关于汇率变动

Dear valued customer,
We appreciate your business and thank you for choosing us as your supplier. However, we'd like to inform you that due to fluctuating exchange rates, the current rate is much different from what we quoted earlier this year. This has caused a loss in our factory's profit margins if we follow the current exchange rate to fulfill your order.
We understand that this is not the news you were hoping to hear and we sincerely apologize for any inconvenience this may cause. In order to continue to provide you with high-quality products and services, we kindly request your cooperation in adjusting the price of your order to compensate for the difference caused by the exchange rate fluctuation. We hope you can understand our situation and we appreciate your support and understanding.
Thank you for your attention and please let us know if you have any questions or concerns.
Best regards, [Your company name]
