If you are importing LED strip into the United States, the paperwork question you will be asked is not “does it have CE” — it is “what is the UL file number”. Getting this wrong is expensive: material held at customs, an inspector refusing to sign off, or a retailer refusing delivery. This article explains what the marks actually mean, so you can ask suppliers the right question.
Three marks that are not the same thing
| Mark | Meaning | Applies to |
|---|---|---|
| UL Listed | Complete product tested as a finished item | End products — luminaires, signs, power supplies |
| UL Recognized Component | Component tested for use inside another product | LED modules, drivers, wiring — the RU mark |
| ETL / Intertek | NRTL listing to the same standards as UL | Functionally equivalent for code compliance |
The distinction matters because a bare strip is a component, not an end product. A supplier who says “our strip is UL listed” and then produces a Recognized Component certificate is not lying — but the strip cannot be sold as a finished luminaire on that basis, and the sign builder still needs the assembly to be evaluated.
Which standard covers what
- UL 8750 — the base standard for LED equipment used in lighting products. This is the one most LED modules and strips are evaluated against
- UL 2108 — low-voltage lighting systems, which is where many strip plus driver assemblies land
- UL 1598 — luminaires generally, relevant when the strip is supplied in a housing or profile as a fixture
- UL 48 — electric signs, the standard that applies to a finished neon flex or channel letter sign
- UL 1310 — Class 2 power units, covering the driver
- UL 746C — polymeric materials, relevant to the silicone or PVC jacket outdoors
Note how many standards sit around a single product. A complete strip system may involve the module, the driver, the wiring and the housing being evaluated separately, then the assembly being reviewed as a whole. That is why the file number matters more than the logo.
What an inspector actually checks
The inspector looks up the file number — an E-number such as E123456 — on UL Product iQ, and checks that the model on the label appears in that file’s construction data. A certificate PDF with no file number is unusable for this purpose, and a file number that exists but does not list your model is worse than none, because it looks valid until it is checked.
Ask for the file number, then look it up yourself before you buy. It takes two minutes and it is free.
CE is not a substitute, and CE is not a certificate
CE marking is a self-declaration by the manufacturer that the product meets the applicable directives — the Low Voltage Directive, EMC, RoHS and the ErP ecodesign rules. There is no central EU body that issues a CE certificate, which means any document titled “CE Certificate” is either a test report from a notified body or a piece of paper with a logo on it.
For EU projects the useful documents are: the declaration of conformity, the test reports behind it, and the specific harmonised standards applied — EN 62031 for LED modules, EN 60598-1 for the luminaire, EN 61347 for the driver.
Red flags in supplier documentation
- A certificate with no file number and no model list
- A report that tests a different model number from the one you are ordering
- “CE” and “RoHS” shown as a single combined certificate with no test data
- A certificate issued in a name that does not match the manufacturer or its trading entity
- Photographs of a label rather than the certificate itself
What to request, in order
- UL file number (E-number) for the exact model, and permission to look it up
- The Recognized Component certificate, checked for your model in the construction data
- For EU: declaration of conformity plus the underlying test reports
- FCC Part 15 report for anything containing a switching driver
- RoHS test report naming the exact part
We supply LED strip and neon flex with documentation for the exact model you order, and we will tell you upfront which standards a given product is and is not evaluated against — it is faster than finding out at the port. Send us the model numbers you are considering and the destination market, and we will return the document set for each.
