Import Tolerances & Maximum Residue Levels

Crop consultant analyzes corn plants mid-summer. Exponent consultants help improve yield and safety of ag products.

Meet exceedingly stringent residue and import tolerance regulations

Maximum residue limits (MRLs) and import tolerances (ITs) are important trading standards that relate to pesticide residues in food and are a critical component of consumer safety. With extensive technical experience with such submissions to regulatory authorities in the U.S., Canada, Mexico, European Union, Australia, New Zealand, Japan, South Korea, and Taiwan, Exponent is uniquely positioned to provide you with regulatory advice and to make MRL and IT submissions to regulatory authorities around the world.

Global, full-suite IT and MRL compliance support.

With increasing legislation related to MRLs and ITs in a wide range of countries and jurisdictions across the world, it is important to partner with a scientific and engineering firm that has both technical knowledge and an understanding of the specific regulatory needs of importing countries. Increasingly, growers, importers, exporters, distributors, and retailers are involved in agrochemical product development and food supply chains and need to be assured that the appropriate MRLs and ITs are in place to allow free movement of agricultural produce from growing regions to target markets.

Having provided regulatory advice and worked with regulatory bodies around the world, including the Joint FAO/WHO Meeting on Pesticide Residues, Exponent offers a coordinated approach to supporting multiple location submissions. Additionally, Exponent provides support in the newly developing area of European biocides MRLs.

Our consultants provide a complete dossier support service, including providing appropriate summaries of relevant data, such as toxicology, metabolism, and residues studies. We also perform consumer risk assessments using appropriate models to calculate and propose levels for MRLs and import tolerances. Further, Exponent can place and monitor residue trials or other studies (including the pharmacology study required for import into Japan) if such data are required to complete your dossier/submission.
