Mercosur Sets BS EN 646 Gray Scale Requirements for Food Contact Cellulosic Materials and Articles

SafeGuardSHardgoodsDecember 12, 2022

SG 138/22

Mercosur has approved an amendment to its technical regulation on food contact paper and board. Member states are required to transpose the revision into their national law by May 16, 2023.

In November 2022, the Southern Common Market (Mercado Común del Sur, Mercosur) issued Mercosur/GMC/Res. No. 26/22 to revise GMC Resolution No. 40/15 ‘Mercosur Technical Regulation on Cellulosic Materials, Packaging and Equipment Intended to be in Contact with Food’.

The latest amendment establishes a gray scale of 5 for the migration of pigments and dyes from food contact cellulosic materials and articles when tested to BS EN 646 ‘Paper and board intended to come into contact with foodstuffs – Determination of color fastness of dyed paper and board’.

Member states (Argentina, Brazil, Paraguay and Uruguay) are required to transpose the amendment into their national law before May 16, 2023.

Highlights of the changes in the amendment and a comparison with GMC Resolution No. 40/15 are summarized in Table 1
