Certificate eur1: what UK exporters need to know after Brexit

Why the EUR.1 certificate still causes confusion

Brexit changed the paperwork behind UK exports to Europe. For many businesses, one document remains at the centre of the confusion: the EUR.1 movement certificate.

Before the UK left the European Union, goods moved freely between the UK and EU without customs declarations or preferential origin paperwork. That changed on 1 January 2021. Customs declarations became mandatory, and businesses had to demonstrate the origin of their goods if they wanted to claim reduced or zero tariffs under the EU-UK Trade and Cooperation Agreement (TCA).

But the key point is often missed: the EUR.1 certificate is generally not the standard proof of origin for trade between the UK and the EU under the TCA. In most cases, UK exporters must use a statement on origin instead.

That distinction matters. Using the wrong document can delay a shipment, lead to an incorrect tariff claim or leave an exporter facing an unexpected customs bill for the customer.

What the EUR.1 certificate does

A EUR.1 certificate is a preferential origin document. It confirms that goods meet the origin rules set out in a specific trade agreement between the exporting and importing countries.

When accepted, it allows the importer to claim a reduced rate of customs duty, or in some cases duty-free treatment. The certificate is normally issued or validated by the customs authorities in the exporting country.

The document does not prove where goods were shipped from. It proves where they originate for trade agreement purposes. Those are not always the same thing.

For example, a UK company may export a machine from a warehouse in Birmingham. If the machine contains components manufactured in several countries, its preferential origin will depend on the relevant rules. The fact that it leaves from the UK does not automatically make it a UK-origin product.

This is the principle that catches out many new exporters. Origin is based on manufacturing and processing rules, not simply on the location of the seller, warehouse or dispatch point.

Is a EUR.1 required for exports from the UK to the EU?

Usually, no.

Under the UK-EU Trade and Cooperation Agreement, exporters generally prove preferential origin through a statement on origin. This statement is placed on an invoice or another commercial document that identifies the originating goods clearly.

The statement is not a separate certificate issued by HM Revenue and Customs. The exporter makes the declaration and accepts responsibility for ensuring that the goods meet the applicable rules of origin.

For consignments with a total value of up to €6,000, any exporter may normally make the statement on origin. For consignments above €6,000, the exporter generally needs to include a UK exporter reference number, usually the exporter’s Economic Operators Registration and Identification (EORI) number.

The exact wording matters. A typical statement refers to the goods having UK preferential origin and includes the relevant exporter reference where required. Exporters should use the wording published in the official UK-EU trade guidance rather than relying on an improvised sentence.

Importers may also claim preference based on “importer’s knowledge”. This means the importer makes the claim using information demonstrating that the goods meet the origin requirements. In practice, this can be useful where the importer holds detailed records, but it does not remove the need for accurate origin evidence.

When can UK exporters use a EUR.1 certificate?

The EUR.1 remains relevant in some UK trade relationships outside the EU, depending on the agreement in force with the destination country.

The UK has its own network of trade agreements and continuity agreements. Some may provide for a EUR.1 certificate, while others may use an origin declaration, a statement on origin or another form of proof.

There is no universal rule that applies to every market. A UK exporter sending goods to Switzerland, Turkey, Canada, Mexico or a country covered by another agreement must check the specific arrangement before shipping. The documentation required can differ according to:

• The destination country.
• The value and nature of the consignment.
• The trade agreement being used.
• The product’s classification under the Harmonised System.
• Whether the exporter is approved or registered under the relevant scheme.
• Whether the goods qualify as originating under the agreement’s product-specific rules.

In some cases, an EUR.1 must be obtained from customs before export. In others, the exporter must issue an origin declaration directly. Some agreements use a registered exporter system, while others set different value thresholds or certification requirements.

The safest approach is straightforward: identify the agreement first, then check its origin proof requirements. Starting with the document rather than the agreement is how mistakes begin.

Preferential origin is not the same as UK origin

A product can be sold by a UK business, shipped from the UK and still fail to qualify for preferential UK origin.

Consider a company importing finished electronic devices from Asia and reselling them to a customer in France. The goods may pass through the UK, be stored in a UK warehouse and be invoiced by a British business. Unless sufficient processing takes place in the UK under the relevant rules, the devices will not normally qualify as UK-originating goods under the TCA.

Simple operations such as packaging, labelling, sorting or storage usually do not confer origin. More substantial processing may qualify, but the answer depends on the product and the agreement.

Rules can include a change in tariff classification, a maximum percentage of non-originating materials, a minimum level of processing or a specific manufacturing operation. The test is different for different products.

For businesses using imported components, this means origin should be assessed before the goods are sold, not when a customs query arrives. A spreadsheet showing suppliers, component origins, tariff codes and manufacturing steps can be more valuable than a filing cabinet full of invoices.

What information should exporters keep?

