(3) In the case of a veterinary medicinal product imported from another country, if the veterinary surgeon has not obtained a certificate from the Secretary of State under regulation 25(5) permitting importation, the veterinary surgeon must obtain a certificate from the Secretary of State before administration.
(4) All substances included in a medicinal product administered to a food-producing animal under the cascade must be substances for which a maximum residue limit has been established under Regulation (EC) No 470/2009 of the European Parliament and of the Council or substances which do not fall within the scope of Regulation (EC) No 470/2009 of the European Parliament and of the Council.
