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.
What is the REACH and TSCA regulatory status of Sodium Cyanide (NaCN)?
Sodium Cyanide (NaCN) (CAS 143-33-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 205-599-4).
