What is export customs clearance?
Export customs clearance is the formal process of declaring goods to HMRC before, or when, they leave the UK. It involves filing an export declaration, providing the correct commodity code, and ensuring all required documents are in place. Without clearance, goods cannot lawfully depart the UK. It applies to every commercial shipment leaving Great Britain for any destination outside the UK.
If you are new to shipping, export customs can feel like a maze of acronyms. This article cuts through it, covering who is responsible, what the process involves, what can go wrong, and how to get it right.
Export customs clearance is the process of formally notifying HMRC that goods are leaving the UK. It creates an official record of the shipment and confirms the goods are lawful to export.
It is not the same as import clearance at the destination country, that is a separate process handled at the other end. Export clearance is the UK’s outbound step.
The declaration is filed through HMRC’s Customs Declaration Service (CDS). Once accepted, CDS issues a Movement Reference Number (MRN), which must accompany the goods to the port or airport. The carrier checks this before loading. Without a valid MRN, the goods will not depart.
Export customs clearance is required for all goods leaving Great Britain (England, Scotland, Wales) for any destination outside the UK. It is not required for purely domestic shipments within the UK.
The legal responsibility lies with the exporter of record: the UK business or individual named on the export declaration. This is usually the seller, but not always.
Many exporters use a customs agent or freight forwarder to handle the declaration on their behalf. The agent files the paperwork, but the exporter remains legally accountable for the accuracy of the information provided.
To file or authorise an export declaration, the exporter must have:
If you do not yet have a UK EORI number, apply at gov.uk/eori. It is free and usually issued within 72 hours for VAT-registered businesses.
The process has six core steps. Getting an early step wrong causes problems further down the line.
Step 1: Classify the goods. Find the correct commodity code for your goods. This is an eight-digit number for exports. The code determines whether any restrictions, licences, or prohibitions apply.
Step 2: Check for licences or restrictions. Some goods need an export licence before you can ship them. Check the ECJU’s online checker and HMRC’s prohibitions and restrictions list.
Step 3: Prepare your commercial documents. Gather the commercial invoice, packing list, and any required certificates. These form the factual basis for the export declaration.
Step 4: Submit the export declaration via CDS. File the declaration in HMRC’s Customs Declaration Service, directly if you are authorised, or through a customs agent. CDS returns an MRN when the declaration is accepted.
Step 5: Present the MRN at the port or airport. The MRN must be linked to the shipment before departure. Without it, the goods will not be loaded.
Step 6: Retain proof of export. Once the goods have left the UK, get official confirmation of departure. You need this to support your VAT zero-rating claim.
The documents required depend on the goods and destination. The table below covers the core set for most commercial exports.
| Document | Purpose | Who Produces It |
|---|---|---|
| Commercial Invoice | States the value, description, and parties involved | Exporter |
| Packing List | Details contents, weights, and dimensions | Exporter |
| Export Declaration (MRN) | The formal customs entry filed via CDS | Exporter or customs agent |
| Bill of Lading / Air Waybill | Carrier’s contract and receipt for goods | Freight forwarder or carrier |
| Commodity Code | Eight-digit code classifying the goods | Exporter (with agent support) |
| Certificate of Origin | Confirms where goods were manufactured | Chamber of Commerce or HMRC |
| Export Licence | Authorises export of controlled goods | Export Control Joint Unit (ECJU) |
| EUR.1 / REX Declaration | Preferential origin for certain trade agreements | Exporter or Chamber of Commerce |
| Phytosanitary Certificate | Required for plants and some food products | Animal and Plant Health Agency |
Not every shipment needs every document. Keep records of everything for at least four years. HMRC’s minimum requirement.
Most exporters file their declaration in CDS before the goods leave. But there is an alternative route called Entry in Declarant’s Records (EIDR).
Under EIDR, you record the shipment in your own commercial records at the time of export and submit a supplementary declaration to HMRC afterwards, usually by the fourth working day of the following month.
EIDR reduces administrative pressure at the point of export, but you need HMRC authorisation to use it and must maintain auditable records. It suits businesses with regular, high-volume exports. If you are starting out, a standard pre-departure declaration via CDS is simpler and lower risk.
Every item you export needs a commodity code. For exports, this is an eight-digit number from the UK Global Trade Tariff. It tells HMRC, and the destination country’s customs authority, exactly what the goods are.
Getting the code wrong can result in the wrong licences being identified (or missed), customs delays, HMRC penalties, and the loss of preferential duty rates under trade agreements.
Use the UK Global Trade Tariff to find the right code. If you are unsure, you can apply to HMRC for a Binding Tariff Information (BTI) ruling, a formal, legally binding classification.
Some commodity codes carry restrictions or prohibitions on export. Always check the code against the current restrictions list before you book the shipment.
When you export goods from the UK, the sale is zero-rated for UK VAT, you charge 0% rather than 20%. But zero-rating is not automatic. You must prove that the goods actually left the UK.
If you cannot prove this, HMRC can reclaim the VAT that should have been charged, plus interest and potentially penalties.
Acceptable proof of export includes:
HMRC gives you three months from the date of supply to get proof. If you cannot get it within that window, charge VAT on the supply and adjust your return when proof arrives. Keep proof of export records for at least six years if VAT is involved.
Most goods can be exported freely. But some require a licence from the government before they can lawfully leave the UK. Categories where a licence is most likely include:
Licences are issued by the Export Control Joint Unit (ECJU), operating within the Department for Business and Trade, via the SPIRE online system.
Always check before you ship. Exporting controlled goods without a licence is a criminal offence. Processing times vary from a few weeks to several months, build this into your planning timeline.
