New sellers will come under the 3 ASIN check where Amazon’s bot will select 3 of your listed ASIN’s and ask you to supply your invoices and possibly letter of authorisation from the brand. The invoice has to be from the manufacture, licenced distributor or a wholesaler that is acceptable by Amazon (Costco, Makro, majority of Alibaba won’t be accepted). If you are buying from Alibaba you need to be dealing direct with the manufacturer not a middle man. The manufacturer need to be VAT registered and be registered on their equivalent to UK’s Company House. You need to check that you have the necessary safety documents depending on the product and category. Your item with be going round a babies neck !!! All this you have to find out, Amazon won’t do the work for you, even if they allow you to list it they expect you to have done the checks and have the relevant certification, paperwork, safety measures etc.

You cannot just buy random cheap things from China or anywhere else without doing due diligence
