Human review

Compliance notes

  • Verify CAS 1310-73-2 and product identity against COA, SDS, label, and commercial invoice before shipment.
  • Caustic soda is a corrosive strong alkali; confirm applicable dangerous goods classification, UN number, packing group, transport labels, and carrier acceptance for the destination route.
  • Request current SDS in English and, where needed, destination-language SDS or GHS label format from the supplier.
  • Request COA for each batch and confirm test methods for NaOH assay, sodium carbonate, sodium chloride, iron, water-insoluble matter, and moisture where applicable.
  • Do not rely on marketplace description for regulatory status; importer should verify local import controls, DG transport rules, customs codes, and end-use restrictions with qualified local advisors.
  • Confirm export documentation readiness: commercial invoice, packing list, COA, SDS, certificate of origin if required, bill of lading details, and any destination-specific pre-shipment documents.
  • Confirm whether the supplier is trading company or manufacturer, and whether factory audit, batch traceability, and third-party inspection can be arranged.
  • Payment terms require confirmation; source page states O/A, D/P, and cash on delivery are not supported.
