AI-Powered supplier vetting

SummaryThe supplier demonstrates OEM and ODM capability, customization services, and certifications including ISO9001, ISO14001, and ISO45001. Production evidence indicates one production line, approximately 3,000 tons of bag-filter output, and one quality-control inspector. Service and quality procedures exist, but several have no written records. Overseas support is limited: no overseas warehouse, showroom, agents, branches, or reported overseas service countries. Financial records are identified for 2021–2023, but the provided slices do not establish financial strength. Innovation evidence is limited because no new product was reported in the past year and no SDK is available. No specific customer cases are provided.

Supplier typeThe supplier provides OEM services for well-known brands and ODM services, operates manufacturing equipment and a production line, and offers production, installation, maintenance, and customization-related services. These details support classification as a manufacturer with OEM/ODM capabilities.

CertificationsThe supplier reports ISO9001:2015, ISO14001 or ISO14001:2015, and ISO45001:2018 certifications across its management and sustainability information. This is explicit certification evidence, although the slices do not provide certificate scope or validity dates.

Production capacityThe supplier reports one production line, approximately 3,000 tons of annual bag-filter output, manufacturing equipment including bending, lathe, radial drilling, and shearing machines, and a factory manufacturing team. Quality-control staffing is limited to one inspector or fewer than five staff, while finished-product inspection has instructions but no written records.

Customization capabilityThe supplier explicitly offers customization from customer designs, full customization, minor customization, and flexible customization, alongside ODM services. This provides direct evidence of broad customization capability.
