Re: Will it work?
You buy stuff from a local farm, and sell it in your shop. That is taxable in the UK, because the activity takes place there.
Farm UK Ltd sells to Caymans Farm Inc, which sells to Johnny's Butchers Caymans Inc, which sells to Johnny's high-street mean emporium UK Ltd. The economic activity is now dispersed. Complicate that with a third jurisdiction and some other suppliers to the UK entity, and it's difficult to narrow down exactly where the economic value gets added - is it growing the cow, the branding on the packaging, the sale to the public?
What if you Amazoned is up a gear and instead of taking orders in the butchers and getting cash over the counter, you have a sales terminal at which the public order their meat direct from an offshore entity which then orders it form the uk entity to provide to the customer?
