AI-Powered supplier vetting

SummaryShandong Vs Petroleum Technology Co., Ltd is a China-based limited company established in 2019 with 18 employees and a business scope covering electrical equipment sales, maintenance, leasing, construction labor subcontracting, job intermediary services, and import/export. It demonstrates customization, ODM, OEM, 3D design, professional technical service, and offline trade-show capabilities. However, the evidence shows no overseas warehouses, showrooms, agents, branches, or overseas service coverage. Service-control documentation is incomplete: inspection instructions exist without written records, while complaint handling and corrective/preventive-action procedures are absent. R&D evidence is mixed: the supplier offers ODM and OEM services but reported no new product in the previous year, no SDK, and no private molds. Financial records are indicated for 2022–2024, but no financial results are provided, so credibility cannot be fully assessed. No certification information or customer case details are...

Supplier typeThe supplier is identified as Shandong Vs Petroleum Technology Co., Ltd., a Chinese limited company operating in Shandong. Its stated business scope includes electrical equipment sales, maintenance, leasing, construction labor subcontracting, job intermediary services, and import/export, and its company type is recorded as “Combined.”

After-Sales capabilityThe supplier has inspection instructions but no written inspection records, and it has written service-assessment procedures without records. More materially, it reports no written procedures or records for corrective/preventive actions or effective customer-complaint handling, and it has no overseas warehouse, showroom, agent, branch, or overseas service coverage. These findings indicate a documented weakness in after-sales service controls.

R&D capabilityThe supplier provides ODM services, OEM services for popular brands, and 3D software design services, but reports no new product during the previous year, no available SDK, and no private molds. The evidence supports design and technical-service capability but also shows clear limitations in product innovation assets and recent new-product development.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and minor customization, supported by 3D software design services. This is direct evidence of multi-format customization capability.
