Packing notes
Transport package listed: 25 kg/bag
Specification listed: 25 kg/bag
MOQ from FAQ listed as 1 MT; confirm current MOQ and palletization
Request photos of bag markings, batch number, net weight, production date, and hazard labels before shipment
Confirm container loading quantity, pallet or non-pallet packing, moisture-protection measures, and export carton/bag strength
Ask whether packing is suitable for destination-port DG acceptance and buyer warehouse requirements
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Industrial alkali raw material procurement
pH adjustment and neutralization applications subject to buyer process validation
Detergent and cleaning formulation manufacturing subject to grade qualification
Textile, pulp, paper, and general chemical processing where industrial sodium hydroxide is specified
Distribution stock for industrial customers requiring CAS 1310-73-2 and HS 28151100 documentation
How we compare
Sourcing options
98.5% caustic soda flakes in 25 kg bags
99% caustic soda pearls in 25 kg bags
Solid sodium hydroxide export order by MT or container load
FOB China port quotation with buyer-nominated forwarder
CFR/CIF quotation subject to DG carrier acceptance and destination port rules
Batch-specific COA and English SDS package for RFQ review
Human review
Compliance notes
Sodium hydroxide is a corrosive chemical and should be sourced with DG/export documentation reviewed before booking shipment
Request current SDS, COA, commercial invoice, packing list, certificate of origin if needed, and DG transport documents where applicable
Confirm UN number, hazard class, packing group, marine pollutant status if applicable, and destination-country import requirements with the freight forwarder
Do not rely on marketplace page claims as regulatory clearance; buyer/importer should verify local chemical registration, customs coding, and end-use restrictions
Check whether the supplier can provide batch-specific COA matching NaOH assay and impurity limits before payment or release
Confirm whether the product is industrial grade only and whether it is unsuitable for regulated food, pharmaceutical, cosmetic, or other controlled uses unless independently qualified
