Hi

I was planning to sell supplements on Amazon UK, but when I click 'request approval' I am met with the following message

'We are not accepting applications to sell:

Other product(s)

Other Health & Personal Care category in Used, Refurbished, Collectible condition(s)'

I thought it was a technical issue so contacted Amazon, who have replied stating

'To maintain a safe and trustworthy shopping experience, certain products cannot be listed or sold on Amazon or may be subject to additional requirements because of supply chain authenticity risks.

Your account does not currently meet the criteria required to list these products due to account metrics, distribution pathways of the brand, or other factors.

we are currently not accepting applications to sell these items. We will not be able to provide any further information at this time.'

I would be ok with the refusal, if they could provide me with actual reason why they won't allow me to sell them? If they wanted certificates or 3rd party testing ect I would do this, but they have no interest in providing any sort of criteria for me to apply to sell them. My question is to anyone with experience in this area, How do I become Eligible to sell Supplements on Amazon UK?
