The stated scope supports classification as an industrial equipment and tooling manufacturer rather than a general trading supplier.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and CE product compliance certification in multiple slices. It also reports conducting regular fire drills during the past year, providing additional operational-safety evidence, although no separate fire-safety certification is stated.
