AI-Powered supplier vetting

SummaryQingdao Alptec Safety Equipment Co., Ltd. is a China-based limited company in Shandong, established in 2004, with 77 employees and a manufacturing facility of 5,556.14 m². It operates five production lines and reports annual productivity of 5,000 sets for overfill protection and grounding systems. The supplier holds ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates. Its product portfolio focuses on electrical protection, grounding, overfill detection, methane leak detection, and related industrial safety equipment. Evidence indicates established product development experience, including grounding and overfill technologies, but the provided information does not demonstrate after-sales service systems, customization capacity, or broad customer references. Financial information is insufficient for a credibility assessment.

Supplier typeThe supplier is identified as a limited company based in China, with its company type described as combined, its business nature as a trading company, and associated-company industry listed as manufacturing. It also reports a 5,556.14 m² manufacturing plant and commercial involvement in industrial equipment, electrical and electronic products, and related categories, indicating a mixed trading and manufacturing profile.

CertificationsThe supplier explicitly reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates. These certifications provide direct evidence of formal quality, environmental, and occupational health and safety management systems.

R&D capabilityThe supplier reports 22 years of R&D engineer experience and a history of developing grounding alarm, piezoelectric overfill sensor, self-checking socket, upgraded overfill protection systems, and intelligent electrostatic monitoring products. These documented product-development milestones support an established innovation capability.

Production capacityProduction capability is supported by a 5,556.14 m² manufacturing plant, five production lines, reported annual productivity of 5,000 sets for overfill protection and grounding systems, and stated order fulfillment within 15 working days in both peak and off-peak periods. The supplier also has 77 employees, although quality-control staffing is reported as fewer than five.

Client casesOne documented application states that a crash protection product was used at 57 gas stations in 14 provinces within six months. The trade record separately identifies one associated buyer and one transaction, so the evidence supports at least one concrete application case but does not establish a broad or independently verified customer portfolio.
