Dear Customer, Perhaps you have noticed that the recent “dual control of energy consumption” policy of the Chinese government. China will toughen punishments for regions that fail to meet targets aimed at controlling energy use, the state planning agency said in new policy guidelines published on Thursday (16th Sep 2021). China has been cracking down on high-energy consuming projects after 20 of its 30 provinces and regions failed to meet energy consumption targets in the first half of the year. In addition, the China Ministry of Ecology and Environment has issued the draft of “2021-2022 Autumn and Winter Action Plan for Air Pollution Management” in September. This autumn and winter (from October 1, 2021 to March 31, 2022), the production capacity in some industries may be further restricted. This step would have a certain impact on the production capacity of some manufacturing companies, and the delivery of orders in some industries has to be delayed. To mitigate the impact of these restrictions, we recommend that you place an order as soon as possible. We will arrange production in advance to ensure that your order can be delivered on time.
