Marks for Latin America


UL AR Mark

Used in conjunction with the mandatory S Mark of Argentina’s National Office of Internal Commerce (Direccion Nacional de Comercio Interior, or DNCI), the UL-AR Mark indicates a product’s compliance with Phase III of Argentina’s Resolution 92/98. Most electrical and electronic products entering Argentina will have to display the S Mark adjacent to the mark of an accredited and recognized third-party certification organization such as UL de Argentina, S.R.L


UL BR Mark

Used in conjunction with the INMETRO Mark of the National Institute of Metrology, Standardization and Industrial Quality in Brazil, the UL-BR Mark indicates that a product complies with the Brazilian standards that are primarily modeled after IEC/ISO standards with some local deviations. Certification is mandatory for specific products including switches, plugs, socket outlets, flexible cords, circuit breakers, wire and cable, magnetic and electronic ballasts, voltage regulators, medical devices, and electrical equipment for hazardous locations. UL do Brasil is accredited to provide this certification. Voluntary certification can be obtained for other products including audio, video and information technology equipment to differentiate product in the competitive Brazilian market.

Scope of Accreditation


nom mexico

The UL-MX Mark is a safety Mark registered and provided by UL de Mexico, S.A de C.V. It is used for products that have been evaluated and certified under voluntary Mexican standards (NMX). Used in conjunction with the official NOM countersign, it is considered an official mark of Mexico. UL-MX NOM Marks are only granted when a product complies with applicable and mandatory requirements of the official Mexican standards (Normas Oficiales Mexicanas or NOM), the scheme/modality under which it has been evaluated, and current Mexican legislation related to conformity assessment. In any case, the validity of the associated certificate of compliance will depend on the certification scheme applicable at the product’s category, e.g., new, used, rebuilt, out of specifications, etc.

UL Follow-Up Services

We protect your investment in our certifications by maintaining an ongoing business relationship with manufacturers using the UL Mark.

Throughout the lifetime of a UL certification, we regularly audit a manufacturer’s production facilities and products to determine continued compliance with our requirements. The frequency of inspection is based on the type of product or number of UL Marks applied. Our field engineers conduct factory audits and sampling of certified products to assess continued compliance with our requirements. By protecting the integrity of our certifications, we help add value to your brand.

We share a common goal with you in helping ensure only those products fully complying with our requirements carry the UL Mark.

We also offer you customized on-site support and training to help you prepare for your first UL Follow-Up Services visit.

Field Evaluations

Site-specific field evaluations help regulatory authorities determine the compliance of a product, leading to approval of the installation. UL’s evaluation process consists of documentation review, visual and mechanical inspection, suitability for installation in accordance with the adopted installation code(s) such as the National Electrical Code® (NEC®), applicable testing and an engineering report. UL’s Field Evaluation services can be requested by anyone involved with the product including business owners, manufacturers and contractors.

COVID-19 Response

We are here to help during this challenging time and are continuing to conduct field evaluations. The health and safety of our field engineers is our top priority and certain conditions must be met prior to scheduling an evaluation. Please contact us for more information.
