Today, the ETL Mark is featured on millions of products sold by major retailers and distributors every day.

The ETL Mark is proof of product compliance to North American safety standards. It is issued by Intertek, a leading third-party testing and certification organization that operates in over 100 countries around the world. Authorities Having Jurisdiction(AHJs) and code officials across the US and Canada accept the ETL Listed Mark as proof of product compliance to published industry standards. Retail buyers accept it on products they’re sourcing. And every day, more and more consumers recognize it on products they purchase as a symbol of safety.

What is the ETL Listed Mark?

The ETL Listed Mark is a certification symbol that is used to indicate that a product has been tested and found to meet the safety requirements of US and Canadian standards. These includes:

  • UL/ULC standards
  • ASTM standards
  • ASME standards
  • ANSI standards
  • CSA standards
  • NFPA standards
  • NOM standards
  • NSF standards

It also means that the product has been manufactured in a facility that follows good manufacturing practices and quality control procedures. The facilities of manufacturers of products that were awarded the ETL Listed Mark might also be subjected to regular follow-up assessments to ensure that said product continues to comply with relevant standards.

How long has the ETL Listed Mark been around?

ETL has a long history that began in 1896 when Thomas Alva Edison founded Electrical Testing Labs (ETL). Edison’s vision was to provide assurance to consumers through product performance and safety testing. When manufacturers apply Intertek’s ETL Listed Mark to their products, the letters “ETL” carry with them a long history of innovation, influence, and independence.

What countries accept the ETL Listed Mark?

The ETL Mark is accepted throughout the U.S. and Canada. However, we are an international certification organization authorized to issue these product safety marks and more: NOM Mark, CE Marking, GS Mark, S Mark.

How is the ETL Listed Mark different from other certification marks?

The ETL Listed Mark is similar to other certification marks such as UL, CSA, and CE, but it has some key differences. For example, UL is a US-based certification mark that is recognized primarily in North America, while CE is a European certification mark that is recognized primarily in Europe. The ETL Listed Mark, on the other hand, is recognized in both the US and Canada.

Why is the ETL Listed Mark important?

The ETL Listed Mark is important because it provides assurance to consumers that a product has been tested and found to be safe, providing peace of mind and confidence in your purchasing decisions. This can be especially important for products that have the potential to cause harm, such as electrical appliances, toys, and medical devices. It also helps to protect manufacturers from liability claims in the event of a product-related injury or accident.

Is ETL compliance mandatory?

Although ETL compliance is not mandatory, products bearing the ETL Mark are deemed in compliance with relevant safety standards. As such, they are trusted to be safe.

Marketplaces, distributors, and retailers are more likely to accept products bearing an ETL Mark as it is recognized and accepted in many countries.

Which products are covered by ETL?

The ETL Listed Mark covers a wide range of products, which includes the following:

  • Commercial and consumer appliances
  • Electric products
  • Cabling products
  • Gas appliances
  • Oil-fueled products
  • HVACR equipment
  • Manufactured wood

How can I tell if a product has the ETL Listed Mark?

The ETL Listed Mark is typically displayed on the product itself, as well as on the packaging and in product literature. It is a distinctive symbol that features the letters “ETL” inside a circle, with the word “Listed” and a file number beneath it.

What should I do if I see a product that does not have the ETL Listed Mark?

If you see a product that does not have the ETL Listed Mark, it may not have been tested for safety and compliance with US and Canadian standards. This could mean that the product is unsafe or could pose a risk of injury or harm. It is always best to choose products that have been tested and certified by a reputable organization like Intertek, GTG.

Can products with the ETL Listed Mark still be recalled or deemed unsafe?

While the ETL Listed Mark provides assurance of safety and compliance at the time of testing and certification, it is still possible for products to be recalled or deemed unsafe after they have been released to the market. This is why it is important to stay informed about any recalls or safety alerts that may affect products you own or are considering purchasing.

What other certifications should I look for when purchasing products?

In addition to the ETL Listed Mark, there are several other certifications and standards that you should look for when purchasing products. These include UL, CSA, CE, RoHS, and more. Each of these certifications indicates that a product has been tested and found to meet specific safety or environmental standards.

How do I ensure compliance with ETL?

In order for a manufacturer to ensure that their products comply with applicable safety standards and can be awarded the ETL mark, it must send one or more samples of the product to Intertek. Intertek tests those products, and when the products are found to be compliant, the manufacturer earns the right to apply the ETL Mark on its products.

There are several steps that manufacturers have to follow in order for their products to be legally recognized as being ETL certified.

Request ETL certification quotation

In order to get a quotation, you should send the following information to Intertek or an Intertek accredited testing laboratory like GTG:

  • Applicant information
  • Product specs
  • Product intended use
  • Information about components
  • Manufacturer information and location

You will then get a quote, which include information such as:

  • Applicable standards
  • Name of the lab
  • Timeline
  • Price
  • Testing fee
  • Certification fee


To get your product ETL certified, you have to get your product tested by an Intertek Nationally Recognized Testing Laboratory (NRTL).

The testing must be performed against relevant standards for your product. Once you accept the quotation provided by Intertek, you should send the following to the lab that will perform the tests:

  • Product samples
  • Technical documentation


Once the product is tested, manufacturers receive a copy of the Constructional Data Report (CDR), which contain information on the production line testing. The report is then used during the quartely inspections (see below).

Manufacturers must also fill out a Client Information Sheet. This form may not be necessary if manufacturers have already completed it beforehand when their project was quoted.


At this point, Intertek provides manufacturers with a Certification Agreement. Upon receiving it, they are required to confirm that they agree with the ETL Certification Program’s terms and conditions.


An initial Factory inspection must be performed to ensure that the manufacturing process is suitable to achieve product compliance. If manufacturers have multiple factories where they have their products made, Intertek carries out an Initial Factory Assessment (IFA) at those locations. Inspections at multiple factories can last 4 to 6 days but can take a shorter time if manufacturers only have one factory. Intertek’s inspections may take longer for international locations.


Finally, manufacturers receive a document from Intertek granting them permission to use the ETL Mark on their products. Intertek only issues this document if the working conditions at the manufacturer’s factory are satisfactory.

Follow up inspections

Intertek performs quarterly, unannounced inspections in order to ensure that:

  • The products are still manufactured in accordance to the CDR.
  • The use of the ETL Mark still respects the conditions described in the CDR and the agreement.

If the inspector would find any problem, the manufacturer should take one or more of the following steps:

  • Amend any non-conformity.
  • Remove the ETL Mark from non-conforming products.
  • Contact Intertek for instructions.
