Introduction
This guide explains how to prepare and submit a standalone Simplified Frontier Declaration in the Trader Support Service (TSS) Portal using the TSS Simplified Procedure.
The Simplified Frontier Declaration is part of the customs declarations on the TSS Simplified Procedure. A Simplified Frontier Declaration, usually auto-generated by TSS from the information provided in the Entry Summary Declaration, is made before the goods movement using a simplified data set.
It is the responsibility of the Importer of Record to ensure the Simplified Frontier Declaration is completed.
Note: Traders moving ‘not at risk’ goods only from GB to NI may be able to utilise the simplified processes for Internal Market Movements. To benefit from the simplified processes, traders need to be authorised under the UK Internal Market Scheme (UKIMS). For further guidance on UKIMS authorisation and how to apply, refer to GOV.UK. Information on the simplified processes and available journey options can be found in the Simplified processes for Internal Market Movements – Introduction Guide and the Internal Market Movement page on NICTA.
What is a standalone Simplified Frontier Declaration?
While Simplified Frontier Declarations are typically automatically generated from an Entry Summary Declaration, you can also create a standalone Simplified Frontier Declaration, provided criteria are met, which is not generated automatically from a previously submitted Entry Summary Declaration.
The standalone Simplified Frontier Declaration process should only be used when:
- Using certain special procedures or relief options on the TSS Simplified Procedure. Further details can be found in the Special procedures and relief options on the TSS Simplified Procedure section of this guide
- The haulier/carrier has completed the Entry Summary Declaration outside of TSS and you wish to complete the customs declarations in TSS
- The haulier/carrier has created an Entry Summary Declaration only movement in TSS and you wish to complete the customs declarations on TSS
Note: Should you wish to create a Simplified Frontier Declaration from an ‘Entry Summary Declaration only’ movement, you may use the Create SFD from ENS functionality if the movement:
- Has a reason for submitting only an Entry Summary Declaration selected on it
- Was raised in TSS
AND
- Is in ‘Authorised for Movement’ status
In all cases, an Entry Summary Declaration must still be completed either in or outside of TSS prior to goods movement.
Note: TSS supports standalone Simplified Frontier Declarations for Roll on Roll off (RoRo) movements only. It does not support standalone Simplified Frontier Declarations for maritime or air movements, regardless of whether they are Inventory-Linked Ports or locations in NI.
The TSS Simplified Procedure
The TSS Simplified Procedure allows businesses to move goods from Great Britain (GB) into Northern Ireland (NI) by making a simplified declaration before the goods move (pre-movement) and then providing the full information about the goods after they have moved (post-movement) for both ‘not at risk’ and ‘at risk’ goods. Further guidance on ‘not at risk’ and ‘at risk’ goods can be found on GOV.UK.
The TSS Simplified Procedure requires:
- A safety and security declaration, known as the Entry Summary Declaration, which must be done prior to the goods entering NI (usually completed by the carrier) AND
- The customs declarations, which are divided into multiple steps:
- A Simplified Frontier Declaration, usually auto-generated by TSS from the information provided in the Entry Summary Declaration, made before the goods movement using a simplified data set
Note: This guide covers how to complete a standalone Simplified Frontier Declaration in TSS as part of the TSS Simplified Procedure.
- A Supplementary Declaration, requiring a full data set which is always completed after the goods move and used to close the customs journey and pay any required duties and other charges
- If you qualify for the simplified processes, TSS has added functionality allowing traders who use the TSS Simplified Procedure to convert the generated Supplementary Declaration to an Internal Market Movement Information (IMMI). No duties are payable on the Internal Market Movement Information (IMMI).
- You must continue submitting a Supplementary Declaration, if the goods are not eligible for the simplified processes.
- Submission of the Supplementary Declaration is required by the tenth calendar day of the month following the goods movement.
- Submission of the Supplementary Declaration is the responsibility of the Importer of Record, as indicated by the Importer EORI on the TSS Simplified Frontier Declaration.
