What compromise was made at the constitutional Convention so that Congress to get the power to control foreign trade

The compromise that was made at the constitutional Convention so that Congress could get the power to control foreign trade was that Congress could not tax exports. What exports means is to send products or goods to another country, while imports means getting goods from other countries. The reason why that would be your answer is because to send things over seas to foreign countries, it would cost a lot, and if they were to tax it, it would be very expensive to export things. Because of the compromise, Congress doesn't have to tax products or things when exporting them to foreign countries, which saved them A LOT of money. Because of not taxing exports, they gained so much power exporting things.
