To maintain the continuous movement of goods during a system outage or downtime, HMRC has released guidance how to proceed in the situation where the import declaration is not 'arrived' automatically by CHIEF or CDS for the goods imported at a location that uses Goods Vehicle Movement Service.

Please see the link for the detailed guidance:-

You do not need to take any action if:

• your pre-lodged import declaration has an arrived status
• you have declared your goods orally or by conduct
• you have made a declaration in your records
