AI-Powered supplier vetting
SummaryZhejiang Jialong Mechanical Equipment Co., Ltd. is a China-based limited company established in 2001, with approximately 169–173 employees and five production lines. It offers fuel tanker equipment and reports annual output for Bottom Valves, API Adaptor Valves, and Manhole Covers. The supplier provides multiple customization options and has 11–20 quality-control staff, but reports no new products in the past year, no ODM service, and no available SDK. Quality assurance is stated to exist, and an ISO9001:2015 certificate is reported; however, service-related procedures, approved-supplier records, complaint-handling procedures, and corrective/preventive-action records are absent. The supplier has no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Financial records are referenced for 2022–2024, but the slices do not provide sufficient non-financial evidence to assess financial credibility. No customer cases are provided.
Supplier typeThe supplier is identified as Zhejiang Jialong Mechanical Equipment Co., Ltd., a China-based limited company operating from Zhejiang. It is described as a combined company, is not part of a larger company group, and supplies fuel tanker equipment.
CertificationsThe supplier reports an ISO9001:2015 certificate and states that quality assurance exists in its quality-control processes. However, it also lacks a factory environmental impact assessment report, so the evidence supports quality certification but not broader certification coverage.
After-Sales capabilityAfter-sales and service-management evidence is weak: there are no written procedures or records for complaint handling, corrective and preventive actions, or service assessment. The supplier also has no overseas warehouse, showroom, agents, branches, or offline trade-show experience, although it reports a one-month average lead time and accepts several trade and payment terms.
R&D capabilityThe supplier reports no new products during the past year, no ODM service, and no available SDK. These statements indicate limited demonstrated innovation and development support in the supplied evidence.
Production capacityThe supplier operates five production lines, employs approximately 169–173 people, and reports 11–20 quality-control staff. It also lists annual production of 20,000 Bottom Valve sets, 10,000 API Adaptor Valve sets, and 10,000 Manhole Covers, providing explicit evidence of established manufacturing capacity.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This broad range supports a positive assessment of its stated customization capability.
