Key Takeaways
A Safety and Security Declaration is a mandatory pre-arrival notification required by UK customs law and EU regulation for most goods entering the UK or EU.
In the UK it is called an Entry Summary Declaration (ENS) and is submitted via HMRC’s Customs Declaration Service (CDS).
In the EU it is governed by the Import Control System 2 (ICS2), which reached its final phase in 2024.
Non-compliance can result in civil penalties of up to GBP 2,500 per declaration in the UK and refusal of entry for goods.
Customs software like iCustoms connects directly to HMRC CDS and automates the entire ENS filing process, eliminating manual errors.
If your goods are heading into the UK or European Union, chances are you need to file a Safety and Security Declaration before they even leave the port of loading. This is not optional paperwork. It is a legal requirement designed to give customs authorities the information they need to carry out risk assessments before goods arrive.
This guide covers everything you need to know: what a Safety and Security Declaration is, who is responsible for filing it, how to submit it through HMRC CDS or EU ICS2, the deadlines that apply to each transport mode, what happens if you miss them, which goods are exempt, and how customs software can automate the process from end to end.
What Is a Safety and Security Declaration?
A Safety and Security Declaration is a pre-arrival or pre-departure notification submitted to customs authorities containing information about incoming or outgoing goods. Its primary purpose is to enable customs agencies to perform risk analysis and identify potential security threats, smuggling, or prohibited goods before they physically enter or leave a country.
In the United Kingdom, the Safety and Security Declaration takes the form of the Entry Summary Declaration, commonly referred to as an ENS. It is submitted through HMRC’s Customs Declaration Service (CDS) and must be lodged within specific time windows before the goods arrive at a UK port or airport.
In the European Union, the equivalent obligation is governed by the Import Control System 2, known as ICS2. ICS2 replaced the original Import Control System (ICS1) in three phases between 2021 and 2024 and applies to all goods entering the EU customs territory.
Both the UK ENS and the EU ICS2 declaration require similar core data: the identity of the consignor and consignee, a description of the goods, the commodity code (HS code), the country of origin, packaging and container details, and the means of transport. Crucially, this information must be submitted before the goods depart, not on arrival.
HMRC Safety and Security Declaration: The UK Rules Post-Brexit
Since the UK left the EU’s customs territory at the end of 2020, the UK has operated its own Safety and Security regime, administered by HMRC. The legal basis is the Customs (Import Duty) (EU Exit) Regulations 2018, with detailed operational guidance published in HMRC Public Notice 760.
Under UK rules, an Entry Summary Declaration must be submitted to HMRC via the Customs Declaration Service before the goods arrive in Great Britain. The declaration is assigned a Movement Reference Number (MRN) upon successful submission. This MRN must be presented to the carrier and to border force at the point of entry.
HMRC uses the ENS data to carry out an automated risk assessment. If the system flags a consignment as high risk, HMRC may issue a ‘do not load’ instruction or place a hold on the goods upon arrival. Failing to submit an ENS, or submitting one with errors, can trigger penalties and delay your shipment significantly.
| Information about the goods | Description, commodity code, quantity, packaging, and value. |
|---|---|
| Details of the parties involved | Consignor, consignee, carrier, and agent. |
| Transportation information | Vessel, conveyance, container, or vehicle; route; mode of transport; and expected arrival date and time. |
| Identification numbers | EORI numbers of the carrier and relevant parties; IMO vessel number, flight number, or vehicle registration number; and transportation document number (e.g., bill of lading, air waybill, CMR waybill). |
| Location information | Relevant location code or port of entry code. |

Safety and Security Declarations for EU Imports: ICS2 Explained
For goods entering the European Union, the Import Control System 2 (ICS2) is the mandatory pre-arrival filing system. ICS2 is based on Article 127 of the Union Customs Code (Regulation (EU) No 952/2013) and introduced a significant shift in how safety and security data is collected and used.
Unlike the old ICS1 system, ICS2 operates on an ‘earliest possible’ data submission model, meaning that detailed goods information must be submitted as early as possible in the supply chain, often before the goods are even loaded. ICS2 also introduced a new data set called the Entry Summary Declaration (H7) for postal and express consignments.
ICS2 was rolled out in three releases: Release 1 (March 2021) covered postal operators and express couriers for air cargo. Release 2 (March 2023) extended to all remaining air cargo operators. Release 3 (March 2024) brought road, rail, and maritime operators into the new system. If your goods enter the EU by any means, you are now operating under ICS2.
