AI-Powered supplier vetting
SummaryYongdun demonstrates established manufacturing, customization, export, and quality-management capabilities. It reports annual production of 50,000 chipping hammers and 100,000 concrete breakers, supported by CNC and machining equipment. The supplier offers OEM and ODM services, broad customization options, and documented finished-product inspection procedures. It holds ISO 9001-related certification and reports CE, coal explosion-proof, and coal safety certifications. Export experience spans 12 years, with 41%–50% of sales from exports. However, it reports no new products in the past year, no SDK availability, and no overseas warehouses, showrooms, agents, or branches. Financial information is represented only by years, so financial strength cannot be assessed. Customer evidence includes industry reputation, dealers, OEM service for well-known brands, and repeat-buyer preference of 50%–80%, but no Fortune 500 cooperation.
Supplier typeThe supplier is presented as a manufacturing-oriented OEM/ODM supplier producing chipping hammers and concrete breakers, with CNC and machining equipment, 12 years of export experience, and participation in an international hardware trade fair. It also provides customized manufacturing and reports OEM service for well-known brands.
CertificationsThe supplier reports complete ISO 9001 quality-management certification, ISO9001:2015 certification, CE certification, national coal explosion-proof inspection certification, and national coal safety mark-related certification. The evidence explicitly supports multiple management and product-related certifications, although some certification entries are labeled only as “Others.”
Production capacityReported annual productivity is 50,000 chipping hammers and 100,000 concrete breakers. The supplier also lists CNC grinding, drilling, machining, machining-center, and cutting equipment, with one-month average lead times in both peak and off-season, providing explicit evidence of established production capacity.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These options are reported both as design-service capabilities and as R&D-provided design services, indicating broad product customization support.
Client casesThe supplier reports that its products are popular domestically and abroad, have industry and dealer praise, and that it provides OEM services for well-known brands. It reports no cooperation with Fortune 500 companies, while repeat buyers account for 50%–80% of preference, so customer-market evidence is positive but does not include named or independently verifiable major cases.
