SummaryThe supplier demonstrates broad customization, R&D, OEM and ODM capabilities, supported by 48 R&D engineers and documented design-development records. It holds ISO9001:2015, ISO45001:2018, ISO14001 and GRS certifications, and has documented procedures for corrective actions, complaint handling and finished-product inspection. The supplier has exported for 26 years, with exports representing 51%–70% of total sales, and holds self-operated import and export rights. It has valid contracts with associated subcontractors and manufactures sports equipment and toys, but reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches. Customer-case evidence is limited: it has served well-known brands through OEM, participated in the FIBO Exhibition, and reports no cooperation with Fortune 500 companies.
