AI-Powered supplier vetting

SummaryWenzhou Guangda Lock Industry Co., Ltd. is a China-based limited company established in 2010, with 151 employees and a stated manufacturing location in Zhejiang. The supplier reports ISO9001:2015 and ISO14001:2015 certifications, six production lines, a 17,000 m² manufacturing plant, and annual output of 1,000,000 door lock cylinders. It describes precision and digital machining equipment, product testing, international-standard production, customized lock manufacturing, and exports to multiple regions. However, several requested areas lack sufficient direct evidence: after-sales service, financial credibility, and customer case depth. The records also contain inconsistencies, including a “trade company” classification despite manufacturing information and an export start date later than a stated 2021 date in a separate record.

Supplier typeThe supplier is identified as a limited company located in Wenzhou, Zhejiang, China, with 151 employees and a stated factory at 368 Jihong Road. Manufacturing evidence includes a 17,000 m² plant and an industry classification of manufacturing, although one record labels the company nature as a trade company, creating a classification inconsistency.

CertificationsThe supplier explicitly reports ISO9001:2015 and ISO14001:2015 certificates. These provide direct evidence of quality-management and environmental-management certification, although certificate validity dates and issuing bodies are not provided.

R&D capabilityThe supplier reports professional lock technology for designing and developing new products, precision machinery, digital machining equipment, and two years of R&D engineer experience. This supports the existence of product-development capability, but no specific innovations, patents, or development outcomes are documented.

Production capacityThe supplier reports advanced equipment, strict product testing, a 17,000 m² plant, six production lines, 21–30 quality-control staff, and annual output of 1,000,000 door lock cylinders. It also states one-month lead times in both peak and off-peak periods, supporting substantial production capacity, though the annual productivity record is not fully detailed across all products.

Customization capabilityThe supplier explicitly states that it tailors various lock products according to customer demand and develops new products to meet customer requirements. This is direct evidence of customization capability, although no minimum order quantities, customization scope, or examples are provided.
