AI-Powered supplier vetting

SummaryTianyuan is identified as a Shanghai-based trading company whose business scope includes filtering equipment, filter cloth, hardware and mechanical equipment, building materials, and import/export activities. It has exported since 2006 and holds self-operated import/export rights, with exports representing 31%–40% of total sales. The supplier reports more than 10 production lines, 11–20 quality-control staff, in-stock capability, and lead times within 15 working days in both peak and off-season periods. Its R&D offering includes new-product development, ODM, and multiple customization modes, although the stated R&D engineer experience is limited to 1 year and no SDK is available. ISO certification is reported, but no specific certificate details are provided. Financial records are indicated for 2023–2025, but the slices do not provide enough information to assess financial strength. No customer cases or named-brand OEM experience are documented.

CertificationsThe company description states that it holds an ISO certificate and other honors. However, no ISO standard, certificate number, issuing body, or validity information is provided, so the certification claim cannot be assessed in detail.

R&D capabilityThe supplier reports annual R&D investment, new-product development during the past year, and ODM capability. Conversely, the stated total R&D engineer experience is only 1 year and no SDK is available, so the evidence supports the existence of R&D activity but not strong technical depth.

Production capacityThe supplier reports operating above 10 production lines, employing 11–20 quality-control staff, maintaining inventory capability, and achieving lead times within 15 working days in both peak and off-season. Nevertheless, it is classified as a trading company and its manufacturing-capacity contract status is unknown, so the extent of directly controlled production capacity is not fully established.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, providing direct evidence of broad customization support.
