Key takeaway
If your textile, apparel, home textile, baby product, footwear, bag or pet product page uses claims such as OEKO-TEX, tested for harmful substances or skin-friendly, the first step is not to collect another supplier screenshot. Build a claim-to-evidence table that links the certificate number, product scope, material composition and customer-facing wording.
The OEKO-TEX STANDARD 100 page states that STANDARD 100 is a label for textiles tested for harmful substances, from yarn to finished product. It also states that every thread, button and accessory is tested against a list of over 1,000 harmful substances, and that harmful-substance limit values are reviewed at least once a year.
For sellers, this means the claim must match the evidence. Check whether the certificate is valid, whether it covers the current SKU, whether accessories are included, and whether the product page expands a harmful-substance test into organic, recycled, carbon-neutral or broad sustainability claims.
Three common mistakes
First, teams keep supplier screenshots but do not verify the certificate or label number. OEKO-TEX provides Label Check, so sellers should keep a verification record before using related claims.
Second, teams check only the main fabric and ignore trims. Threads, buttons, zippers, elastics, prints, fillings and care labels can all affect the claim boundary.
Third, teams use STANDARD 100 as a universal green label. It supports harmful-substance and textile-safety claims, but it does not automatically replace GOTS, OCS, GRS, RCS, FSC or carbon-neutral evidence.
A practical four-column table
Column 1: customer-facing claim.
List every OEKO-TEX, harmful-substance, skin-friendly or baby-use statement in product pages, short videos, hangtags, website pages and customer-service scripts.
Column 2: evidence file.
Add certificate numbers, Label Check screenshots, supplier certificates, material lists, test scopes and purchase batches.
Column 3: covered scope.
Check SKUs, colors, sizes, fabrics, trims, product classes and validity dates.
Column 4: action.
Keep the claim, collect more evidence, narrow the wording, delete exaggerated language, or route the claim to another standard such as GOTS, OCS, GRS/RCS, FSC or carbon-footprint evidence.
Green Ark (Shenzhen) Certification Co., Ltd. can support certification-path screening, supply-chain evidence lists and green-claim pre-checks for OEKO-TEX, GOTS, OCS, GRS, RCS, FSC, RWS, carbon neutrality and USDA Organic. The support is preparation and consulting work, not certificate issuance or a promise of certification outcome.
