Sodium cyanide is a highly toxic white crystalline powder with a faint bitter almond odor. It exhibits strong alkalinity in water and is primarily used in gold and silver extraction, electroplating, pesticide production, and pharmaceutical synthesis. However, due to its extreme toxicity and severe environmental hazards, its production, transportation, storage, and use are strictly regulated. All operations must be conducted in sealed facilities under constant supervision and with emergency response measures in place.

Sodium cyanide is a vital basic chemical raw material used in fundamental chemical synthesis, electroplating, metallurgy, and organic synthesis for pharmaceuticals, pesticides, and metal treatment. It serves as a chelating agent and masking agent in the refining and electroplating of precious metals such as gold and silver.
Packaging Method: Place in plastic bags with sealed openings, then pack into sturdy steel drums with a wall thickness of no less than 0.75 mm. Securely fasten the drum lids. Net weight per drum: 50 kg. For threaded-mouth glass bottles, screw-cap glass bottles, plastic bottles, or metal drums (cans), pack in ordinary wooden crates; however, glass bottles must be additionally wrapped in plastic bags.
Transportation Precautions: For rail transport, strictly adhere to the dangerous goods loading table in the Ministry of Railways' “Rules for Transporting Dangerous Goods.” Prior to shipment, inspect packaging containers for integrity and seal integrity. During transport, ensure containers remain leak-free, upright, secure, and undamaged. Strictly prohibited from being transported with acids, oxidizing agents, foodstuffs, or food additives. Transportation vehicles must be equipped with emergency leak response equipment. During transit, protect from direct sunlight, rain, and high temperatures. For road transport, follow designated routes; stopping in residential areas or densely populated zones is prohibited.
