UL Listed, Recognized and Classified Marks Guide
Distinguish UL product and component certification marks, check the complete model and certification record, and document the scope before relying on a label.

Distinguish certification scopes
Read the complete certification marking and the associated product information. A familiar logo alone does not tell you which product, country, characteristic or use the certification covers. This reference focuses on selected UL mark families used in North America; it is not an exhaustive directory of certification organizations.
| Scope | What to look for | What not to infer |
|---|---|---|
| Listed product | The exact product identity, applicable certification category and stated use conditions | Approval of every installation, field modification or combination with another product. |
| Recognized Component | A component intended for use within an evaluated end product or system, with applicable conditions of acceptability | A complete stand-alone product Listing or unrestricted field substitution. |
| Classified product | The particular properties, hazards, standards or conditions covered by the Classification | Evaluation of every characteristic or every possible replacement application. |
| Enhanced or combined marking | The complete identifier, country indicators, attributes and available record information | That one graphic layout describes all certification programs in the same way. |
UL provides different mark formats and country indicators. Use its current mark explanations and the matching certification record to interpret the label; do not reconstruct an approval from a seller's icon or a partial photograph. This page intentionally uses text descriptions rather than imitations of certification logos.
Find the matching record
- Photograph or transcribe the manufacturer's name, complete model/catalog number, mark, identifying file or other record information, ratings and label location.
- Use the certification organization's official search route. For UL, start with Product iQ and its search guidance; access requirements and available record detail can vary.
- Match the complete manufacturer and model or documented model series. Similar names and a shared enclosure shape are not a match.
- Read the category, country scope, stated standards and the information applicable to that product. Retain referenced limitations or installation instructions.
- Resolve an ambiguous model, missing record, suspect label or conflict with the manufacturer or certification organization. A failed search is unresolved information, not proof of approval or proof of counterfeit.
If the record points to a component, keep the component conditions separate from the evaluation of the complete assembly. If it covers a replacement product, read the specific compatibility information rather than assuming every product of the same current rating is included.
Document the result
| Field | Useful record | Reason |
|---|---|---|
| Product | Manufacturer, complete model, revision and equipment location | Connects the search result to the actual item. |
| Mark and identifier | Full label photo and searchable identifying information | Avoids relying on a cropped logo. |
| Record | Official record link or document reference and date accessed | Makes the basis retrievable. |
| Scope | Product/category, countries, ratings and documented limitations | Shows what was actually established. |
| Application review | Equipment instructions, approval reference and unresolved questions | Keeps installation suitability separate from mark recognition. |
The record can accompany the job card. Record the information actually found; leave unknown conditions explicitly unresolved rather than filling them with an assumed equivalent.
Check the whole application
Certification scope, product ratings, equipment compatibility and installation requirements are different checks. An authentic mark does not by itself approve a mixed-brand panel arrangement, a modified assembly, a terminal conductor combination or a particular environment.
Use the breaker marking and compatibility guide for panel-specific questions, terminal markings for connection conditions, and code-adoption guidance for the project rules. The SCCR comparison tool only compares the ratings and fault-current data entered; it does not perform a certification review.
