SummaryNanjing Kerun Lubricants Co., Ltd. is a China-based limited company established in 2000, with 124 employees and operations in Jiangsu. It manufactures industrial media, including quenching oils, cleaning agents, rust preventive oils, and related products. Evidence indicates substantial production infrastructure, including a 10,600.8 m² manufacturing site, more than 10 production lines, and stated quenching-oil output of 50,000 tons. The supplier reports 25 years of R&D-engineer experience, 11–20 quality-control staff, exports to East Asia and North America, and serves more than 3,000 industrial customers worldwide. It describes technical R&D, industrial design, service systems, and customized energy-saving and environmental solutions. However, no supplier-management-system certifications are reported, and the slices do not provide sufficient evidence to assess financial credibility or detailed after-sales capabilities.

Supplier typeThe supplier is identified as a Chinese limited company with the legal name Nanjing Kerun Industrial Medium Co., Ltd. and the English name Nanjing Kerun Lubricants Co., Ltd. Its business centers on manufacturing and supplying industrial media, lubricants, quenching oils, cleaning agents, and related solutions.

CertificationsThe supplier-management-system certification field is explicitly reported as “NIL.” The provided evidence therefore shows no declared certification in this category.

R&D capabilityEvidence supports an active technical orientation: the supplier reports R&D engineers with 25 years of total experience, emphasizes technological innovation and new technology, and describes industrial design, R&D, energy-saving, and environmental solutions. These statements indicate innovation capability, although no specific patents, R&D expenditure, or independently verified innovations are provided.

Production capacityThe supplier reports a 10,600.8 m² manufacturing plant, more than 10 production lines, 11–20 quality-control staff, and stated quenching-oil output of 50,000 tons. It also reports one-month order fulfillment in both off-peak and peak seasons, providing explicit evidence of substantial production capacity.

Customization capabilityThe supplier explicitly states that it provides personalized industrial solutions and full solutions tailored to heat treatment, metal processing and molding, surface treatment, cleaning, and rust prevention. This directly supports customization capability for industrial processes, although the scope of product-level customization is not detailed.

Client casesThe supplier states that it serves more than 3,000 industrial customers worldwide, including aerospace, automobile, wind and electricity, ships, household appliances, coal-mining machinery, and steel metallurgy. The slices provide broad sector references but do not identify named customers, project descriptions, or independently verifiable case results.
