What are rules of origin?
Rules of origin are the criteria used in international trade to determine the “economic nationality” of goods, in other words, which country a product genuinely “comes from” for trade purposes. They decide whether goods qualify for reduced or zero duty under a free trade agreement, and they underpin a wide range of other trade measures, from anti-dumping duties to trade statistics. For UK businesses trading with the EU under the Trade and Cooperation Agreement (TCA), rules of origin are one of the most important, and most commonly misunderstood, parts of post-Brexit trade.
Has someone mentioned “rules of origin” as a reason a customer may face unexpected duty charges? This article explains what they are. It covers how they work and why they matter for UK businesses exporting to the EU.
Rules of origin sit at the heart of international trade policy. Get them right and your customers benefit from zero or reduced duty at the border. Get them wrong and goods that should be duty-free end up attracting full tariff rates. Sometimes nobody realises until HMRC or the destination customs authority comes asking.
Rules of origin are a set of criteria used to establish the country of origin of a product. This is not the same as the country the goods were shipped from. A T-shirt shipped from the Netherlands might have been manufactured in Bangladesh. Its country of origin is Bangladesh, not the Netherlands.
The distinction matters enormously. Customs authorities use country of origin to apply the right duty rate and to enforce trade sanctions. They also use it to decide whether a shipment gets the preferential duty rate under a trade agreement.
Rules of origin answer the question: where was this product really made?
That question is straightforward for a block of granite cut from a Scottish quarry. It is much harder to answer for a product assembled from components sourced across six different countries.
The UK has trade agreements with over 70 countries and territories. The most important for most UK businesses is the EU under the Trade and Cooperation Agreement (TCA).
Under the TCA, goods of UK origin exported to the EU can enter at zero duty. Goods of EU origin imported into the UK from the EU also attract zero duty. These are “preferential” tariff rates, better than the standard rates that apply without a trade agreement.
But zero duty is not automatic. To claim it, the exporter must prove that the goods actually originate in the UK. The same applies to EU exporters claiming preference in the UK. Rules of origin are the rules that determine whether that proof holds up.
If your goods fail the TCA origin rules, your EU customer pays the standard MFN duty rate instead. MFN stands for Most Favoured Nation. For manufactured goods, that can be anywhere from a few percent to 12% for clothing or more. On a high-value shipment, that is a significant extra cost.
This is why rules of origin are not just a paperwork formality. They directly affect price and customer relationships.
There are two distinct categories of rules of origin, and they serve different purposes.
| Feature | Preferential Rules of Origin | Non-Preferential Rules of Origin |
|---|---|---|
| Purpose | Determines whether goods qualify for reduced or zero duty under a trade agreement | Determines country of origin for all other trade policy purposes |
| When it applies | When claiming preference under an FTA or GSP scheme | Anti-dumping duties, safeguard measures, trade statistics, trade embargoes, public procurement |
| Set by | The specific trade agreement (e.g. TCA Annex ORIG-2) | UK domestic legislation |
| Test stringency | Usually strict — goods must meet product-specific rules | Generally uses the “last substantial transformation” principle |
| Documentation required | Supplier declarations, statement on origin | Certificate of origin (often from a Chamber of Commerce) |
| Example | UK clothing exported to EU claiming TCA zero duty | Identifying origin for anti-dumping duty on Chinese steel |
The key takeaway: preferential origin is what you need to claim duty savings under a free trade agreement. Non-preferential origin covers everything else: sanctions, statistics, anti-dumping measures, and public procurement rules.
This article focuses mainly on preferential origin. That is where the stakes are highest for most UK exporters.
Every preferential rules of origin framework, including the TCA, builds its product-specific rules around two fundamental tests.
Test 1: Wholly got
The goods were entirely produced or got in one country, with no materials from anywhere else. This applies mainly to natural products, agricultural goods, minerals, and livestock.
Test 2: enough Processing
The goods were made using materials from other countries. Those materials were processed or transformed enough in the claiming country to confer origin. This is the test that applies to most manufactured goods.
Most product-specific rules will specify which test applies, or a combination of both. For a manufactured product using imported components, you will almost always be looking at the enough processing test.
The wholly got test is the simpler of the two. It applies where every element of the product originates in a single country. Under the TCA and most UK trade agreements, wholly got goods include:
A fresh Scottish salmon is wholly got in the UK. A block of Welsh slate quarried in Wales is wholly got in the UK. A jersey lamb raised in New Zealand is wholly got in New Zealand.
The moment any material from another country enters the production process, the wholly got test no longer applies. You move to the enough processing test instead.
enough processing checks whether goods made from imported materials were transformed enough to take on a new origin. The new origin is the country where that processing happened.
