Dear Valued Customers:

Several market factors, including rapidly rising copper/aluminum/ABS/PA66 and recent power shortage problem in China, have increased our costs significantly. This is affecting our entire industry greatly.

Many of our customers are probably seeing rising material prices already. We have tried to maintain our current pricing as long as possible, but we cannot continue to do so.

In order to cover rapidly rising cost, we will be increasing our prices on Siboly Brand Air Coolers by 10 - 15% effective November 10, 2021.

To assist in planning and communicating with your customers, you may find this letter at the following link on our website:

Siboly will continue to support our valued customers. This pricing action will allow us to continue to provide the high level of service and quality you have to come to expect from Siboly. If you have any questions, please contact your sales manager at Siboly.

Sincerely,

Xiaoliang Chen

Fujian Siboly Envirotech Co., Ltd
