In 2006, the U.S. Department of Agriculture (USDA) issued a proposed interim rule, which would remove the current exemption from inspection for imported fruits and vegetables grown in Canada and the exemptions for all transport modes from the agricultural quarantine and inspection (AQI) user fee for traffic entering the U.S. from Canada.
Il est prévu que la réglementation définitive de la TSA et de la PHMSA sera émise vers la fin de 2007.