The test exists because most manufactured goods contain inputs from multiple countries. The question is: did enough transformation happen in one country to call it the product’s origin?
“enough” does not mean “most.” A product can be UK origin even when most materials came from abroad. This holds as long as the UK processing meets the relevant rule.
There are three main criteria used to define enough processing:
1. Tariff Classification Change (TCC)
The finished goods must fall under a different HS tariff heading from the input materials. This signals that a meaningful transformation has occurred. The exact level of change required, chapter, heading, or subheading, varies by product.
2. Value Added Test (VA)
A minimum percentage of the product’s value must have been added in the country of origin. The threshold varies by agreement and product. Under the TCA, this is often expressed as a maximum non-originating content threshold. For example, no more than 50% of the ex-works price may consist of non-originating materials.
3. Specific Process Requirements
Certain products must go through specific manufacturing processes to qualify. The rules specify the processes, not just the transformation outcome. For some textile and apparel products, yarn must be spun or fabric woven in the country of origin. This applies regardless of where the raw fibre came from.
The table below shows the three main enough processing criteria, how they work, and where each applies.
| Criterion | How It Works | Typical Application |
|---|---|---|
| Tariff Classification Change (TCC) | Goods must move to a different HS chapter, heading, or subheading after processing | Engineering, chemicals, electronics, food processing |
| Value Added (VA) / Max Non-Originating Content | Local value added must exceed a threshold, or non-originating content must not exceed a maximum percentage of ex-works price | Automotive, machinery, mixed-material products |
| Specific Process | A defined manufacturing process must take place in the country of origin (e.g. spinning, weaving, chemical reaction) | Textiles, clothing, pharmaceuticals, steel |
| Wholly got (WO) | No non-originating materials used at all | Agricultural goods, minerals, fish |
| Combination rules | Product must meet two or more criteria simultaneously | Complex manufactured goods, some chemicals |
Under the TCA, each product category has its own rule set out in Annex ORIG-2. You look up the commodity code for your product and find the relevant rule. Then you assess whether your manufacturing process meets it.
The UK-EU Trade and Cooperation Agreement came into force on 1 January 2021. It provides for zero tariffs on goods that meet the agreement’s rules of origin. This is what sets the TCA apart from a standard WTO trading relationship. It also makes compliance essential.
The TCA uses product-specific rules (PSRs), set out in Annex ORIG-2 of the agreement. Each product category, identified by its HS commodity code, has its own origin rule. There is no single rule that applies to everything.
Some examples of how product-specific rules work under the TCA:
To check which rule applies to your product, use the UK’s online trade tariff at trade-tariff.service.gov.uk. You can also consult the TCA text directly. HMRC also publishes guidance notes on claiming preference under the TCA.
The TCA rules are product-specific but symmetrical. The same standard applies in both directions. UK exporters claiming EU preference face the same rules as EU exporters claiming UK preference.
Cumulation is one of the most useful concepts in rules of origin. It is also one of the least well understood.
Under normal rules of origin, only materials and processing from the claiming country count toward the origin test. Materials from anywhere else are treated as non-originating, even if they came from a close trading partner.
Cumulation changes this. It allows materials and processing from certain partner countries to be counted as originating for the rules of origin test.
The TCA provides for bilateral cumulation between the UK and the EU. This means:
Why does this matter in practice?
Suppose a UK electronics manufacturer sources components from Germany. Those German components have EU origin. Under bilateral cumulation, the UK manufacturer can count those EU components as originating materials. This matters when working out whether their finished product meets the TCA’s value-added threshold.
Without cumulation, those German components would be treated as non-originating. That could push the product over the maximum non-originating content limit and disqualify it from TCA preference.
Cumulation does not mean you can use materials from anywhere in the world and claim UK origin. It applies only to materials with confirmed EU origin, or the origin of whichever cumulation partner applies.
Claiming preferential tariff treatment under the TCA, or any other free trade agreement, requires documents as evidence. Customs authorities need proof that your goods genuinely qualify as originating.
There are three main documents used in the UK-EU context.
Supplier Declarations
A supplier declaration confirms the origin of goods or materials from a supplier. If you buy components or materials from a supplier, you will often need a supplier declaration from them. This supports your own origin claims.
Supplier declarations should state whether the goods are originating or non-originating. If originating, they must state which country’s origin they carry.
Statement on Origin
For TCA exports to the EU, the exporter places a statement on origin on the commercial invoice. Another commercial document can also be used. This replaced the older EUR1 movement certificate for UK-EU trade.
The statement on origin uses a specific declaration in prescribed wording. HMRC publishes the exact text that must be used. The exporter takes responsibility for its accuracy.
