suitability beyond the nominal 70% concentration.
When requesting a quotation, please include:
Required NaHS content and impurity limits.
Intended industrial application.
Order quantity and packaging preference.
Destination country and port.
Required inspection and shipping documents.
Please request the relevant COA and SDS for review before confirming your order. Any additional testing or documentation requirements should be agreed in advance.
Sodium Hydrosulfide Price and Purchase FAQ
What is the sodium hydrosulfide price?
The indicative price is USD 540–620 per metric ton. Final pricing depends on order quantity, packaging, specifications, shipping conditions, and the agreed trade term. Request a current quotation for your order.
What is the minimum order quantity?
The MOQ is 1 metric ton, equivalent to 40 bags of 25 kg or one 1,000 kg jumbo bag.
Do you offer FOB and CIF quotations?
Yes. We offer FOB and CIF quotations. Provide your order quantity, packaging preference, and destination port so we can prepare the appropriate offer.
Is the NaHS content 70% or 71.30%?
The product specification is 70.0% minimum NaHS. The 71.30% figure is the result shown in the supplied inspection report, rather than the guaranteed content of every shipment.
What should buyers compare when evaluating sodium hydrosulfide manufacturers and suppliers?
Compare NaHS concentration, impurity limits, inspection records, packaging, delivery conditions, and quotation scope. Use the same specifications and trade terms when comparing prices.
How can I buy sodium hydrosulfide from NBWCHEM?
Send us your required quantity, application, packaging preference, destination port, and any special specifications. We will discuss product requirements and prepare a quotation.
What are the lead time and payment terms?
Please confirm lead time and payment terms when requesting your quotation. These will be agreed for the specific order.
