AI-Powered supplier vetting
SummaryLongyear Electric Industrial Co. Ltd. is a China-based limited company in Zhejiang, established in 2012, with 20 employees and a stated manufacturing/trading profile. It offers Voltage Protectors and Battery Testers, reports annual Voltage Protector productivity of 400,000 pieces, and derives 90% of total sales from exports. Company descriptions state that it provides OEM/ODM services, conducts product research and development, and uses an ISO9001 quality-control system. However, most operational capabilities—including contract status, inventory, overseas services, ODM/OEM verification, traceability, environmental documentation, and digital systems—are marked unknown. A BV audit is recorded with an evaluation result of 0, but the slices do not define the scoring scale or explain the result. No customer cases are provided. The assessment therefore identifies export experience, stated production volume, and declared technical/OEM/ODM capabilities, while leaving several supplier qualification areas unverified.
Supplier typeThe supplier is identified as a China-based limited company in Zhejiang, with company information also describing it as a trading company. Its stated activities include research and development, production, sales, and export, while 90% of total sales are reported as exports.
R&D capabilityCompany descriptions characterize Longyear as technology-driven, with professional technical teams and ongoing development of innovative products; another description states that it conducts research and development of intelligent power controller products. Specific new-product counts, private-mold capability, 3D design, SDK availability, and product-information R&D are unknown.
Production capacityThe supplier lists Voltage Protector and Battery Tester as primary products, reports annual Voltage Protector productivity of 400,000 pieces, and has 20 employees. These records provide explicit evidence of production activity and stated capacity, although manufacturing-capacity contract status and raw-material traceability remain unknown.
Customization capabilityThe company explicitly states that it provides OEM and ODM services. Nevertheless, the structured ODM/OEM capability fields and related private-mold and 3D-design capabilities are marked unknown, so the scope and verification of customization services are not established.
