In order to increase cross-border trade, the United States has entered into an agreement with Mexico and Canada to increase their de minimis shipping value. For the first time in decades, Canada will increase its de minimis level from C$20 to C$40 for taxes. Canada also expects duty-free shipments of up to C$150. Mexico will continue to provide $50 tax-free de minimis and will also offer duty-free shipments worth $117. Dissemination values up to these levels would occur with a minimum of formal entry procedures, making it easier for more businesses, especially small and medium-sized enterprises, to be part of cross-border trade. After the signing of the original agreement, nafta`s initial labor and environmental provisions were added as subsidiary letters in order to gain Democratic support and ensure the agreement was passed under the Clinton administration.

The text of the agreement was signed on 30 November 2018 by the Heads of State and Government of the three countries as a secondary event to the G20 Summit to be held in Buenos Aires, Argentina, on 30 November 2018.  The English, Spanish and French versions will be equally authentic and the agreement will enter into force after ratification by the three states through the adoption of enabling legislation.
