AI-Powered supplier vetting

SummaryYuyao Meigesi Fastener Co., Ltd. is a China-based limited trading company established in 2010 and operating from Zhejiang. It supplies standard fasteners and related hardware, including screws, bolts, nuts, anchors, washers, rigging, and architectural and furniture hardware. The supplier reports more than 10 production lines, fewer than five quality-control staff, a 250 m² manufacturing plant, and approximately one month off-peak lead time versus two to three months during peak season. It exports to a broad range of regions and reports that 90% of sales are from exports. Products can be produced to DIN, ISO, ANSI, BS, JIS, or customer requirements, with stated grades from 4.8 to 12.9; CE and ISO certifications are also claimed. Evidence is insufficient to assess after-sales service, financial credibility, innovation, or customer cases. The supplier combines own production with sourcing from partner companies, so actual manufacturing scope should be verified for specific products.

Supplier typeThe supplier is identified as both a trading company and a limited company, with operations in Zhejiang, China. Its stated business covers tools and hardware, while its own description identifies it as a professional enterprise producing standard fasteners; it also supplies products sourced from partner companies.

CertificationsThe supplier states that it has achieved CE and ISO certifications. The slices do not identify the specific ISO standard, certificate numbers, scope, or validity, but they provide explicit evidence of claimed certification holding.

Production capacityThe supplier reports more than 10 production lines, a 250 m² manufacturing plant, and production of standard fasteners including screws, bolts, nuts, anchors, washers, and rigging products. It also states that products can follow DIN, ISO, ANSI, BS, or JIS standards, although fewer than five quality-control staff and the use of partner companies for some products should be considered when validating capacity and control.

Customization capabilityThe supplier explicitly states that production can follow customer requirements in addition to DIN, ISO, ANSI, BS, and JIS standards. The slices do not specify minimum order quantities, engineering support, tooling capability, or customization limits, but they do support a positive assessment of stated customization capability.
