General

Export MRN / Previous Documents

Impact	Background	Workaround
Using document type ‘N830’ in the Previous Document data group at any declaration level restricts the Office of Destination options to only those which also function as an ‘Office of Exit’ (from the customs territory of the EU).	The TAXUD EU Export Followed by Transit process for goods being exported from the customs territory of the union is triggered by provision of document type N830 in the Previous Document data group at any declaration level. The N830 code can only be provided at House Consignment level. The code N830 should only be used at the House Consignment level in the Previous Documents/Type data element if intending to indirectly export goods from XI.	Traders should refer to UK Specific Rules GB001 and XI001, which explain the acceptable UK methods for providing the Export MRN in a transit declaration.

R0855

Impact	Background	Workaround
If R0855 is not followed as described in the NCTS6 Technical Interface Specification, the NCTS will still release the transit without rejection. However, the movement could fail at subsequent Offices of Transit or Destination in other national administrations.	Due to a TAXUD reported error with the NCTS specification, R0855 is to be disabled by all administrations until it can be modified. The rule renders it impossible to submit a declaration with Departure Transport Means greater than 1x, unless an appropriate Inland Mode of Transport has been declared. This is contrary to TAXUD’s instruction that Departure Transport Means should be declarable over 1x even if Inland Mode of Transport is not declared. Unfortunately, as rule R0855 appears to still be active in other National Administrations, it must be followed when submitting declarations in the UK to avoid rejections at the Office of Transit and Destination.	To avoid errors caused by this rule please either follow the rule as defined in the TIS (unmodified from the TAXUD specification), or, even if inappropriate to the logistics of the declaration provide an Inland Mode of Transport type 3 (Road) to ensure that Departure Transport Means multiplicity (up to 3x) may be used for all declarations. This has been agreed by TAXUD as acceptable until the rule is modified and Inland Mode of Transport is not essential for Departure Transport Means multiplicity.

Resolved Errors

System

BST

Impact	Background	Workaround
Unloading Remarks were blocked between 00:01 and 01:00 during BST.	NCTS is aligned with Co-ordinated Universal Time (UTC) which is one hour behind BST. Due to this, any unloading remarks completed between 00:01 and 01:00 during BST were blocked, as they wereconsidered by the NCTS service to be made in the future.	Please Note: This issue was resolved with the implementation of the NCTS 6 Bridging Release (NCTS 6.1.5.1-P.3.1) 01 September 2025. Previous workaround Enter the previous day’s date when entering unloading remarks between the hours of 00:01 and 01:00. This workaround should be disabled on the day from 02:00 when the UK reverts back to Greenwich Mean time which will naturally align with UTC.

Pre Lodgement

C0404

Impact	Background	Workaround
Consignment - Place of Loading must be provided in the IE170 in all pre-lodged (additional declaration type D) declarations. It cannot be sourced from the IE015 or IE013 by the UK NCTS. Failure to provide the data element previously resulted in movement release, but failure at the Office of Transit and Destination.	Rule C0404 originally specified that Consignment - Place of Loading could exist in either the IE015, IE013, or IE170. This functionality has not been implemented to the UK NCTS.	Please note: This issue is resolved in NCTS 6 through the introduction of rule C0410, which refines the application of the Place of Loading requirement. While rule C0404 previously made Place of Loading mandatory in all cases, C0410 introduces conditional optionality by referencing a new code list (CL289 – CountryPlaceOfLoadingNotRequired). This means Place of Loading is no longer required where the Office of Departure is in a country listed in CL289. The definition of C0404 has been modified in the TIS to reflect this position. The data element, Consignment - Place of Loading, must be provided in the IE170 in all instances, regardless of it being provided in a previous IE015 or IE013. If the data element is not provided, currently no IE056 will be produced to prevent the declaration from being released. If it is released, the electronic process will not function at the Office of Transit or Destination. This behaviour has been altered in the so that failing to provide the data element, if required, in the IE170 will result in an IE056 rejection citing rule C0410.
