On December 18, 2008 Mexico’s competition authority, the Comisión Federal de Competencia (CFC), announced its initiation of an investigation to determine whether ground freight companies have engaged in monopolistic practices in violation of the Federal Competition Law. More than 80 percent of commercial trade between Mexico and the United States and 75 percent of the merchandise circulating around Mexico is transported by ground (i.e., by trucks on highways). Article 31 of the Federal Competition Law provides the CFC with the power to conduct on-site verifications where necessary to assist in its analysis of the industry.
