General Considerations
Identify required technical and legal documentation, according to the application form (or to "Required Documentation" item under the NOM PCO Services section,) that applies to the type of product and method.
Check if you have the latest version of the forms being submitted (downloadable documents found here are their latest version.)
Once application is received and detected flaws are corrected, response time is of seven (7) business days for new products, at most, and twenty (20) business days for reconstructed, reconditioned, used, second-hand, second-line, discontinued, and non-compliant articles.
NOM certificates will only be granted to importers, manufacturers, and sellers from Mexico or from countries with which the Mexican government has signed an Agreement or Free Trade Treaty (that includes surveillance activities.)
Submit two (2) original copies of a Service Agreement (only applicable for first-time procedures,) signed on every page and corresponding sections.
Handling companies (intermediaries or agencies) need copies of Service Agreements signed, with initials on every page, by the legal representative of the manufacturer/importer (certificate owner,) as well as the respective power of attorney documentation signed by the legal representative or certificate owner's authorized representative. Power of attorney documentation must include intermediary/agent name and address, specifying company and/or individual(s) authorized to sign the documentation required by the corresponding services. All communications regarding the services will be performed by the authorized individual(s) mentioned in the power of attorney documentation.
Submit product dictum or current test reports, considering the following information as "current":
- ninety (90) calendar days from issuing date
- six (6) months from lab test issuing date for Scheme V. Additionally, reports must have the following heading: "Dictamen de laboratorio para certificación NOM simplificada para franja y región fronterizas". ("Laboratory Test Report for Simplified NOM Certification for Border Strips and Regions.")
Test reports will only be validated if issued by a laboratory subcontracted and/or validated by UL de México. You may also find the aforementioned lists at our offices.
If test results are generated by Mutual Recognition Agreement (MRA), the following must be submitted:
- Original test results and validation letter issued by a laboratory subcontracted or validated by UL de México, or
- Validated test results, that is, generated by a subcontracted laboratory based on the original test results, elaborated on their own result validation form.
Please, save a copy of the documentation being submitted and/or generated during the certification process in case UL de México personnel requests them at a later time. UL de México will assign a reference number to each application, which the client can use to follow up on the procedure with our Customer Service Department.
If you chose to pick up the certificate or documentation at your facilities, please remember to bring the respective application receipt or a checklist stamped by UL de México.
Application receipts do not guarantee that corresponding certificates or a dictum will be issued, for they depend on compliance evaluation analysis.
You will receive the corresponding notification if flaws or non-compliances are detected during analysis and evaluation processes. Such flaws or non-compliances must be corrected before certification process is resumed.
If assessment results are satisfactory, UL de México will issue the corresponding product certificate or compliance dictum, which will be subject to surveillance (follow-up), if needed (please refer to Certificate Surveillance (Follow-Up), Suspension, Cancellation Process).
Certificate expiration is dependant on the type of application scheme (for more detail, please refer to the Certification Schemes section).
Additionally, please keep in mind that the information on the application, be it signed by a Legal Representative or Agent/Intermediary (authorized by general power of attorney), is provided under oath and, once the compliance certificate is issued, product must display compliance marks according to UL de México Mark Usage Manual.
