N/L means that the chemical (or sum) is not legislated in that country, therefore no specific MRL has been established for this active ingredient/commodity pair. MRLs are obtained from an external database and are for reference purposes only. The country’s specific regulations governing the active ingredient/commodity should always be consulted.   

Each country is unique in the way they define chemicals and regulate their MRLs. Some countries may require a sum of different chemicals be used to determine MRL compliance. AGQ Labs list all sum parameters on the last page of our reports. Please contact your AGQ Labs service representative for specific questions.
