A certificate of origin is one of the most important documents in international trade. It is also one of the most misunderstood. Get it wrong and your shipment could face delays, unexpected duties, or rejection at the border.
This article explains what a certificate of origin is, the different types used in UK trade, how post-Brexit rules changed things, and how to apply for one.
A certificate of origin (CoO) is an official document that certifies the country in which goods were produced, manufactured, or substantially processed. Customs authorities, importers, and banks use it to decide how goods should be treated at the border, including which duty rate applies.
In simple terms, it answers the question: where do these goods actually come from?
That question matters more than you might think. The country of origin affects the duty rate, whether trade sanctions apply, and whether your buyer’s bank will release payment under a letter of credit.
Without a certificate of origin, your goods may be taxed at the standard (most-favoured-nation) rate. That rate can be much higher than the preferential rate available under a trade agreement.
This is the most important distinction to understand. Not all certificates of origin do the same job.
| Feature | Non-Preferential CoO | Preferential CoO |
|---|---|---|
| What it proves | Country of origin | Country of origin + compliance with trade agreement rules |
| Duty benefit | None — standard rates apply | Reduced or zero tariff rate under a trade agreement |
| Common uses | Letters of credit, customs compliance, commercial records | Claiming preferential duty under TCA, GSP, or bilateral agreements |
| Examples | Standard Chamber of Commerce CoO | EUR1, ATR1, GSP Form A, REX declaration |
| Who typically needs it | Importers, banks, buyers requiring origin proof | Exporters claiming tariff concessions |
Non-preferential certificates confirm where goods came from. They are used for business, statistical, and banking purposes, but they do not reduce the duty your buyer pays.
Preferential certificates go further. They confirm that the goods meet the specific rules of origin set out in a trade agreement. If the importing country’s customs accept them, the buyer pays a reduced or zero tariff rate.
If you are exporting to the EU and want your buyer to benefit from the UK-EU Trade and Cooperation Agreement (TCA) zero tariffs, you need a preferential certificate. A standard Chamber of Commerce CoO is not enough.
You will typically need a certificate of origin in the following situations:
Not every shipment requires one. If you are exporting to a country with no trade agreement, or if the duty rate is the same regardless of origin, a CoO may be optional. Always check the specific requirements of the destination country before shipping.
| Document | When Used | Who Issues It |
|---|---|---|
| Standard Certificate of Origin | General trade, letters of credit, non-preferential customs requirements | UK Chambers of Commerce (e.g., BCC, LCCI) |
| EUR1 Movement Certificate | UK-EU trade under the TCA — to claim preferential (zero) tariff rates | HMRC (exporter applies; HMRC endorses) |
| ATR1 Certificate | UK-Turkey trade — to claim preferential treatment under the UK-Turkey trade agreement | HMRC |
| GSP Form A | Imports from developing countries into the UK — to claim reduced import duty | Issued by authorities in the exporting country |
| REX Declaration | Alternative to EUR1 for registered exporters trading with the EU or GSP countries | Self-declared by registered exporters (REX registered) |
| Arab-British CoO | Trade with Arab League member states | Arab-British Chamber of Commerce |
Each document serves a specific trade corridor or purpose. Using the wrong one, or using a non-preferential CoO when a preferential one is needed, means your buyer pays full duty rates.
The standard certificate of origin is a non-preferential document. UK Chambers of Commerce issue it to certify where your goods were produced or manufactured.
It is widely used when:
The standard CoO does not grant preferential duty rates. It simply proves origin.
Cost: around £15–£50 per certificate, depending on the issuing chamber. The British Chambers of Commerce (BCC) and the London Chamber of Commerce and Industry (LCCI) are the two main issuers in the UK.
Format: typically an A4 document with your company details, a description of the goods, the HS code, the country of origin, and a declaration signed by an authorised signatory. The chamber stamps and certifies it.
Some chambers offer online applications, which speeds up the process significantly.
The EUR1 movement certificate is a preferential certificate of origin. It is used in trade between the UK and the European Union under the Trade and Cooperation Agreement (TCA).
