The State Administration for Market Regulation has issued a notice announcing that the TSG 07-2019 "Special Equipment Production and Filling Unit License Rules" will come into effect on June 1, 2019, achieving a significant change in the work of special equipment production licenses. Starting from June 1, no new manufacturing and installation licenses will be issued, and the new production license review requirements will be stricter than in the past.

After the modification of the new rules, the confidence of elevator companies has been enhanced, and a healthier development environment can be achieved. It is reported that the first batch of elevator brands in China to obtain this qualification include Singlin Elevator and Meilun Elevator. A1 qualification means that in the future, elevator manufacturers will no longer be limited by speed and load capacity when producing elevators.