- A Final Supplementary Declaration, detailing the number of Supplementary Declarations finalised for a reporting period (arrivals with a tax point date in the previous calendar month) compared to the Supplementary Declarations due, which TSS will automatically submit on your behalf
Special procedures and relief options on the TSS Simplified Procedure
Traders with their own Simplified Customs Declaration Procedure (SCDP), formerly known as the Customs Freight Simplified Procedure (CFSP), authorisations that are using certain special procedures are allowed to use the TSS Simplified Procedure for goods movements from GB to NI (including movements of non-domestic goods from a GB customs warehouse). You can process a standalone Simplified Frontier Declaration on TSS to support these movements.
For more information on special procedures, relief options and the requirements for having your own NI-valid SCDP authorisation to use special procedures on the TSS Simplified Procedure, refer to the Reliefs and Duty Suspension: Overview and considerations for data input in TSS declarations guide on NICTA.
For information on SCDP authorisations and how to add this information to your TSS Company Profile, see the Registration: Step-by-step guide to using TSS on NICTA.
How to create a standalone Simplified Frontier Declaration
TSS supports a functionality that allows you to create a standalone Simplified Frontier Declaration that is not automatically created from an Entry Summary Declaration submitted through the TSS Portal (for example, where the Entry Summary Declaration has been created elsewhere or where the haulier has created an Entry Summary Declaration only movement).
You can complete a standalone Simplified Frontier Declaration using either the TSS SCDP authorisation or your SCDP authorisation.
If you prefer to use your own SCDP authorisation, you also have the option to select if the Supplementary Declaration will be generated in TSS. A Supplementary Declaration is required to complete your customs journey. TSS will give you the option to either complete the Supplementary Declaration on TSS with information auto-populated from your Simplified Frontier Declaration or complete the Supplementary Declaration outside of TSS.
If you prefer to use TSS SCDP authorisation on the standalone Simplified Frontier Declaration, TSS will generate a Supplementary Declaration in TSS for you to complete as part of the TSS Simplified Procedure customs declaration process.
Depending on the SCDP authorisation used on your Simplified Frontier Declaration, you will be shown a drop-down list of the Declaration Categories that are allowed under the selected SCDP authorisation, including those used for customs special procedures and duty relief.
With either option, submission of the Supplementary Declaration in TSS is required by the tenth calendar day of the month following the goods movement.
To create a standalone Simplified Frontier Declaration in the TSS Portal follow these steps:
- Select Start a Goods Movement from the banner at the top of the page, under Goods Movements
- Then, within the Additional Goods Movement Options, select Start a Simplified Frontier Declaration (SFD) / Entry In Declarants Record (EIDR). This will open a new record.
- A form will open showing the name of the Submitter in the first field
- Select the Movement Type: either ‘Pre-lodged (IMF)’ for shipments that have not yet moved, or ‘Arrived (IMC)’ for shipments that have already moved
- For the Type of Movement field, select ‘RoRo’ (Accompanied / Unaccompanied)’
- In the Identity Number of Transport field:
- For accompanied Roll on Roll off (RoRo) add the haulier’s vehicle registration
- For unaccompanied RoRo only the trailer number is required
Note: this field is 27 characters in length.
- In the Nationality of Means of Transport field, select the country where the vehicle is registered (for example, ‘United Kingdom’) from the drop-down list
- Complete the Carrier EORI number
This must be a XI EORI number. The carrier is the operator of the active means of transport at the border.
- Add the Arrival Date/Time when the shipment is expected to land in NI
Note: this field is not visible if the Declaration Category is ‘Arrived (IMC)’.
- Select the Port of Arrival from the drop-down list by either typing in the field or using the selection – this is the first seaport or airport where the goods enter NI
- Where seals are affixed to the transport equipment, the identification number on the seal must be added to the Seal Number field; otherwise, leave this field blank
- The Route will default to ‘GB-NI’
- In the Place(s) of Loading free-text field, add the place(s) of loading of the goods; for example, the freight terminal or other place where the goods were loaded onto the means of transport
For accompanied RoRo movements, the place of loading is where the goods are loaded onto the truck (for example, ‘Liverpool’).
If there are multiple places of loading for a RoRo movement (groupage), enter the best indication of the primary locations, in up to 35 characters (for example, ‘Edinburgh, Glasgow’).
