Do you accept third-party testing or inspection?

Yes — we cooperate with independent labs and inspection agencies for sampling, testing and verification against your specification.

VerificationResults compared with our COA and agreed spec
Pre-shipmentInspection before loading, per your checklist
We provide the samples, documents and site access needed; the agency runs the analysis independently. Third-party reports are issued by the agency and can be used for your customer or regulatory documentation.

Send your agency and test scope, and we will arrange sampling and coordinate the timeline.
