Trying to understand when a tariff is actually imposed & paid on goods coming into the US.
The Trump administration has announced at various times changes in tariffs to be imposed on certain goods arriving from China. For example the previously announced tariff increases on Chinese electronics that were to be effective September 1 2019 was postponed.
Had those tariffs gone into effect, I am presuming (perhaps incorrectly) that a shipment of such goods that arrived and processed by customs prior to midnight on Aug 31 would have be charged at one level, while another shipment (regardless of arrival date) hat had not yet been processed by customs before midnight Aug 31 would have been charged at a different level. Is this an accurate understanding?
It has been suggested that an importer can pay a tariff in advance of actual arrival at a US port. Is that accurate?
It has also been suggested that importers "can run a tab" with customs, that is not actually pay the tariff at the time of customs clearance, but rather submit payments against invoices presented by the Treasury (on behalf of Customs) on (say) a quarterly basis. (in other words, potentially well after the goods are in country and being distributed). Is that accurate?
