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

  • Source-listed transport package: carton
  • Source-listed specification: 10 kg/bag and 25 kg/bag
  • Confirm inner liner, moisture barrier, palletization, carton dimensions and net/gross weight
  • Request export packing photos and pallet loading quantity for FCL/LCL planning
  • Confirm shelf-life statement and storage condition wording for documentation only, without relying on handling instructions
  • Ask whether sample quantities are available and whether sample COA matches bulk 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

  • EVA coloration trials where heat resistance and migration performance must be verified
  • Solvent or water-based ink formulation screening, subject to compatibility testing
  • Plastic masterbatch and compound color matching after dispersion and processing validation
  • Industrial coating or printing applications requiring PR 53:1 shade comparison
  • Distributor sample qualification before bulk pigment sourcing
How we compare

Sourcing options

  • Request sample with COA and compare against current approved PR 53:1 standard
  • Ask supplier for EVA-specific grade confirmation due to listing inconsistency with ink application fields
  • Source by CAS and Pigment Index rather than color name only, as Golden Red C may vary by supplier
  • Consider dual-sourcing from audited pigment manufacturers with matching shade and strength data
  • Use third-party pre-shipment testing for heavy metals, shade, tinting strength and moisture before first bulk order
  • Confirm Incoterms, export packaging and non-DG/DG statement before price comparison
Human review

Compliance notes

  • Verify CAS No. 5160-02-1 and Pigment Red 53:1 identity across COA, SDS, TDS, label and customs documents
  • Request current SDS in GHS format and destination-language version where required
  • Request TDS, COA, RoHS/REACH SVHC statement, heavy metals report and migration test report where relevant to plastics, EVA or consumer product applications
  • Because PR 53:1 is a barium-containing lake pigment, request soluble barium and total heavy metal data, including Pb, Cd, Hg, Cr(VI), As and other buyer-specified limits
  • Confirm whether the product is classified as dangerous goods for sea/air/road transport and request UN number/class/packing group statement if applicable
  • Check destination-market restrictions for pigments used in toys, food-contact materials, cosmetics, footwear, packaging or consumer goods before use approval
  • Supplier audit claims and third-party audit references should be independently verified before onboarding
  • No regulatory compliance guarantee should be assumed from marketplace text; buyer should rely on signed supplier declarations and batch documents
