CE marking vs UL listing, step by step: what a US manufacturer has to do before a European distributor will stock the product

A European distributor that receives a UL-listed product from a US manufacturer usually asks first: where is the EU declaration of conformity? The UL mark says a respected lab tested the product to a US standard. It does not answer what the distributor is legally required to check under EU law.

Our compliance checklist lists the topics to cover before the first meeting. This post goes deeper into the first two, CE marking and the EU responsible operator, step by step for a typical industrial or electrical product.

Putting it simply: UL is a private lab that certifies your product and keeps inspecting your factory. CE marking is your own legal declaration that the product meets every EU act that applies to it; a third party (a Notified Body) is required only for certain products and procedures. You need EU standards, a technical file, a signed declaration, an operator established in the EU and documents in the buyer's language. Your UL work helps but replaces none of these.

Two different ideas of "approved"

In the US, OSHA requires workplace electrical equipment to be "approved" (29 CFR 1910.303(a)), which under 1910.399 mainly means listed, labeled or certified by a nationally recognized testing laboratory. OSHA's NRTL program "recognizes private sector organizations to perform certification"; UL LLC is one of 21 labs on the current list, alongside Intertek, TÜV Rheinland and TÜV SÜD. The lab certifies, the manufacturer applies the lab's mark, and UL says it continues "to check products months and years after testing."

The EU works the other way round. Under Article 30 of Regulation (EC) No 765/2008, only the manufacturer or its authorized representative affixes the CE marking, and in doing so the manufacturer "takes responsibility for the conformity of the product." The Commission's Blue Guide asks whether all CE-marked products are tested and approved by authorities: "No." Conformity is "the sole responsibility of the manufacturer"; only high-risk products need a Notified Body.

We do not quote prices or lead times: neither UL's terms nor the EU acts publish them, and they depend on the product. Ask a test lab or Notified Body for a quote.

Step 1: Find every EU act that applies

A typical US industrial product sits under several acts at once:

• Machinery Regulation (EU) 2023/1230 replaces the Machinery Directive 2006/42/EC and, per the Commission, "applies on a mandatory basis as of 20 January 2027" (the original Official Journal text said January 14). For machines, electrical risks are assessed "solely" under the machinery rules, which take over the Low Voltage Directive's safety objectives (Annex III, 1.5.1).
• Low Voltage Directive 2014/35/EU, for equipment rated 50–1,000 V AC or 75–1,500 V DC. The Machinery Regulation excludes "low-voltage switchgear and control gear" and electric motors insofar as the Low Voltage or Radio Equipment Directive covers them (Article 2(2)(p)), so a stand-alone control panel is usually an LVD product while the machine it goes into is machinery.
• EMC Directive 2014/30/EU, electromagnetic compatibility.
• RoHS Directive 2011/65/EU, restricted substances; check its exclusions (such as "large-scale stationary industrial tools") rather than assume them.
• Radio Equipment Directive 2014/53/EU if there is any radio, even Wi-Fi or Bluetooth. It covers safety "with no voltage limit applying" and EMC (Article 3(1)), and since August 1, 2025, cybersecurity for internet-connected equipment (Delegated Regulation (EU) 2022/30, as amended by (EU) 2023/2444).

The hard case: medical devices. Under Regulation (EU) 2017/745 only Class I devices are self-declared, and even they need a Notified Body for sterile, measuring or reusable-surgical aspects; Classes IIa, IIb and III always do (Article 52). A non-EU manufacturer must designate a "sole authorised representative" (Article 11). Budget far more time.

Step 2: Map your US standards to EU harmonized standards

Meeting harmonized standards published in the Official Journal gives a presumption of conformity (Decision 768/2008, R8; LVD Article 12). They are voluntary, but if you use something else the Blue Guide says you "carry the burden" of proof.

Under the Machinery Directive, the electrical standard for machines is EN 60204-1:2018, listed in Implementing Decision (EU) 2023/1586 as "IEC 60204-1:2016, modified." A US machine is usually wired to NFPA 79, with the panel built to UL 508A. These are related documents, but neither is the EN standard, and passing UL 508A does not show conformity with EN 60204-1. Plan a clause-by-clause gap analysis and retest where requirements differ. As of October 24, 2026 we have not checked which references under the new Machinery Regulation cover a given machine; confirm the current list with your test lab.

For RED cybersecurity, EN 18031-1, -2 and -3:2024 were published "with restrictions" (Implementing Decision (EU) 2025/138): for example, no presumption of conformity if the user may skip setting a password.

Step 3: Choose the conformity assessment module

Decision 768/2008, Annex II, sets the menu; each act picks from it:

LVD and RoHS: module A. EMC: A or B+C. RED: A for spectrum and cybersecurity only if harmonized standards are applied in full, otherwise B+C or H. Machinery: B+C, H or G for Annex I Part A (now including safety components with "self-evolving behaviour using machine learning approaches"); Part B machines such as certain woodworking saws may use A only if fully built to the specific harmonized standards; all other machinery uses A (Article 25). You may choose "any notified body" designated for the procedure (Blue Guide); they are listed in the Commission's NANDO database.

Step 4: Build the technical file and sign the declaration

Under module A, the file includes a product description, drawings and circuit diagrams, "an adequate analysis and assessment of the risk(s)," the standards applied, calculations and test reports, kept for 10 years.

The declaration follows Annex III of Decision 768/2008: unique product identification, your name and address, a statement that it is issued "under the sole responsibility of the manufacturer," the EU acts and standards, any Notified Body and certificate, and a signature with place, date, name and function. Several acts mean one declaration (EMC Article 15(3); Machinery Regulation Article 21(3)).

The Blue Guide confirms the signatory need not be "domiciled in the European Union"; the guide names "the Managing Director of the company or another representative of the company to whom this responsibility has been delegated" as the signatory. The declaration is translated into the language the member state requires, with the signed original attached to any translation made by others. From January 2027, machinery may ship with a link or machine-readable code to the declaration instead (Article 10(8)).

Step 5: Decide who answers for the product in the EU

Article 4 of Regulation (EU) 2019/1020 covers machinery, LVD, EMC, RoHS and RED products, among others: such a product "may be placed on the market only if there is an economic operator established in the Union" responsible for it, whether an EU manufacturer, the importer, an authorized representative with a written mandate or a fulfillment service provider. Its name and postal address go on the product, packaging, parcel or an accompanying document.

If your distributor buys from you and brings the goods in, it is the importer: it must check your assessment and file before placing the product on the market, and adds its own name (R4). If it sells under its own brand, it becomes the manufacturer in law (R6). Put the roles in writing; our route comparison shows how they shift with a subsidiary or online sales.

Step 6: Affix the mark correctly

At least 5 mm high unless an act says otherwise (Reg. 765/2008, Annex II), "visibly, legibly and indelibly" on the product or data plate, before placing on the market, followed by the Notified Body's number where it is involved in production control (R12). Your UL mark can stay, provided it does not impair the CE marking's "visibility, legibility and meaning"; marks "likely to mislead" are prohibited (Article 30(5)).

What the distributor will check

Under R5, a distributor must verify the CE marking, the required documents, instructions and safety information "in a language which can be easily understood" in its country, and the manufacturer's and importer's names and addresses. If it has reason to believe the product does not conform, it must not sell it. That is why it asks.

What this means for a US manufacturer

Your UL file is a head start: its test reports, construction details and quality records feed the EU technical file. But the EU decision is yours to make and sign. Work through step 1 per product line, budget for the EN gap analysis, and settle your EU operator early. Send your first sample with the signed declaration, the manual in the target language (German for Germany, for example) and a label proof showing both addresses.
