In calendar year 1990 Mexico imported 7.0 million metric tons of grain and soybeans, 92.2 percent of that from the United States. This report is an effort to document the quality standards for Mexico and the United States and the quality of U.S. grain (corn, sorghum, wheat, and soybeans) exports to Mexico. The quality data is summarized from inspections of exports to Mexico made by the Federal Grain Inspection Service during the period October 1985 to February 1992.
