Hi @Seller_h3v0nXESGeHq0

The brand authorization letter is a critical document that needs to meet specific requirements in order to be accepted by Amazon.

Based on the information provided in the webpages, a brand authorization letter needs to contain several key elements:

Identification of the brand owner - The legal name of the brand owner, their contact information, and their Amazon seller account details should be clearly stated.

Identification of the authorized seller - The legal name of the third-party seller, their contact information, and their Amazon seller account details should be provided.

Authorized products - A specific list of the products that the seller is authorized to sell, including product codes and descriptions.

Terms and conditions - The duration of the authorization and the intellectual property usage guidelines should be specified.

Signatures - The letter should be signed and dated by an authorized representative of the brand owner.

Also note that the brand authorization letter needs to be submitted in an acceptable format, such as a PDF document on the brand owner's letterhead. Other supporting documents like invoices or inventory records are not acceptable as a brand authorization letter.

It's important to ensure that your brand authorization letter contains all the required elements and is submitted in the proper format. If you're still having issues, I recommend reaching out to Amazon seller support for further guidance.

Please let me know if you have any other questions! I'm happy to provide additional assistance to help resolve this issue.
