Who uses this page

Target buyers

  • Food and beverage manufacturers requiring preservative raw materials
  • Ingredient distributors sourcing sodium benzoate in export-ready packing
  • Contract manufacturers needing documented food-additive inputs
  • Procurement teams comparing CAS 532-32-1 suppliers from China
  • Private-label or OEM buyers requiring customized labeling and packing
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 transport package: 25 kg and 200 kg formats
  • Listed specification: 25 kg/drum or 200 kg/drum
  • Page also mentions 1 kg aluminum foil bag, 25 kg drum/bag, 1 L bottle, 25 L drum, and 200 L drum as general packaging options; confirm which are applicable to sodium benzoate powder
  • OEM labeling and customer-specific packing are stated as available; confirm export carton, pallet, marking, and label language requirements
  • Request packing photos, net/gross weight, pallet dimensions, and moisture-protection details for sea or air shipment
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

  • Food preservative raw material qualification where permitted by local regulations
  • Beverage, condiment, pickle, and sauce production supply chain evaluation
  • Personal care or pharmaceutical excipient sourcing review where specifications match buyer requirements
  • Distributor stock replenishment for sodium benzoate powder
  • Incoming QC comparison against approved vendor specifications
How we compare

Sourcing options

  • Request 25 kg drum or bag quotation with batch COA and food-grade specification
  • Request 200 kg drum quotation for larger distributor or factory orders
  • Request sample with matching COA before bulk purchase
  • Ask supplier to quote both food-grade and industrial-grade options separately if available
  • Compare against alternate suppliers using CAS, assay, impurity limits, packing, lead time, and document readiness
Human review

Compliance notes

  • Verify CAS 532-32-1 against COA, SDS, invoice, and product label
  • Request food-grade basis documentation if the intended use is food or beverage manufacturing
  • Confirm applicable standard such as FCC, USP, BP, EP, GB, or customer-specific specification, if required by destination market
  • Check impurity profile including assay basis, moisture/loss on drying, acidity/alkalinity, heavy metals, chloride, sulfate, arsenic, lead, and related organic impurities as applicable
  • Request recent batch COA, SDS, allergen/GMO statement if relevant, country of origin, and traceability documents
  • Do not rely on page statements as regulatory approval for the buyer's destination market; buyer should verify import, labeling, and food-additive requirements locally
  • Confirm DG classification and export shipping status with current SDS and freight forwarder; sodium benzoate is commonly shipped as non-DG, but shipment documents should be checked
  • The page lists EINECS as 532-32-1, which appears inconsistent because that field normally differs from CAS; request corrected regulatory identifiers
