Who uses this page

Target buyers

  • Concrete admixture manufacturers
  • Ready-mix concrete additive distributors
  • Construction chemical importers in Saudi Arabia and GCC markets
  • Dry mortar and grouting material formulators
  • Floor hardener and self-leveling compound producers
  • Industrial chemical sourcing teams requiring batch-level documentation
Before matching

Documents to check

  • CAS number, grade, assay, and impurity profile
  • SDS, COA, TDS, HS code, and transport classification
  • Destination-market import documents before supplier matching
Package and route

Packing notes

  • Listed packing: 25 kg plastic bag or woven fabric bag with plastic inner liner
  • Confirm whether bags are moisture-resistant and suitable for sea freight to Saudi Arabia or GCC destinations
  • Ask whether palletizing, shrink wrapping, container loading quantity, and FCL/LCL options are available
  • Confirm batch labeling details, production date, shelf-life marking, and traceability on each bag
  • Check whether sample packing and commercial packing are from the same production grade
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

  • Raw material for high-range water-reducing admixture formulations
  • Concrete admixture applications requiring improved dispersion of cement particles
  • Mortar, plastering, grouting, and self-leveling compound additive sourcing
  • Projects where sodium sulfate and chloride limits must be checked against concrete durability requirements
  • Construction chemical distribution where export packing and documentation readiness are important
How we compare

Sourcing options

  • Request a documented sample lot before commercial order
  • Compare low-sodium sulfate and standard SNF grades from the same supplier
  • Source by CAS 9084-06-4 plus performance specification rather than trade name alone
  • Use third-party lab verification for chloride, Na2SO4, moisture, pH, and solid content before bulk shipment
  • Ask for Saudi Arabia-ready export documents and confirm import requirements with the buyer's broker
  • Consider full-container procurement if monthly demand aligns with listed 5000 ton/month production capacity
Human review

Compliance notes

  • Request COA matching the offered batch, SDS, TDS, packing list, commercial invoice, and country-of-origin documentation before shipment
  • Confirm CAS 9084-06-4 and HS code 3824401000 with supplier documents and local import broker review
  • Check whether the product is classified as dangerous goods for the proposed transport route; do not rely only on marketplace listing text
  • For Saudi Arabia imports, buyer should verify SASO/SABER, customs, construction chemical, and end-use documentation requirements with local compliance parties
  • Confirm chloride, sodium sulfate, moisture, and insoluble/ash-related limits against the buyer's concrete admixture specification
  • Ask supplier whether third-party pre-shipment testing by SGS, BV, Intertek, or equivalent can be arranged
  • No regulatory clearance, import approval, or application performance guarantee should be assumed from the listing alone
