China CFSA Consults on 4 New Additives and 6 Resins for Food Contact Materials

The majority of additives and resins included in these amendments are applied in food-contact paints and coating.

On Mar. 21, 2019, China CFSA opened public feedback on 10 new food related products, including 3 additives, 6 new resins and 1 additive with enlarged scope. The deadline for comments is Apr. 21, 2019.
