All news about Brexit and what is to come made me curious. I heard that import from Great Britain should have to pay custom duties. Could EU impose on Sweden to levy tariffs on our import from Great Britain?

I learned that EU is a customs union. Tariffs are paid on import because of a number of sophisticated reasons to protect us Europeans. To protect developing countries EU will be restrictive on allowing subsidies to export of agricultural products.

EU makes a point of being in favour of free trade and free market economies. And still EU allows subsidies and tariffs.

Is Sweden still exporting milk powder with subsidies, although with restrictions?