- Add the Place(s) of Unloading
This is the name(s) of the freight terminal or other place where goods are unloaded from the means of transport. For accompanied RoRo movements, the place of unloading is where the goods are unloaded from the truck (for exampel, ‘Belfast’).
If there are multiple places of unloading for a RoRo movement (groupage), enter the best indication of the primary locations, in up to 35 characters (for example, ‘Belfast’, ‘Larne’).
- In the Transport Charges field, from the drop-down list, select the option that indicates how the respective charges will be paid
This is the method of payment (from the trader to the carrier) for transporting the goods. The field defaults to ‘Account Holder with Carrier’, though you can opt for whichever suits the movement.
How to save the standalone Simplified Frontier Declaration
- You can save the form any time by pressing the Save as Draft button on the bottom right of the page. If (before adding the consignment details) you need assistance completing this part of the form, press the Get Help
- Once saved, you will be presented with the following details, including the unique Simplified Frontier Declaration Reference Number at the top of the page. This will take you through to the Consignments part of the declaration.
- Find your current Simplified Frontier Declaration movement information by selecting Goods Movements in the banner of the TSS Portal followed by View a Goods Movement and clicking on SFD Declarations (by movement). A new tab will open that will allow searching and viewing SFD Declarations (by movement) by Status.
How to create a standalone Simplified Frontier Declaration consignment
You must add at least one consignment to each standalone Simplified Frontier Declaration header (each movement). A consignment is a set of goods being moved from one consignor (seller/sender) to one consignee (buyer/receiver).
TSS will generate one standalone Simplified Frontier Declaration for each consignment.
- When the standalone Simplified Frontier Declaration is saved at the movement level (as shown in the How to save the standalone Simplified Frontier Declaration section of this guide), scroll down to the Consignment Information tab and click the New button
Alternatively, you can select the Create Consignments button from the movement page instead of the Save as Draft button.
The top section of the consignment page provides key information, depending on the status of the declaration. The fields highlighted in grey are read-only fields, including the Status.
- The Transport Information section is auto-populated from the standalone Simplified Frontier Declaration header
- Navigate to the bottom of the page and click on the New button on the Consignment Information tab
- Having selected the option to create a new consignment, you will be directed to a new form labelled Consignment Information – new record page
The top section provides key information, depending on the status of the declaration. The fields highlighted in grey are read-only fields, including the Status.
- If you select ‘Yes’ to the the field Does Consignment contain goods subject to control, licence or certification? additional fields are added to the consignment and the item level to support additional data required for controlled goods
Further guidance and information on controlled goods can be found in Guidance on controlled goods and the Online Tariff Tool on NICTA.
- The Goods Information section has three sections greyed out that are read only
The Total Packages and Total Gross Mass (KG) fields will be populated from the item level, and the Transport Document Type field will default to ‘CMR/Delivery Note’, which is the document used for RoRo and road journeys. (You will have selected ‘RoRo’ within the Type of Movement field at the consignment (header) level.
- Add the Transport Document Number, which is the identification number of the ‘CMR/Delivery Note’. Note: this field is limited to 35 characters.
- The Goods Domestic Status field defaults to ‘NIDOM (UK domestic status goods)’, but the drop-down list has an option to select ‘NIIMP (Non-UK domestic status goods)’
- Destination Country will default to ‘United Kingdom’ for NI
If onward supply relief (OSR) procedure is being used the destination code should not be GB or IM; the country of destination must be a European Union (EU) member state (for example, ‘Ireland’).
- Complete the Consignment Description field for the associated goods in this consignment
This should be a plain language description of the goods that is precise enough for customs to be able to identify what the goods are. The description should cover:
- What are the goods?
- What are they made of?
- What are they used for?
If the package contains any branded items, it’s advisable to include the brand and model number along with the description. It’s also recommended that the descriptions are packaged as sets and sizes (for example, ‘women’s cotton T-shirts, size 14, packs of 3’).
For guidance on what an acceptable goods description should contain including examples, see the Goods Description guide on NICTA.
