NAFTA Guidance Document on Data Requirements for Tolerances on Imported Commodities in the United States and Canada

The purpose of this document is to provide detailed guidance on data requirements that meet the North American Free Trade Agreement (NAFTA) standards for the establishment of pesticide import tolerances or maximum residue levels (MRL) in Canada and the United States. This document has been developed consistently with the goals of NAFTA. A common NAFTA approach to import tolerances/MRLs will promote trade between North America and the rest of the world. This guidance began as a project of the three NAFTA countries; however, due to new regulations and resulting resource constraints in Mexico, it is at this time only a bilateral effort by the United States and Canada. View questions and answers related to the guidance.
