An operation that wishes to become certified can apply for certification to any of the 98 certifying agents located anywhere in the world. Organic operations must maintain an organic system plan (OSP) that has been agreed to by the certifying agent. This plan must include descriptions of how the operation will meet NOP regulations, including descriptions of monitoring practices, materials to be used in organic production or handling, and procedures to prevent the commingling or contamination of products in a split operation.
