Cooperation on Rules of Origin: Parties must investigate circumvention, share information, and consult to resolve origin disputes. Contracting Parties must assist in specifying origin on Certificates of Origin, investigate and, where appropriate under domestic law, take legal or administrative action against false origin declarations and document falsification, cooperate fully in alleged circumvention cases (including facilitating joint plant visits and contacts), and promptly consult when circumvention of the rules of origin is suspected to seek a mutually satisfactory solution.
