AI-Powered supplier vetting

SummaryChongqing Deso Lifting Co., Ltd. is identified as a Chinese manufacturer/factory and trading company focused on lifting, rigging, and material-handling products. The supplier reports ISO 9000 and ISO 9001 management-system certifications, 6–10 quality-control staff, five production lines, 6–10 years of R&D engineer experience, and export activity since 2005 with 90% of sales from exports. Its stated markets cover multiple regions, and reported lead times are one month during off-peak periods and 2–3 months during peak periods. The evidence supports established export and production capabilities, but does not adequately verify after-sales service processes, financial credibility, customization capability, or a broad customer track record. Two 2025 trade records identify the same Philippine buyer and products related to round slings and cargo lashing.

Supplier typeThe supplier is described as a Manufacturer/Factory and Limited Company, while its company nature is also listed as a trading company. Its business is focused on lifting equipment, rigging hardware, and material-handling products.

CertificationsThe supplier explicitly reports holding ISO 9000 and ISO 9001 management-system certifications. The provided data does not specify certificate scope, issuing body, or validity dates.

R&D capabilityThe supplier reports 6–10 years of R&D engineer experience and states that it invested in a new Jiangsu factory and facility, updated production lines, and facilities to improve quality and capacity. These facts support some development and improvement capability, although no specific new products, patents, or R&D outputs are provided.

Production capacityThe supplier reports five production lines, 6–10 quality-control staff, a Jiangsu production facility, and product coverage including chain blocks, lever blocks, shackles, wire rope, hoists, slings, and rigging hardware. Reported fulfillment times are one month off-peak and 2–3 months during peak periods, indicating established production and export fulfillment capability.

Client casesThe supplier reports 90% export sales, exports beginning in 2005, and markets across Europe, the Middle East, the Americas, Asia, Oceania, and Africa. Two 2025 trade records show shipments to Iceland Drilling Philippines Corp. in the Philippines involving a 35T endless round sling and cargo-lashing tie-downs, but the evidence covers only one named buyer and two transactions.
