Which products are UL and ETL certified?
What is UL?
UL stands for Underwriters Laboratories , an independent organization that sets and tests safety standards for products across the industry. UL is known for its standards for electrical products, such as light bulbs, lamps, and sockets, which often bear the UL symbol or "UL Listed."
What is ETL certification?
ETL stands for Electrical Testing Laboratories, a certification division of Intertek Testing Laboratories . Intertek is a member of OSHA's Nationally Recognized Testing Laboratories (NRTL ) program, and ETL's safety standards conform to those established by that program.

UL and ETL Listed
UL Listing: The UL Mark is divided into three categories: Listed, Classified, and Recognized Component. The Listed mark means that a product with a specific function has been tested according to nationally recognized UL standards for that type of equipment. The UL Mark with "C" and "US" in the image below means it is certified for both Canada and the U.S.
ETL Listed: This is a flexible security certification brand that is growing rapidly in North America. ETL Listed is the most adaptable certification currently awarded by Intertek. While the certification process is similar to that of traditional ETL certification, ETL Listed is specifically designed for the U.S. and Canadian markets. Thanks to its strict security laws, this certification is recognized in many other international markets.
Which is more efficient, UL or ETL certification?
UL certification takes longer due to its broader recognition and acceptance, resulting in a backlog of products pending certification. Some companies face the dilemma of maintaining production schedules while waiting several months for safety certification, resulting in a significant buildup of inventory and delaying their market entry.
In contrast, the ETL certification process is typically faster. However, some believe that, despite using UL standards, ETL certification may not be as rigorous as UL.
What is more expensive, UL or ETL certification?
The costs of UL and ETL certifications include initial testing fees, ongoing service fees, qualification fees, and other expenses. In general, UL certification is usually more expensive than ETL certification. In certain categories, the cost of ETL certification can even be half that of UL.
It's important to keep in mind that these certifications require a considerable investment of time and money. If the product needs to be modified after the review, restarting the entire process can be costly.
Therefore, ETL certification is sometimes more popular in terms of efficiency and cost.
Which products are UL and ETL certified?
UL certification covers a broader range of fields, while ETL certification focuses on the electronics industry. The main difference is that UL sets its own safety standards, while ETL certification adopts standards from other laboratories, including UL.
UL certification applies to:
- Electronic and electrical products: such as televisions, microwaves and refrigerators.
- Mechanical products: includes industrial machines, household appliances, and automotive parts.
- Electromechanical products: such as power tools, electric vehicles, and integrated electromechanical devices.
- Medical devices: such as medical electronic devices, imaging equipment, and monitoring devices.
Fire and building safety products: including fire doors, fire extinguishers, and smoke detectors.
ETL certification applies to:
- Power tools: such as drills, electric screwdrivers, and saws.
- Lighting and switches: such as LED ceiling lights, chandeliers, and wall switches.
- Electronic components: such as capacitors, resistors and diodes.
Electronic toys: Includes remote-controlled cars, electric dolls, and electronic construction sets.
ETL certification is suitable for budget-conscious products that require rapid market entry. For fast-cycle products, such as LED lights , with short production times and frequent market updates, ETL certification offers a better value.
Despite higher costs and longer processing times, UL certification is often chosen for consumer products closely linked to everyday life, such as household appliances like microwaves and ovens, due to its high safety requirements and wider market acceptance.
Frequently Asked Questions
What does UL mean in the electrical market?
In the electrical market, UL is a highly respected and prestigious organization that sets safety standards for electrical products in North America. UL certification is crucial in this market, as it signifies that a product has been rigorously tested and meets strict safety requirements.
Are ETL and UL certification the same thing?
ETL and UL certifications are not exactly the same, as they are issued by different organizations. ETL certification is provided by Intertek, while UL is issued by Underwriters Laboratories. Companies often choose either UL or ETL certification because their testing standards are the same. This means they can be used interchangeably in some areas. However, UL is generally considered more reliable.
Is ETL certification as good as UL?
In some categories, ETL certification is just as valid as UL, as they typically use the same testing standards. However, UL is better known and recognized in the North American market. On the other hand, obtaining ETL certification is typically faster and cheaper. Therefore, determining which is better depends on the specific product and your priorities.
