Thanks for your support to ANTAIOS in the past. Due to the rise of raw materials and the continuous impact of the epidemic on production activities, we have decided to adjust the EXW price of our engine products in RMB as follows after careful research(The quotation of USD, EURO and other foreign currencies is based on the RMB price and calculated in real time according to the exchange rate on the quoted day):

1. The price of the whole series of engine products will be increased by 5%;

2. Other business policies keep same as before.

The above adjustments will be valid from February 1, 2022.

It’s deeply regret for this price adjustment. We will continue to provide our customers with high quality products and services.
