AI-Powered supplier vetting

SummaryD&D Hardware Industrial Co., Ltd. is a China-based limited company and factory established in 2018, specializing in door and construction hardware. It operates a 1,368 m² manufacturing plant with six production lines, 45 employees, and 11–20 quality-control staff. The supplier reports ISO 9001:2015 certification and has exported since 2008, with 71%–90% of sales attributed to exports. Its stated capabilities include customization, quality assurance, technical support, and long-term customer relationships, but evidence for after-sales service, specific customer cases, and innovation depth is limited. Financial credibility cannot be conclusively assessed from the available non-financial evidence.

Supplier typeThe supplier is identified as a factory and limited company based in Jiangmen, Guangdong, China. Its stated business scope and product portfolio focus on door hardware, locks, hinges, closers, exit devices, and related construction hardware, indicating a manufacturing-oriented supplier rather than only a trading entity.

CertificationsThe supplier holds an ISO 9001:2015 management-system certificate. This is explicit evidence of a formal quality-management certification, although no additional certifications are provided.

Production capacityThe supplier reports a 1,368 m² manufacturing plant, six production lines, and 11–20 quality-control staff, alongside a broad door-hardware product range. These details provide explicit evidence of an established production setup, although capacity utilization and delivery performance are not stated.

Customization capabilityThe company explicitly claims customization ability and says its qualified team can identify solutions suited to customer needs and technical specifications. This supports a positive assessment, although the slices do not describe customization scope, tooling, minimum order requirements, or completed examples.
