AI-Powered supplier vetting

SummaryShenzhen Shiyusheng Technology Co., Ltd. is described as a Bluetooth headset and related-products manufacturer combining R&D, production, sales, and OEM/ODM/OBM services. It reports broad customization capabilities, recent new-product activity, ODM availability, and OEM service for well-known brands. However, its quality and service-management controls are weakly documented: it has one quality inspector, finished products are checked by packing staff, and no written procedures are reported for quality assurance, complaints, corrective actions, or supplier approval. The supplier states more than 10 years of headphone-production experience, but also reports only one year of exporting goods, fewer than five R&D engineers and quality-control staff, no SDK, and no overseas service infrastructure. Financial information is excluded, and the available financial records are insufficient for a credibility assessment.

Supplier typeThe supplier is presented as a factory and industry-trade enterprise focused on Bluetooth headsets and related electronics, with R&D, production, sales, and OEM/ODM/OBM functions. Its listed products include speakers, earphones, phone cases, chargers, power banks, memory cards, and phone cables, while its stated export markets span multiple global regions.

CertificationsThe supplier lists BSCI, ISO 9000, ISO 9001, ISO 14001, ISO 14000, ISO 20000, ISO 14064, QC 080000, TS 16949, OHSAS/OHSMS 18001, GMP, and HSE as supplier-management-system certifications. The slice does not provide certificate numbers, validity dates, scopes, or verification details, so the assessment is based only on the stated holdings.

After-Sales capabilityThe supplier reports no written procedures or records for service assessment, corrective and preventive actions, or effective customer-complaint handling, and states that it has no overseas warehouse, showroom, agents, branches, or offline trade-show experience. It does offer multiple quotation and payment terms and reports lead times within 15 working days in both peak and off-season, but the documented after-sales controls are deficient.

R&D capabilityThe supplier states that it has an R&D team, has introduced new products within the past year, provides ODM services, and offers OEM/ODM/OBM solutions. However, it reports no available SDK and fewer than five R&D engineers, so the evidence supports product-development capability but not strong software-development or large-scale R&D capacity.

Production capacityThe supplier describes an established headphone production line, more than 10 years of headphone-production experience, and broad export-market coverage. It reports lead times within 15 working days and an annual production output range, while fewer than five quality-control staff and only one stated quality inspector indicate limited documented quality-control staffing.

Customization capabilityBoth customization records list customization from samples, designs, full customization, minor customization, and flexible customization. The company description also identifies OEM/ODM/OBM as part of its operating model, providing explicit evidence of broad customization capability.
