UL Listed

What it is

The UL Mark (UL Listed / UL Certified) is the primary North American safety certification for electrical and many consumer products, issued by UL Solutions after testing against UL safety standards.

What it covers

Electrical safety, fire safety, and structural/mechanical safety for powered nursery gear (monitors, humidifiers, warmers), home appliances, and air-quality devices.

How to verify

Enhanced UL Marks carry a unique identifier resolving to ul.com/database, which lands on UL's Product iQ certification database. Lookup is free but requires a one-time registration.

How SafeMama uses it

UL Listed status is the baseline safety expectation for anything with a plug or battery in SafeMama's guides — named in text with a pointer to Product iQ. It is kept clearly distinct from UL GREENGUARD Gold, which covers chemical emissions and has its own registry record.

Limitations / conflicts

UL Solutions is a for-profit certifier. Product iQ's registration gate means no anonymous programmatic verification, and UL's third-party mark-usage guidance is currently unverifiable by quote (moved to a JavaScript-only page) — flagged for a browser-based read.
