Simplified Frontier Declaration UK (SFD) — what data you must supply at the start

What a UK Simplified Frontier Declaration is — the one-paragraph answer

A UK Simplified Frontier Declaration (SFD) is a shortened customs declaration lodged with CDS at the moment the goods arrive at the UK border, as part of the CFSP/SCDP procedure. Instead of more than 70 fields of data, it requires a list of 12–15 data elements — enough for HMRC to release the goods from the border, but not enough to close the duty and VAT settlement. The financial settlement takes place later, in the Supplementary Declaration lodged by the 10th day of the month after import. The SFD is therefore an "entry ticket", not the final declaration — and that distinction must be clear before the first clearance, because the whole logic of risk and time savings hinges on it.

The EasyClearance Team serves clients with SCDP authorisation and those still applying for CFSP. This article is the operational counterpart to our CFSP pillar — that piece covers when and why to enter the simplified procedure; here we focus solely on what must go into the SFD.

SFD vs full declaration — comparing the data ranges

The difference in scale is large. A full CDS import declaration built to the UK Trade Tariff Volume 3 for CDS requires more than 70 data elements: the full 10-digit commodity code, the precise customs value with freight, insurance and commissions, a detailed preferential country of origin, document codes (invoices, certificates, EUR.1), Incoterms delivery codes, container numbers, and a full packaging specification. Every one of those fields is validated by CDS and any inconsistency blocks the declaration.

The SFD — per the CDS completion requirements for SCDP — requires 12 mandatory and up to 3 conditional fields. No precise value, no full HS, no document codes — all of these only land in the Supplementary. Thanks to this, the SFD can be sent at a moment when the importer only has the basic shipment data from the supplier, without waiting for the freight forwarder's final invoice.

The 12 mandatory SFD fields — operational list

Below is the precise data set you must have ready before sending the SFD to CDS. The list follows the official HMRC requirements for SCDP. The EasyClearance Team uses it as a checklist before every submission.

These 12 fields are the technical minimum. Without any one of them, CDS will reject the SFD and the goods will not be released from the border. Each field is subject to formal validation — the EORI must be registered, the location code must exist in the CDS dictionary, the HS code must be a valid 4-digit chapter.

Conditional fields — 3 extra data items in 30% of shipments

Besides the 12 mandatory fields, CDS may require further information if the goods are subject to sector-specific regulation. The most common scenarios, per the HMRC SDP guidance:

• Licence / permit number — for dual-use goods, weapons, explosives, or goods subject to sanctions. State the number and issuing authority.
• Surveillance code — for goods groups under HMRC monitoring (e.g. steel, certain chemicals). CDS requires a code from the surveillance list.
• Prohibition and restriction marker — for goods covered by the BTOM (products of animal origin, plants, high-risk food). Enter the notification code from the relevant sanitary/phytosanitary system.

In practice the EasyClearance Team sees that 30–40% of shipments handled under the SFD require at least one conditional field, so the real-world "minimum" is 13–15 data elements rather than 12.

How an SFD works in practice — step by step

The procedure from the moment you know the goods are on their way to the moment of entry to UK territory:

1. Confirm SCDP authorisation. The importer (or the customs agent acting for it) must hold a valid Simplified Customs Declaration Process authorisation. Without it the SFD is not available. HMRC typically takes 60–120 days to decide.
2. Gather the 12 + conditional fields. The importer supplies the supplier data (goods description, country, value range, weight); the customs agent adds the EORI, representation type, location code and procedure code.
3. Send the SFD to CDS. The declaration goes to CDS before the goods arrive (pre-arrival) or at the moment they reach the frontier (on-arrival). The submission type depends on the importer's operating model.
4. Acceptance and SFD MRN. CDS validates and returns the SFD MRN. The number goes into the GMR in GVMS, the driver crosses the border and the goods move to the consignee.
5. Supplementary Declaration (SDP). No later than the 10th day of the month following import, the importer lodges the SDP with the full data set and the VAT/duty settlement. Only then does money move from the Duty Deferment Account.
6. 6-year archiving. SFD, SDP, invoices, value evidence and licences — all retained for 6 years for HMRC audit.

The 5 most common SFD pitfalls — EasyClearance Team observations

From daily work with SCDP clients we see recurring errors that either block the SFD at the border or create problems in the Supplementary:

1. Goods description (field 6) too general. "Commercial goods" is not enough — CDS will reject it. The description must let HMRC allocate the goods to a Tariff chapter.
2. Mistake in the frontier location code (field 5). Dover is GBAUDVRDVRDVR, Holyhead is GBAUHHDHHDHHD — entering "Dover" as free text rejects the declaration. The code list is in the HMRC guidance.
3. Value range too narrow or too wide. A 0–10 £ range for a 45 £ invoice = inconsistency at the SDP. A range of "0–1,000,000" also triggers compliance flags — HMRC expects a reasonable estimate.
4. Country of origin code that doesn't match the SDP. The SFD says "CN" while the Supplementary turns out to show "VN" — retrospective change can break tariff preferences and trigger an audit.
5. Missing ENS↔SFD synchronisation. The ENS MRN (field 4) must be valid and open at the moment of the SFD. If the carrier lodged the ENS with an error, the SFD will also be rejected.

