Dear [客户名称]

Thank you for your

We would like to clarify that the FOB price we provided is in fact very competitive and we believe it reflects the quality of our products. However, we understand that CIF prices include additional costs such as freight and insurance, which may affect the overall price.

We would be happy to work with you to find a solution that meets your budget requirements. Please let us know if there is anything else we can do to assist you in this matter.

Thank you for your understanding and we look forward to the possibility of working with you.

Best regards。
