It supplies telecommunications and related metal and plastic products, including fiber-optic closures, cabinets, terminal boxes, ODFs, and patch panels. The supplier reports ISO9001:2015 and ISO14001:2015 certifications, 10 production lines, 30 R&D engineers, and 6–10 quality-control staff. It began exporting in 2007, with exports representing 11%–20% of sales, and exports through agents. Evidence confirms manufacturing, certification, product specialization, and some international trade activity, but does not sufficiently establish after-sales service, financial credibility, customization capability, or a broad customer track record.
