Step 1: RFQ – Request the Supplier’s GRS 4.0 Scope Certificate Before Price Negotiation
Before you even discuss price per piece, ask for the supplier’s current GRS 4.0 Scope Certificate (SC). This document, issued by an IAF-accredited certification body (e.g., Control Union, SCS Global, Intertek), confirms that the mill is audited for the Global Recycled Standard across its entire operation. The SC must list the specific production site address, the scope of certification (e.g., “recycling, manufacturing, and trading of recycled polyester fiber and fabrics”), and the certificate number. Do not accept a photocopy of a certificate from a different factory – verify the site address matches your supplier’s registered address. A valid SC is the foundation for all subsequent claims; without it, any GRS claim on your throw is unverifiable. Verification method: Check the certifier’s online database (e.g., Control Union CertID, SCS Global CertSearch) to confirm the SC is active and matches the site.
On your RFQ, include a line item: “Supplier must provide a valid GRS 4.0 Scope Certificate issued within the last 12 months, covering the production site for 280gsm coral fleece fabric.” Also specify the minimum recycled content you require – typically 50% or more for GRS certification. For a 280gsm throw, the recycled content is usually 100% post-consumer recycled polyester (rPET) chips, but some mills blend with virgin to achieve specific handfeel or color targets. Clarify this upfront: “Recycled content: minimum 95% post-consumer rPET.” This avoids later disputes when the Transaction Certificate is issued.
A common pitfall: some suppliers present a Scope Certificate from Oeko-Tex or Ecocert. While these bodies are reputable for other standards, they are not IAF-accredited for GRS 4.0 chain-of-custody auditing. Only IAF-accredited certifiers (Control Union, SCS Global, Intertek, and a few others) can issue valid GRS SCs. If your supplier offers a non-IAF certificate, the claim will not hold at customs. Hard rule: Accept only SCs from IAF-accredited bodies for GRS 4.0.
Step 2: Sample Approval – Demand a GRS 4.0 Transaction Certificate for the Fabric Lot
Once you approve lab dips and handfeel samples, request a GRS 4.0 Transaction Certificate (TC) for the specific fabric lot used in your sample. The TC is a batch-level document that traces the recycled material from the recycler to the yarn spinner to the fabric mill. It must state the product name (e.g., “280gsm recycled polyester coral fleece”), the weight in kg, the recycled content percentage, and the certificate number linking back to the SC. The TC also shows the chain of custody: every entity that handled the material must be listed with their own SC numbers. If the TC shows a gap – for example, a yarn supplier like 'Yarn Co. Ltd.' without a valid SC, while the recycler 'Spinner Co. Ltd.' has one – the claim is broken. Verification method: Cross-reference each entity’s SC number against the certifier’s online database.
Your sample approval form should include: “GRS 4.0 Transaction Certificate for this fabric lot must be provided within 10 working days of sample approval.” Also specify that the TC must be issued by the same certification body that issued the SC. Some mills use different certifiers for different stages, which is acceptable as long as each is IAF-accredited. But a single certifier throughout simplifies your audit trail. For a 280gsm coral fleece throw, typical lot sizes are 500-1000 kg per color. Request the TC for the exact lot number that matches your production color.
The TC must include the buyer’s EORI number or VAT ID for EU customs compliance, not just the company name. If the TC lists only a trading company as the buyer, the chain of custody is broken for your own claim. Insist that your company appears as the consignee.
Step 3: Pre-Production – Verify the GRS 4.0 Logo Usage and Labeling Requirements
Before bulk production begins, confirm how the GRS logo will appear on your product and packaging. The GRS 4.0 standard requires that the logo be accompanied by the certification body’s name or logo, the certificate number, and a statement of recycled content (e.g., “Contains 100% recycled polyester”). The label must be approved by your certification body before printing. Many EU retailers require the GRS logo on the hangtag or a woven label sewn into the side seam. For a 280gsm throw, a woven label is more durable than a printed hangtag, but both are acceptable. Specify in your PO: “GRS 4.0 logo must appear on woven side seam label and on hangtag. Logo usage must comply with Textile Exchange guidelines. Supplier to submit label artwork for approval 30 days before bulk shipment.” Verification method: Request a PDF of the approved label from the certifier before production.
Also decide on the claim format. For EU retail, the most common is: “This product is made from 100% recycled polyester certified by [Certifier] under the Global Recycled Standard (GRS 4.0).” Some brands also include the percentage of recycled content on the front of the hangtag. Be aware that the GRS logo cannot be used on products that contain less than 50% recycled content. If your throw uses 100% rPET, you’re fine. But if you blend with virgin polyester for cost reasons, ensure the recycled percentage is clearly stated and verified.
Only IAF-accredited certification bodies (Control Union, SCS Global, Intertek) can approve GRS logo usage. Do not accept logo approval from non-IAF bodies like Oeko-Tex or Ecocert for GRS claims – their approval has no standing under the GRS 4.0 standard.
