Who Needs Safety and Security Filings in GB?
Who needs safety and security filings for GB movements: ENS and EXS explained, carrier responsibility, what importers, hauliers and forwarders must provide, and how to make compliance manageable.

A track can reach the port on time, have the correct goods and documents, and still face a refusal at check-in because the required safety and security data has not been lodged. For businesses asking who needs safety and security filings, the practical answer is that responsibility usually sits with the carrier, but every party in the supply chain has a role in making sure the filing is accurate and submitted on time.
For Great Britain movements, safety and security requirements are separate from the commercial customs declaration. They are designed to give border authorities advance information about goods and transport before arrival or departure. That means an import declaration, transit movement or ferry booking does not automatically prove that the correct safety and security declaration has been made.
Who needs safety and security filings for GB movements?
A safety and security filing may be required when goods enter or leave Great Britain. Whether it is needed depends on the direction of travel, the route, the transport mode, the customs procedure and any applicable exemption.
For imports into Great Britain, the key filing is generally an Entry Summary Declaration, known as an ENS. Since 31 January 2025, ENS requirements apply to most goods imported into Great Britain from the European Union, as well as goods arriving from the rest of the world. This is particularly significant for businesses that previously moved goods between the EU and GB with relatively limited border administration.
The legal responsibility for submitting an ENS normally rests with the carrier - the party operating the active means of transport that brings the goods into Great Britain. Depending on the movement, this could be a shipping line, ferry operator, airline, rail operator or the haulier responsible for the vehicle crossing the border.
That legal position does not mean the importer can ignore the process. Carriers frequently need commodity, consignor, consignee, routing and transport information from the trader, freight forwarder or logistics provider. If that information is late, incomplete or inconsistent with other declarations, the movement can be held up before boarding or on arrival.
Importers, exporters and traders
An importer is not automatically the party that files the ENS, but they need to establish who does. If your business arranges collection from an EU supplier, uses an unaccompanied trailer service or controls the freight contract, do not assume that a carrier or forwarder has accepted the task. Confirm it in writing as part of the booking and customs process.
Exporters also need to understand the requirement when goods leave Great Britain. A full export declaration will often include the required safety and security information. However, an Exit Summary Declaration, or EXS, can still be required in specific circumstances where that information is not otherwise provided through an export declaration.
Examples can include certain movements of empty packaging, goods leaving temporary storage, some transit movements and other cases where goods depart without a conventional export declaration carrying the necessary data. The exact requirement depends on the facts of the movement, so a regular export route should be reviewed rather than managed on assumption.
Hauliers and transport operators
Hauliers are commonly closest to the operational risk. A driver may be the person turned away at a terminal, even when the missing information originated with a customer, agent or overseas supplier. Haulage businesses should therefore have a clear pre-departure check covering safety and security references, customs declarations, transit documents and any vehicle movement references required for the route.
For accompanied roll-on roll-off traffic, the party moving the tractor unit and trailer may need to provide or validate information before the crossing. For unaccompanied freight, responsibility can be divided between the trailer operator, ferry operator, forwarder and customs intermediary. The commercial contract matters, but it does not remove the need for a workable handover process.
Freight forwarders, customs agents and 3PLs
Forwarders, customs agents and 3PLs may submit safety and security declarations on behalf of the liable party. This is often the most practical arrangement where they already hold the shipment data and manage customs formalities.
Delegation should be specific. Agree who prepares the data, who submits it, who receives the acceptance or reference number, and who contacts the carrier if details change. A declaration lodged by an agent does not remove the need for the responsible party to ensure that the information supplied is correct.
ENS and EXS: which safety and security filing applies?
An ENS is an advance declaration for goods entering Great Britain. It contains security-related information that allows authorities to assess a consignment before it arrives. It is not a substitute for an import declaration to HMRC's Customs Declaration Service, and it does not calculate duty or VAT.
An EXS is the equivalent type of safety and security declaration for goods leaving Great Britain where the necessary information is not already contained in an export declaration. It is less visible in day-to-day operations because many standard export declarations include the required data, but it is relevant for exceptions and non-standard flows.
The key operational question is not simply, “Are we importing or exporting?” Ask instead: what customs declaration is being made, what transport is being used, and has the required safety and security data already been supplied through the correct channel?
This distinction matters for businesses moving goods between Great Britain, Northern Ireland and the Republic of Ireland. Northern Ireland follows different customs and safety and security arrangements because of its continued application of relevant EU rules. Direct movements involving Northern Ireland, Ireland and Great Britain must be assessed by route and procedure rather than treated as a single UK domestic movement.
Safety and security filing responsibilities by transport model
Responsibility becomes clearer when businesses map their own operating model. Four common scenarios illustrate the difference:
- A UK importer using a ferry operator and its own haulier: the carrier may lodge the ENS, but the importer and haulier must provide accurate goods and vehicle information early enough for submission.
- A freight forwarder arranging door-to-door transport: the forwarder may submit as the carrier's representative or manage the data collection, subject to the agreed authority and transport contract.
- An exporter making a standard GB export declaration: the export declaration may satisfy safety and security data requirements, provided it contains the necessary information for that movement.
- An unaccompanied trailer movement: the trailer operator, ferry operator, forwarder and customs agent need an agreed sequence for data submission, references and release to travel.
There is no benefit in treating responsibility as a legal technicality. The real test is whether the driver, trailer or container can proceed when it reaches the port gate.
What information is needed before the filing can be made?
Safety and security declarations rely on timely, consistent commercial data. The precise data set varies, but businesses should expect to provide details of the consignor and consignee, goods description, packages, commodity information where required, transport equipment, route, country information and the parties involved in the movement.
Descriptions deserve particular attention. “Parts”, “samples” or “general cargo” may be commercially familiar, but they may not provide enough meaningful information for a security declaration. Build better descriptions into order processing and booking workflows rather than asking a driver to resolve them at the port.
The filing must also meet the relevant pre-arrival or pre-departure deadline. These deadlines vary by mode of transport and journey type. A last-minute booking can therefore be a compliance problem, not merely an administrative inconvenience. If shipment data changes after filing - for example, a vehicle registration, trailer number or routing changes - check whether the declaration must be amended.
How to make safety and security compliance manageable
The most reliable approach is to make safety and security a defined stage of the transport process. It should sit alongside commercial invoicing, customs classification, export or import declarations, transit and port readiness - not be left until the vehicle is queued for a sailing.
Start by documenting each regular route. Record the origin and destination, transport mode, carrier, customs procedure, declaration owner, system used and the reference that confirms submission. This exposes gaps quickly, especially where more than one provider handles a movement.
Then decide whether your team has the capability to process declarations in-house. Businesses with stable volumes and trained staff may benefit from direct system connectivity and control over their data. Others may prefer an agency-managed service, particularly for occasional or complex movements. A hybrid model can work well too: routine flows are processed internally, while unusual routes and escalations are supported by customs specialists.
Custran supports both approaches through customs software, training, operational support and agency services. The aim is not to add another system for staff to manage. It is to give teams a clear, repeatable way to submit the right information to the relevant government and border systems.
When responsibilities are agreed before goods are collected, safety and security filings become a routine part of moving freight rather than a problem discovered at the terminal. That is the practical standard: every movement should have a named owner, accurate data and enough time to act before the border makes the decision for you.
