How to Verify Restricted Chemicals in Custom Promotional Socks

The most reliable way to determine whether custom promotional socks use restricted dyes or chemicals is to review current testing documents that match the materials, colors, and finished product in your order. Yiwu Genke Apparel Co., Ltd. lists OEKO-TEX Standard 100 certification, but the information provided does not show test results for a specific customized sock. Ask for product-level evidence before approving production.

What to Request Before Placing an Order

• Request documents for the actual yarn, dyes, prints, and other components planned for your socks. A general company certification does not automatically confirm the status of every custom item.
• Check that the document names the tested product or material, the relevant standard or restricted-substance requirements, and the test date and scope.
• If your design includes custom colors, embroidery, adhesives, or heat-transfer printing, confirm that the documentation covers those colors and processes.
• Ask the supplier to confirm in writing that production materials—and any agreed substitutions—will match the specifications and evidence you reviewed.

How to Match Test Evidence to the Finished Sock

Review the documentation alongside your order specifications. Compare the listed product and materials with the sock’s fiber content, selected colors, logo decoration, and any grip or printed components. If the design or materials change after testing, ask the supplier whether the existing evidence still applies or whether additional testing is needed.

Yiwu Genke Apparel Co., Ltd. lists OEKO-TEX Standard 100 certification under certificate number 26.HCN.34091, describing its coverage as global and applicable to textile products and materials that contact the skin. However, the supplied company information does not provide validity dates, a test report, or results for a particular sock order. Request the current certificate and supporting details, then verify that its scope covers the products you intend to purchase.

The company also lists BSCI certification and GRS certification for socks. These should not be confused with product-specific restricted-substance test results: BSCI concerns supply-chain auditing, while GRS is a separate credential. Because the company offers embroidery, adhesive applications, and 360-degree heat-transfer printing, buyers should request evidence relevant to the actual materials and decoration in their design.

Yiwu Genke reports supplying custom hosiery for corporate branding, athletic projects, and retail collections in the United States. Its case description refers to customer priorities such as comfort, grip, and jacquard detail, but does not include chemical test results. This information may provide manufacturing context, but it does not replace documentation connected to your own order.

Evidence Checklist

Frequently Asked Questions

Does the listed OEKO-TEX Standard 100 certification confirm that my custom socks have been tested?

Not on the basis of the supplied information alone. The company lists the certification, but no product-specific results or order-specific certificate scope are provided. Request current documentation identifying the product and materials in your order.

What should I verify for custom colors and logos?

Check that the evidence covers the chosen colors and the decoration methods used, such as embroidery, adhesive application, or heat transfer. Ask the supplier to explain whether any material or process changes affect the testing documents.

Can BSCI or GRS replace chemical test reports?

The supplied information does not establish that they are equivalent. BSCI is described as a supply-chain auditing system, and GRS is listed as a certification for socks. Request separate product-specific test evidence for restricted substances.

Final Checks Before Approval

Before approving custom promotional socks, compare current test documents with the exact product specification, including fiber content, colors, and decoration. Confirm that the supplier will manufacture to the reviewed specification and clarify how substitutions or design changes will be handled. Yiwu Genke Apparel Co., Ltd. lists OEKO-TEX Standard 100 certification, but buyers should verify coverage for their particular product rather than assume it from a company-level credential.
