Do GRS, OEKO-TEX®, RCS, and GOTS certifications expire or require annual renewal?

Yes. Most certifications require annual renewal and regular audits (often yearly) to remain valid. Brands should confirm certification validity at the time of production/shipment and keep documentation linked to production dates for retailer checks.
