AI-Powered supplier vetting

SummaryNingbo Duofan supplies outboard engine parts and operates one production line with stated output of 100,000 sets. It reports ISO 9000, ISO 9001, and OHSAS/OHSMS 18001 certifications, along with 6–10 R&D engineers and 6–10 quality-control staff. Its export sales share is stated at 41%–50%, with export methods including agents, and it supports FOB, CIF, EXW, and CFR terms. The supplier offers sample-based customization but does not provide 3D software design, ODM, SDK, or OEM services for popular brands; it also reports no new products in the past year. Service procedures exist for corrective actions and complaint handling, but written records are absent, and no written procedure or follow-up records are available for effective service assessment. Financial information is incomplete and is not sufficient to assess credibility. No specific customer cases are provided.

CertificationsThe supplier reports holding ISO 9000, ISO 9001, and OHSAS/OHSMS 18001 certifications. These are explicit certifications relevant to management and occupational health and safety systems.

After-Sales capabilityComplaint-handling and corrective/preventive-action procedures reportedly exist, but there are no written records, and no written procedure or follow-up records support effective service-capability assessment. The supplier states its nearest service-related port access is Ningbo Port and Shanghai Port, but overseas service coverage is listed as zero.

R&D capabilityThe supplier claims innovation and strong R&D capability in its company description and reports 6–10 years of total R&D-engineer experience. However, it is not identified as a professional technical supplier, had no new products in the past year, and does not provide 3D software design, ODM, or SDK services.

Production capacityThe supplier offers outboard engine parts, operates one production line, and reports annual output of 100,000 sets. It also states a one-month average lead time in both peak and off-seasons, providing explicit evidence of production activity and stated delivery timing, though capacity breadth appears limited to the available one-line information.

Customization capabilityCustomization from samples is explicitly available, and the company describes customization capability as a strength. However, it does not provide 3D software design, ODM, or SDK services, so customization is supported primarily through sample-based work rather than broader design-development services.
