AI-Powered supplier vetting

SummaryTaizhou Tonhe Flow Control Co., Ltd. is a China-based limited company established in 2009, operating in electric control valves, motorized valves, and electric actuators. The supplier reports mechanized production lines, more than 10 production lines, an annual electric actuator valve output of 150,000 pieces, ISO 9001:2015 certification, and exports to East Asia, Europe, and North America. Its stated lead time is within 15 working days in both peak and off-peak periods. Evidence supports established manufacturing, quality-management, export, and product-development capabilities. However, the provided information does not sufficiently verify after-sales performance, financial credibility, customization services, or specific customer cases.

Supplier typeThe supplier is identified as a China-based limited company with a combined business-entity type, while its associated-company classification describes it as a trading company. Its own description presents it as a professional manufacturer and exporter of electric control valves, indicating a mixed manufacturing and trading profile.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. This is explicit evidence of a certified quality-management system, although no certification scope, issuer, or validity period is provided.

R&D capabilityThe supplier reports intelligent product design, ongoing product improvement, new-product R&D, cooperation with Zhejiang University Research Institute and Taiwan Jianfeng MBA Group, and multiple utility-model patents. It also reports four years of R&D engineer experience, supporting an active but not fully quantified innovation capability.

Production capacityEvidence includes mechanized production lines, more than 10 operating production lines, annual electric actuator valve productivity of 150,000 pieces, and stated order fulfillment within 15 working days in both peak and off-peak periods. These figures support established production capacity and delivery readiness, although the reported overall annual output category is not independently reconciled with the piece-volume figure.
