If you are looking at the new USMCA template, you will see an area for a Certifier.
You determine who the certifier is for this field. You can opt for the importer, exporter, or producer.
The exporter is from the Export Entities screen while the Importer and Producer are identified on the Other Entities Screen and chosen by their role.
We partner with companies we can recommend who specialize in compliance classifications to give you a hand on all of your products for USMCA and full compliance with other regulations.
