It exports primarily to Southeast Asia, with recorded transactions involving one Mexican buyer for inserts and taps in 2025. The company states a commitment to stable quality, service, and continuous innovation, but no certifications are provided. Its stated lead times are 4–6 months off-season and 2–3 months peak season, and its export sales share is 11%–20%. Evidence is insufficient to establish financial strength, formal after-sales processes, or broad customer coverage.
Supplier typeThe supplier is explicitly classified as both a trading company and a manufacturer/factory. It is a limited company based in Fujian, China, with a stated factory location in Shanghai in another record, indicating manufacturing-related operations but also a location discrepancy requiring verification.
