AI-Powered supplier vetting
SummaryQILI HOLDING GROUP CO., LTD. is identified as a China-based manufacturer/factory with facilities in Wenzhou, Zhejiang. The supplied information indicates four production lines, 50 quality-control staff, 11–20 years of combined R&D-engineer experience, and reported annual production of 5,000,000 sanitary valve and fitting pieces. It holds ISO 9001 certification and describes multiple specialized workshops, including CNC machining, forming and polishing, hot forging, BPE fittings, and valve production. The company reports exporting to more than 60 countries since 2006, with exports representing 90% of total sales. It states that it provides design, manufacturing, sales, and after-service capabilities, although detailed after-sales procedures are not provided. Custom fitting production is explicitly mentioned. Available trade data records one transaction and one associated buyer, so customer-case evidence is limited.
Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and operates in manufacturing from an address in Wenzhou, Zhejiang, China. However, one record also classifies the company nature as a trading company, creating a conflicting secondary classification.
CertificationsThe supplier is explicitly reported to hold ISO 9001 certification, providing direct evidence of a certified quality-management system.
After-Sales capabilityQILI states that its capabilities cover sales and after-service and that it provides service to customers. The slices do not specify service channels, response times, warranty terms, or repair processes, so the stated capability is positive but not operationally detailed.
R&D capabilityThe supplier has 11–20 years of combined R&D-engineer experience and operates specialized workshops including CNC machining, hot forging, and fittings production. These facts support technical development capability, although no specific patented products or quantified R&D achievements are provided.
Production capacityThe supplier reports four production lines, 50 quality-control staff, and annual output of 5,000,000 sanitary valve and fitting pieces. Its described eight professional workshops and stated pre-delivery quality checks provide direct evidence of substantial manufacturing and quality-control capacity.
Customization capabilityThe company explicitly describes an Anhui mass-production base with CNC machining and the ability to make custom fittings. This directly supports customization capability for fitting-related products.
Client casesThe supplier states that its products are exported to more than 60 countries and lists multiple export markets; one associated buyer, LES INSTRUMENTS PITANCO INC, and one trade transaction are also recorded. These references indicate international customer exposure, but the named customer evidence and transaction history are limited.
