Concern for quality will remain high. Achieving higher quality standards is costly and is characterized by economies of scale. For example, grading and sorting have lower cost per unit in large operations. The U.S.-Mexico economic integration faces impediments in transportation services, though free trade in transportation services should have been in place by now. In addition, many delays exist in both directions.
Delays make fresh products vulnerable but are less of a problem for grains.
The Mexican railway system is still undercapitalized, because of past neglect prior to privatization. For example, intermodal connection with trucking and ocean shipping is lacking, and better connections would increase the relative advantage of railways. Larger and better facilities would help alleviate some of the bottlenecks at border points. More customs personnel would help, too. Finally, Mexico has yet to build better roads to be on a par with U.S. roads.
