GRS vs RCS Certification: What's the Difference? How Should Cross-Border Sellers Choose? (2026 Comparison Guide)
One-Sentence Summary
GRS is the premium version; RCS is the entry-level version. Beyond verifying recycled material content, GRS also audits factory environmental management, social responsibility, and chemical management. RCS only checks one thing: how much recycled material you use.

FAQ
Q: Can I start with RCS and upgrade to GRS later?
A: Yes. RCS audit data can be reused for GRS, but additional environmental and social responsibility audits are required.
Q: Can RCS also get the Amazon CPF green badge?
A: Yes, but requires recycled content ≥50% (much higher than RCS's basic 5% threshold).
Q: Which has a shorter certification timeline?
A: RCS is faster (2-4 weeks vs 4-8 weeks) because the audit scope is smaller.
Q: Can traders (without factories) apply?
A: Both GRS and RCS support trader applications — online audit only.
Q: Is certification cost a one-time expense?
A: No. Certificates are valid for 1 year, requiring annual renewal and audit.