Who Is Responsible for the Safety and Security Declaration?
Under both UK and EU law, the primary responsibility for submitting the Safety and Security Declaration rests with the carrier, meaning the person or company operating the means of transport that brings the goods into the customs territory. In practice, however, carriers frequently delegate this obligation to their authorised agents, customs brokers, or freight forwarders.
In the UK, under HMRC rules, if the carrier appoints a representative, that representative acts either as a direct representative (in the name of the carrier and on their behalf) or as an indirect representative (in their own name but on behalf of the carrier). The distinction matters because indirect representation makes the agent jointly liable for the declaration.
For importers who are arranging their own shipments, the filing obligation can fall to them if they are acting as the de facto carrier or have taken on that responsibility contractually. If you are using a freight forwarder or customs broker, it is worth confirming in writing who will be filing the ENS and ensuring their EORI number is authorised with HMRC.
How to Submit a Safety and Security Declaration: Step-by-Step
Submitting a Safety and Security Declaration manually through HMRC CDS involves several steps. Using compliant customs software significantly reduces the risk of errors and ensures your declaration is submitted within the required time windows.
- Register for HMRC CDS: You need an EORI (Economic Operators Registration and Identification) number and a CDS login. If you do not have these, you must register before you can file any declaration.
- Gather the required data elements: You will need the consignor and consignee EORI or name and address, a full description of the goods, the HS (commodity) code, country of origin, gross mass, number and type of packages, container number if applicable, and transport details including the means of transport and anticipated arrival time.
- Complete the ENS in CDS: Log into the Customs Declaration Service and complete the Entry Summary Declaration. The declaration type code for an ENS is ‘N’ followed by the procedure code. Ensure all mandatory data fields are populated correctly.
- Submit within the required timeframe: The ENS must be submitted before the goods depart. The specific deadline depends on the mode of transport (see the transport modes section below).
- Receive your MRN: Upon successful submission, HMRC issues a Movement Reference Number (MRN). This must be communicated to the carrier and used at the border.
- Respond to any HMRC queries: If HMRC’s risk assessment flags the consignment, you may receive a ‘do not load’ instruction or a query requesting additional information. Respond promptly to avoid delaying your shipment.

Safety and Security Declaration Timelines by Transport Mode
The time by which you must submit your ENS before goods arrive depends entirely on the mode of transport being used. Missing these deadlines is treated as non-submission and carries the same penalties. The table below shows the pre-arrival timeframes required under UK HMRC rules:
| Mode of Transport | ENS Submission Deadline | Notes |
|---|---|---|
| Deep-sea container shipping | 24 hours before loading at the port of departure | The longest lead time. Declaration must be lodged before goods are loaded onto the vessel. |
| Short-sea / RoRo shipping | 2 hours before arrival at the UK port | Applies to roll-on roll-off ferries. Shorter window due to faster transit times. |
| Air cargo (long haul) | 4 hours before arrival at the UK airport | Applies to long-haul air freight. Express courier shipments may have different deadlines under express carrier procedures. |
| Air cargo (short haul) | As early as practicable before departure, minimum at departure | Applies to short-haul flights (typically under 4 hours' flight time). |
| Rail freight | 2 hours before arrival at the first UK rail terminal | Applies to Eurotunnel and cross-Channel rail services. |
| Road freight | 1 hour before arrival at the UK border | The shortest window. Road hauliers and their agents must have systems in place for rapid filing. |
Goods Exempt from Safety and Security Declarations
Not all goods entering the UK require an ENS. HMRC has published a list of exemptions in Public Notice 760. The most common categories of exempt goods include:
- Goods brought into the UK from a country that has a security and safety agreement with the UK that provides for mutual recognition of pre-arrival controls
- Goods carried in baggage as personal effects by passengers travelling for non-commercial purposes
- Goods in postal consignments with a value below GBP 135 that are not subject to prohibitions or restrictions (noting that express courier shipments have separate rules)
- Military goods and goods for the use of armed forces travelling under military transport arrangements
- Goods covered by diplomatic bags under the Vienna Convention
- Goods for temporary storage not exceeding 45 days at an approved temporary storage facility
- Goods moving between the UK and the Channel Islands or the Isle of Man under specific arrangements
If you are unsure whether your goods qualify for an exemption, seek advice from a qualified customs agent or contact HMRC directly. Incorrectly claiming an exemption and not filing an ENS is treated as non-compliance.
