You may use the UL-MX NOM Mark on the product package to promote your product’s certification. For certification purposes, the UL-MX NOM Mark must appear on the product unless an alternate location on packaging is specified in writing by UL via a “Notice of Authorization to Use the Mark” or other written communications.
