Mercosur Proposes Changes to Food Contact Plastic Technical Regulations

The World Trade Organization (WTO) has
circulated two notifications signaling Mercosur’s intention to revise its
technical regulations for food contact plastic materials and articles.

The two notifications were submitted by
Paraguay and circulated by the WTO in July 2020. They cover two pieces of draft

  • Mercosur/LXXII
    SGT No. 3/P Resolution No. 2/20 (draft Resolution No. 02/20) – attached to WTO
    document number 20-5191
  • Mercosur/LXXII
    SGT No. 3/P Resolution No. 3/20 (draft Resolution No. 03/20), attached to WTO
    document number 20-5192

If/when approved, Resolution No. 2/20 will
revise sections 5 and 7 of the Annex to GMC Resolution No. 56/92 – General
provisions for food contact plastics. It will change the overall migration
limits and their requirements:

  • Food
    contact plastics – no more than 10 mg/dm²

that meet a specific Mercosur Technical Regulation

substances and polymers authorized for the manufacture of food contact
plastics. Among the provisions in the draft are the addition of 19 new
