AI-Powered supplier vetting

SummaryDiligence & Fine Machinery (Qingdao) Co., Ltd. is identified as a China-based limited trading company established in 2025, focused on transmission components and broader industrial machinery. The supplier reports more than 10 production lines, 6–10 quality-control staff, annual capacity of up to 5 million pieces, and export sales representing 71%–90% of total sales. Its stated product range includes gears, pulleys, belts, couplings, shafts, flanges, locking devices, and non-standard parts. The supplier claims design capability through experienced engineers, advanced equipment, and the ability to provide non-standard products, but the evidence does not establish certifications, documented customer cases, or proven after-sales performance. The records also contain capacity inconsistencies and state zero total staff experience, limiting confidence in the scale and maturity assessment.

Supplier typeThe supplier is explicitly classified as a Trading Company and a limited company based in Qingdao, China. Its business description further states that it integrates manufacturing and sales of transmission components, with products mainly for export.

R&D capabilityThe supplier claims that transmission parts are developed and designed by capable and experienced engineers and that advanced equipment has been invested in. It also lists high-precision products and various non-standard parts, providing some evidence of design and engineering capability, but no patents, R&D data, or verified innovation results are stated.

Production capacityThe supplier reports more than 10 production lines, 6–10 quality-control staff, annual capacity of up to 5 million pieces, and stated outputs for shafts, couplings, belts, pulleys, and gears; export sales are reported at 71%–90%. However, the 112.2 m² plant area, zero reported total staff experience, and inconsistencies in the capacity entries reduce confidence in the completeness and reliability of the production profile.

Customization capabilityThe product description explicitly includes various non-standard parts and castings, while the supplier states that its engineers develop and design a full range of transmission parts. This directly supports the ability to handle at least some customized or non-standard component requirements.
