SummaryShenzhen Eelink Communication Technology Co., Ltd. is a China-based trading company established in 2004 and focused on GPS tracking products. The supplier reports a Shenzhen manufacturing location, three production lines, annual GPS tracker output of 1,200,000 pieces, and stated order lead times within 15 working days in both off-peak and peak seasons. Its export activity is substantial, with export sales representing 71%–90% of total sales and markets in South America, Europe, and North America. The company describes capabilities in software, hardware, industrial design, Internet platforms, smartphone applications, and customized product development. However, no supplier management-system certifications are reported, and the available information does not provide verifiable customer names or specific customer projects. Some personnel data is inconsistent across slices, so engineering scale should be treated cautiously.

Supplier typeThe supplier is explicitly identified as a trading company and a limited company, engaged in electrical and electronics commerce. It also reports a manufacturing plant and production lines, indicating that its operations include production-related activity despite the stated trading-company classification.

CertificationsThe supplier’s certification of management systems is explicitly listed as NIL. This is direct evidence that no management-system certification is reported in the provided information.

After-Sales capabilityThe supplier explicitly states a commitment to customer satisfaction through quality products and after-sale service. It also describes support through an Internet platform and smartphone application for its GPS trackers, but no detailed service process, response standard, or service coverage is provided.

Financial creditThe supplier has operated since 2004, began exporting in 2004, reports export sales of 71%–90% of total sales, and serves South American, European, and North American markets.
