The MRA between Switzerland and the United Kingdom is an integral part of the "Trade Agreement between Switzerland and the United Kingdom of Great Britain and Northern Ireland" (CH-UK Trade Agreement) (Art. 1 let. d in conjunction with Art. 2 let. b and Annex 3). It covers three product areas: Motor Vehicles, Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) Inspection for Medicinal Products and Batch Certification. These three product areas covered by the MRA Switzerland-EU were incorporated into the trade agreement with the United Kingdom, as the standards underlying the technical regulations were developed within the framework of international organisations of which both Switzerland and the United Kingdom are members. These international organisations are: the UN Economic Commission for Europe for motor vehicles, the OECD Principles for Good Laboratory Practices for good laboratory practice and the Pharmaceutical Inspection Cooperation Scheme (PIC/S) for good manufacturing practice (GMP) inspection. In these three product areas, the agreement replicates the rights and obligations under the Switzerland-EU MRA; these product areas function in the same way in relation to the UK as they do in relation to the EU.
The 17 remaining product areas covered by the MRA Switzerland-EU were not taken over into the trade agreement due to the unconfirmed equivalence recognition between the EU and the UK`s technical regulation.
