How to Source CAS Products from China

A practical sourcing checklist for overseas buyers requesting CAS-number chemical quotations from China.

CAS-based sourcing is the fastest way to avoid confusion between similar chemical names. A useful inquiry should be short, specific and document-focused.

Inquiry checklist

  • CAS number and English product name
  • Purity or specification target
  • Required quantity and sample quantity
  • Destination country or port
  • COA, SDS, TDS or packing requirements

How to compare quotes

Do not compare only unit price. Review MOQ, batch availability, lead time, document support, packaging and shipping method before confirming an order.
