If you notice the CDS error code CDS40013 whilst submitting your declarations, it means that the incorrect information has been entered in a data field.

One of the most common causes of this is where the wrong commodity code has been entered in the declaration. The UK and NI commodity codes were updated on 1 January 2022.  If you use a commodity code that is no longer valid whilst completing a supplementary declaration you will receive the error code CDS40013.  To correct this, please check and ensure you are using the latest commodity codes.
