Investigating
HMRC have confirmed that CDS is back online; however, we are still experiencing declaration failures due to a recent change to CDS that was not communicated by HMRC in advance. We are currently in discussions with them to understand what changes are required and why this update was not notified before it went live.
We will update this page as soon as further information becomes available.
