UK export declaration: how export customs clearance works

Every commercial export from Great Britain needs an export declaration in CDS and customs clearance before the goods leave. This guide explains what the UK export declaration contains, when it must be submitted, how exit is confirmed and why that confirmation matters for zero-rated VAT.

What export customs clearance in the UK actually is

Export customs clearance is HMRC's permission for goods to leave the UK. Gov.uk says you or your representative must submit an export declaration and get clearance from customs before the goods are allowed to leave. The declaration is made in the Customs Declaration Service (CDS), online or through commercial software. The process ends when HMRC receives a departure message confirming the goods have gone, and that message is what turns the declaration into proof of export for VAT.

This guide follows a UK export declaration from preparation to departure. For the paperwork that travels with the goods, see our guide to export documents, packing lists and invoices.

Before the declaration: four things to settle

• EORI. You need an EORI number starting with GB to export goods from England, Wales or Scotland.
• Licences and restrictions. Gov.uk lists goods that may need licences or certificates, from animals and plants to chemicals, art and dual-use items. Check both UK rules and the destination country's rules.
• Commodity code. You must find the right commodity code for the goods.
• Who will declare. You can make the declaration yourself or hire someone to deal with customs for you.

If you hire someone, they must be established in the UK for customs, and they cannot act for you without written instructions that say whether they act directly or indirectly. Under direct representation you remain liable for the declaration; under indirect representation the agent is jointly liable with you. Either way, HMRC says you remain responsible for due diligence on declarations made for you.

What goes into a UK export declaration

HMRC's guidance on full export declarations says the declaration must include:

• the customs procedure code (see our guide to customs procedure codes);
• the commodity code;
• a Declaration Unique Consignment Reference (DUCR), the main reference that links declarations.

You also give the departure point and destination, the consignor and consignee, the type, amount and packaging of the goods, transport methods and costs, currencies and valuation methods, and any certificates and licences. Gov.uk asks you to complete it using the declaration completion requirements for Great Britain if you are exporting from England, Scotland or Wales.

When to submit: arrived or pre-lodged

Timing depends on where the goods leave from. Some departure locations require the export declaration to be submitted as "arrived". At those locations, the declaration must be in before the goods start their journey to the border. Everywhere else, the declaration must be submitted before the goods are presented to customs at the UK border, which in practice means it is pre-lodged. At ports using the Goods Vehicle Movement Service (GVMS), HMRC confirms that export declarations can be pre-lodged or arrived depending on the location you are leaving from.

There are also minimum lead times, set by the last mode of transport:

Exit: the departure message

After clearance, HMRC needs to be told that the goods have left the UK. This departure message is sent by systems at the point of departure, at locations that use an inventory linked system, GVMS or an approved loader. If you export from another location, you have to report to HMRC when the goods are presented at the port of departure and when they have left.

On roll-on roll-off routes, the haulier's goods movement reference is the link. For an export declaration, the DUCR is the reference added to the GMR, and HMRC asks exporters to make sure their hauliers include all DUCRs in the GMR so that departure messages are sent.

Proof of export and zero-rated VAT

Exported goods may be zero-rated for VAT, but only with evidence. Under VAT Notice 703, official evidence is a CDS export declaration that has generated a departure confirmation, identified by its Movement Reference Number or DUCR. Commercial evidence, such as a CMR fully completed by consignor, haulier and consignee, or authenticated waybills, can be used instead. HMRC treats the two as generally equally valid, but if one lacks detail you need the other.

For direct exports and ex-works indirect exports, the goods must be exported and the evidence obtained within 3 months of the time of supply. If either is missing, you must not zero-rate the supply and must account for VAT at the UK rate. Where an overseas customer collects the goods, HMRC sets a high standard of evidence and notes that copies of transport documents alone will not be enough.

Regular exporters: simplified declarations

Businesses with a good compliance record and a regular pattern of declarations can apply, on form C&E48, to use simplified declarations for exports. The declaration is split into two parts linked by the same DUCR. The supplementary declaration is due within 14 days of the goods departing the UK, or by the 10th calendar day of the following month if the movement includes more than one consignment. Simplified declarations cannot be used for goods that are subject to export licensing or excise duty, except where exceptions apply.

Corrections and records

You can amend an export declaration before it has been cleared by customs. HMRC's guidance adds that the statistical record can be amended up to 3 years after clearance, and that amending a licensable export after clearance needs an online C1700 form. Keep commercial invoices and customs paperwork, and, if you are VAT registered, record exported goods in your VAT accounts even when they are zero-rated.
