" up to now all movements within the EU have been regarded as internal"

CITES was signed by national governments, AFAIK the EU is NOT a signatory [The EU is not a Government - although sometimes it thinks and acts as though it is]. Therefore if what you state is correct then those EU nations are in flagrant violation of the terms of this treaty [The UK certainly isn't according to the link you provided] .

The opening post contained a link which included the following statement - "UK-bands-NOW-have-to-pay-import-duty-and-VAT-on-ALL-merchandise-before-even-entering-Europe-to-tour" - Ehmmmm No they don't as far as European countries in the EU and EEA are concerned. The articles linked to to support this contention all say that this is what MAY happen in the future in which no deal is ever negotiated [UK could leave the EU on 31.10.2019 with no deal, but that does not mean that some form of a trade deal could not be negotiated at a later date].
