tariffs etc of stuff coming in from outside the EU are set by deals made by the EU. So I guess the idea is that the UK will be able to make different deals in future?
Tariffs on imports coming from countries without an EU trade agreement are set at the rates on the EU’s tariff schedules.
The UK has exactly replicated those tariffs in its own proposed schedules, so there would be no change in import tariffs.
Likewise we are currently part of the EU so exports from the UK are subject to tariffs in non EU countries based on deals made by the EU
UK exports to countries under EU trade agreements will give preferential tariff rates, otherwise exports are subject to the importing countries own standard tariffs.
Leaving the EU means we lose all of those preferential deals and either fall back onto the standard tariffs (WTO) or hope that DExEU has pulled its finger out in terms of new arrangements.
Also remembering that tariffs are only part of the issue - non tariff barriers will be the big headache.
1 we an remove the 26 percent tariff on dairy protect helping the poorest in society
The UK’s WTO schedules replicate the EU schedules, so that‘s not going to happen. Nor would the UK unilaterally set its tariffs to zero.
2 the us is the biggest trading partner of the uk
Only if you count each EU country separately, as UK trade with the EU27 is about 5 or 6 times higher than with the US. Which is not surprising given the gravity effect.
