Certified Quality. Verifiable at Every Step.
International buyers choose Changlian because our certifications aren't badges — they're embedded into our production workflow. GRS (Global Recycled Standard) certification covers our recycled nylon and polyester supply chain, providing the chain-of-custody documentation your sustainability team needs for consumer-facing claims. Our Oeko-Tex dyeing partnerships ensure no harmful substances enter your fabric at the finishing stage.
We maintain a live certification dashboard shared with each active client, so your compliance team always has access to up-to-date scope certificates, test reports, and supplier declarations — without chasing emails.
