On October 27th, 2017, Mexico's NOM-029-ENE-2017 was published. It deals with the Energy Efficiency of External Power Supplies and will be in force on April 15th.
To be exempt from this law, manufacturers of products with these types of power sources MUST start certification requests NOW.
After this date, Customs officials will be requesting the new certificate of compliance. Additional testing will be mandatory for any new power supplies requesting certification after this date. Contact ORBIS to get your process started, and ensure your product is grandfathered before April 15th.
