AI-Powered supplier vetting
SummaryThe supplier demonstrates broad customization, 3D design, ODM, and OEM capabilities, supported by reported new-product development and one national science and technology progress award. Quality, supplier-service assessment, corrective-action, and complaint-handling procedures are documented and followed. The supplier reports inventory capability, export rights, and multiple accepted trade terms, but has no overseas warehouse or showroom and no valid manufacturing-capacity contract with related subcontractors. Production information identifies one production line, 11–20 quality-control staff, and stated valve outputs. Certification evidence includes ISO9001:2015, ISO45001:2018, ISO14001, and CE. Financial credibility cannot be established because the provided financial fields report zero values for the stated periods. Customer references are not explicitly provided.
Supplier typeThe supplier operates manufacturing equipment including machining, welding, line cutting, and painting facilities; it reports one production line, inventory capability, export rights, and service proximity to Qingdao Port. However, it has no valid manufacturing-capacity contract with related subcontractors and no overseas warehouse or showroom.
CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, together with CE and other product-certification capability. These are explicit certification holdings or capabilities in the provided information.
After-Sales capabilityThe company reports technical support and non-traditional after-sales service, while its service-capability procedures, corrective and preventive actions, and customer-complaint handling have written procedures and followed records. This supports a structured after-sales process.
Financial creditThe provided financial records report zero operating revenue, operating cost, gross profit, operating profit, gross margin, and current ratio for the stated periods. These reported figures do not provide positive evidence of financial strength and indicate a material credibility concern.
R&D capabilityThe supplier reports new products within the past year, provides 3D software design and ODM services, supplies OEM services to well-known brands, and holds one national science and technology progress award. It does not have an available SDK, but the broader evidence supports innovation capability.
Production capacityThe supplier identifies machining, welding, line-cutting, and painting equipment, reports 11–20 quality-control staff, one production line, inventory capability, and stated outputs for several valve products. Its lack of a valid manufacturing-capacity contract with related subcontractors limits assurance regarding contracted capacity.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, flexible customization, and minor customization, as well as 3D software design and ODM services. This indicates broad customization coverage across design and manufacturing requirements.
