The effects of Brexit on imports

If a no-deal Brexit occurs, the import of animals and foodstuffs of animal origin, fertiliser products, feedingstuffs and plants from the United Kingdom will be controlled the same way as imports from any other non-EU countries. For example, when fertiliser products and feedingstuffs are imported from outside the EU, the operators are subject to certain obligations, such as the filing of a pre-import notice.
