This report Review of the Regulation of Freight Transport in Mexico is a response to the 2012 Recommendation of the Council on Regulatory Policy and Governance. Mexico's Ministry of Economy and Federal Commission for Better Regulation (COFEMER) asked the OECD to carry out a review to identify regulatory barriers, obstacles, implementation flaws or inefficiencies affecting the freight transport sector in Mexico. The objective of this review, therefore, is to generate recommendations for improvement using as basis good international practices. These recommendations will be used to prepare a set of legal reforms for the road transport, rail, civil aviation, ports and border management sectors. The goal is to promote economic efficiency, productivity and growth. This study is carried out as part of a broader programme of co-operation among the Ministry of Economy, COFEMER and the OECD to strengthen competitiveness in Mexico through regulatory improvement. The Review finds several regulatory challenges across the different means on transport. For instance, on road transport the modification of regulation on limits on weigh and dimensions should be based on empirical evidence and on a clear indication that the benefits of any regulatory restriction outweighs the potential costs. In rail transport, the Review suggests that authorities should develop the capacity to collect and analyse data needed to form judgements on competition issues. Similarly, on issues on ports, the Review finds that the lack of infrastructure coupled with legal controls and administrative procedures create unnecessary bottlenecks in the release of cargo, hence affecting efficiency of transport and increasing costs for businesses.
