HSN Code Details
Hydrogen cyanide, sold as hydrocyanic acid, is a colorless liquid with a sharp, bitter almond scent; unlike HSN 28111100, which covers sodium cyanide, this code covers the acid form used in chemical synthesis.
When shipping this corrosive liquid, it must be contained in ISO‑class 2 secondary containers, sealed with double‑layered polyethylene, and accompanied by a Hazardous Materials Declaration to ensure safe handling across borders.
