AI-Powered supplier vetting

SummaryShanghai Heyin Silk Co., Ltd. was established in 1994 and supplies scarves, bags, and hats, with business activities covering silk, clothing, handicrafts, and related accessories. The supplier has one production line, a 2,422.0 m² manufacturing plant, 11–20 quality-control staff, two quality assurance and quality-control inspectors in one assessment, and four experienced R&D engineers. It reports customization from samples, OEM service for well-known brands, written procedures for service assessment, corrective actions, complaint handling, and finished-product inspection. Export activity is substantial, with 71%–90% of sales from exports and 31 years of exporting experience. However, no supplier-management-system certification is reported, no SDK is available, and the factory does not continuously reconcile quantities for every batch or production lot. Financial fields identify reporting years but provide no assessable financial results.

Supplier typeThe supplier is a manufacturer and exporter of fashion accessories, with stated production and processing activities covering silk, clothing, and handicrafts, plus sales of scarves, bags, hats, and related products. Its 2,422.0 m² plant, one production line, and export operations support classification as a manufacturing-oriented supplier rather than only a trading intermediary.

CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. Therefore, the provided information does not demonstrate possession of relevant management-system certification and does indicate a stated gap for this field.

After-Sales capabilityThe supplier reports written procedures and followed records for service assessment, corrective and preventive actions, and effective customer complaint handling. These documented mechanisms provide explicit evidence of structured service and complaint-response capability.

Production capacityThe supplier operates a 2,422.0 m² manufacturing plant with one production line and reports annual production output within the stated range. It also has 11–20 quality-control staff, but does not continuously reconcile quantities for every batch or production lot, indicating a documented production-control weakness despite established manufacturing capacity.

Customization capabilityThe supplier explicitly provides OEM services for well-known brands and offers customization from samples. These statements directly demonstrate capability to produce customized products based on customer samples and brand requirements.

Client casesThe supplier states that it has earned recognition and trust from Uniqlo through more than 20 years of cooperation. This is an explicit named customer relationship and provides evidence of experience serving a recognized international brand, although no additional customer-case details are supplied.
