How did northern and southern states compromise regarding the power of Congress over foreign trade and taxes?

Northern and southern states compromised on Congress's power over foreign trade and taxes during the Constitutional Convention by agreeing to allow Congress to regulate interstate and foreign commerce while placing limits on its ability to impose export taxes. This compromise addressed the northern states' interest in promoting trade and commerce while protecting the southern states' agricultural economy, which relied heavily on exports. Additionally, the agreement included a provision that prohibited Congress from banning the slave trade for a specified period, further easing tensions between the two regions.
