Recent MERCOSUR activity impacting food-contact materials includes the publication of Resolution GMC Res. No. 34/25 (MERCOSUR Technical Regulation on Silicones for the Manufacture of Materials, Packaging, Coatings and Equipment Intended to come into Contact with Food) on December 18, 2025 and the initiation of a review and revision of GMC Res. No. 02/12 (Technical Regulation on the positive list of monomers, other starting substances, and polymers authorized for the manufacture of plastic packaging and equipment in contact with food).

The review and revision of GMC Res. No. 02/12 was initiated at the October 2025 MERCOSUR Food Commission Meeting based on a request submitted by the Argentine delegation. Proposed revisions included:

• Updating the positive list in accordance with the EU Plastics Regulation (EU) No 10/2011 and its amendments;
• Revoking the authorization for the use of BPA in plastic materials and polymeric coatings; and
• Authorizing the use of starting substances obtained from any source, including waste.

The revisions to GMC Res. 02/12 are scheduled to be discussed during the next MERCOSUR Food Commission Meeting.
