AI-Powered supplier vetting
SummaryShenzhen Yifan Technology Co., Ltd. is a China-based limited company established in 2016 with 60 employees, offering gas detectors and temperature testers. It demonstrates documented corrective-action, complaint-handling, supplier-assessment, and service-capability procedures, plus quality assurance, raw-material traceability, and 100% finished-product inspection. The supplier supports customization, ODM, OEM for popular brands, and has introduced new products within the past year and provides an SDK. However, it does not provide 3D software design, overseas warehouses, overseas showrooms, overseas agents or branches, or services in any stated overseas country. Manufacturing capacity has a significant documentation gap because no valid contract exists between the factory and its related subcontractor. Evidence is insufficient to confirm certifications, financial credibility, or customer cases.
Supplier typeThe supplier is identified as Shenzhen Yifan Technology Co., Ltd., a China-based limited company with a combined business type and 60 employees. It is not identified as part of a larger company group or an offshore company.
After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions, customer complaints, supplier-service assessment, and offers inventory capability. Its service reach is limited by the absence of overseas warehouses, overseas showrooms, overseas agents or branches, and stated overseas service countries.
R&D capabilityThe supplier reported new products within the past year, provides ODM services, supports OEM for popular brands, and has an available SDK. These points provide explicit evidence of product-development and technical-support capability, although 3D software design is not offered.
Production capacityProduction-related evidence includes 100% finished-product inspection, two quality inspectors, raw-material traceability, inventory capability, and stated peak- and off-season lead times within 15 workdays. However, the factory and related subcontractor do not have a valid manufacturing-capacity contract, which is a documented production-governance deficiency.
Customization capabilityThe supplier explicitly supports customization from samples and designs, full, minor, and flexible customization, and also provides ODM and OEM services. This directly demonstrates broad customization coverage.
