AI-Powered supplier vetting
SummaryNingbo Strong Bolt Trade Co., Ltd. is a China-based trading company established in 2014 with 16 employees. It reports strong customization and ODM capabilities, new product activity within the past year, and extensive export activity, with 90% of sales from exports and 10 years of export experience. Its stated product output covers several fastener categories, while quality control staffing is reported at 11–20 personnel. However, service-management procedures lack documented records, and the company reports no overseas warehouses, showrooms, agents or branches, or offline trade-show participation. Financial information is identified for 2021–2023, but the provided slices do not give sufficient evidence to assess financial strength. No certification information, customer cases, or SDK availability is provided.
Supplier typeThe supplier is identified as a trading company, specifically Ningbo Strong Bolt Trade Co., Ltd., established in 2014 in Ningbo, Zhejiang, China, with 16 employees and limited-company status. This clearly establishes its business type but does not indicate that it operates as a manufacturing entity.
After-Sales capabilityThe supplier has written procedures for service assessment, supplier approval, corrective and preventive actions, and complaint handling, but no written records are reported for these processes. It also lacks overseas warehouses, showrooms, agents or branches, and reports zero countries with overseas services, limiting evidence of established international after-sales infrastructure.
R&D capabilityThe supplier reports that it introduced new products during the past year and provides ODM services. However, it reports no available SDK, so its innovation evidence supports product development and design services but not software-development integration.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization and design-related service capability.
