Amazon Brazil does require a deposit method to be bound when selling products. This is because Amazon requires sellers to bind a deposit method for timely refunds and settlements in order to ensure the smooth progress of transactions and protect the interests of both buyers and sellers.

However, the specific requirements and procedures may vary due to changes in Amazon policies. I recommend that you log in to the Amazon Brazil site and check the relevant policies of the Seller Center, or contact Amazon customer service for detailed and accurate information.

If you have other questions, please feel free to ask. I wish you a happy life!
