The main purpose of the 2023 Regulations is to: (a) allow treated seeds to be placed on the market and used in GB as long as the PPP used to treat them was authorised for that use in at least one EU or EEA Member State immediately before IP completion date for a further 3.5 years and; (b) allow permits to be issued, by the GB regulator, for any PPP for a further 2 years if there was a valid Parallel Trade Permit (PTP) in place on 31 December 2022 provided that the GB reference product is still authorised.
