MODALITIES

Certification modalities or schemes established in Mexico through conformity assessment policies and procedures, under which a certificate or opinion may be obtained, are listed below. Select the scheme according to the type of product and your certification needs.

With verification through Regular Product Testing

It basically consists in submitting your Request and current Product Test Result Report (no more than 90 days from the date of issue), along with relevant technical and legal documents.

The certificate is subject to annual verification (follow-up) and is valid for 1 year.

Under this modality, ownership extensions may be given upon certificate holder’s request. Both the holder and the person to whom the extension is given are responsible for the ownership. Ownership extensions are also subject to verification. Extension validity shall be the same as base certificate validity.

With verification through Production Line Quality Management System

Under this modality, you may obtain a certificate valid for 3 years, as long as you have a Quality Management System (QMS) certified under Sector 19 of the International Accreditation Forum (IAF) by an accredited system agency.

In order to certify a product under this modality, a pre-inspection visit is required by UL for the purpose of obtaining the corresponding System Certification Report. If applicable, product sampling that should be taken to the laboratory to obtain the Test Result Report, is also required. This service is performed only if the quote proposed is approved by the customer. This quote includes a pre-inspection visit, a product certification, a routine on-site visit, and a result analysis.
