AI-Powered supplier vetting

SummaryGuangdong DuroPower Industries Ltd is a China-based limited-company factory established in 2013, with the provided records showing 25 or 57 employees. It reports broad customization, ODM, recent product development, six R&D engineers, OEM service for well-known brands, written quality and service procedures, and complaint-handling records. However, it has no available SDK, no written corrective/preventive-action procedure for service capability, no overseas warehouse, showroom, agents, branches, or offline trade-show experience. The supplier also reports no valid import/export license, while overseas service coverage is stated as zero. Financial information is represented only by years, without assessable financial metrics. No certification or specific customer case details are provided.

Supplier typeThe supplier is identified as Guangdong DuroPower Industries Ltd, a China-based limited company and factory in Boluo District, Huizhou, Guangdong. It is described as a combined business entity, not an offshore company, and is not part of a larger company group.

After-Sales capabilityThe supplier reports technical support for production and after-sales service, plus a clear customer-complaint procedure with followed records. However, it has no overseas warehouse, showroom, agents, or branches, so the evidence supports internal after-sales procedures but not overseas service infrastructure.

Financial creditThe records list years for financial capacity and a balance-sheet year, but provide no financial indicators or substantive financial assessment. The supplier also has no valid import/export license, which is a documented trade-compliance deficiency relevant to international transactions.

R&D capabilityThe supplier reports new products during the past year, six R&D engineers, responsibilities covering technical support and new product development, and ODM service. Its lack of an available SDK is a stated limitation for SDK-related development capability.

Production capacityThe supplier is identified as a manufacturing factory with 57 employees in one record and 25 in another, maintains written warehouse-control procedures and records, and reports peak-season lead time of one month and off-season lead time within 15 workdays. These records support manufacturing operations, although the inconsistent employee counts and lack of detailed production capacity data limit the assessment.

Customization capabilityThe supplier explicitly reports customization from samples, designs, full customization, flexible customization, and minor customization, as well as ODM availability. This directly demonstrates broad customization coverage.
