A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Sodium cyanide (CAS 143-33-9, NaCN), a highly reactive inorganic salt. Used to extract gold and silver from ores, in electroplating and metal heat-treating, and as a chemical intermediate for dyes, chelating agents, and nylon precursors.
Frequently Asked Questions
What is sodium cyanide used for?
Sodium cyanide (CAS 143-33-9, NaCN) is a highly reactive inorganic salt used as a lixiviant to extract gold and silver from ores, in electroplating and metal heat-treating (case-hardening of steel), and as a chemical intermediate for dyes, chelating agents, and nylon precursors.
What is the chemical formula of sodium cyanide?
Sodium cyanide has the formula NaCN (CAS 143-33-9). It is the sodium salt of hydrocyanic acid.
What HS code is sodium cyanide?
Sodium cyanide is classified under HS 2837.11 (cyanides and cyanide oxides of sodium). Confirm the destination-country tariff line and applicable import controls with your order.
How is sodium cyanide classified for shipping?
Sodium cyanide ships as UN 1689 (SODIUM CYANIDE). DOT/IMDG documentation, proper packaging, and the SDS must accompany every shipment; review the SDS for full handling and transport requirements before ordering.
How is bulk sodium cyanide supplied and quoted?
It is supplied to mining, plating, and chemical-manufacturing operations in controlled industrial packaging. Pricing depends on grade, packaging, and volume — request a bulk quote and the SDS; identity and purity are documented on the CoA.