For consignments above £6,000, the exporter needs REX status or HMRC approval to make the statement. Below £6,000, any exporter can make the statement without REX registration.
Long-Term Supplier Declarations
Where a supplier regularly provides identical goods with the same origin, they can use a long-term supplier declaration. This covers all supplies over a defined period, typically up to two years. This avoids the need for a declaration on every individual invoice.
Long-term declarations must be reissued if the product or process changes in a way that could affect origin.
Rules of origin are not just a compliance issue at the point of export. They have practical implications for how you structure your supply chain and how you cost your products.
Know your inputs. You need to know where every major material or component in your product comes from. If your supplier sources from multiple countries, you need supplier declarations confirming the origin of what they send you.
Check the product-specific rule before signing contracts. If you are sourcing new components from a non-UK, non-EU supplier, check whether using those components will affect your product’s ability to claim TCA preference. The decision to source from a particular country can have origin consequences you need to factor in before you commit.
Keep records. HMRC expects exporters to be able to show origin on request. Retain supplier declarations, bills of materials, manufacturing records, and import documents for at least four years.
Review regularly. If your product formulation, manufacturing process, or supply chain changes, your origin status may change too. A product that qualified as UK origin last year may not qualify this year if you switched to a cheaper non-EU supplier for a key component.
Warn your customers. If you are not certain your goods qualify for preference, do not encourage customers to claim it. An incorrect preference claim creates a customs debt that normally falls on the importer of record, your customer.
These are the errors that come up most often in practice. They are the ones most likely to cause problems down the line.
Assuming country of dispatch equals country of origin. Goods shipped from Germany are not necessarily of German origin. Always verify origin through supplier declarations. Do not assume.
Not getting supplier declarations. Many UK manufacturers rely on inputs from overseas suppliers but never ask for supplier declarations. Without these, they cannot show the origin of their materials and cannot support their own origin claims.
Confusing “Made in UK” marketing with preferential origin. A product labelled “Made in the UK” for marketing purposes may not qualify as UK origin under the TCA’s product-specific rules. The marketing standard and the trade policy standard are different things.
Applying the wrong product-specific rule. The TCA has hundreds of product-specific rules. Using the wrong HS code means you look up the wrong rule. Always start from the correct ten-digit commodity code.
Missing the REX registration requirement. For consignments above £6,000, you need REX registration to make a statement on origin. Exporters who make statements without the required approval are making invalid declarations.
Failing to renew long-term supplier declarations. Long-term declarations expire. Exporters who rely on outdated declarations are making origin claims they cannot support.
Not considering cumulation. Some UK exporters disqualify themselves unnecessarily by treating EU-origin inputs as non-originating. Bilateral cumulation under the TCA allows EU materials to count as originating when working out TCA preference eligibility.
Before Brexit, UK businesses trading with the EU did not need to think about rules of origin. As EU members, goods moved freely without origin checks or duty assessments. That changed on 1 January 2021.
The TCA introduced zero tariffs on UK-EU trade, but with conditions attached. Those conditions are the rules of origin.
For many UK manufacturers, this created a real problem. UK supply chains were built on the assumption of frictionless EU trade. Components were routinely sourced from across the EU and incorporated into UK products. Post-Brexit, too many non-originating inputs from outside the EU could push a product outside TCA origin rules.
The most affected sectors have been:
Some manufacturers have restructured supply chains to source from UK or EU suppliers instead of lower-cost alternatives. This keeps their products within TCA preference rules. Others have accepted their products do not qualify, priced accordingly, or absorbed the duty cost to stay competitive.
The key point for UK exporters: TCA zero duty is available, but it is not automatic. Your goods must genuinely originate in the UK under the relevant product-specific rule. If they do not, standard EU import duty applies.
The scenario: A UK clothing manufacturer based in Leicester makes men’s cotton chinos. The commodity code is 6203 42 31 10. They export to a retailer in France and want to claim TCA preference: zero import duty on entry into the EU.
Step 1: Find the product-specific rule.
Under TCA Annex ORIG-2, the rule for men’s trousers (HS heading 6203) requires manufacture from yarn. In practice, the fabric must have been produced in the UK or the EU. This is a fabric-forward rule. Simply cutting and sewing imported fabric in the UK is not enough.
Step 2: Assess the supply chain.
The manufacturer sources cotton fabric from a mill in Turkey. Turkey is not the UK or the EU. The fabric is non-originating. The rule requires fabric produced in the UK or EU, woven from UK- or EU-spun yarn. Fabric from Turkey does not meet this requirement.
Step 3: Can cumulation help?
