Ers hynny, mae’r Rheoliadau hyn wedi’u hadolygu’n gyson ac mae nifer o newidiadau wedi’u gwneud i’r rhestr o wledydd a thiriogaethau sydd wedi’u heithrio. Y newid mwyaf diweddar oedd dileu’r holl wledydd a thiriogaethau o’r rhestr hon ar 18 Ionawr 2021.
Since then these Regulations have been kept under review and a number of changes to the list of exempt countries and territories have been made, most recently to remove all countries and territories from this list on 18 January 2021.
