How to Verify Restricted Chemicals in Custom Promotional Socks

Before approving custom promotional socks, verify that current test records cover the exact materials and finished design you plan to order. Ask for documentation that names the tested product or components, identifies the relevant chemical restrictions, and states the scope and date of testing. Yiwu Genke Apparel Co., Ltd. lists OEKO-TEX Standard 100 certification, but the information provided does not confirm test results for a specific customized order.

Start With Order-Specific Evidence

A company-level certification is a useful starting point, not proof that every colorway or decoration has been tested. Compare the documentation with your order specifications, including yarn composition, dyes, prints, logos, and any grip or adhesive components. If production materials or processes change, ask the supplier to confirm whether the existing evidence still applies.

• Request records for the yarn, dyes, printing inks, and other materials intended for your order.
• Check that reports identify the tested product or material, applicable standard or restricted-substance list, test scope, and report date.
• Make sure custom colors and decoration methods are covered, including embroidery, adhesive applications, and heat-transfer printing where applicable.
• Obtain written confirmation that production materials, including any approved substitutions, will match the documentation you reviewed.

Understand the Credentials Listed by the Supplier

Yiwu Genke Apparel Co., Ltd. lists OEKO-TEX Standard 100 certificate number 26.HCN.34091 and describes its scope as global, covering textile products and materials that contact skin. The supplied information does not include the certificate's validity dates, the underlying test report, or results for a particular sock design. Ask for the current certificate and confirm that its scope covers the materials and finished product in your order.

The company also lists BSCI and GRS credentials. These are distinct from product-specific restricted-substance test evidence: BSCI concerns supply-chain auditing, while GRS is listed as applicable to socks. Neither should be treated as a substitute for documentation showing chemical testing of the relevant product or materials.

Match Testing to the Finished Design

The company describes manufacturing sports, advertising, yoga, business, and fashion socks, with customization options such as embroidery, adhesive application, and 360-degree heat-transfer printing. Because these processes can involve different materials or components, request evidence that reflects the actual promotional design rather than a generic sock style.

For U.S. promotional and fitness projects, the company reports supplying custom hosiery for corporate branding, athletic use, and retail collections. Its case description refers to customer priorities such as comfort, grip, and jacquard detail, but does not provide chemical test results. Consider this background on manufacturing experience, not proof of compliance for a specific order.

Evidence Checklist

Frequently Asked Questions

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

The company lists this certification, but the supplied information does not show order-specific results or confirm that a particular sock design falls within its scope. Request current documentation identifying the relevant product and materials.

What should I verify for a custom color or logo?

Ask whether the evidence covers your selected color and the decoration actually being used, such as embroidery, adhesive application, or heat-transfer printing. Confirm how any changes to materials or production methods affect the test documentation.

Can BSCI or GRS replace chemical test reports?

The supplied information does not describe them as chemical tests. BSCI is identified as a supply-chain auditing system, and GRS is listed as a certification applicable to socks. Request separate, product-specific evidence for restricted substances.

Approval Recommendation

Before authorizing production, compare current test records with the complete sock specification, including materials, colors, and decoration. Then get confirmation that manufacturing will follow that specification. 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 the company credential.
