Caustic Soda Pearls / Sodium Hydroxide Industrial Grade, CAS 1310-73-2
Buyer-facing sourcing candidate for sodium hydroxide solid form marketed as caustic soda pearls, with CAS 1310-73-2, formula NaOH, EINECS 215-185-5, and industrial grade positioning. The source page lists industrial-grade caustic soda under a pearls title but also references flakes, so buyers should confirm the supplied physical form, assay, impurity limits, COA format, packing, and dangerous goods export documentation before RFQ confirmation.

Packing notes
Source page lists transport package as bag and specification as 25 kg.
MOQ listed as 1 x 20GP container.
Confirm whether packing is 25 kg PP/PE bags, kraft bags, jumbo bags, palletized bags, or container-loaded loose bags.
Confirm moisture-barrier packaging, bag lining, net weight tolerance, pallet dimensions, container loading quantity, and whether export marks can be customized.
Request photos of current production packing and recent container loading records if shipment integrity is critical.
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 pH adjustment and neutralization applications where permitted and properly controlled
Water treatment chemical programs requiring industrial alkali sourcing
Pulp, paper, textile, and dyeing processes requiring caustic alkali feedstock
Petroleum, refinery, and general chemical manufacturing procurement where industrial-grade caustic soda is specified
How we compare
Sourcing options
25 kg bagged industrial-grade caustic soda pearls, subject to form confirmation
25 kg bagged caustic soda flakes if pearls are not the actual supplied form
Full-container 20GP order based on listed MOQ
Repeat monthly container supply subject to capacity and compliance checks
Third-party inspected shipment with COA, SDS, packing list, commercial invoice, and DG transport documents
Human review
Compliance notes
Request current COA showing NaOH assay and impurity profile before purchase confirmation.
Request SDS in buyer-required language and format, plus transport dangerous goods documentation suitable for the shipping mode.
Sodium hydroxide is a corrosive dangerous good; confirm DG classification, packing group, marine pollutant status if applicable, and carrier acceptance for the actual product form.
The source page lists UN No. 1824, which is commonly associated with sodium hydroxide solution; buyers should verify whether solid caustic soda should be shipped under the applicable solid-form UN entry and ensure documents match the material supplied.
Industrial grade does not automatically indicate food, pharmaceutical, or reagent suitability; confirm intended-use grade and local import requirements.
ISO 9001 is referenced in the title, but certificate scope, validity, issuing body, and manufacturer name should be checked.
No regulatory clearance, import approval, or end-use authorization should be assumed from the listing.
Confirm export control, customs classification, labeling, and destination-country restrictions with qualified logistics and compliance parties.
