AI-Powered supplier vetting

SummaryHengshui Milestone Motor Technology Co., Ltd. is identified as a China-based manufacturer/factory in Hebei producing electric motors, including induction, three-phase, special, explosion-proof, high-voltage, and variable-frequency motors. The supplier reports extensive product certifications, including CE, China 3C, CQC, China energy-saving, explosion-proof, KA, and MA certifications, as well as ISO9001, ISO14001, and ISO45001 management-system certifications. Its business description states that it is an early developer and promoter of energy-saving Y-series motors in China and focuses on motor research. A TUV Rheinland audit record is listed as valid from May 19, 2025 to May 18, 2026, but the audit result is coded as “0” without an interpretation. Evidence is insufficient to confirm after-sales services, financial credibility, innovation services such as ODM or SDK support, production scale, customization, or customer cases. Several supplier capability fields are explicitly marked unknown.

Supplier typeThe supplier is identified as Hengshui Milestone Motor Technology Co., Ltd., a China-based manufacturer/factory located in Hebei and operating in the motor manufacturing sector. However, another record describes its company nature as a trading company, creating a classification inconsistency that should be clarified.

CertificationsThe supplier reports CE, China 3C, CQC, China energy-saving, explosion-proof, KA, and MA product certifications, along with ISO9001, ISO14001, and ISO45001 management-system certifications. A TUV Rheinland audit is also recorded for the period from May 19, 2025 to May 18, 2026, although the coded audit result is not explained.

R&D capabilityThe company states that it focuses on motor research and was among the early Chinese enterprises to design, produce, and promote new energy-saving Y-series motors. Nevertheless, ODM, SDK, private-mold, 3D-design, and new-product R&D service statuses are all unknown, so the breadth of its current innovation services cannot be confirmed.

Production capacityThe supplier is listed as a manufacturer/factory offering multiple electric-motor categories, and its company description characterizes it as a large second-tier national enterprise and a top-500 Chinese machinery enterprise. However, manufacturing capacity, inventory capability, order fulfillment details, and production scale are not sufficiently documented; the order fulfillment field contains only an unexplained code.
