Y garreg filltir gyntaf a gynigir o ran rhoi'r Model ar waith yw cyflwyno ardystiad iechyd ar gyfer cynhyrchion anifeiliaid, planhigion a chynhyrchion planhigion risg ganolig, a bwyd a phorthiant risg uchel nad ydynt yn deillio o anifeiliaid, sy'n cael eu mewnforio o'r UE o 31 Hydref 2023. Ar yr un pryd, yng Nghymru byddwn hefyd yn cyflwyno'r gofyniad i rag-hysbysu ar gyfer rhai categorïau ychwanegol o nwyddau iechydol a ffotoiechydol sy'n cael eu mewnforio o Weriniaeth Iwerddon, gofyniad sydd eisoes ar waith mewn mannau eraill ym Mhrydain Fawr ers mis Ionawr 2022.
The first implementation milestone proposed is the introduction of health certification on imports of medium risk animal products, plants, plant products and high risk food and feed of non-animal origin from the EU from 31 October 2023. At the same time, in Wales we will also introduce the requirement to pre-notify some additional categories of SPS goods imported from the Republic of Ireland, a requirement already in place elsewhere in GB since January 2022.
