It is in the best interest of all parties to avoid disrupting global commerce as,
in the words of the EDPB in its press release:
… the duties for the competent supervisory authorities (SAs)
to suspend or prohibit a transfer of data to a third country pursuant to SCCs, if, in the view of the competent SA and in the light of all the circumstances of that transfer, those clauses are not or cannot be complied with in that third country, and the protection of the data transferred cannot be ensured by other means....
If the result of this assessment is that the country of the importer does not provide an essentially equivalent level of protection, the exporter may have to consider putting in place additional measures to those included in the SCCs.
The EDPB is looking further into what these additional measures could consist of.
Schrems II requires effective mechanisms to ensure compliance with the level of protection essentially equivalent to that guaranteed within the EU by the GDPR and that transfers of personal data pursuant to such clauses are suspended or prohibited in the event of the breach of such clauses or it being impossible to honour them.
