AI-Powered supplier vetting

SummaryHangzhou Duokai Technology Co., Ltd. is identified as a China-based manufacturer/factory producing dehumidifiers, humidifiers, and related equipment. The supplier reports ISO 9001 certification, product certifications including CE, RoHS, and ETL, six production lines, 11–20 quality-control staff, and stated annual output of 500,000 dehumidifiers and 3,000,000 humidifiers. It reports 6–10 years of R&D engineer experience, more than 10 professional technicians, OEM/ODM services, and export activity beginning in 2013 with 41%–50% of sales from exports. Evidence is insufficient to assess after-sales service, financial credibility, or customer cases. Some company records conflict on whether it is a manufacturer/factory or trading company, so the supplier type assessment is based on the explicit manufacturer and production evidence while noting the inconsistency.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory in slice 1, and its descriptions cite factory production capacity, production capability, and manufacturing of dehumidifiers and humidifiers. However, slice 3 separately classifies the company nature as a trading company, creating a record inconsistency; the production evidence supports manufacturer status but does not eliminate the conflicting classification.

CertificationsThe supplier states that its products hold CE, RoHS, and ETL certifications and that the company has passed TUV and ISO 9001:2015 certification. Slice 8 independently lists ISO 9001 as its management-system certification, providing explicit evidence of certification holdings.

R&D capabilityThe supplier reports more than 10 professional technicians, including humidity-control experts and air-conditioning engineers, and 6–10 years of R&D engineer experience. This directly supports an established technical and R&D capability, although no specific patents, new-product launches, or quantified R&D investment are provided.

Production capacityThe supplier reports six production lines, 11–20 quality-control staff, annual output of 500,000 dehumidifiers and 3,000,000 humidifiers, and a stated annual production capacity of 500,000 units in another description. The output figures demonstrate substantial stated capacity, although the two descriptions are not fully consistent and the humidifier productivity field in slice 2 is incomplete.

Customization capabilityThe supplier explicitly states that it provides OEM and ODM services. This is direct evidence of customization capability, although the slices do not specify supported customization scope, minimum order quantities, tooling, or development timelines.
