How we compare
Sourcing options
Request a 25 kg sample or pilot lot with COA and SDS for formulation screening
Place RFQ for 1 MT MOQ with confirmed specification and export document package
Ask for 10 MT+ pricing with palletized packing and batch retention agreement
Consider third-party inspection or lab confirmation before container shipment
Compare supplier data against alternative China coating additive suppliers for CAS, grade, rheology performance, and document readiness
Human review
Compliance notes
Request current SDS, COA, TDS, product specification, and transport classification before purchase
Confirm whether the product is classified as dangerous goods for the intended transport route and destination jurisdiction
Check HS code, export documents, country-of-origin statement, and any destination registration requirements before shipment
CAS number and formula presentation on the source page appear inconsistent in formatting; verify identity directly with supplier documents
No regulatory approval or import clearance should be assumed from marketplace listing data
For overseas buyers, confirm REACH, TSCA, UK REACH, K-REACH, IECSC, or other inventory status only through supplier declaration and independent compliance review as applicable
