# CE vs UKCA marking: what you need to sell in the UK after Brexit
If you import goods into the UK, the CE vs UKCA marking question comes up fast. Suppliers in China ask which mark you want on the product. Your forwarder mentions it on the paperwork. And getting it wrong can hold up a shipment or force a relabel on your side of the ocean, at your cost.
Here is the short version. CE is the conformity mark used across the European Union. UKCA is the UK's own mark, created for goods placed on the market in Great Britain after Brexit. And for most product categories, the UK accepts CE marking indefinitely, which settles the CE vs UKCA marking question for most importers before it really starts. This guide walks through what each mark covers, where the two actually differ, and what to do about them when you place an order.
One warning before we go further. Product rules move, and the list of categories where CE is accepted in the UK can change. Use this article as the framework, then check the current UK government guidance for your product before you commit to a purchase order.
What CE marking actually covers
CE marking is the EU's way of saying a product meets the requirements of the directives that apply to it. The directives importers run into most often are the Low Voltage Directive for electrical equipment, the EMC directive for electromagnetic compatibility, the Toy Safety directive, and the Machinery directive. Sitting alongside those are RoHS, which restricts hazardous substances in electronics, and REACH, which governs chemicals across many product types.
How a product earns the mark depends on the directive and the risk class. Low-risk products can go through self-declaration. The manufacturer assembles a technical file, signs a declaration of conformity, and affixes the mark. Higher-risk products need a notified body, an independent organisation designated under the relevant directive, to carry out the assessment. When a notified body is involved, its number appears next to the CE mark on the product itself.
This matters when you source from China because a supplier offering "CE certification" might be showing you any one of three very different things: a self-declaration, a test report from an unknown lab, or a genuine notified-body certificate. The price of the goods often reflects which one you are actually getting. A test report from a lab nobody has heard of does not carry the same weight as an assessment by a body listed in the EU's NANDO database, and a self-declaration is only as good as the technical file behind it. When a quote looks surprisingly cheap for a regulated product, the conformity paperwork is one of the first places to look. Suppliers sometimes treat the CE vs UKCA marking choice as a simple either-or, but the real work is confirming what the CE mark on your goods actually certifies before comparing it to anything else.
What UKCA marking is
UKCA stands for UK Conformity Assessed. It is the UK's domestic product marking for goods placed on the market in Great Britain, created so the UK would have its own conformity route outside the EU system. In structure it mirrors CE closely. The product has to meet the relevant UK regulations, the manufacturer holds a technical file and a declaration of conformity, and higher-risk products need assessment by a UK-recognised body rather than an EU notified body.
For an importer, the history is less important than the present question: which mark do your goods need on the day they arrive at the UK border? Because the two systems mirror each other, the CE vs UKCA marking comparison comes down less to technical differences and more to which market accepts which paperwork.
CE vs UKCA marking: the practical comparison
This is where the CE vs UKCA marking debate usually resolves itself. The UK government accepts CE marking indefinitely for most product categories. CE-marked goods keep moving into the UK without needing the UKCA mark added. For most importers, CE remains the practical standard for both the EU and UK markets, and the decision is simpler than the two acronyms make it look.
Work through it as a short decision tree. If you sell only in the UK and your category is one where CE is accepted, CE alone does the job. If you sell in both the UK and the EU, CE covers both markets, and adding UKCA buys you nothing in most categories. Most of the CE vs UKCA marking anxiety importers feel comes from treating the two marks as rivals. Strip away the acronyms and the decision is a paperwork question, not an engineering one: which documents does your market accept today? UKCA starts to matter where the UK does not accept CE for your category, or where UK regulations have diverged from their EU equivalents and you want the domestic route documented.
The real differences, where they exist, are procedural rather than philosophical. A product carrying UKCA needs its third-party assessment from a UK-recognised body where assessment applies; an EU notified body number does not substitute. The declaration of conformity references UK regulations instead of EU directives. Where the CE vs UKCA marking rules leave room for doubt on any of these points, a quick check of the current official guidance costs nothing and settles it. The mark itself is different, with its own rules on size, proportions, and placement. None of this changes the underlying point for most categories: one mark, CE, continues to serve both markets.
