GRS/RCS/OCS/GOTS Recycling & Organic Certification Complete Guide: One Table to Understand Four Major Textile Certifications
I. Introduction: Sustainable Certifications in Textiles Enter the "Standard Era"
In 2025-2026, global demand for sustainable textile certifications is growing at unprecedented speed. On one hand, the EU has introduced regulations like EUDR and CSRD requiring higher standards of supply chain transparency and sustainability for imported textiles; on the other hand, international brands represented by Nike, Adidas, H&M, and Zara have successively required their suppliers to hold GRS, GOTS and other sustainable certifications.
For cross-border e-commerce sellers, these certifications are not only "tickets" to enter major brand supply chains but also core pathways to obtain Amazon's CPF green badge — both GRS and GOTS certifications can directly link to the CPF green badge, bringing additional search weight and traffic bonuses to products.
However, the four certifications — GRS, RCS, OCS, GOTS — have similar names and overlapping standards, easily confusing sellers encountering them for the first time. This article provides a systematic comparative analysis to help sellers clarify everything at once.
II. Core Differences Among the Four Certifications
2.1 Certification Positioning Overview
| Dimension | GRS | RCS | OCS | GOTS |
|---|---|---|---|---|
| Full Name | Global Recycled Standard | Recycled Claim Standard | Organic Content Standard | Global Organic Textile Standard |
| Certification Target | Textiles with recycled materials | Products with recycled materials | Textiles with organic fibers | Full-process organic textiles |
| Recycled/Organic Content Threshold | ≥20% | ≥5% | ≥5% | ≥70% (organic natural fibers) |
| Covers Social Responsibility | Yes | No | No | Yes |
| Covers Chemicals | Yes | No | No | Yes |
| Covers Environmental Mgmt | Yes | No | No | Yes |
| Issuing Body | Textile Exchange accredited | Textile Exchange accredited | Textile Exchange accredited | GOTS accredited bodies |
| CPF Green Badge Eligible | Yes | No (not CPF-supported) | No (specific scenarios only) | Yes |
2.2 GRS (Global Recycled Standard): Most Widely Applied Recycling Certification
GRS is currently the most widely used recycled material certification in cross-border e-commerce. Its core requirement is recycled material content ≥20%, with certification scope also covering:
- Social Responsibility: Compliance with ILO core conventions
- Chemical Management: Restrictions on hazardous chemical use
- Environmental Management: Wastewater treatment, energy consumption, waste management, etc.
GRS certification applies to textiles containing recycled polyester (rPET), recycled cotton, recycled nylon, recycled wool, etc. For Amazon sellers, GRS certification can not only be used to apply for CPF green badge but also allows adding "GRS Certified" in product titles and descriptions to enhance consumer trust.
Nike Supply Chain Policy: Since 2024, Nike has required its finished product suppliers to hold at least one of GRS or GOTS certification. This requirement is expected to extend to all fabric suppliers by 2027.
2.3 RCS (Recycled Claim Standard): Simplified GRS
RCS can be understood as a "simplified version" of GRS. Its core requirement is verifying recycled material content (≥5%), without involving social responsibility, chemical management, or environmental management.
RCS is suitable for:
- Products with lower recycled content (5%-19%), insufficient for GRS
- Sellers needing only recycled material claims without full social/environmental audits
- Non-textile products (e.g., plastic products) requiring recycled content verification
Note: RCS certification cannot directly link to Amazon CPF green badge — currently CPF-recognized recycling certifications are primarily GRS. Therefore, if the goal is CPF green badge, prioritize GRS (provided recycled content reaches 20%).
2.4 OCS (Organic Content Standard): Focused on Organic Fiber Content
OCS certification verifies organic fiber content (≥5%) in products, suitable for textiles containing organic cotton, organic linen, organic wool and other organic natural fibers.
OCS has two levels:
- OCS 100: 100% of natural fibers used are organic
- OCS Blended: At least 5% of fibers are organic
Unlike GOTS, OCS only focuses on organic fiber traceability and content verification, without requirements for chemical use, wastewater treatment, or social responsibility in production. Thus OCS certification costs and difficulty are lower than GOTS, suitable as an "entry-level" choice for suppliers not yet ready for full organic production conditions.
However, OCS has relatively lower weight in Amazon's CPF green badge system — CPF currently recognizes GOTS and GRS more. If budget and conditions allow, prioritizing GOTS certification is recommended.
2.5 GOTS (Global Organic Textile Standard): The "Gold Standard" for Organic Textiles
GOTS is the globally recognized highest standard in organic textiles. Unlike OCS which only verifies "organic content," GOTS certification covers the entire process from raw material harvesting to finished product marketing, including:
- Organic Fiber Requirements: At least 70% natural fibers are organic (for "organic" label) or at least 95% (for "GOTS Organic" label)
- Environmental Management: Wastewater treatment systems, energy and water management
- Chemical Restrictions: Explicitly prohibits and restricts hundreds of hazardous chemicals
- Social Responsibility: Free employment choice, freedom of association, no child/forced labor, occupational health & safety, etc.
GOTS certification can display in Amazon's CPF green badge system, and due to GOTS's extremely high global recognition and credibility, products with this certification command significantly stronger premium pricing power with consumers.
GOTS Version 7.0 (released 2024) added carbon footprint, marine microplastics and other indicator requirements, further enhancing certification comprehensiveness.

| 5%-19% recycled content | RCS | Lower threshold, meets recycled claim needs |
| ≥5% organic fiber, limited budget | OCS | Entry-level organic certification |
| ≥70% organic fiber, premium positioning | GOTS | Gold standard certification, strong premium power |
| Contains both recycled + organic materials | GRS + OCS/GOTS | Combinable certifications, one plan covers all |
V. FAQ
Q: I already have GRS certification, do I still need GOTS?
A: Depends on your product materials and target market. GRS targets recycled materials, GOTS targets organic fibers — if your product uses both recycled polyester (GRS-applicable) and organic cotton (GOTS-applicable), you need both certifications. Brands often require specific certifications based on material processes. For example, Nike may simultaneously require suppliers to hold GRS (for recycled polyester fabrics) and GOTS (for organic cotton fabrics).
Q: RCS can't link to CPF green badge — is it still valuable?
A: Yes, but not at the CPF green badge level. RCS value lies in: (1) Meeting brand client supply chain compliance requirements (many brands accept RCS as recycled claim); (2) "Contains X% recycled materials" claims on packaging and marketing require RCS support; (3) Best compliance choice when recycled content hasn't reached 20%. If the goal is only CPF green badge and recycled content reaches 20%, go directly with GRS.
Q: I'm a trader without my own factory — can I get GRS/GOTS certification?
A: Yes, but upstream supplier cooperation is required. Traders can obtain GRS or GOTS certification through: (1) If upstream suppliers are already certified, you can join their certification system via "Supply Chain Certification" (SC Certificate); (2) If upstream suppliers aren't certified, their factories need auditing by certification bodies. Professional certification service providers like GreenArk can help you map supply chain relationships and design optimal certification pathways.
Q: What did GOTS 7.0 add? How does it affect existing certified companies?
A: GOTS 7.0 (released March 2024, mandatory from March 2025) mainly added/strengthened: (1) Carbon footprint tracking — companies must record and report energy consumption and carbon emission data to GOTS; (2) Marine microplastics — synthetic fiber products must take measures to reduce microfiber shedding during washing; (3) Due diligence — companies must conduct due diligence on human rights and environmental risks. Existing certified companies will be audited against 7.0 standards during annual renewal; it's recommended to understand new requirements in advance and prepare compliance.
