Do I need to have the UL Mark on my product in the United States?
Is there a law stating that my product should have a UL Mark? Does our product require UL testing?
Manufacturers submit products to UL for testing and safety certification on a voluntary basis. There are no laws specifying that a UL Mark must be used. However, in the United States there are many municipalities that have laws, codes or regulations which require a product to be tested by a nationally recognized testing laboratory before it can be sold in their area. UL is the largest and oldest nationally recognized testing laboratory in the United States. UL does not, however, maintain a list of the jurisdictions having such regulations.
If you plan to market your product nationally or internationally, it is advisable to obtain UL Listing. If a limited marketing program is anticipated, check with the municipal office having jurisdiction in the particular areas to learn the local retail ordinances or product installation requirements applicable in that area.
Many companies make it their policy to obtain UL Listing not only to minimize the possibility of local non-acceptance, but also as a matter of corporate policy and commitment to minimize the possibility of risk in the use of their products.
