It supports flexible customization, ODM, OEM for popular brands, and reports new products in the past year. Export activity has continued for 11 years, with 51%–70% of sales from exports and self-operated import/export rights. Service strengths include inventory capability, documented complaint and corrective-action procedures, quality assurance, and lead times within 15 working days in both peak and off-season periods. However, the supplier has no overseas warehouse, showroom, agents, branches, or stated overseas-service countries, and has not participated in offline trade shows. Supplier-service assessment lacks written procedures and complete records. Financial credibility cannot be assessed from the non-monetary information provided.