- You can choose to populate the Trader Reference field
This is a free-text field for personal reference only (for example, if you want to list an invoice number with your consignment or a collection point) and will not affect whether your standalone Simplified Frontier Declaration can be completed.
- The Declaration Unique Consignment Reference (DUCR) field is used to link the Entry Summary Declaration, standalone Simplified Frontier Declaration and the Supplementary Declaration
You may complete the DUCR data field with your internal company nomenclature following the recommended format detailed in References of Messages, Document, Certificates and Authorisations for Imports on GOV.UK. Alternatively, on the standalone Simplified Frontier Declaration the DUCR field will be auto-populated by TSS.
- Add the EORI numbers for the Consignor, Consignee, Importer, Importer Parent Organisation (where required) and Exporter
If the EORI number is unknown for the Consignor, Consignee, or Exporter, select the check box and complete the additional fields.
Note: If the EORI number is invalid it will be cleared from the field.
For the Consignor and Consignee, Importer, Importer Parent Organisation EORI and Exporter the EORI field may have a prefix of ‘GB’ or ‘XI’
Note:
- If, at this point, you wish to use NIREM to claim the ‘not at risk’ benefit on the Supplementary Declaration, the Importer EORI number will need to be aligned to a valid UKIMS Authorisation
If there is a mismatch of EORI references, the Customs Declaration System (CDS) system will fail to apply any relevant exemptions.
- If a GB EORI has been entered in the Importer EORI field, CDS will mandate the name and address of the GB EORI holder
In the Company Profile, if you have chosen to keep your company name private, you will need to manually enter the company name and address in the respective fields marked with a red asterisk. However, if you have chosen not to keep your company name private, TSS will auto-populate the name and address in the appropriate fields for you.
- Importer Parent Organisation EORI is an optional field for cases where a child company is a using parent company’s DDA for the deferment of duty, import VAT, excise and other charges
- The field is visible only if Do you need to use a Parent Organisation Authorisation on your declarations is answered with ‘Yes’ on the Company Profile
In these cases, the Importer Parent Organisation EORI field is either auto-populated with the relevant parent company EORI number or is blank and editable depending on the Company Profile set up.
- If the question Do you need to use a Parent Organisation Authorisation on your declarations is answered with ‘No’ on the Company Profile, the Importer Parent Organisation EORI field is not visible or available for input on the standalone Simplified Frontier Declaration
Should you wish to use the DDA of your parent company to defer customs charges, review the Do you need to use a Parent Organisation Authorisation on your declarations field in your Company Profile and make the respective changes. For details on how to do so see the Registration: Step-by-step guide using TSS on NICTA.
Note: The functionality for you to have visibility, authorise and manage related parties (for example, Carrier, Haulier, Entry Summary Declaration Submitter and Exporter) on your declarations is in the ‘Related Parties’ section of the Company Profile.
- Once the details are added, press the Save (Ctrl + s) button and the unique DEC_____________ reference number for the consignment will be presented at the top of the page
- A new field will appear next to the Importer EORI field for you to select if you would like to use your own SCDP authorisation
Note: This field is only visible where you have an SCDP authorisation listed on your Company Profile. If you do not have one listed, proceed to the Representation Type step.
If selecting ‘Yes’, a pop-up message will appear to confirm the SCDP authorisation number that has been added to your TSS Company Profile, which will be used to support the consignment: ‘As the authorisation holder, I am granting TSS permission to use my XI EORI and CFSP authorisation number in order to progress my declaration using the TSS portal’
Note: If you are using your own SCDP Authorisation, this authorisation must be applicable to Northern Ireland movements and have an ‘XI’ prefix.
- Select an option from the drop-down field Which type of declaration do you intend to make? based on the procedure code used on the declaration
For guidance on end-use, inward processing and customs warehouse requirements, refer to the Reliefs and Duty Suspension: Overview and considerations for data input in TSS declarations guide on NICTA for the Procedure Codes and Additional Procedure Codes that are available.
- The field If a Supplementary Declaration is required, do you wish to complete that in TSS? will either auto-populate and be read only or give you an option to confirm that you want a Supplementary Declaration to be generated for you in the TSS Portal where one is required.
