HS 29.20.21

Esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, dimethyl phosphite

ℹ Many substances in this chapter (organic chemicals) may be classified as dangerous goods under ADR. Common hazard classes include Class 3 (flammable liquid), Class 6.1 (toxic), and Class 8 (corrosive). Always check individual substance classification before transport. Check ADR classification →
Classification is the shipper’s legal responsibility. This reference is based on common HS-ADR correlations from public regulatory data. Always verify against the current ADR, IMDG Code, or IATA DGR and consult a qualified DGSA where required.