Penalties for Non-Compliance with Safety and Security Declaration Requirements
Failure to comply with Safety and Security Declaration requirements is taken seriously by HMRC. The penalties are set out under Schedule 41 of the Finance Act 2008 and can be applied in any of the following circumstances:
- Failure to submit an ENS at all: HMRC can issue a civil penalty of up to GBP 2,500 per declaration. Repeat non-compliance can lead to higher penalties and referral to HMRC’s criminal investigation unit.
- Submission after the deadline: Even if an ENS is eventually submitted, submitting after the required pre-arrival deadline is treated as late submission and can result in a reduced penalty of GBP 500, rising on a sliding scale for persistent lateness.
- Submission with inaccurate or missing data: An ENS submitted with material inaccuracies, such as an incorrect HS code, wrong consignee details, or a missing container number, can result in a penalty of up to GBP 2,500. HMRC’s risk system may also place a hold on the goods pending clarification.
- Goods held at the border: Beyond financial penalties, the practical consequence of non-compliance is that HMRC or Border Force may refuse entry to the goods, or place them in temporary storage at the importer’s cost. Storage charges at major UK ports can run to several hundred pounds per day.
Commercial Reality
A single rejected or late ENS can cost far more than the GBP 2,500 maximum penalty when you factor in storage charges, missed delivery windows, and the cost of your team’s time spent dealing with HMRC queries. Automated customs software that validates ENS data before submission is the most cost-effective compliance investment available.
GVMS and Safety and Security Declarations: How They Connect
The Goods Vehicle Movement Service (GVMS) is HMRC’s pre-lodgement model that links multiple customs declarations to a single vehicle movement at UK ports. Understanding how GVMS interacts with Safety and Security Declarations is essential for road hauliers, ferry operators, and Eurotunnel users.
Under GVMS, the driver or carrier creates a Goods Movement Reference (GMR) before arriving at the port. The GMR collects the MRNs from all relevant declarations associated with that vehicle movement, including the ENS (if required), import declarations (if applicable), and transit declarations. All declarations must be pre-lodged and their MRNs added to the GMR before the vehicle can board the ferry or enter the Eurotunnel terminal.
For road freight arriving in Great Britain, the ENS MRN must be included in the GMR. Carriers who arrive without a valid GMR that includes all required declaration MRNs will be refused boarding. This is the most common cause of freight delays at Dover, Holyhead, and other GVMS-enabled ports.
GVMS applies at all designated inventory-linked ports in Great Britain. Check the HMRC list of GVMS-eligible locations when planning freight movements, as the requirement to use GVMS varies by port and by the type of goods movement.
Exit Summary Declaration (EXS): What Exporters Need to Know
A Safety and Security obligation exists not just for imports but also for exports leaving the UK. The Exit Summary Declaration, known as an EXS, must be submitted when goods leave the UK’s customs territory by road or rail, or when goods are exported from the EU and there is no export declaration covering the safety and security data.
The EXS is submitted after the export declaration has been accepted and before the goods physically leave the UK. It confirms the safety and security data for the exiting goods and allows customs authorities to conduct exit risk analysis. Like the ENS, the EXS is submitted via HMRC CDS and generates an MRN.
In many export movements, the data required for an EXS is already captured within the export declaration itself. In these cases, a separate EXS is not required. However, for goods moving under transit procedures or where the export declaration does not cover all required safety and security fields, a standalone EXS is necessary.
T1 Transit Forms and the Transit Accompanying Document (TAD)
When goods move through multiple customs territories without entering free circulation, they travel under a transit procedure. The most common transit procedure used for UK and EU movements is the Common Transit Convention (CTC), which uses the New Computerised Transit System (NCTS) for electronic declaration processing.
A T1 form is the transit declaration for goods that have not been cleared through customs and are therefore moving as ‘non-union goods’ (in EU terminology) or ‘non-UK duty-paid goods’ through the customs territory. The T1 declaration is submitted electronically via NCTS and generates a Movement Reference Number.
The Transit Accompanying Document (TAD) is the physical printout or electronic representation of the NCTS transit declaration that accompanies the goods during their journey. The TAD contains the MRN, a barcode, and the key details of the transit movement. It must be presented to customs at the office of transit and the office of destination.
For safety and security purposes, goods moving under a T1 transit procedure do not require a separate ENS in most cases because the transit declaration itself covers the safety and security data. However, the interaction between transit procedures, ENS obligations, and GVMS requirements can be complex, particularly for movements that combine transit and import procedures at the same border crossing.