Note: Where ‘Declaration for customs warehousing (71XX)’ is selected, the TSS system will advise that a Supplementary Declaration is not required and will auto-populate this field to ‘No’ and read only.
- The Representation Type field will be auto-populated with ‘Direct’
- The Header Previous Document field will auto-populate with the DUCR number
To add more previous documents, select New button on the tab and enter the required details.
- The Holder of Authorisation tab will auto-populate with the Authorisation Type Code ‘SDE’
If the intended movement involves a customs relief or special procedure, you can find further information about them in the Reliefs and Duty Suspension: Overview and considerations for data input in TSS declarations guide on NICTA for the respective document references and authorisations required in the declaration.
Add authorisation records by selecting the New button on the tab and entering the required details.
The field Authorisation Role Type is auto-populated by TSS. You do not need to populate this.
Once all the details are added, press Save (Ctrl + s).
- Before completing data entry for a consignment, it is recommended that you attach any relevant documents relating to your movement
If you do not, and your movement needs additional controls/inspections, you may be asked to upload these documents or physically present them during the movement of the goods. This could cause unnecessary delays to your journey.
There is a list below of the documents commonly required, refer to the Northern Ireland Online Tariff on GOV.UK for a definitive list of the documents required for a specific commodity code. For guidance on how to navigate the tariff tool, refer to the Guidance on controlled goods and the Online Tariff Tool on NICTA.
- Commercial invoice
- Packing list of items included
- Any non-electronic, paper licences
- Any certificates of origin
- Additional certificates, licences and permits for example, CITES permits
- Export Health Certificates (EHCs)
- Any further documents you may have referenced in the supplementary tabs at the bottom of the consignment or item page
Licences and certificates for controlled goods being moved from GB to NI may be subject to format, validity and content checks. It is the trader’s responsibility to ensure that all details on documents match the information that has been input into TSS. More information about document requirements can be found on Guidance on controlled goods and the online tariff tool on NICTA and on Moving licensed goods into or out of Northern Ireland on GOV.UK.
To attach documents, click on the paperclip icon at the top of the consignment or item page.
If the document applies to every item in the consignment, attach it on the consignment page using the paperclip icon.
If the document applies to an individual item, attach it on the item page using the paperclip icon. Next section details how to add items to a consignment.
Note: Any organisation that the consignment is shared with (for example, carrier/haulier) will be able to access uploaded documents.
Add items to a consignment
As mentioned above, you will need to add declaration goods (items) to each consignment. Each declaration goods item is a set of goods with the same description (with the same commodity code). For example, five pallets of a single type of apples should be added as one goods item on the declaration.
- Once the consignment has been saved, select the New button in the Goods Records section at the bottom of the consignment form
The Goods Records form will open denoted with a Declaration Reference at the top of the page.
Note: The maximum number of item(s) (sets of goods with the same description) that can be linked to a consignment is 99.
- Add the Package Marks; where containerised, the Equipment Number (if Containerised) field can be used as a shipping mark
- Add the Type of Packages from the drop-down list
- Add the Equipment Number (if Containerised) for the container, where goods are being shipped in a container; If not packaged in a container, leave the field blank
- Add the Number of Packages and then confirm the Number of Individual Pieces within each package (only relevant if not in bulk, as explained below)
For goods with documentation that has been entered into TRACES NT the Number of Packages must match what was inputted.
The Number of Packages is the number of individual items packaged in such a way that they cannot be divided without undoing the packing if not in bulk, and the Number of Individual Pieces if in bulk. For example, for palletised goods the number of pallets should be provided if the goods are covered/wrapped on pallets.
- Declare the UN Dangerous Goods Code, if applicable to your goods
This is a unique serial number assigned by the UN to dangerous substances and articles (for example, chemicals, weapons). The codes are available on the United Nations Economic Commission for Europe (UNECE) website; refer to the UN Recommendations on the Transport of Dangerous Goods – Model Regulations for details.
- Add the associated Invoice Number, where known
- Confirm the Item Gross Mass (weight) in kilograms for all packages – this needs to include all packaging (but not the carrier’s equipment)
- The Net Mass is mandatory for goods subject to control, licence or certification and optional for standard goods. It should be entered in kilograms and excludes packaging.
