Certifications are proxy evidence of process maturity:

• ISO 9001 – documented quality management system;
• BSCI / SEDEX / WRAP – audited social and labour compliance;
• GRS / RCS – verified recycled-content claims (critical for recycled-poly activewear);
• OEKO-TEX / bluesign – restricted substance and chemical safety assurance.

Pair certificates with your own QC records—a badge is a starting point, not a substitute for inspection.
