Supplier typeThe supplier is a Chinese limited company and a combined business entity focused on technology and service, engineering contracting, material testing, agricultural machinery, bearings, rolling elements, and OEM-related products. Its stated product and service scope indicates a manufacturer and engineering/service provider rather than a narrowly specialized trading company.

CertificationsThe supplier explicitly reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates, along with other unspecified certifications. These cover quality, environmental, and occupational health and safety management systems.
