AI-Powered supplier vetting

SummaryWenzhou Wujing Fastener Co., Ltd. is a China-based trading company established in 2023 with two employees, offering various fasteners and related products. It has explicit ODM, OEM, flexible customization, and self-operated import/export capabilities, with exports representing 90% of total sales. However, the supplier reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, offline trade-show participation, or overseas service coverage. Service-management controls are weak, with no written procedures, approved supplier list, or corrective/preventive-action records. No new products were launched in the past year, and no SDK is available. Financial information is limited to the presence of records for specified years, without performance values. An audit by BV is recorded, but the evaluation result is stated as 0 and no certification holding is identified.

After-Sales capabilityThe supplier has stated lead times of within 15 workdays in the off-season and one month during peak season, and accepts EXW, FOB, and CIF terms. However, it reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, offline trade-show participation, or overseas service coverage; service-management procedures and corrective/preventive-action records are also absent.

R&D capabilityThe supplier reports no new products launched during the past year and no available SDK, which limits evidence of recent product innovation and software-development capability. It does provide ODM services, but this alone does not establish a broader innovation record.

Production capacityThe supplier reports no in-stock capability, while its service-capability controls lack written assessment procedures, approved supplier lists, and corrective/preventive-action records. It is identified as a trading company with two employees and no cooperative suppliers recorded; although stated lead times are available, the evidence does not demonstrate robust in-house production capacity.

Customization capabilityThe supplier explicitly states that it provides flexible customization, ODM services, and OEM services for well-known brands. These statements provide direct evidence of customization and contract-manufacturing support, although no technical scope, tooling capability, or project examples are provided.

Product Q&A

Q:What is your delivery time?

It depends. If we have bulk goods in stock, we can ship goods within 3 days after the QC process. If we don't have stock, normally it takes 7-15 days for OEM samples and 20-30 days for bulk goods. If it refers to opening the new mold, it takes an extra 7-15 days to make the mold.

Q:What are your payment terms?

Normally, we make a 30% deposit after PI confirmation and a 70% balance before shipment.

Q:How do you guarantee good quality?

A pre-bulk sample check can solve this problem to the largest extent. We will arrange production according to the pre-bulk sample quality standard after your confirmation of the samples.

Q:Do you offer free samples?

Yes, samples are free, but the shipping cost is covered by the customer.

Q:Can you customize non-standard products?

Yes, we customize all kinds of non-standard products according to drawings or physical samples.
