AI-Powered supplier vetting

SummaryJX PETRO is a China-based factory and limited company founded in 2005, specializing in petroleum drilling and production equipment. The supplier reports API certification, ISO9001, ISO14001, and ISO45001 certifications, six production lines, professional processing and testing equipment, and a manufacturing facility of 11,000–18,000 square meters as reported in different slices. Its product range covers sucker rods, mud pumps, well control and wellhead equipment, downhole tools, handling tools, and rig accessories. The supplier has self-operated import and export rights, but exports reportedly account for only 1%–10% of sales and its primary market is domestic. Evidence supports manufacturing capability, certification, and some R&D activity, including six national patents. No sufficient evidence is provided regarding after-sales service systems, customization capability, or specific customer cases. Financial assessment is limited because financial figures are excluded.

Supplier typeThe supplier is explicitly identified as a factory and as a limited company engaged in manufacturing and supplying petroleum drilling and production equipment. Its stated establishment year is 2005, and its operations are located in Shandong, China.

CertificationsThe supplier states that it holds API certification and ISO9001:2015, ISO14001:2015, and ISO45001:2016 certifications covering quality, environmental, and occupational health and safety management. These certifications provide explicit evidence of formal management-system and product-certification coverage.

R&D capabilityThe supplier reports investment in production technology R&D and talent development, 15 professional and technical personnel, three years of R&D engineer experience, and six national patents. These statements explicitly support the existence of R&D and patent activity, although the scope and commercial impact of the innovations are not detailed.

Production capacityProduction capability is supported by six production lines, 26 large-scale processing machines, more than 20 testing devices, and a reported manufacturing area of 11,000 square meters in one slice and 18,000 square meters in another. The supplier also reports 50 production workers in its company description, while another slice lists 35 total employees, indicating inconsistent workforce data that should be verified.
