Compliance notes
CAS and identity check required: Sodium Hydroxide, CAS 1310-73-2
DG/export awareness: sodium hydroxide solid is commonly shipped as dangerous goods; supplier page references UN 1823
Confirm UN number, proper shipping name, hazard class, packing group, marine pollutant status if applicable, and destination-country import requirements with freight forwarder
Request current SDS/MSDS in buyer-required language and format before shipment
Request COA for each batch showing assay and impurity limits
Supplier states COA, MSDS/SDS, TDS, Certificate of Origin, and SGS reports can be provided; verify document dates and issuing parties
Do not rely on listing claims for regulatory approval; buyer should confirm local import, storage, labeling, and end-use compliance
Food-grade use requires separate grade confirmation, specification, and compliant documentation; do not treat industrial grade as food grade
