AI-Powered supplier vetting
SummaryANHUI I-SOURCING INTERNATIONAL CO., LTD. is described as an international product supplier offering liquid level gauges and technology solutions for demanding applications including automotive coatings, cosmetics, seed coatings, and plastics. The supplier reports 13 years of exporting experience, with exports representing 71%–90% of total sales, and has participated in Paintistanbul & Turkcoat. Its stated service strengths include a complaint-handling procedure with records, customization from designs, full customization, ODM services, and lead times within 15 workdays in both peak and off-season. However, the available information shows no overseas warehouse, showroom, agent, or branch; no new products launched in the previous year; one R&D engineer; no 3D design service, SDK, or popular-brand OEM capability; unknown raw-material traceability; and no written corrective and preventive action procedures or records. Certification ownership and customer cases are not evidenced.
After-Sales capabilityThe supplier emphasizes professional customer service and has a clear complaint-handling procedure with follow-up records. It has no overseas warehouse, showroom, agent, or branch, although it has attended an offline trade show and reports lead times within 15 workdays in both peak and off-season; corrective and preventive action procedures are not documented in writing.
R&D capabilityThe supplier has one R&D engineer and offers ODM, design-based customization, and full customization. Innovation evidence is limited because no new products were launched in the previous year, 3D software design is unavailable, and no SDK is available.
Production capacityReported annual productivity is 9,000 tons of pearl pigment, 3,000 tons of glitter powder, and 3,000 tons of glow-in-the-dark powder, with stated lead times within 15 workdays in both peak and off-season. These figures demonstrate stated production capacity for pigment-related products, but the slices do not directly confirm production capacity for the listed liquid level gauge.
Customization capabilityThe supplier explicitly provides customization from designs and full customization, and it offers ODM services. This indicates a stated ability to develop or adapt products based on customer requirements, although no 3D software design service is provided.
