AI-Powered supplier vetting
SummarySentech (Ningbo) Technology & Development Co., Ltd is identified as a Chinese private limited company and manufacturer/factory, although another record describes the supplier type as a trading company. Its offered products are pumps and ladders, with stated water-pump output of 1,000,000 pieces and 6–10 quality-control staff. The supplier reports BSCI, ISO 14001, and ISO 9001 certifications, plus 6–10 years of total R&D engineer experience. It supports customization from samples, designs, minor customization, and flexible customization, and reports new products during the past year. However, it does not provide ODM services, has no available SDK, and does not provide OEM services for popular brands. Financial records are identified for 2021–2023, but their performance is not disclosed. Audit information identifies TÜV Rheinland and an audit period from September 10, 2024 to September 9, 2025, but the evaluation result is not interpretable from the supplied value. No customer cases or after-sales service...
CertificationsThe supplier reports BSCI, ISO 14001, and ISO 9001 certifications. A TÜV Rheinland audit is also recorded for September 10, 2024 through September 9, 2025, but the supplied audit result value cannot be interpreted as a pass or failure.
R&D capabilityThe supplier reports new products during the past year and has 6–10 years of total R&D engineer experience. Conversely, it has no available SDK and does not provide ODM services; the evidence supports some R&D activity but not a complete technology-development offering.
Production capacityThe supplier reports a factory location, 6–10 quality-control staff, annual water-pump output of 1,000,000 pieces, and an annual production-output range. Its listed products are pumps and ladders, although the conflicting manufacturer/trading-company classifications introduce some uncertainty about the operating model.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, and flexible customization. This is direct evidence of broad customization support, despite the separate absence of ODM services.
