Industrial Grade Sodium Hydroxide Flakes / Caustic Soda Flakes CAS 1310-73-2
Buyer-facing sourcing candidate for industrial grade caustic soda flakes / sodium hydroxide. The listing claims CAS 1310-73-2, NaOH, white flakes or pearls, 99% purity, 20 ton MOQ, and 25 kg bag packing options. Buyers should verify CAS, HS code, COA values, grade, concentration, sodium carbonate content, chloride/iron limits, DG classification, export documents, and whether the offered material is sodium hydroxide rather than sodium carbonate due to inconsistencies in the source text.

Package and route
Packing notes
Source page states 25 kg/bag or customized packing per customer requirement
Source page also references standard carton + pallet; confirm actual export packing for caustic soda flakes
Request bag material, liner type, moisture barrier, palletization, net/gross weight, and container loading plan
Confirm whether packing is suitable for ocean export of corrosive alkali solids
Request product label draft showing product name, CAS, batch number, net weight, hazard pictograms, manufacturer/exporter details, and country of origin
Confirm container quantity for FCL shipment and whether mixed loading is permitted under carrier rules
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 sourcing where buyer has qualified internal handling and use controls
pH adjustment or neutralization applications subject to buyer's site procedures and local regulations
Chemical manufacturing feedstock where impurity limits such as carbonate, chloride, and iron are important
Detergent, textile, paper, dye, petroleum, and general industrial sectors requiring bulk caustic soda flakes
Distributor stock replenishment for properly classified corrosive alkali products
How we compare
Sourcing options
Request a firm quotation for 20 MT FCL industrial grade 99% sodium hydroxide flakes in 25 kg bags
Request separate quotes for flakes versus pearls if both forms are available
Request FOB China port and CIF destination port pricing with DG freight included or separately itemized
Request pre-shipment inspection and third-party testing for CAS, assay, and impurity confirmation
Request document review before payment, including SDS, COA, label, HS code, and DG declaration
Request palletized export packing if warehouse handling and unloading conditions require it
Human review
Compliance notes
Sodium hydroxide is a corrosive alkali and should be treated as dangerous goods for transport classification checks
Verify UN number, proper shipping name, hazard class, packing group, marine pollutant status if applicable, and emergency contact information on SDS and shipping documents
Request English SDS compliant with destination market expectations before order confirmation
Do not rely on marketplace claims alone; match CAS 1310-73-2, NaOH assay, and DG classification across COA, SDS, invoice, packing list, label, and B/L
Source text contains a material inconsistency: product title says sodium hydroxide CAS 1310-73-2, while product table includes CAS 497-19-8 and HS code 28362000, commonly associated with sodium carbonate. This must be resolved before RFQ acceptance
Request supplier business license, export qualification, recent COA, SDS, certificate of origin, packing list, commercial invoice template, and DG transport documents where applicable
Confirm destination-country import requirements with buyer's customs broker; no regulatory approval or clearance outcome should be assumed
Confirm whether any end-use, customer, destination, or sanctions screening is required before shipment

Questions to confirm
Can you confirm the offered product is sodium hydroxide CAS 1310-73-2, not sodium carbonate CAS 497-19-8?
Please provide the latest COA showing NaOH assay, sodium carbonate, sodium chloride, iron, moisture, insoluble matter, and batch number.
What is the exact grade available: industrial grade only, or also reagent/electronic/other grades?
Is the physical form flakes, pearls, or both? Please quote separately if both are available.
What is the standard export packing: 25 kg bags, lined bags, jumbo bags, pallets, or customized packing?
Can you provide English SDS, DG declaration, COA, commercial invoice, packing list, certificate of origin, and B/L draft?
What UN number, hazard class, packing group, and proper shipping name will be used for ocean freight?
What HS code will you declare for sodium hydroxide flakes, and can you confirm it with supporting documentation?
