Grouping of crops based on taxonomic and/or agronomic similarity is a practical solution for the establishment of Maximum Residue Limits (MRLs) for similar crops and has been a major asset in addressing minor use and specialty crop needs.  Data from representative commodities are extrapolated to the entire group of related crops, including minor crops that might not be supported otherwise.  The Global Minor Use Summits continue to recommend that Codex serve as a model for crop grouping where the Codex principles for the selection of representative commodities be used for extrapolation to commodity groups.  With a great deal of effort, the Codex Committee on Pesticide Residues has adopted these principles along with updated fruit, vegetable and legume plant commodity type groups.  The Codex updates should serve as a valuable tool not only for JMPR reviewers but also for data generators who use Codex.  As other countries revise or create a crop grouping system, they are encouraged to adopt the new Codex principles and crop groups to the greatest extent possible, rather than creating a unique system. <br/> <br/>This paper will also provide outcomes from the Third minor use summit that took place in 2017.   Topics such as; considerations for a global list of exempt compounds (biopesticides), use of APEC-like procedures to expedite import tolerances, and considerations for a global MRL database. A brief report on a survey to define minor uses and progress on several global capacity building residue projects.
