Amazon Sellers: A Third-Party Test Report Does Not Entitle You to Use the UL Mark

How to verify whether your product is actually UL certified

UL Solutions has continued to pursue enforcement in the United States against unauthorized use of the UL mark, and Amazon sellers are within scope.

In 2023, UL sued two vape device companies in the Northern District of Illinois; the case resolved through a consent judgment and roughly $2.2 million in payments. The companies involved were ordinary sellers, not counterfeiters in the conventional sense.

Many of the sellers sued had not appreciated the risk beforehand, generally assuming that once a product had been tested to the relevant UL standard, compliance was complete.

That is usually where the problem lies.

I. A Test Report and UL Certification Are Two Different Things

In practice, at least two distinct questions must be separated.

First, whether the product has been tested and conforms to a safety standard. The technical standards UL publishes (UL 2849, for example) are public standards, and third-party laboratories (SGS, Intertek, Bureau Veritas, and others) can test to them and issue reports. Such a report generally establishes only that the sample tested conformed to the applicable technical standard at the time of testing.

Second, whether the product has been certified by UL and is permitted to bear the corresponding UL Mark. The UL Mark is part of UL's certification system; it may be used on products, packaging, or marketing materials only where UL certification has been completed and its usage rules are satisfied.

These two layers frequently appear together in practice, but their legal significance differs. A third-party test report is not equivalent to UL certification, and does not by itself confer any right to use the UL Mark.

II. Amazon's Compliance Requirements Are Not a UL License

In certain categories, Amazon does require sellers to submit test materials showing conformity with applicable safety standards. For many electrical, charging, or battery-containing products, the applicable standards will include UL standards (UL 2849, UL 62368, and others).

Platforms also typically require that test reports come from laboratories accredited to ISO 17025; SGS, Intertek, and Bureau Veritas generally satisfy that requirement.

But that set of requirements addresses whether a product conforms to safety standards — not whether it holds UL certification.

Put differently, submitting the test materials Amazon requires may show that a product satisfies the platform's safety compliance requirements to a degree. It does not mean the product is UL certified, and it does not entitle the seller to use the UL Mark on the product or listing, or to make comparable certification claims.

In a later dispute, a test report may bear on the seller's state of mind — but whether the seller was authorized to use the UL Mark remains a separate question.

III. How to Verify Whether a Product Is Actually UL Certified

UL maintains a public database, Product iQ, for verifying certification information for products and components.

In practice, at least the following should be checked:

First, whether the corresponding certification can be located in the database at all. If it cannot, that at least means certification cannot be assumed on a factory's say-so.

Second, whether the manufacturer, product category, and specific model in the certification record match the product actually being sold. Different models generally require separate certification; a certification for another model or an earlier version cannot simply be carried over.

Third, whether the certification is currently in force and covers the period during which the product is actually sold. Where there is doubt, verify further rather than relying solely on documents supplied by the factory.

If these elements cannot be confirmed, the fact that a product "passed testing" is no substitute for certification itself.

IV. A "UL Certificate" From a Factory Requires Independent Verification

In practice, purported "UL certificates" obtained from factories commonly present one of the following problems: the certificate was not issued by UL; the certification corresponds to a different model; the certification has lapsed; or the product has been modified and now falls outside the scope of the original certification.

Documents supplied by a factory therefore cannot by themselves establish entitlement to use the UL Mark.

The sounder approach is independent verification through Product iQ, confirming certification status further where necessary, rather than relying on a PDF or a screenshot.

V. How the Claim Is Presented Can Itself Create Risk

Many sellers believe that avoiding UL's circular logo avoids UL-related risk.

In practice that understanding is too simple.

In its market surveillance and trademark usage rules, UL is concerned not only with the mark itself but with how the relationship to UL certification is presented overall — on packaging, on listing pages, and in marketing materials. Any presentation that could give consumers an inaccurate or misleading impression of the relationship between the product and UL certification may create risk.

Common high-risk practices include:

• Displaying a standard number such as "UL 2849" in bold, enlarged, or visually central form on a page or package while placing the actual testing laboratory (SGS, Intertek, and so on) in a secondary or de-emphasized position.
• Using phrases such as "meets UL standards," "UL tested," or "UL compliant" without UL certification, where the surrounding context or layout would lead an ordinary consumer to understand that the product is UL certified.

The issue is not any single word but whether the overall presentation constitutes a misleading implication as to certification status.

The test is generally this: reading the page or packaging, would an ordinary consumer be led to believe the product is UL certified?

VI. What Sellers Already Selling Can Do

First, review products on sale one by one, confirming separately whether platform testing requirements are met and whether UL certification has in fact been obtained with the corresponding usage rights.

Second, where certification cannot be confirmed or its status is in question, stop using the UL Mark or comparable statements on the product, packaging, or listing.

Third, require the factory to supply verifiable certification information and verify it independently. Where verification is not possible, assess the options.

Fourth, if a platform notice or claim has already been received, address it promptly. The central question in such matters is usually not whether testing was performed, but whether there has been unauthorized use of a certification mark or a misleading presentation.
