The way I see it, it is more like a very-high initial negotiation position. From here on, each country will be dealt with individually. You accept our terms and get 5% discount on tariff ! Every country has a set of red lines. Fewer the red lines better they will be placed in one-to-one "trade agreements".

EDIT: Someone from white-house explicitly declined tariff to be a negotiation. Next few days will be interesting.
