Compliance notes
Sodium hydroxide is a hazardous corrosive chemical; DG classification, UN number, packing group, and transport labels must be confirmed from current SDS and booking documents
Request current COA, SDS, TDS/spec sheet, ISO 9001 certificate copy if applicable, commercial invoice, packing list, certificate of origin, and bill of lading draft for review
For India-bound shipments, buyer should confirm import license/registration needs, customs HS code, port acceptance, and local hazardous chemical requirements with licensed customs and compliance advisors
Supplier page claims hazardous status; RFQ should ask for DG cargo booking experience and whether documents match IMDG/IATA/road/rail requirements as applicable
No regulatory guarantee should be assumed from marketplace listing data; rely on current batch documents and destination-country review
Confirm that product is not being marketed for food, pharma, medical, or consumer use unless supported by appropriate grade documentation and approvals

Please confirm whether the quoted product is 98% min or 99% min NaOH, since both values appear in the source information.
Which physical form is available for export now: flakes, pearls, or both?
What is the current MOQ, FOB/CFR/CIF price indication, and validity for shipment to India?
Which Chinese port is used for export, and do you have recent DG booking records for sodium hydroxide shipments?
Please confirm UN number, hazard class, packing group, and whether the shipment can be booked as dangerous goods with complete SDS and labels.
What packing options are available: 25 kg bags only, palletized bags, jumbo bags, or customized export marks?
Can you provide current SDS, TDS, COA, ISO certificate, certificate of origin, packing photos, and draft shipping documents before payment balance?