Before you order, pin down three things. First, which product category your goods fall into, because acceptance of CE in the UK is category-dependent and this is the step people skip. Second, whether your product can be self-declared or needs third-party assessment, since that decides both cost and timeline. Third, what your supplier's "CE certificate" actually is. Ask for the document, check any notified body number in the NANDO database, and confirm the certificate names the legal entity you are paying. A certificate in someone else's company name proves nothing about your supplier.
What the CE vs UKCA marking rules mean for your sourcing
Start with the product, not the mark. Classify what you are importing, confirm which UK and EU rules apply to that category, and check the current official guidance on whether CE is accepted for it. Settling the CE vs UKCA marking question before you request quotes also protects your pricing, because the conformity route affects what the supplier charges. Do this before you ask the supplier for a quote, because the conformity route affects the price. Third-party assessment costs money and takes time, and a supplier quoting "CE included" may mean anything from a genuine assessment to a sticker applied in the packing room.
Then verify instead of trusting. Pull the supplier's business license and check it against the certificate. The legal entity named on the certificate has to match the company receiving your payment, or the paperwork is decoration. Get the CE vs UKCA marking answer in writing from your supplier before production starts, as part of the spec sheet, not as an afterthought at packing time. Mismatched names are the most common way traders pose as factories. Check notified body numbers in NANDO rather than taking a PDF at face value. Keep the technical file and the declaration of conformity on record. If customs or a marketplace asks for proof, those documents are what you produce, not the mark printed on the box.
Watch for one common sales tactic. If a supplier or their lab pushes UKCA testing for a category where CE is accepted in the UK, ask what problem the extra testing solves. Sometimes there is a legitimate reason, such as a specific buyer requirement. Often it is just the lab selling an additional service. The CE vs UKCA marking question should be answered by your product category and your markets, not by whoever quotes the testing.
Build the marking into your quality control as well. The sample that passed testing and the goods that ship six weeks later are not automatically the same product. A changed component, a substituted material, or a different sub-supplier can all invalidate the conformity the certificate describes. Your QC checklist should tie the shipped goods back to the certified configuration, and any material change should trigger a conversation about retesting before the goods leave the factory.
Mistakes importers make with UK product marking
The most expensive mistake is treating the mark as proof of compliance. A CE mark on the product means the manufacturer claims conformity. It does not mean anyone independent checked. Importers who learn this at the border, when a shipment is held for documentation they cannot produce, pay for the lesson in storage fees and delays.
The second mistake is ordering to the wrong market's rules. That happens when goods bound only for the UK get certified to a route the UK does not require, wasting money, or when goods bound for both markets get certified for one and held up in the other. Map your markets before you map your marks.
The third is paperwork drift across repeat orders. The first shipment was tested and properly documented. By the third, the factory has quietly changed a component supplier and nobody retested. A fourth mistake, specific to the CE vs UKCA marking topic, is paying for both marks out of caution without checking whether the second one was ever required. Retest on a cadence for repeat orders, especially when anything in the bill of materials changes.
Conclusion
The CE vs UKCA marking question looks complicated from a distance and turns out to be a short checklist up close. Confirm your product category. Check whether CE is accepted for it in the UK under current official guidance. Verify that the supplier's certificate names the company you are paying, and that any notified body number checks out in NANDO. Keep the technical documentation on file. Do those things and the marking on the box becomes the least interesting part of the shipment, which is exactly how it should be.
FAQ
### Do I need UKCA marking if my product already has CE marking?
For most categories, no. The UK accepts CE marking indefinitely for most product categories, so CE-marked goods can be placed on the UK market without UKCA. That is the whole CE vs UKCA marking question in one sentence: which paperwork does your market accept today? Check the current official guidance for your specific category, since acceptance is category-dependent.
### Can a product carry both CE and UKCA marks?
Yes, where each mark is validly earned. Products sold in both markets can carry both. For most categories CE alone covers the EU and the UK, so the double mark is usually unnecessary rather than wrong.
### Who carries the risk if the marking turns out to be fake?
You do, as the importer placing the goods on the market. That is why verification matters more than the mark itself: check the certificate, check the notified body number, and confirm the named legal entity matches your supplier.
### My supplier says UKCA testing is required. Should I pay for it?
Not before you check. Confirm whether your category is one where the UK accepts CE marking. If it is, ask the supplier what the UKCA testing adds. Pay for assessment you need, not assessment you were sold.
