Reminder: Do you have an IMMEX level “A” certification? It’s time to renew.

Back in October 2013, the Mexican government published a few revisions to the IMMEX decree, including requiring participating companies to obtain a certification in order to qualify for certain tax and customs benefits. If your company received a Level “A” certification during 2014, it’s only valid from January 1, 2015, through December 31, 2015. You’ll need to renew the certification by filing a Notice of Renewal, 60 days prior to the certification’s expiration.

The Mexican authorities recently clarified that the 60-day window refers to 60 business days. This means your deadline to submit the Notice of Renewal on the government’s website (“VUCEM” for its acronym in Spanish) is September 25, 2015. The Notice of Renewal online portal is expected to be online soon. Companies failing to meet the renewal deadline will be required to submit a new IMMEX certification request, which will likely delay the process and lead to other unintended consequences.

Have an “AA” or “AAA” certification? Don’t worry—those don’t expire until December 31, 2016, and December 31, 2017, respectively. Therefore, no action is required at this time.
