Two neighboring nations, Valoria and Novaria, currently operate under an agreement where all tariffs and import quotas between them are abolished, but each country independently sets its own tariff rates on imports from non-member nations. They decide to deepen their integration by adopting a unified schedule of tariffs applied to all imports originating from non-member countries, while keeping their bilateral trade duty-free.
