His Majesty's Revenue and Customs (HMRC) has issued comprehensive updates to its guidance for completing import declarations via the Customs Declaration Service (CDS). These revisions provide detailed instructions for various data elements, aiming to streamline and clarify the submission process for businesses and declarants. The updated documentation specifically addresses all eight groups of data elements, from message information and procedure codes to transport details and other statistical data, offering a complete framework for UK import declaration data elements.

This updated guidance is exclusively focused on import declarations and does not extend to export customs declarations or Customs Clearance Requests (CCR) inventory releases, which were previously known as C21s. While the instructions incorporate known error workarounds where applicable, the primary objective is to enhance accuracy and compliance across the board. The extensive nature of these amendments necessitates a thorough review by all parties involved in international trade.

Among the significant changes are declaration simplifications affecting multiple data elements, including 1/9, 3/19, 4/11, 5/26, 5/27, 6/9, 6/11, 6/13, 7/2, 7/5, and 7/15. These adjustments are designed to simplify aspects of the declaration process, potentially reducing complexity for businesses. However, understanding the precise implications of each change is crucial for maintaining compliant submissions.

A critical area of revision concerns Postponed VAT Accounting (PVA), with amendments made to various parts of the Declaration Completion Instructions related to PVA01 and the subsequent removal of the PVA01 workaround. Furthermore, Data Element 3/40 has been updated to provide a clearer example for manual duty calculations when utilizing Postponed VAT Accounting, reflecting the ongoing UK Postponed VAT Accounting CDS changes. EORI numbers from EU countries became permissible for declaration in certain data elements from July 4, 2026, a significant development for cross-border trade and EORI numbers EU CDS July 2026.

Several other specific data elements have undergone important modifications. Data Element 2/3, found in 'Group 2: References of Messages, Document, Certificates and Authorisations,' now reflects the establishment of the Department for Business, Innovation, Science and Trade (BIST) and includes new guidance on the use of document codes 9L51 and 9Y17. Data Element 4/17 has been updated to emphasize that a declared preference code must be compatible with the corresponding commodity code; failure to ensure this alignment will result in the rejection of the declaration. Additionally, the commodity codes usable with Additional Information Code COMNE have been revised, and Data Element 2/2 has received corrections and clarifications regarding Country of Dispatch codes for AI Code NIDOM, as well as guidance for AI Code EUPRF concerning Country of Origin and Country of Preferential Origin completion.

Further adjustments include Data Element 6/18, where negative values are no longer permitted for specific movements. Data Element 5/15 is now always mandatory, and Data Element 5/16 must also be completed when claiming preference, even if the country codes in both DEs are identical. Data Element 6/10 now mandates that its value must always be greater than or equal to zero, and the notes section for Data Element 4/15 (Exchange Rate) has been refined to accurately reference the correct data element. These detailed Customs Declaration Service import amendments underscore the need for precise data entry.

The breadth and detail of these HMRC CDS import declaration guidance updates mean that businesses and individuals responsible for import declarations must meticulously review the revised instructions. The changes are not merely administrative; they carry direct implications for compliance, potentially leading to declaration rejections and penalties if not properly understood and implemented. The requirement for preference codes to align with commodity codes in DE 4/17, for instance, introduces a critical validation step that declarants must now actively manage.

Compliance officers and trade lawyers must meticulously review these updated HMRC CDS import declaration instructions to ensure accurate and compliant submissions, particularly noting changes to specific data elements, Postponed VAT Accounting, and the EORI number rules for EU businesses that came into effect from July 4, 2026, to avoid declaration rejections and penalties. The removal of the PVA01 workaround and the updated guidance for manual duty calculations using Postponed VAT Accounting are particularly relevant for financial and accounting departments. Furthermore, the change regarding EU EORI numbers that took effect in July 2026 requires forward planning to ensure systems and processes are ready for the new requirements.

Ultimately, these revisions underscore HMRC's ongoing efforts to refine the Customs Declaration Service. Staying abreast of these changes is not just about avoiding errors; it is about ensuring the smooth and efficient flow of goods, maintaining legal compliance, and preventing unnecessary delays or financial repercussions for importing businesses.
