IAF members are expected to manage the impact of sanctions with their accredited CABs, which typically will include informing them to abide by the (US, national, regional and international) sanctions and/or communicating any IAF notification to them.
It would be up to each IAF member AB if they want to require their CABs to confirm with the AB their status and activity. IAF is not requiring that level of follow-up, it expects ABs to manage as appropriate, as outlined in the 13 May 2022 statement.
