The real question on NAFTA and agriculture

The disruption of NAFTA withdrawal could affect family farmers on both sides of the border. Under WTO rules, Mexico has the right to raise tariffs substantially on many farm goods. The U.S. has mostly committed to lower tariff ceilings, but there are some exceptions, such as imports of red meat, for which the U.S. currently applies a 18 percent tariff on imports from non-NAFTA countries. However, both countries could decide to apply tariff rates (which would apply to all trading partners) that are much lower than the ceilings they have committed to under the global trade rules.
