Formal Letter to USA Customer on Tariff Impact

I'm seeking a professional writer to craft a formal letter to our USA customers. The letter should inform them about the implications of current tariffs on our costs, potential price increases and a request for reimbursement. The tone of the letter needs to be strictly formal, without any informal language or colloquialisms. It should be clear, concise, and free of any grammatical errors.

Key Points to Cover:
- Detailed impact of tariffs on our costs
- Possible future price increases
- A formal request for reimbursement

I do not have specific data or statistics to be included in the letter, so it will be up to you to present this information in a compelling way. The ideal candidate for this project will have experience in formal business communication, a strong command of English and an understanding of tariff impacts on pricing.