Dual-use goods are products with legitimate civilian uses that could also serve military purposes. The category is broader than most expect, high-performance computing, encryption software, certain optical equipment, industrial chemicals, and navigation technology can all fall within it.
The UK Dual-Use Regulation controls these goods. The ECJU maintains the UK Strategic Export Control Lists, which set out exactly which goods are controlled and under what conditions.
Even if a product is not on the control lists, you may still need a licence if you know or suspect it will be used for military, WMD-related, or sanctioned purposes. This is the end-use control, it applies regardless of what the goods are. The ECJU offers a free pre-application advice service, use it when you are uncertain.
The Incoterm in your sales contract determines who is responsible for arranging export customs clearance. This affects your obligations, your costs, and your risk.
| Incoterm | Who Handles Export Clearance | Notes |
|---|---|---|
| EXW (Ex Works) | Buyer | Buyer takes responsibility from the seller’s premises. In practice, the seller often needs to cooperate with documents. |
| FCA (Free Carrier) | Seller | Seller clears for export and delivers to a named point. Most practical for UK exporters. |
| FAS (Free Alongside Ship) | Seller | Seller clears export and delivers alongside the vessel. |
| FOB (Free On Board) | Seller | Seller clears export and delivers goods on board the vessel. |
| CFR / CIF | Seller | Seller clears export and arranges freight to the destination port. |
| CPT / CIP | Seller | Seller clears export and pays freight to the named destination. |
| DAP / DPU / DDP | Seller | Seller handles export clearance in all cases. Under DDP, the seller also handles import at destination. |
A note on EXW. Under EXW, the buyer is nominally responsible for export customs. But overseas buyers often cannot practically access CDS or act as UK exporter of record. In most EXW transactions, the seller cooperates anyway. For most UK exporters, FCA is a more workable starting point.
Most export customs problems come down to the same recurring errors.
No EORI number. You cannot file an export declaration without a UK EORI. Apply early, do not wait until a shipment is ready.
Wrong commodity code. An incorrect code can trigger missed licences or customs delays at destination. Always verify using the UK Global Trade Tariff.
Incorrect goods value on the invoice. Undervaluing goods to reduce duties is a customs offence. Overvaluing can create problems with VAT and destination duties.
Failing to retain proof of export. Without it, you cannot defend a VAT zero-rating claim. HMRC audits this, sometimes years after the fact.
Missing or late export declaration. Goods arriving at the port without an MRN will be stopped. Last-minute declarations cause delays and can miss vessel cutoffs.
Not checking for export licences. Assuming goods are freely exportable without checking the control lists is a common and serious error.
Ignoring sanctions. UK sanctions change regularly. Shipping goods to a sanctioned destination or individual is a criminal offence. Check the OFSI sanctions list for every unfamiliar destination.
Brexit changed export customs majorly for UK businesses. Here is what it means for the three main trade routes.
GB to EU. Before Brexit, UK businesses exported to the EU without customs declarations, it was a single market. Now, exports from Great Britain to EU member states require a full UK export declaration and a separate EU import declaration at the other end. Your goods need an MRN from CDS before they leave. Your EU customer handles their own import clearance, paying applicable EU customs duties and VAT.
GB to Northern Ireland. Northern Ireland sits under the Windsor Framework. Most goods sold and consumed in Northern Ireland qualify under the UK Internal Market Scheme (UKIMS) and use simplified procedures. This area is evolving, check HMRC guidance regularly.
GB to Rest of World. For non-EU countries, the core process is unchanged. You need an export declaration via CDS, an EORI number, and the correct commodity code. The main change post-Brexit is that the EU no longer gets simpler treatment, every destination requires the same level of compliance.
Scenario: A UK manufacturer in Birmingham is exporting industrial sensors to a customer in Germany. Invoice value: £18,500. Terms: FCA. The German customer has arranged their own freight forwarder for the EU import leg.
What the UK exporter does:
The German freight forwarder handles the EU import declaration at the other end. The UK exporter has no responsibility for the import side under FCA terms.
Approximate cost for export customs on this shipment: £60–£120 in customs agent fees.
Do I need to file an export declaration for every shipment?
Yes, for all commercial goods leaving Great Britain for any destination outside the UK. Minor exceptions exist: for example, certain low-value consignments, but for standard commercial trade, declarations are required every time.
Can my freight forwarder file the export declaration for me?
Yes. Most freight forwarders and customs agents offer this as a service. You remain legally responsible for the accuracy of the information you provide to them.
How much does it cost to get an EORI number?
Nothing. A UK EORI number is free. Apply at gov.uk/eori.
What is the Movement Reference Number (MRN)?
The MRN is the unique reference generated by CDS when your export declaration is accepted. It is presented at the port to confirm the goods have been declared. Without it, your goods will not be cleared for departure.
How long do I have to get proof of export for VAT purposes?
Three months from the date of supply. If you cannot get proof within that window, account for VAT on the supply and adjust your return when proof arrives.
Do I need an export licence for goods going to the EU?
It depends on the goods, not the destination. EU member states are not automatically exempt from UK export controls. Strategic and dual-use goods require a licence regardless of whether the destination is in the EU.
What happens if I export without filing a declaration?
It is a customs offence. HMRC can impose financial penalties, and in serious cases, particularly where export licences were also missing, prosecution is possible.
How do I know if my goods are dual-use?
Check the UK Strategic Export Control Lists published by the ECJU. If you are unsure after checking, contact the ECJU directly or use their free pre-application advice service.
