Ferric chloride
三氯化铁
From the buying desk
Anhydrous ferric chloride ships as UN1773; the liquid solution ships as UN2582, so the booking must match the form. It is very hygroscopic and corrosive to steel, so packaging integrity matters. Water treatment buyers usually buy the solution closer to home and import the anhydrous or hexahydrate solid.