If a UK exporter wants their EU buyer to pay zero tariffs under the TCA, the goods must be accompanied by either:
The EUR1 is one of the most important documents for UK exporters post-Brexit. Before the UK left the EU, origin certificates were not needed for intra-EU trade. Now they are essential if you want your EU customers to benefit from preferential duty rates.
Who issues it: HMRC. The exporter completes the form and submits it to HMRC for endorsement. HMRC stamps the certificate, which is then sent with the goods.
Key requirement: the goods must meet the TCA’s rules of origin. Simply shipping goods via the UK is not enough. The goods must genuinely originate in the UK (or the EU) to qualify.
For a full breakdown of how the EUR1 works, see our dedicated guide: EUR1 Movement Certificate. Complete Guide.
The ATR1 certificate is a preferential movement certificate. It is used in trade between the UK and Turkey.
It allows goods of UK origin to enter Turkey at preferential (reduced) duty rates. Turkish goods can also enter the UK at preferential rates under the UK-Turkey bilateral trade agreement.
The ATR1 works differently from the EUR1. It does not require strict rules of origin compliance in the same way. Instead, it certifies that the goods are in free circulation in the UK. That means any customs duties have already been paid, or the goods were produced in the UK.
Who issues it: HMRC endorses ATR1 certificates in the UK.
When you need it: when exporting goods to Turkey and you want your buyer to benefit from preferential tariff treatment.
For more detail, see our dedicated guide: ATR1 Certificate. UK-Turkey Trade Explained.
The Generalised Scheme of Preferences (GSP) allows the UK to grant reduced or zero import duty rates on goods from developing countries.
Form A (also called the Generalised System of Preferences Certificate of Origin) is the document UK importers use to claim this preferential rate.
Your supplier in the developing country must get and provide the Form A. It is issued by the authorities of the exporting developing country: not by the UK importer.
Key points:
If you import regularly from GSP-eligible countries, making sure your supplier provides a valid Form A can save a significant amount in import duty.
Rules of origin are the criteria that determine whether goods “originate” in a particular country for the purposes of a trade agreement.
This is critical for preferential certificates. You cannot simply declare that goods originate in the UK and claim preferential rates. The goods must genuinely qualify under the specific rules set out in the relevant trade agreement.
The main tests used are:
Why does this matter? Suppose you import components from China, assemble them in the UK, and export the finished product to the EU. You need to check whether the assembly process is enough to give the product UK origin under the TCA rules.
If the goods do not meet the rules of origin, you cannot use an EUR1 or any other preferential certificate. Using one anyway is a misdeclaration, a serious offence (see below).
The TCA rules of origin are product-specific and can be complex. For high-value or high-volume exports, it is worth speaking to a customs adviser.
Different types of CoO are issued by different authorities:
| Certificate | Issuing Authority |
|---|---|
| Standard CoO | UK Chambers of Commerce (BCC, LCCI, and regional chambers) |
| EUR1 | HMRC (exporter submits; HMRC endorses) |
| ATR1 | HMRC (exporter submits; HMRC endorses) |
| Form A (GSP) | Qualified authority in the exporting developing country |
| Arab-British CoO | Arab-British Chamber of Commerce |
| REX declaration | Self-declared by the exporter (must be REX-registered) |
For standard CoOs, most chambers now offer online applications through platforms such as the LCCI’s eCert system or the BCC’s own portal.
The process is straightforward:
Cost: £15–£50 depending on chamber. Some chambers charge extra for same-day service.
Processing time: usually 1–2 working days for standard applications; same-day available at many chambers.
For frequent exporters to the EU, it may be worth registering as a Registered Exporter (REX). This lets you self-declare origin on your invoice rather than applying for an EUR1 each time.
Using a false or inaccurate certificate of origin is a serious offence in the UK.
HMRC and border agencies actively check certificates of origin, particularly for:
Common types of misdeclaration include:
Consequences can include:
If you are unsure whether your goods meet the rules of origin, get advice before applying for a preferential CoO. It is far better to pay the standard duty rate than to risk a misdeclaration.
Brexit fundamentally changed the certificate of origin landscape for UK businesses.
Before 31 December 2020, UK companies trading with EU member states did not need certificates of origin. Goods moved freely within the single market. Origin documents were only relevant for trade with non-EU countries.
