The supplier has 13 years of total R&D engineer experience, has introduced new products within the past year, and has exported for 24 years, with exports representing 31%–40% of sales. However, it reports no overseas warehouse, showroom, agent, or branch, no available SDK, and no overseas service countries. The provided financial records show zero values for the stated periods, so financial credibility cannot be positively established from...

Supplier typeThe supplier is explicitly classified as a manufacturer. Its stated scope covers R&D, production, and sales of electronic functional ceramic materials, optoelectronic materials, miniature electroacoustic components, sensors, transducers, and related components, indicating direct manufacturing involvement in relevant product categories.
