Can I export live wild-capture Live Bivalve Molluscs for depuration purposes after the end of the Transition Period?

EU EHCs currently allow movements of un-depurated wild-capture LBMs between Member States, but not from third countries into the EU. A revised aquaculture certificate is expected to come into force from 21 April 2021, which will allow this trade to take place from third countries into the EU.
However, under the EU rules regarding movements of animals from third countries, as the UK will be classed from 1 January 2021, GB businesses that export, or intend to export, wild-caught Class B/C LBMs will be unable to do so from 1 January until the introduction of the relevant certificate, expected on 21 April 2021. LBMs from GB aquaculture businesses in Class B waters will be unaffected.