Post-Brexit, everything changed:
New post-Brexit documents relevant to UK exporters:
| Document | Purpose |
|---|---|
| EUR1 Movement Certificate | Claiming TCA preferential rates on UK-EU exports |
| Statement on Origin | Self-declaration alternative to EUR1 (value limits apply unless REX-registered) |
| REX (Registered Exporter) | Allows self-declaration of origin for EU trade and GSP |
| ATR1 | Preferential trade with Turkey under UK-Turkey agreement |
Many UK businesses, particularly SMEs, were caught unprepared by these changes. Some EU buyers began paying full tariffs because their UK suppliers did not provide the correct origin documents.
If you are exporting to the EU and not yet using EUR1 certificates or REX declarations, you may be costing your buyers money and putting your trading relationships at risk.
Here is a practical scenario that shows why getting the right certificate matters.
The situation: A UK manufacturer in the West Midlands produces precision-engineered metal components. Their long-standing customer is a German engineering firm. The goods are classified under HS code 8483 and attract a 2.7% EU import duty under the standard MFN rate.
The TCA: Under the UK-EU TCA, these goods qualify for a zero tariff rate, but only if the UK manufacturer can prove the goods originate in the UK and meet the TCA rules of origin.
What the manufacturer does wrong (at first): They apply for a standard certificate of origin from their local Chamber of Commerce. This confirms the goods were made in the UK, but it is a non-preferential document. The German customs authority does not accept it as evidence of TCA origin. The German buyer pays the full 2.7% duty.
What the manufacturer should do: Apply to HMRC for an EUR1 movement certificate (or register as a REX exporter and include a statement on origin on the invoice). This is the correct preferential document under the TCA. When submitted to German customs, it triggers the zero tariff rate.
The lesson: A standard Chamber of Commerce CoO and an EUR1 are not the same thing. For UK-EU trade under the TCA, only a preferential certificate unlocks zero tariffs.
Do I always need a certificate of origin when exporting from the UK?
No. A CoO is not required for every shipment. You need one when the destination country’s customs require it, when your buyer’s bank requires it for a letter of credit, or when you want to claim preferential (reduced) duty rates under a trade agreement.
What is the difference between a CoO and an EUR1?
A standard CoO is a non-preferential document that proves where goods were made. An EUR1 is a preferential document. It also confirms the goods meet the TCA rules of origin, so your EU buyer can pay zero tariffs. For UK-EU trade under the TCA, you need an EUR1 (not a standard CoO) to access preferential rates.
How much does a certificate of origin cost in the UK?
A standard CoO from a UK Chamber of Commerce costs around £15–£50. EUR1 certificates issued by HMRC do not carry a direct government fee, but there may be admin costs if you use a freight forwarder or customs agent to help with the application.
Can I use a standard CoO instead of an EUR1 for EU exports?
No. A standard CoO does not grant preferential duty treatment under the TCA. It is a non-preferential document. To claim zero tariffs under the TCA, you must use an EUR1 movement certificate or a valid statement on origin.
What happens if I get my certificate of origin wrong?
If you use an incorrect or fraudulent CoO, your buyer may face retrospective duty demands from their customs authority. You as the exporter could face penalties, fines, or criminal charges. HMRC and border agencies actively audit certificates of origin.
What is a REX declaration and when can I use it?
REX stands for Registered Exporter. Once registered with HMRC, you can self-declare the origin of your goods on the invoice or other commercial document, instead of applying for an EUR1 for each shipment. It is particularly useful for frequent exporters to the EU or GSP-eligible countries.
Do I need a certificate of origin for imports as well as exports?
Yes, in some cases. If you import goods from a developing country and want to claim reduced duty under the UK’s GSP, your overseas supplier must provide a GSP Form A (or equivalent). You do not apply for it yourself. The supplier gets it from their country’s issuing authority.
How long is a certificate of origin valid?
This depends on the type and the destination country’s requirements. EUR1 certificates are generally valid for four months from the date of endorsement. Standard CoOs do not expire, but buyers and customs authorities may question documents that are very old relative to the shipment date. Always check the specific requirements for the destination country.
