BSCI and OEKO-TEX: Why Certifications Matter for Underwear Sourcing
BSCI and OEKO-TEX are the two most important certifications for underwear sourcing from China. BSCI verifies ethical factory conditions (fair wages, no child labor). OEKO-TEX tests every fabric component for over 1,000 harmful substances. Both are held by the production sites used on your order; current reports are shared at quotation stage.
When sourcing underwear from China, certifications are your brand’s insurance policy. BSCI and OEKO-TEX are the two most important credentials for European and global buyers. Here’s why they matter and what they actually verify.

OEKO-TEX Standard 100: Chemical Safety
OEKO-TEX tests every component of a finished product — fabric, thread, elastic, buttons, zippers — for over 1,000 harmful substances. Products are classified by skin contact intensity, with Class I (baby) being the strictest. All Unitex underwear fabrics are OEKO-TEX certified.

Buyer Questions
MOQ, lead times, certification and trading terms
Two reasons: they evidence the claims a brand makes to its own customers, and they are checkable. amfori BSCI covers social compliance at the producing site while OEKO-TEX Standard 100 covers harmful-substance testing for the article, and between them they answer the questions buyers are most often asked. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
The partner factories hold them. A sourcing partner coordinates the relationship and verifies the documents, but the certificate belongs to the entity and site named on it — which is why the scope is read rather than the cover. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
By number, on the issuing body's own database, and then read for scope and validity. A genuine document covering a different site or a lapsed period does not support the claim being made with it. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
It reflects how the article is used. Class I applies to articles with direct skin contact for babies and children, which is why the children's category confirms the class explicitly rather than inheriting one from an adult line. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
Only the two above are declared. Any further requirement is confirmed per order rather than assumed, which keeps the claim accurate and avoids attributing a certificate to the wrong site or article. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
Whenever the producing site changes, and against the validity period otherwise. Certificates expire and renewal is not automatic, so a verification is a point-in-time check rather than a permanent status. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).
