For brands committed to recycled materials and responsible production, partnering with a GRS certified clothing manufacturer ensures credibility, traceability, and regulatory readiness. To help you identify reliable partners, we’ve listed the top 10 clothing manufacturers with GRS certification in this writing below.
What Is GRS Certification? Key Benefits of GRS-Certified Manufacturers for Brands
The Global Recycled Standard (GRS) is an international, voluntary certification that verifies recycled content in products and ensures responsible manufacturing practices throughout the supply chain. Managed by Textile Exchange, GRS checks recycled material claims, traceability (chain of custody), environmental and social standards, and chemical restrictions. It is designed for products containing at least 20% recycled content, with 50% required for on-product labeling, helping brands ensure transparency from raw material to finished product.
Key Benefits of GRS-Certified Manufacturers for Brands:
- Credible and Verifiable Sustainability Claims: GRS certification provides independent, third-party verification to ensure that recycled content claims are accurate and trustworthy. This helps brands avoid misleading sustainability messaging and eliminates the risk of greenwashing. With clear documentation and audits, brands can confidently communicate their environmental commitments to consumers and stakeholders.
- Full Supply Chain Traceability and Transparency: GRS requires a strict chain-of-custody system supported by Transaction Certificates (TCs), allowing materials to be traced from recycled raw inputs to finished products. This transparency ensures that recycled materials are not mixed with virgin fibers without declaration. As a result, brands gain greater control and visibility across their supply chains.
- Stronger Brand Reputation and Consumer Trust: As consumers increasingly prioritize sustainability, GRS-certified products signal credibility and responsibility. The certification helps brands stand out in competitive markets by demonstrating genuine environmental action rather than marketing claims alone. Over time, this builds long-term trust, brand loyalty, and stronger relationships with conscious consumers.
- Compliance with Environmental and Social Standards: GRS-certified manufacturers must comply with strict environmental requirements, including chemical restrictions, wastewater management, and responsible resource use. The standard also includes social criteria based on international labor norms, covering worker safety, fair wages, and the prohibition of child or forced labor. This supports ethical and responsible production practices.
- Regulatory Readiness and Risk Mitigation: Working with GRS-certified manufacturers helps brands align with growing ESG expectations and sustainability regulations, particularly in the EU and North America. The certification reduces risks related to false claims, supply chain non-compliance, and reputational damage. It also supports long-term business resilience as regulatory scrutiny continues to increase.

FAQ
How can I verify if a factory’s GRS certificate is authentic?
You can verify a GRS certificate by checking the Textile Exchange GRS database (official website) where all valid certifications are listed. Each certificate has a unique certificate number and expiry date. Additionally, request the factory to provide a Transaction Certificate (TC) for specific production orders, which proves the recycled content and traceability of the materials.
Do factories with GRS certification charge higher prices?
Typically, GRS-certified factories may have slightly higher costs due to the additional auditing, compliance processes, and traceability systems required. However, the price difference is often reasonable, especially when compared to the benefits of verified sustainability, transparency, and market value for your products.
Which brands or product lines usually use GRS-certified materials?
GRS is often preferred by brands that focus on sustainable and eco-conscious collections, such as athleisure, activewear, outerwear, denim, T-shirts, and sweaters. Premium, mid-range, and lifestyle brands that market eco-friendly, recycled-content garments prioritize GRS to build credibility with environmentally conscious consumers.
