AI-Powered supplier vetting
SummaryThe supplier demonstrates documented service-capability procedures, corrective-action controls, and defined complaint-handling processes. It holds ISO9001:2015 and ISO14001:2015 certifications, reports a structured R&D team, recent new-product development, 3D design, ODM, OEM, and broad customization services. Production information includes three production lines, stated monthly filter capacities, and approximately 25-day delivery after order confirmation. Financial credibility cannot be fully assessed because the slices identify financial records by year but provide no non-financial performance evidence; monetary figures are omitted. Customer-case evidence is limited to statements of OEM service for known brands and listed export markets.
Supplier typeThe supplier presents itself as a manufacturer with in-house R&D, production capacity, import/export rights, ODM services, and OEM services for known brands. Its stated product capacities cover humidifier, HEPA, and other air filters, indicating an industrial filter manufacturer rather than a pure trading or service company.
CertificationsThe supplier explicitly reports ISO9001:2015 quality-management and ISO14001:2015 environmental-management certificates. It also states that the certifications were obtained in 2005, while the current certificate entries are identified as ISO9001:2015 and ISO14001:2015.
After-Sales capabilityAfter-sales support is included in the R&D engineer responsibilities, and the supplier reports a clear customer-complaint procedure with followed records, quality assurance, traceability, and corrective/preventive-action procedures with records. These are explicit process controls supporting after-sales handling, although overseas service coverage is listed as zero countries.
R&D capabilityThe supplier reports more than 50 patent certificates, a 12-person R&D team including two doctors and one graduate student, new-product development during the past year, 3D software design, and available R&D audit documentation covering design inputs, outputs, reviews, verification, and validation. It lacks an available SDK, but the broader evidence supports established innovation capability.
Production capacityThe supplier reports three production lines and monthly capacities of 300,000 humidifier filters, 100,000 HEPA filters, and 150,000 other air filters. It also states delivery of about 25 days after order confirmation, peak-season lead time of one month, and off-season lead time within 15 working days, providing explicit evidence of production scale and defined delivery performance.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, 3D software design, ODM, and OEM services. This combination indicates broad design-to-production customization capability.
