Logistics & Documentation
Plastic-Pallet Option · Import Documentation Support
- Lead Time: Depends on supplier availability, production schedule, shipping route and destination. Lead time and dispatch are confirmed with each quotation rather than published as a fixed figure.
- Packaging Option: Injection-molded plastic pallets available on request as an alternative to wooden pallets, subject to supplier capability and order size.
- Documentation Support: Import documentation support available. Available documents may include TDS, SDS, COA, origin documents and compliance declarations where applicable.
Technical & commercial reference
Caustic soda (sodium hydroxide) — how buyers specify and compare offers
Flakes and pearls are the same chemistry in different physical forms; the choice is driven by dissolution behaviour, dosing equipment and handling exposure rather than by purity alone.
Selection
How the right grade is chosen
- Physical form — pearls generally dissolve with less dusting than flakes, which affects operator exposure
- Purity and the chloride / carbonate limits the process tolerates
- Whether dissolution is manual or through automatic make-up equipment
- Packaging integrity, because the material is strongly hygroscopic
Specification
What to state in the enquiry
- NaOH assay and Na2CO3 / NaCl limits
- Iron content where product colour matters
- Physical form (flake / pearl) and bulk density
- Documentation required: TDS, SDS and batch COA
Procurement
Sourcing considerations
- Dissolution is strongly exothermic — confirm the site's make-up procedure before switching form
- Corrosive classification governs transport and storage; SDS review precedes ordering
- State assay, form and required documents in the enquiry
- Grade, specification, documentation, packaging, availability and delivery terms are confirmed against supplier documentation with each quotation.
Comparison
Comparing competing offers
- Cost per unit of NaOH delivered, not per kilogram of product
- Handling exposure and dust behaviour of the offered form
- Carbonate content, which rises with poor packaging or long exposure

About this product
Caustic Soda Flakes & Pearls (Sodium Hydroxide) — product overview
Anhydrous caustic soda (sodium hydroxide, NaOH) in flake and pearl forms for industrial use. Typical downstream applications include pulp and paper processing, industrial water neutralisation and chemical synthesis. UN-approved poly-bag packaging is used for transport. Because NaOH is a category-J bulk industrial chemical and reactive to moisture, packaging, storage guidance and shipping documentation are confirmed per shipment; SDS is provided against the specific grade and origin supplied. Purity, particle form (flake vs pearl) and batch COA are confirmed at quotation.
Document & COA status
- • TDS: Displayed properties are an Allzone technical reference; manufacturer documentation is available on request.
- • SDS: Safety data is subject to grade and supplier confirmation. One SDS does not necessarily apply to every grade or supplier.
- • COA: Certificate of Analysis is provided against the confirmed shipment, grade and batch. No stock, lead-time or regulatory claim is implied without written confirmation.
