I intend to sell a product containing a bath bomb, a candle and a soap bar. It will be a private label product and will be produced in and imported from China. I am working closely with a trading company who are providing and labelling these products for me. I have carefully reviewed the FDA labelling guidelines to ensure the product complies and have read the amazon guidelines here: https://sellercentral.amazon.com/help/hub/reference/G200164470.

I have created a sample listing but I was not required to upload any additional documentation at the time of creation.

Just so I am prepared, what kind of documentation will I be expected to provide further on down the line for these items? I seen a reference elsewhere to needing to provide a purchase invoice. Do I need to get the trading company/manufacturer to provide any additional documentation/safety information for the product?

Thanks!
