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

  • Drilling fluid defoamer candidate where a nonionic milky liquid additive is specified
  • Industrial antifoam formulation screening for systems requiring quick foam knockdown
  • Coating or ink additive sourcing where buyer must validate compatibility through internal lab testing
  • Distributor stock item for industrial defoamer portfolios subject to local compliance review
How we compare

Sourcing options

  • Request lab sample with matched COA before bulk RFQ
  • RFQ for 800 kg MOQ in 25 kg drums, 200 kg drums, or IBC packing
  • Ask for India shipment quotation under FOB China port and CIF India port terms
  • Compare AT-930 against existing defoamer benchmark by pH, viscosity, solid content, active system, and foam knockdown test method
  • Request export documentation pack before payment milestone
Human review

Compliance notes

  • Request current COA, SDS, TDS, specification sheet, and commercial invoice/packing list drafts before order confirmation
  • Confirm exact product composition disclosure level available for importer compliance review, including silicone/polyether or other active system if applicable
  • Verify whether the product is classified as dangerous goods for sea and air transport; obtain non-DG certificate if applicable
  • Check India import requirements against HS Code 34029000 and the declared chemical identity before shipment
  • Supplier claims ISO 9001:2015 quality management certification; request certificate copy and scope confirmation
  • Do not rely on marketplace CAS text alone; confirm CAS, grade, and formulation identity directly with the manufacturer
  • Confirm REACH/RoHS/food-contact or other sector-specific documents only if required for the buyer's end-use; no regulatory guarantee should be assumed from the listing
