The Global Recycled Standard (GRS) is the most widely recognized certification for recycled content in textiles. But a certificate alone does not guarantee that the fabric you receive is genuinely recycled. Certificate fraud, expired scopes, and scope mismatches are real problems in the supply chain. This guide walks through the specific checks that fabric buyers need to perform to verify that a GRS certificate is valid, current, and actually covers the product being sold.<\/p>\n

Why GRS Verification Is Not as Simple as Checking a PDF<\/h2>\n

A GRS certificate is issued by an accredited certification body after an audit of the mill or facility. The certificate lists the company name, address, scope of certification, product categories, and validity period. However, several things can go wrong. The certificate may have expired. The company name on the certificate may not match the invoicing entity. The product category may cover recycled polyester but not the specific recycled wool blend you ordered.<\/p>\n

\"GRS<\/p>\n

Since 2021, all valid GRS certificates are registered in the Textile Exchange’s public database. This is your first verification step, and it takes less than two minutes.<\/p>\n

Step 1: Check the Textile Exchange Certificate Database<\/h2>\n

Go to the Textile Exchange’s certificate search page and enter the certificate number from the document your supplier provided. The database will show the company name, status (active, suspended, or withdrawn), valid-from and valid-to dates, and the scope of certification including which materials and processes are covered.<\/p>\n

If the certificate number does not appear in the database, it is not valid. Period. Do not accept explanations about database delays or system updates. The Textile Exchange updates the database within 30 days of certification, and any legitimate certificate will appear within that window.<\/p>\n

Step 2: Verify the Scope Covers Your Product<\/h2>\n

For pricing and sampling, browse GRS-certified ready stock fabrics<\/a> from the Fursone team.<\/p>\n

Even a valid certificate may not cover the specific product you are buying. The scope section of the certificate lists the material types (recycled polyester, recycled nylon, recycled wool, etc.) and the processes covered (spinning, weaving, knitting, dyeing, finishing). If your supplier is selling you GRS-certified recycled wool tweed but the certificate scope only lists recycled polyester and spinning, the certificate does not cover your product.<\/p>\n

\"Verifying<\/p>\n

Pay special attention to the subcontractor list. Many mills outsource dyeing or finishing to other facilities. If the subcontractor is not listed on the certificate or does not have its own GRS certification, the chain of custody is broken and the final fabric cannot legitimately carry the GRS label.<\/p>\n

Step 3: Check the Transaction Certificate<\/h2>\n

For each shipment, the certified supplier should issue a Transaction Certificate (TC). The TC is a document that traces a specific batch of material from the certified supplier to you, the buyer. It includes the TC number, date, product description, quantity, GRS percentage, and the certification body that issued it.<\/p>\n

The TC is your proof that the specific rolls you received are covered by the supplier’s GRS certification. Without a TC, you cannot make any recycled content claims on your own product labels or marketing materials. Request the TC before making final payment, and verify that the product description matches your purchase order exactly.<\/p>\n

Step 4: Cross-Reference the Certification Body<\/h2>\n

GRS certificates are issued by certification bodies accredited by Textile Exchange. As of 2026, the major accredited bodies include Control Union, CU; Intertek; SGS; Bureau Veritas; and ICEA. If your supplier’s certificate was issued by an organization not on the Textile Exchange’s accredited list, the certificate is not valid under the GRS program.<\/p>\n

Red Flags That Indicate Certificate Problems<\/h2>\n

Watch for these warning signs. The supplier hesitates to provide the certificate number or TC. The certificate PDF shows signs of editing. The company name on the certificate differs from the name on the invoice. The certificate scope lists only raw materials but not the finished fabric type you are buying. The validity period has expired or is about to expire. The certification body is unknown or not accredited.<\/p>\n

At Fursone, every GRS-certified product ships with a copy of the current certificate, the TC for that shipment, and a link to the Textile Exchange database entry. We maintain this documentation because our buyers need it for their own compliance with EU and US textile labeling regulations.<\/p>\n