The EasyClearance Team resolves each of these errors before submission, but this requires discipline when collecting data from the importer. That is why we keep a standing checklist template for SCDP clients.

Who can lodge an SFD — authorisation limits

The SFD is not an open route for every importer. To use it you must meet these conditions:

• SCDP authorisation granted by HMRC after a CFSP1 application. Requires 3 years of VAT/customs compliance history, internal procedures and a risk assessment.
• Duty Deferment Account (DDA) or Cash Deposit Account for monthly duty/VAT settlement.
• Access to CDS — directly or through a customs agent.
• GB EORI number (XI for Northern Ireland).

A customs agent can lodge the SFD on a client's behalf under direct or indirect representation. Under indirect representation the agent becomes jointly liable for customs obligations — a choice that changes the risk profile. The EasyClearance Team prefers direct representation for clients with established compliance and indirect for new importers with no SCDP history.

What follows from the current official rules

The UK Simplified Frontier Declaration (SFD) is a shortened customs declaration under SCDP requiring 12 mandatory and up to 3 conditional data elements — about 15 fields in total rather than 70+ in a full CDS declaration. It contains the EORI, ENS MRN, location, simplified description, 4-digit HS, value range, country of origin, weight, number of packages and procedure code. It releases goods from the border within minutes, but does not close the settlement — the Supplementary Declaration with the full data set is lodged by the 10th day of the month after import. Errors in the SFD (description too general, wrong location code, desynchronised value range, mismatched country of origin, disjointed ENS↔SFD) block entry and create the risk of retrospective corrections. The SFD is available only to businesses with SCDP authorisation, a DDA and access to CDS. This article reflects the position as at 2026-04-19 and does not replace consultation with a customs agent.

FAQ — frequently asked questions

How does a Simplified Frontier Declaration (SFD) differ from a standard customs declaration in the UK?

An SFD requires 12–15 data elements (EORI, MRN of the safety declaration, location, simplified 4-digit HS code, value range, simplified country of origin, goods description, declarant). A full CDS declaration requires more than 70 data elements per the UK Trade Tariff. The SFD releases goods from the border within minutes; the full duty/VAT reckoning is completed later, in the supplementary declaration, with a deadline of the 10th day of the month after import.

Who can lodge a Simplified Frontier Declaration in the UK?

Only an importer with a valid Simplified Customs Declaration Process (SCDP) authorisation, or a customs agent acting under the client's authorisation with its own Duty Deferment Account or CDCA, can lodge an SFD. It is not possible to lodge an SFD ad hoc without HMRC authorisation — it is part of a simplified procedure, not a separate frontier route. The EasyClearance Team serves clients who already hold SCDP authorisation and those applying for it.

What is the minimum data required in a UK SFD?

The operational minimum is 12 data elements: importer's EORI number, declarant's EORI, ENS MRN, goods location, simplified goods description, simplified 4-digit HS code (not the full 10-digit one), value range, simplified country of origin, currency, gross mass, number of packages and the procedure code (requested/previous). For certain goods (licences, surveillance) up to 3 extra fields apply, typically bringing the total to 15.

Does the SFD replace the full UK customs declaration?

No. The SFD is the first part of the simplified procedure — it releases goods from the border but does not complete the customs or tax settlement. The second, mandatory step is the Supplementary Declaration (SDP) lodged in CDS by the 10th day of the month after import, with the full data set, 10-digit HS, precise customs value and VAT/duty settlement. No SDP means loss of SCDP authorisation and retrospective duty.

Do you need to supply a precise customs value in an SFD?

No — the SFD accepts a value range instead of an exact amount. The importer declares the bracket in which the consignment's value falls, and the precise customs value, including costs, insurance and commissions, is only supplied in the Supplementary Declaration. This is one of the key simplifications — there is no need to wait at the border for the freight forwarder's final invoice.

Does an SFD require a GB EORI number?

Yes — the importer must hold an EORI number beginning with GB (or XI for Northern Ireland). A customs agent lodging the SFD on behalf of a client must also hold its own GB EORI. Without both numbers, CDS will reject the declaration before the goods data are even validated. See the EORI article for details.

What happens if data in the SFD is inconsistent with the Supplementary Declaration?

HMRC compares the two data sets and any material difference — such as a different HS code, a different country of origin, or a different importer — can lead to retrospective duty and VAT assessments, an administrative penalty, and a warning on the SCDP profile. Repeated inconsistencies lead to authorisation being revoked. That is why the EasyClearance Team checks SFD vs SDP consistency before every supplementary submission.
