Federal legislation impacting international trade is primarily the result of the normal legislative process. The Congress will, for certain trade agreements, use the fast-track process in which the statutory language is considered without the possibility of amendment or change.
State legislation has little impact on international trade, except to the extent of leaw, such as liquor control, and areas such as trade promotion. Under the Constitution, trade policies and tariffs are delegated solely to the Federal Government.
The legislation of other nation states has a direct impact on trade with those nation states.
