涨价通知（范文）用英语怎么说

Dear Sir,

Due to the raw material cost of XX company increasing, we have to increase the price of below models for 5% base on the original price from now on：

Model ABCDE
Model EFGHI

This is a tough decision and we understand this will bring you inconvenience, but 5% is our best effort to keep balance between our customers and covering our cost.

We greatly regret any inconvenience it may cause, and hope we can receive strong support from your side.

Thank you very much. I'm available for any questions you may have.

Best regards
XXXXXX

以上是比较谦虚的版本，如e69da5e887aae799bee5baa6363果厂方没有这么弱势，可以写的强硬些。
Dear **

The latest prices will be effected on 1st,Sep.
