for Grip Socks.

Yes. We can provide business license, export license, factory registration documents, production capacity overview, key personnel contacts, and a completed vendor questionnaire. If your company uses a standardized onboarding form, send it to us and we'll complete it directly.

We do not source raw materials from the Xinjiang Uyghur Autonomous Region. Our primary yarn and material suppliers are based in Zhejiang province and surrounding regions. We can provide a written UFLPA sourcing declaration, supplier name and location records, and material procurement documentation to support your customs clearance process for US-bound shipments.

For EU buyers, we can provide fiber composition certificates, REACH reference compliance notes, and material safety data sheets for silicone grip components. Third-party lab testing through accredited labs (SGS, Intertek, Bureau Veritas) can be arranged at buyer's cost. We recommend discussing your specific EU regulatory requirements before sampling so we can confirm the correct documentation pathway.

Yes. Each order is assigned an internal batch reference that links to production records, QC inspection data, and material procurement records. In the event of a product issue or post-market audit, we can provide the full production trail for any shipment within our record retention period. Contact us with your order reference and we'll retrieve the relevant documentation.

Yes, we welcome factory audits and cooperate with third-party inspection bodies. We can facilitate on-site audits for qualified long-term buyers. For remote or documentary audits, we can provide factory photos, production floor layout, equipment lists, and completed audit questionnaires. Contact us to arrange the appropriate audit format for your requirements.

Our standard QC process includes incoming material inspection, in-line checks during knitting and grip application, and a final pre-packing inspection covering sizing, appearance, grip adhesion, and packaging. We send pre-shipment photos before dispatch. For larger orders, we can arrange formal AQL-based inspection reports. Third-party PSI through SGS or Bureau Veritas can also be arranged at buyer's request.

We maintain stable material and supplier relationships specifically to ensure consistency across repeat orders. If any material substitution is necessary -- due to supply availability or specification improvement -- we notify the buyer in advance and provide updated material documentation before production begins. No silent substitutions are made on approved styles.

We work with medical distributors on a case-by-case basis. We can provide ASTM F2913 anti-slip reference test data, material safety documentation, production records, and batch traceability support. For FDA 510(k) or EU MDR pathways, we review requirements with your regulatory team and confirm what we can provide. We recommend starting with a documentation consultation call before sampling.