Step 4: Bulk Production – Request In-Process GRS 4.0 Documentation and Supplementary Lab Tests
During bulk production, request interim documentation: a GRS 4.0 Material Balance Report from the mill, showing the input of recycled chips versus output of finished fabric. This report is internal but should be available for your audit. Additionally, request supplementary quality test reports – while not part of GRS documentation, they are critical for EU retail acceptance. For a 280gsm coral fleece throw, typical targets: wash fastness at 4-5 for color change and staining (ISO 105-C06, 40°C, 30 min), and light fastness at 4 or higher (ISO 105-B02, xenon arc, 20 hours). These tests are not GRS-required but verify product durability. If the fabric fails these, the GRS claim is irrelevant – the product won’t sell. Verification method: Confirm the lab’s ISO 17025 scope includes the specific test methods (e.g., ISO 105-C06, ISO 105-B02) via the lab’s accreditation certificate.
Your PO should include: “Supplier to provide ISO 105-C06 and ISO 105-B02 test reports from an ISO 17025 accredited lab (accreditation body: A2LA for US-based labs, UKAS for UK-based labs) for the production lot. If an ISO 17025 accredited lab is unavailable, an equivalent lab with documented QA protocols and calibration records may be accepted upon prior written approval.” Also request a GRS 4.0 Transaction Certificate for the finished fabric at this stage, covering the entire production quantity. This TC will be the basis for your final claim. For a typical order of 5,000 throws (approx. 1,400 kg of fabric), the TC must cover the exact weight and product code.
The TC must include the buyer’s EORI number or VAT ID for EU customs compliance. Without this, customs may reject the recycled content claim.
Step 5: Final Shipment – Audit the GRS 4.0 Transaction Certificate Against the Packing List
Before shipment, request the final GRS 4.0 Transaction Certificate (TC) from the mill, covering the exact quantity of finished throws. Cross-check the TC against your packing list: the product description, weight, and number of pieces must match. The TC should also list the buyer (your company) as the consignee, including your EORI number or VAT ID for EU customs compliance. If the TC lists a different buyer or a trading company, the chain of custody is broken, and you cannot make a GRS claim to your retailers. For EU imports, the TC must be in English or include a certified translation. Keep the TC with your customs documentation; some EU customs authorities may request it to verify the recycled content claim. Verification method: Check the TC against the certifier’s online database to confirm it is valid and matches the SC.
Your final PO line item: “Supplier to provide final GRS 4.0 Transaction Certificate for the shipped quantity, referencing our PO number, within 5 working days of vessel departure. TC must list [Your Company Name] as the buyer, including our EORI number [insert number] or VAT ID [insert ID].” Also request a GRS Logo Usage Approval from your certification body if you plan to use the logo on your own packaging. Many EU retailers require this approval before listing the product as GRS certified. The entire process, from RFQ to final TC, typically takes 8-12 weeks for a 280gsm coral fleece throw order: 2 weeks for samples, 4 weeks for production, 2 weeks for testing and TC processing.
Regarding EU customs code 6301.40 (blankets and traveling rugs of synthetic fibers): recycled content claims do not automatically affect duty rates under this HS code. Duty rates are based on fiber type and construction, not recycled content. However, some EU member states may apply reduced VAT rates or preferential tariff treatment for recycled-content products under national green procurement policies. Verify with your customs broker whether any local incentives apply. The GRS TC is your evidence for any such claim.

Frequently Asked Questions
Can I accept a GRS Scope Certificate from Oeko-Tex or Ecocert? No. Only IAF-accredited certification bodies (Control Union, SCS Global, Intertek) can issue valid GRS 4.0 Scope Certificates. Oeko-Tex and Ecocert are not IAF-accredited for GRS chain-of-custody auditing. Accepting a non-IAF certificate will result in your GRS claim being rejected at EU customs.
Do I need ISO 105-C06 and ISO 105-B02 test reports for GRS certification? No. These are supplementary quality tests, not part of GRS 4.0 documentation requirements. However, most EU retailers require them for product acceptance. GRS only requires chain-of-custody documents (SC, TC, logo approval). We recommend including these tests in your PO to avoid retail rejection.
What if my supplier's Transaction Certificate lists a trading company as the buyer instead of my company? The chain of custody is broken. The TC must list your company as the consignee (with EORI/VAT ID) for you to make a valid GRS claim. If a trading company is listed, you cannot prove the recycled material reached your product. Request a corrected TC before shipment.
Does recycled content affect EU customs duty rates under HS code 6301.40? Generally, no. Duty rates under HS 6301.40 are based on fiber type and construction, not recycled content. However, some EU member states offer reduced VAT or preferential tariff treatment for recycled-content products under national green procurement policies. Check with your customs broker for local incentives. The GRS TC is your evidence for any such claim.
How long does the full GRS 4.0 certification process take for a 280gsm coral fleece throw order? Typically 8-12 weeks: 2 weeks for samples and TC, 4 weeks for bulk production, 2 weeks for testing and final TC processing, plus 2-4 weeks for logo approval if not done pre-production. Start the process early – logo approval alone can take 3-4 weeks from some certifiers.