Bilateral cumulation under the TCA applies to UK and EU inputs only. Turkish fabric is neither UK nor EU origin, so cumulation does not help here.
Step 4: Outcome without a supply chain change.
The product does not qualify as UK origin under the TCA product-specific rule. If the French retailer claims TCA preference at import, the claim is invalid. HMRC and French customs authorities can demand repayment of the duty that should have been paid. This may come with interest and penalties.
Step 5: The fix.
The manufacturer has two options. They can source fabric from a UK or EU weaver, ensuring the fabric itself has the right origin. Or they can price without TCA preference and warn their customer that standard EU import duty will apply. Either approach is legitimate. What they cannot do is make an origin declaration they know to be incorrect.
The lesson: Rules of origin must be verified against the actual supply chain. The product-specific rule for clothing is demanding. Assumptions about “made in the UK” do not substitute for a proper origin assessment.
What is the difference between country of origin and country of export?
Country of export is where the goods were shipped from. Country of origin is where the goods were produced or last substantially transformed. A product shipped from a UK distribution centre might have been manufactured in China. Its origin is China, not the UK.
Do I need to declare origin on every export shipment?
You only need an origin declaration if your customer wants to claim preferential duty treatment at import. If they do not claim preference, no origin statement is needed. That may be because the product fails to qualify or because duty is low anyway. You must never make an origin statement you know to be incorrect.
What happens if my goods do not qualify as UK origin under the TCA?
Your EU customer will pay the standard MFN duty rate when the goods enter the EU. This is often 6–12% for manufactured goods. Warn customers in advance so they can budget for it. If a preference claim was wrong, the importer may face a demand for unpaid duty from EU customs.
What is a REX number and do I need one?
REX stands for Registered Exporter. It is a registration with HMRC that lets you make origin statements for consignments above £6,000 in value. You apply through HMRC’s online service. For shipments below £6,000, any exporter can make the statement without REX registration.
Can I use the same rules of origin documentation for all trade agreements?
No. Each trade agreement has its own rules and its own approved documents. The TCA statement on origin differs from the paperwork used under UK-Canada or UK-Japan trade agreements. Always check which document is required for the specific agreement you are relying on.
How long do I need to keep rules of origin records?
HMRC recommends keeping all supporting records for at least four years from the date of export. This includes supplier declarations, bills of materials, manufacturing records, and import documents. Some trade agreements require longer retention periods.
What is the difference between a supplier declaration and a statement on origin?
A supplier declaration is made by a materials or components supplier to their customer (the manufacturer or exporter). It confirms the origin status of the materials supplied. A statement on origin is made by the exporter to the importer. It confirms the finished goods meet the origin requirements of the trade agreement being used. They are different documents serving different purposes in the same chain of evidence.
My goods are assembled in the UK from imported parts. Are they UK origin?
It depends on whether the assembly process meets the product-specific rule for your commodity code. Simple assembly, putting together pre-made components, often does not count as enough processing. A tariff classification change or value-added test may still need to be met. Look up the specific rule for your product before making any claims.
Rules of origin determine the “economic nationality” of goods: which country they genuinely come from for trade purposes. Country of origin is not the same as country of shipment.
There are two types: preferential origin (for claiming duty savings under a trade agreement) and non-preferential origin (for anti-dumping, sanctions, trade statistics, and other measures). Most UK exporters to the EU are mainly concerned with preferential origin under the TCA.
The two main tests for preferential origin are wholly got (the entire product came from one country, mainly for natural goods) and enough processing (the product was made from imported materials that were transformed enough to confer origin).
enough processing is assessed using three main criteria: tariff classification change, value added threshold, and specific process requirements. Which one applies depends on the product’s commodity code.
Under the TCA, each product category has its own product-specific rule set out in Annex ORIG-2. There is no single rule for everything. You must look up the rule for your specific commodity code.
Bilateral cumulation under the TCA means that EU-origin materials used in UK production can count as originating. This is an important tool for UK manufacturers who source from EU suppliers.
Claiming TCA preference requires documents as evidence, mainly a statement on origin on the commercial invoice. For consignments above £6,000, you must be a Registered Exporter (REX) registered with HMRC.
Post-Brexit, UK manufacturers exporting to the EU must prove UK origin to benefit from zero tariffs. Goods made substantially from non-UK, non-EU inputs often fail the product-specific rules, especially in textiles, automotive, and food.
Keep supplier declarations, bills of materials, and manufacturing records for at least four years. HMRC can request evidence of origin at any time.
If you are not certain your goods qualify as UK origin, do not make an origin declaration. An incorrect preference claim creates a customs debt, usually falling on your customer as the EU importer of record.