When an exporter issues a statement on origin, it must be able to support the claim. Customs authorities can request evidence from the exporter or ask the relevant customs authority to verify the declaration.

Useful records may include:

• Supplier declarations confirming the origin of materials.
• Commercial invoices and purchase records.
• Manufacturing records showing the processes carried out in the UK.
• Product descriptions and technical specifications.
• Commodity codes and origin calculations.
• Production bills of materials.
• Transport and export documentation.
• Copies of statements on origin issued to customers.

Records should be consistent. If the invoice describes a product as “manufactured in the UK” but production records show that it was merely repackaged, the wording may create unnecessary risk.

Businesses should also review their origin analysis when suppliers, product designs or manufacturing locations change. A product that qualified last year may not qualify after a new component is sourced from outside the UK or the EU.

The role of the EORI number

Any business importing into or exporting from the UK will generally need a UK EORI number. Businesses trading with the EU may also need an EU EORI number if they are responsible for customs activities in an EU member state.

The EORI number is not itself proof of origin. It identifies the trader for customs purposes. However, for higher-value consignments under the UK-EU agreement, the exporter’s reference number is normally included in the statement on origin.

Exporters should ensure that the number is entered accurately and consistently. A missing or incorrect reference can cause an importer to lose access to preferential treatment, even where the goods themselves meet the origin rules.

This is a small administrative detail with potentially expensive consequences. Customs systems are not known for rewarding creative interpretation of missing digits.

How to prepare a statement on origin

The statement should appear on an invoice or another commercial document that describes the originating goods in enough detail for customs to identify them. It should not be attached to an unrelated document or written so broadly that it is unclear which products are covered.

For a mixed shipment, exporters must distinguish between qualifying and non-qualifying goods. A statement covering an entire invoice may be misleading if only some products meet the origin requirements.

The exporter should also check the language and wording required under the relevant agreement. The UK-EU TCA contains prescribed wording, and other agreements may use different formulations.

Where a business issues statements regularly, it should create an internal process. Staff preparing invoices need to know which products qualify, which do not and where the supporting records are stored. Sales teams should not promise “duty-free delivery” before the customs and origin position has been checked.

Common mistakes after Brexit

Several errors appear repeatedly in customs reviews and shipment disputes.

• Assuming every European shipment needs a EUR.1: Under the UK-EU TCA, a statement on origin is normally the relevant document.
• Assuming every UK export qualifies for zero duty: Preferential treatment applies only when the goods meet the agreement’s origin rules.
• Confusing dispatch with origin: Goods shipped from the UK are not automatically UK-originating.
• Using an old template: Documentation copied from a previous agreement may contain incorrect wording or references.
• Ignoring product-specific rules: General assumptions about manufacturing are not enough.
• Failing to keep evidence: A declaration without supporting records is difficult to defend.
• Overlooking the importer’s responsibilities: The importer must make a correct customs claim and may request additional evidence.

Another frequent problem arises when a UK business sells goods that originated in the EU. Under the TCA, EU-originating materials may count towards UK origin in certain circumstances, and UK-originating materials may receive equivalent treatment in the EU. But this does not mean that every imported product automatically qualifies. The full rule still has to be applied.

A practical checklist for UK exporters

Before sending goods to the EU or another overseas market, exporters should ask five basic questions.

• Which trade agreement applies to this shipment?
• What are the product’s correct commodity code and origin rules?
• Do the goods meet the agreement’s preferential origin requirements?
• What proof of origin is accepted: a statement, EUR.1, importer’s knowledge or another document?
• Do we have records to support the claim?

For UK-EU shipments, the next step is usually to prepare the correct statement on origin and include it on the commercial document. For other destinations, the exporter should consult the relevant UK government guidance, customs authority or qualified customs adviser before relying on an EUR.1.

Businesses should also agree with their customers who will make the import declaration, who will claim preference and who will provide further information if customs authorities ask questions. Clear responsibilities prevent disputes after the goods have crossed the border.

Why getting it right matters

The financial impact of an origin error can extend beyond one shipment. An importer may be required to pay the full customs duty, interest or penalties. A customer may then seek reimbursement from the exporter, particularly if the exporter promised preferential treatment.

Repeated errors can attract closer customs scrutiny and disrupt supply chains. For smaller exporters, the damage may be disproportionate: one delayed consignment can affect production schedules, cash flow and customer relationships.

The answer is not to avoid preferential claims altogether. When the goods qualify, reduced or zero duty can make a meaningful difference to competitiveness. The answer is to treat origin as a compliance process rather than an afterthought.

Brexit did not make the EUR.1 certificate obsolete in every UK trade relationship. It did, however, make it essential to understand which agreement applies and which proof of origin that agreement accepts. For exports from Great Britain to the EU under the current framework, that usually means a properly prepared statement on origin, backed by reliable records.

The document may be short. The analysis behind it should not be.