Note: Packaging is defined as materials and components used in any packaging operation to wrap, contain or protect the goods during transport.
- Add the Goods Description for these packages
This should be a plain language description of the goods that is precise enough for customs to be able to identify what the goods are. The description should cover:
- What are the goods?
- What are they made of?
- What are they used for?
If the package contains any branded items, it is advisable to include the brand and model number along with the description. It is also recommended that the descriptions are packaged as sets and sizes, for example, ‘women’s cotton T-shirts, size 14, packs of 3’.
For guidance on what an acceptable goods description should contain including examples, see the Goods Description guide on NICTA.
- Add the Procedure Code
Where items are released into free circulation, with no previous procedure in GB, this will be ‘4000’.
Completion notes for procedure codes can be found in Requested and Previous Procedure Codes for Imports on GOV.UK.
- Additional Procedure Codes specify where the importer has customs requirements above and beyond the standard procedure, for example when using a special procedure
A full list of Additional Procedure Codes that could apply can be found in the CDS guidance Additional Procedure Codes for Imports: Introduction and index list on GOV.UK. Only in cases where no other additional procedures apply should ‘000’ may be used (indicating no additional procedure to declare).
If the intended movement involves a customs relief or special procedure, refer to the Reliefs and Duty Suspension: Overview and considerations for data input in TSS declarations guide on NICTA to be aware of the respective Procedure Codes and Additional Procedure Codes required on the declaration.
- If you are moving controlled goods, update the following fields on the consignment items. The fields listed below are mandatory when the goods are controlled and thus required to meet additional control measures (for example, a certification, authorisation or licence)
If you are completing a standalone Simplified Frontier Declaration, you will need to input the following data:
- Commodity Code
- Supplementary Units
- CUS Code
- TARIC Additional Code
- National Additional Code
- Country of Origin
- Item Currency
- Item Price / Amount
- Tax Type
- Tax Base Unit
- Tax Base Quantity
You can find more information about these fields in the Data guide: TSS declaration data requirements on NICTA.
- After pressing Save, the following tabs will appear at the bottom of the screen:
Detail Previous Document
- Additional Information
- Document Reference
- Tax Bases
- Additional Procedure
- National Additional Codes
- If you have declared a special procedure code, you will need to complete the Additional Information and Document Reference tabs, as per the requirements of the particular special procedure
Refer to the Reliefs and Duty Suspension: Overview and considerations for data input in TSS declarations guide on NICTA for more information on Additional Information and Document References required for your declaration.
- When all the details have been added, press Save again
Once saved, the name of the goods is displayed at the top of the page, and you can navigate back to the consignment by clicking on the declaration’s LRN number.
- If you wish to add more Goods Records to your consignment, use the Save and Add New button to open a new record
The system will save the current goods record and automatically open a new Goods Record for you to complete.
If you wish to remove an existing goods record from the consignment you may do so by selecting the Delete Item Button
- Once all the consignments are added to the standalone Simplified Frontier Declaration movement and the consignment (header) level details have been checked for accuracy, press the Submit button
- Once the standalone Simplified Frontier Declaration has been approved, the Status field will change to ‘Authorised for Movement’
If you need to amend, download data or get a copy of your Simplified Frontier Declaration, refer to the How to use the TSS Portal guide on NICTA.
How to cancel a standalone Simplified Frontier Declaration
If you have raised a standalone Simplified Frontier Declaration in error, you can cancel the movement declaration, provided that the declaration is in the following state:
- Draft
- Does not have an Entry Summary Declaration (ENS) associated to it
- Does not have any consignments associated to it
Note: If you have added a consignment to the declaration movement, you must cancel this consignment first by navigating to the consignment and clicking on the Cancel Consignment button
The standalone Simplified Frontier Declaration can be cancelled by following these steps:
- Navigate to the declaration you wish to cancel by following the steps shown in the How to save the standalone Simplified Frontier Declaration section of this guide
- Click the Cancel SFD button
- Once successfully cancelled, the Status of the Simplified Frontier Declaration will change to Cancelled
