Quality, Materials & Testing

Documentation Readiness

Safety, social responsibility, and chemical compliance

Order documents should be checked by certificate holder, valid date, test scope, and product coverage before they are used in buyer files, retail listings, or private label documentation.

Textile safety	Verify certificate holder, product scope, and valid date before listing any claim.
Social responsibility	Use audit language only when the buyer has reviewed the current audit document.
Chemical compliance	Attach test reports by yarn, color, and order scope when required.
Organic or recycled yarn	Confirm chain-of-custody and material scope before using certification wording.
