HMRC: GB, NI Entry Summary Declaration Requirements Explained

• Entry summary declarations are mandatory for goods entering Great Britain, or Northern Ireland from Great Britain or non-EU countries.
• The carrier is responsible for submitting declarations up to 200 days before arrival, with some exemptions for qualifying Northern Ireland goods.
• The S&S GB service is used for Great Britain imports, requiring a GB EORI number for non-GB established businesses.
• The ICS2 system handles Northern Ireland imports, including specific parcel movements under the Windsor Framework, and requires a GB or XI EORI number.
• Both S&S GB and ICS2 require compatible XML software for submission, or businesses can use the Trader Support Service for Northern Ireland declarations.

The primary responsibility for ensuring these declarations are submitted rests with the carrier transporting the goods, underscoring the importance of robust compliance procedures within logistics operations.

Businesses engaged in the movement of goods into specific UK territories are mandated to submit an HMRC entry summary declaration. This critical customs requirement applies to all consignments entering Great Britain, as well as those arriving in Northern Ireland from Great Britain or from any country outside the European Union. The primary responsibility for ensuring these declarations are submitted rests with the carrier transporting the goods, underscoring the importance of robust compliance procedures within logistics operations.

While the general rule necessitates these declarations, certain exceptions exist. Notably, qualifying goods originating from Northern Ireland and subsequently imported into Great Britain are exempt from this specific declaration requirement; however, non-qualifying Northern Ireland goods moved to Great Britain have required an entry summary declaration since 31 January 2025. For all other applicable movements, the declaration must be filed prior to the goods' arrival, with the flexibility to submit it up to 200 days in advance, allowing for strategic planning in supply chains.

The submission of these vital UK customs safety security declaration documents relies on specialized digital platforms. For imports into Great Britain, the Safety and Security GB (S&S GB) service is the designated system. Conversely, goods entering Northern Ireland from Great Britain or non-EU countries require submission through the Import Control System 2 (ICS2). A key technical consideration for both systems is the absence of a direct user interface, meaning businesses must utilize compatible software capable of generating XML (eXtensible Markup Language) messages, or alternatively, develop such software in-house.

Before accessing the S&S GB service, users must possess sign-in credentials, which can be established during the registration process. Furthermore, any business not formally established within Great Britain is required to obtain an EORI number GB registration. This unique identifier is crucial for all customs-related activities. When submitting an S&S GB declaration, comprehensive details about the consignor, consignee, and a precise description of the goods are mandatory.

For goods destined for Northern Ireland, the ICS2 import Northern Ireland system is the central platform for entry summary declarations. This system is particularly relevant under the Windsor Framework parcel customs arrangements, where specific parcel movements from Great Britain into Northern Ireland will also necessitate an entry summary declaration. Businesses operating in this context will need either a GB or XI EORI number to facilitate their submissions.

An alternative for businesses moving goods into Northern Ireland is to leverage the Trader Support Service (TSS), which can submit entry summary declarations on their behalf. Opting for the TSS eliminates the need for separate ICS2 registration, streamlining the compliance process. For any specific inquiries or assistance regarding ICS2, HMRC provides a dedicated email contact at ics.helpdesk@hmrc.gov.uk.

Adherence to these HMRC entry summary declaration requirements is paramount for avoiding customs delays and potential penalties. Carriers and importers must ensure that declarations are not only submitted on time but also accurately reflect the consignment details. In instances where both a carrier and a third party file declarations for the same shipment, customs authorities retain the discretion to accept either submission or request further clarification, highlighting the need for clear communication and coordination among all parties involved.

To safeguard against operational disruptions, businesses are strongly advised to ensure that multiple team members have access to all enrolled HMRC services. This redundancy is critical to prevent declaration delays that could arise if a primary administrator is unavailable or departs the company. Furthermore, all imports necessitate the provision of relevant supporting documents and licenses, which must be readily available for customs verification.

This guidance outlines critical compliance obligations for businesses importing goods into Great Britain or Northern Ireland, including specific system requirements (S&S GB, ICS2) and responsibilities for declaration submission. Lawyers and compliance officers must advise clients on these updated customs procedures, particularly concerning the impact of the Windsor Framework on NI parcel movements, to ensure adherence and avoid delays or penalties.
