How to check a clothing supplier's textile certificate

For OEKO-TEX STANDARD 100, check the number through the official Label Check, read the certificate's scope and confirm its connection to the material or garment you are buying. A valid number alone does not establish that your finished product is certified.

Textile swatches for a material sourcing decision

Begin with the exact claim

A supplier sending a certificate for fabric is making a different claim from supplying a certified finished garment. Before using that evidence in a Shopify listing or TikTok Shop product description, identify what you need to establish: the selected fabric, a component or the completed article.

OEKO-TEX describes STANDARD 100 as certification for textiles tested for harmful substances. It is not a general badge that establishes every environmental claim, working condition or aspect of garment quality.

Check the number at its source

Ask for a readable current certificate and the exact material or product reference. Navigate to OEKO-TEX's official Label Check, rather than relying on a supplier screenshot or a similar-looking website. Enter the certificate or label number and compare the result with the document provided.

Save the checking date and result with the document. If the number cannot be matched, do not guess from a logo. Ask the supplier or issuing institute to resolve it. A valid result still needs to be connected to the goods in your order.

Hohenstein's certificate guidance explains how the official check can help establish validity and scope. Where a reseller is involved, a different company name is a question to resolve, rather than automatic proof of fraud.

Do not promote a component certificate into a garment claim

A garment includes more than its main fabric. Its trims, thread, print and other components can affect the certification question. Hohenstein's STANDARD 100 guidance specifically distinguishes using pre-certified components within certification from labelling or marketing the finished product as certified.

If your evidence covers only the fabric, record that limited scope. Ask the issuer or responsible certification holder what is needed for the finished article and its intended use. Do not present the whole garment as certified merely because one input has a certificate.

These outcomes help organise a sourcing decision. They do not certify a supplier, replace testing or establish that a garment meets every requirement in every sales market.

Keep public wording within the evidence

Use the current OEKO-TEX labelling guide and obtain clarification where permission or scope is unclear. This guide does not grant permission to use a logo or approve market-specific advertising claims.

Keep the actual evidence beside the garment brief and the supplier decision. If a material changes, revisit whether the earlier evidence still applies rather than carrying its badge forward automatically.

Keep supplier evidence connected

The useful question is what the evidence supports for this garment.
