Except where it facilitates it by having substantial FTAs in place with places like Korea, Japan, Canada, etc.
Who is the World's number 1 producer of oranges? Brazil
Who is currently negotiating an FTA with Brazil? The EU
Who would have to apply WTO tariffs to any imports of oranges from Brazil? The UK
Are there countries which import Oranges to the EU in substantial numbers?
Why yes. South Africa (who have an FTA) and Egypt (who have an FTA)
Except they aren't. And in any case, its much better to favour Spanish oranges over Brazilian or South African oranges because we want to reduce food miles.
No they're really aren't. Oranges certainly aren't one of them. Only about a third of UK fruit imports come from the EU the rest from South America and Africa predominantly.
So overall grade on your analysis a C-. Much improvement needed.
