The supplier reports ISO9001, ISO14001, and ISO45001 certifications, nine production lines, 120 years of combined R&D engineer experience, and 11–20 quality-control staff. It serves domestic and overseas markets, with exports representing 21%–30% of sales and reported one-month lead times in both off-peak and peak seasons. Evidence supports manufacturing scale, certification coverage, and technical capability. However, the provided information does not sufficiently establish after-sales service, financial credibility, customization capability, or a broad customer track record.

Supplier typeThe supplier is explicitly classified as a manufacturer, while the associated company information also describes the company nature as a trading company. Its 8,000 m² plant and manufacturing-related business activities support that it operates manufacturing capabilities, although the supplied classifications are not fully consistent.

CertificationsThe supplier reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates, plus other unspecified certifications. This is explicit evidence of multiple quality, environmental, and occupational-health-and-safety certifications.

R&D capabilityThe supplier’s product scope includes magnetic measurement, electrical measurement, gaussmeters, and multifunction calibrators, and it reports 120 years of total R&D engineer experience. These details support technical and product-development capability, although no patent, new-product, or R&D investment data is provided.

Production capacityThe supplier reports an 8,000 m² manufacturing plant, 363 employees, nine production lines, and one-month lead times in both off-peak and peak seasons. These figures provide explicit evidence of established production capacity and stated delivery capability.
