HSN Code Details
Arsenic trioxide is a white, crystalline powder that dissolves readily in water, giving it a slightly bitter taste; unlike arsenic pentoxide (HSN 28112930), it lacks the additional oxygen atoms that give the latter a higher molecular weight.
When shipping arsenic trioxide, containers must be sealed with tamper‑evident seals and labeled with proper hazard symbols, and the shipment must include a Certificate of Analysis detailing purity levels.
