Now that we know we are leaving the EU
(please keep in mind this information keeps changing as DEFRA makes decisions)
CITES permits are required from the exporting country and from the UK (give name and address) to import orchids from outside the EU to UK and currently the UK ones cost about £75 per genus. Exporting country CITES vary in cost and the exporter will normally arrange this. At the moment plants from the EU can come to the UK without any CITES permits.(currently until the end of 2020)
When we leave the EU all orchids from outside UK will need export CITES permits including from the EU and elsewhere as well as import permits from the UK.
