How to complete certain data elements on your declaration
Mismatches between your licence and your declaration can cause delays to your goods movements.
In all cases, if the information does not match, then your goods may be subject to a hold or an inspection when it arrives in Northern Ireland.
Data element — 2/3 Documents and certificates
If the reference is not completed correctly:
the licence cannot be validated
your declaration will be rejected
you will not receive a Movement Reference Number (MRN) and will not be able to continue moving your goods
The Common Health Entry Document (CHED) reference format must be letters followed by numbers and include the full stop character. For example, ‘CHEDA.XI.2025.1234567’.
You should make sure that the information you include in this data element on your declaration matches the licence.
Data element — 6/2 Supplementary Units/SW Measurement Unit Code
You should make sure that the information you include in this data element on your declaration matches the licence.
Data element — 6/14 and 6/15 Commodity Codes
You should make sure that the information you include in this data element on your declaration matches the licence.
You must resolve any mismatching data elements before you can process the goods or use them for their intended purpose, even if the goods are moved away from the border under customs control. You may get a penalty if you do not resolve any mismatches.
If there is a problem with your declaration
You will receive a notification from the Customs Declaration Service (CDS) if there is a problem with your declaration. For example, when:
a valid certificate or licence for your goods cannot be found (this will be checked at the pre-lodgement stage)
there is a mismatch between the data supplied on your declaration and the relevant licence or certificate (during the crossing)
your licence has insufficient quantity remaining (during the crossing) — when you have used all the allocation available for your licence
Before your goods arrive, you should:
check your supporting licence
amend your declaration, if you need to
respond to any messages you receive from the Customs Declaration Service (CDS)
If your software does not allow you to amend your declaration, you need to cancel your declaration and submit a new one.
If you’re using the Trader Support Service for your licensed goods movements, you should contact them to help you.
If you need to report for an inspection
If you are a driver or haulier and you may need to report for an inspection:
the Goods Vehicle Movement Service (GVMS) driver messaging service will notify you
You must report for an inspection where a DAERA or Border Force control has been applied. In the case where the hold is due to a data element mismatch between declarations and your licence, HMRC may conditionally permit goods to leave the port and proceed to your end destination under customs control after all inspections have taken place. This is on the condition that the declarant must correct the mismatches before they are used for their intended purpose or processed.
Hauliers, if not acting as the declarant for the goods, should contact the consignee or importer to inform them.
