SI 2019/696
For manufacturers selling into Great Britain working out when products need the UKCA mark and what goes with it. This page covers what you need to know and ways to avoid running into issues.
What we've seen reported
UKCA marking, introduced by SI 2019/696, is the conformity marking for regulated products placed on the market in Great Britain; UK government guidance says the CE marking is also recognized there for most of them.1,2

What the rules cover
These are the kinds of product information UKCA marking involves, according to the regulations and the UK government's guidance for Great Britain.1,2
| Requirement | Where it applies |
|---|---|
| A conformity marking | UKCA, or the CE marking under continued recognition, for products in the UKCA and CE regimes. |
| Where the marking goes | On the product; for UKCA, a label or accompanying document is allowed until December 31, 2027. |
| Manufacturer's name and postal address | Manufacturers: on the product, or on packaging or an accompanying document where the legislation allows. |
| Importer's name and postal address | Importers: on the product; for EEA imports, on packaging or a document until December 31, 2027. |
| Type, batch, serial or model number | As set out in the product regulations for each sector. |
| Instructions | Accompanying the product, in easily understandable English. |
| Declaration of conformity | A UK or EU declaration, drawn up by the manufacturer and kept, typically for 10 years. |
Where it goes wrong
One approved set of product information ends up in many channels, markets and languages. Along the way it gets shortened, translated and reworded, and some versions end up without the warnings or details these rules require.

FAQ
On more than the product. UK government guidance describes markings and contact details on the product, its packaging or accompanying documents,2 and for most businesses that means:
Treat each market's label set as approved content with its own version, not a copy of the EU one. When an address, importer or declaration changes, every pack, manual and listing that carries it needs the same change, including stock already printed. Our packaging compliance page shows how teams track this.
Check that each listing and retailer feed carries the details the pack carries: the marking, the manufacturer and importer contact details, and the instructions in English. Marketplace templates often have no field for an importer address, so that is where it tends to go missing. Retailer feeds built from EU data are the other common gap, because they carry the EU importer instead of the GB one.
How it applies to a specific listing is a question for your legal adviser. Where that listing appears across your markets and languages is a question Arbitr answers.
Regulatory and product compliance usually own the marking, but packaging, e-commerce, documentation and retail teams publish it, and importers and distributors repeat it. Food labeling rules such as Natasha's Law sit alongside it, and related rules are on our product labeling hub.
They're used in different markets. UK government guidance describes UKCA for Great Britain, and CE or CE with UKNI for products placed on the market in Northern Ireland.2
At 11pm on December 31, 2027, according to UK government guidance, which describes legislation allowing the UKCA marking on a label or accompanying document until then.2
Arbitr checks your content against the rules, claims and terms your team has approved, and reports where something doesn't match, by channel, market and language. It reports matches against your rules, not legal verdicts. What to do with each one stays with your team.
