Provisions of the agreement cover a wide range, including agricultural produce, homelessness, manufactured products, labor conditions, digital trade, among others. Some of the more prominent aspects of the agreement include giving US dairy farmers greater access to the Canadian market, guidelines to have a higher proportion of automobiles manufactured amongst the three nations rather than imported from elsewhere, and retention of the dispute resolution system similar to that included in NAFTA. Dairy The dairy provisions give the U.S. tariff-free access to 3.6%, up from 3.25% under the never-ratified Trans-Pacific Partnership, of the $15.2 billion (as of 2016) Canadian dairy market. Canada agreed to eliminate Class 7 pricing provisions on certain dairy products, while Canada's domestic supply management system remains in place. Canada agreed to raise the duty-free limit on purchases from the U.S. to $150 from the previous $20 level, allowing Canadian consumers to have greater duty-free access to the U.S market. Automobiles Automobile rules of origin (ROO) requirements mandate that a certain portion of an automobile's value must come from within the governed region. In NAFTA, the required portion was 62.5 percent. The USMCA increases this requirement by 12.5 percentage points, to 75 percent of the automobile's value. The initial proposal from the Trump administration was an increase to 85 percent, and an added stipulation that 50 percent of the automotive content be made by United States auto manufacturers. While the deal's text did not include the more demanding version of this provision, there is concern that the increased domestic sourcing, aimed at promoting US employment, will come with higher input costs and disruptions to existing supply chains. De minimis To facilitate greater cross-border trade, the United States has reached an agreement with Mexico and Canada to raise its de minimis shipment value levels. Canada will raise its de minimis level for the first time in decades, from C$20 (US$) to C$40 (US$) for taxes. Canada will also provide for duty-free shipments up to C$150 (US$). Mexico will continue to provide US$50 tax-free de minimis and also provide duty-free shipments up to the equivalent level of US$117. Shipment values up to these levels would enter with minimal formal entry procedures, making it easier for more businesses, especially small- and medium-sized ones, to be a part of cross-border trade. Canada will also allow 90 days after entry for the importer to make payment of taxes. Labor USMCA Annex 23-A requires
