AI-Powered supplier vetting
SummaryZhongshan Doublemax Electrical Appliances Co., Ltd. is a China-based limited company established in 2017, operating from Guangdong with 44 employees and a 6,000 m² manufacturing plant. It produces a broad range of kitchen and water-heating appliances, operates more than 10 production lines, and exports to multiple regions. The supplier reports ISO9001:2008 quality-system certification, TUV Rheinland site-audit passage, and various product certifications, while its management-system certification field is recorded as NIL. Innovation evidence includes a stated 36-engineer R&D team, experienced personnel, and appearance-design patents, although another record lists six total R&D engineers. Export activity reportedly began in 2009, but the available transaction evidence includes only one buyer-linked transaction in 2025. After-sales service, financial credibility, and customization capability cannot be conclusively assessed from the provided information.
Supplier typeThe supplier is identified as a combined business and limited company based in China, specializing in electrical and consumer electronics. Its stated products include range hoods, gas and electric water heaters, stoves, ovens, induction cookers, and related parts.
CertificationsThe supplier reports passing TUV Rheinland site certification audits and holding ISO9001:2008 quality-system certification; it also states that more than 50% of products passed CE, CB, COC, SASO, EMC, and KUCAS certification. However, supplier management-system certification is separately recorded as NIL, so the evidence supports product and quality certifications but not comprehensive management certification.
R&D capabilityThe supplier states that its R&D team includes 36 engineers with more than 10 years of high-end kitchen-appliance experience and that it holds multiple appearance-design patents. A separate record lists six total R&D engineers, creating an internal inconsistency, but the slices still provide explicit evidence of dedicated R&D and patent activity.
Production capacityThe supplier reports a 6,000 m² manufacturing plant, 44 employees, more than 10 production lines, and a broad appliance portfolio. Its stated manufacturing scope and infrastructure indicate established production capability, although actual capacity by product, utilization, and delivery performance are not provided.
