The answer is: Congress made a compromise tariff to satisfy Southern states
At that time, the Tariff of 1832 that created by the federal government was seen as unconstitutional by many southern states and they threaten to secede from united states if the federal government did not fix it.
In the end, the federal government choose to create a compromise by creating the tariff of 1833. The new tariff cut down the import taxes for the southern states until the next decade.
