Glazing consists of applying a protective coating of ice to certain frozen seafood products. This ice layer prevents the products from surface drying or dehydration ("freezer burn"). For glazed products, the question arises whether the net weight should or not include the weight of ice.
The answer is provided by Regulation (EU) No 1169/2011 on the provision of food information to consumers, which is applicable from 13 December 2014. In Annex IX (point 5) to that Regulation, it is clearly stated that the declared net weight of glazed food shall be exclusive of the glaze.
According to Implementing Regulation (EU) 2020/2235 Box I.28 of the health certificate must be completed with the net and gross weights. The declared net weight of glazed food shall be exclusive of the glaze.
Consequently, for consistency with Regulation (EU) No 1169/2011 and the information on food labels, the net weight indicated in health certificates and CHEDs for glazed food must follow the same rule and be exclusive of the glaze
