AI-Powered supplier vetting

SummaryShenzhen Shuntian Hardware Product Co., Ltd. is identified as a Chinese manufacturer established in 2009, operating in Shenzhen, Guangdong, with 24 employees and a 1,505 m² manufacturing plant. Its products include fasteners such as hexagon head bolts, bolts and nuts, as well as hand tools and precision CNC-machined parts. Export sales account for 51%–70% of total sales, indicating meaningful international business exposure. An SGS audit record is shown as valid from August 29, 2025 to August 28, 2026, but the audit type and evaluation result are coded and cannot be interpreted. The supplier’s description explicitly claims ODM and OEM support, while evidence is insufficient for after-sales services, financial credibility, customer cases, environmental compliance, overseas infrastructure, and several operational capabilities.

Supplier typeThe supplier is explicitly classified as a manufacturer and factory in Shenzhen, Guangdong, China. Its stated business covers industrial equipment and components, tools and hardware, including fasteners, hand tools, and CNC-machined parts.

R&D capabilityThe supplier explicitly states that it supports ODM and OEM projects and has an engineering team working from concepts, samples, and blueprints to production. Separate evidence for SDK availability, digitalization, ERP integration, or broader R&D systems is unavailable.

Production capacityThe supplier is a manufacturer with a 1,505 m² plant, 24 employees, and products including bolts, nuts, fasteners, hand tools, and CNC-machined parts. Export sales of 51%–70% and an active-looking SGS audit record support operational experience, but manufacturing capacity, inventory capability, and order fulfillment details are not sufficiently defined.

Customization capabilityThe supplier explicitly claims full customization support through ODM and OEM services, with engineering cooperation based on customer specifications, samples, and blueprints. This directly supports the existence of customization capability, although the scope and technical limits are not stated.
