MRLs in Northern Ireland
Under the Northern Ireland Protocol to the Withdrawal Agreement (NIP), EU law applies in Northern Ireland.
EU MRLs apply to food or feed produced in or imported into and marketed within Northern Ireland. Any EU decisions on MRLs will apply in Northern Ireland.
If the proposed use of a PPP (plant protection product) in Northern Ireland may lead to residues exceeding the EU MRL, you must apply to change the EU MRL before use of the PPP can be authorised.
To import produce into Northern Ireland with residues exceeding the EU MRL, you must apply for an import tolerance before importing treated produce.
