My account has been deactivated. I have a third party company that put branded products on my account. Amazon needs information from the third party to verify they have or I have authority to sell those products. I cannot get the third party to respond and do not know what to do. I don't have access to their purchasing documents. Is there anything I can do?

I'm based in Australia, but I'm looking to sell and target US-based customers. I plan to follow the online arbitrage as my business model and use FBA as my fullfillment method.

Being based in Australia, it's unpractical to have the item shipped to my address to be prepared for packaging and labelling in an Amazon warehouse. Usually, following the online arbitrage model, the seller purchase and sends the product directly in their address before preping and sending it to an Amazon warehouse for further processing. Being based in Australia, it would be really expensive to have the item be shipped from the USA to Australia and then have that item sent be sent to an Amazon warehouse. I can't do the preping myself, so I have to rely on a third party warehouse to do the job.

Are there any third party warehouses in the US that specializes in Amazon FBA? I plan to purchase the product then send it directly to this third party to be prepped before sending it to an FBA center.

I sincerely believe it's because Amazon constantly screws with their algorithms. Their eventual plan is to phase out third party sellers.
