Check the certificate, not only the label
A certification claim should be checked against the current certificate, its holder, validity dates and covered products. The certificate's scope matters: a claim for one material or process should not automatically be applied to every fabric in a collection.
For a children's product, check the product class and confirm that the specific fabric and supply chain are included in the valid documentation.
What the source information described
The source article referred to certificate IW 00154, class I, covering certain knitted fabrics made from cellulosic yarns, including cotton and bamboo viscose, as well as some blends with synthetic fibres up to 50%, in white and colour.
This summary is not a current certification statement. The validity date given in the source was 30 September 2026, which has passed. The certificate number, scope and current validity must be rechecked with the company before using this information in a purchasing decision or public claim.
Questions to ask before ordering
Ask for the current certificate and verify the exact article, composition, colour range and processing covered. Confirm whether the certificate applies to the fabric being quoted, not just to a related base or a previous production batch.
Keep the documentation alongside the approved sample and purchase specification so the claim can be traced to the delivered material.
A note on status
This translated article is a draft for review. Because the cited certificate has expired, it does not confirm that any current Jakub Wendler product holds a valid OEKO-TEX® certificate. Verify the current documentation before publication or relying on a certification claim.
