Industrial Grade Synthetic Iron Oxide Pigments for Export

Buyer-facing sourcing candidate for synthetic iron oxide pigments supplied in multiple colors for industrial applications. Key checks should focus on confirming the exact CAS/chemical identity for each shade, grade code, Fe2O3 or Fe3O4 basis, tinting strength, mesh residue, water-soluble salts, moisture, pH range, oil absorption, color difference, packing format, COA availability, and export document readiness before RFQ confirmation.

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

  • Coloring concrete, cement products, paving blocks, and floor tiles
  • Industrial paint and architectural coating pigmentation
  • Plastic, resin, and rubber coloration where inorganic pigment stability is required
  • Ceramic and building material coloration
  • Printing ink and paper coloration after application-specific testing
  • General industrial pigment distribution for overseas buyers
How we compare

Sourcing options

  • Bulk industrial grade synthetic iron oxide pigment by shade code
  • 25 kg bag export packing with palletized shipment
  • Sample-first qualification before bulk order
  • COA/SDS/TDS-supported RFQ for importer compliance review
  • Third-party inspection or lab test before shipment
  • Multi-color consolidated order subject to shade availability and MOQ
Human review

Compliance notes

  • Request current COA matching the production batch and exact shade code
  • Request SDS in buyer-required language and format before booking shipment
  • Confirm HS code; source page lists HS Code 28211000
  • Confirm whether the product is classified as dangerous goods for the destination route; many iron oxide pigments are commonly shipped as non-DG, but classification must be document-based
  • Confirm CAS number, EINECS, formula, and pigment identity for each color, especially mixed shades such as green, blue, brown, and orange
  • Check heavy metals, soluble salts, moisture, particle size, and color difference against the buyer’s application standard
  • For coatings, plastics, concrete, ceramic, leather, ink, paper, or textile use, confirm application-specific impurity limits and dispersibility expectations
  • Supplier claims import/export rights and quality assurance on the platform; buyer should still verify business license, export records, and third-party inspection acceptance

Questions to confirm
  • Which exact color and grade code are required, such as Red 130, Yellow 313, Black 722, or Green 835?
  • Is the required chemical identity Fe2O3, Fe3O4, or a blended/mixed pigment system?
  • Can you provide a recent COA for the selected grade and a retained-sample policy for shipment lots?
  • What are the guaranteed values for tinting strength, ΔE, residue on 325 mesh, water-soluble salts, moisture, pH, and oil absorption?
  • Are heavy metal limits available for lead, arsenic, cadmium, mercury, chromium, and other restricted elements?
  • Is the material suitable for the buyer’s target application, such as concrete, coatings, plastics, ceramics, rubber, ink, or paper?
  • Can the supplier provide SDS, TDS, COA, packing list, commercial invoice, certificate of origin, and any destination-specific documents?
  • What is the confirmed HS code and DG/non-DG transport classification for the shipment route?
