We believe that the 'e' is only applicable to pre-packaged items and fresh face masks would not qualify to have the 'e' on the label as not based on an average fill.
As a bit of background we have been picked up on this by French regulators who have said "a specific balance must be used and controlled regularly" - and for those products 'in-shop packaged' this is not satisfied.
Below are the rules on using this symbol
Rules for using the Estimated Symbol in the European Community include:
1.The average quantity of product in a batch of prepackages shall not be less than the nominal quantity stated on the label.
2.The proportion of prepackages having a negative error greater than the tolerable negative error shall be sufficiently small for batches of prepackages to satisfy the requirements of the official reference test, as specified in legislation.
3.No prepackage having a negative error greater than twice the tolerable negative error may bear the Estimated Symbol.
4.The nominal quantity (nominal weight or nominal volume) expressed in kilograms, grams, litres, centilitres or millilitres, and marked in figures 3 mm high if it is from 200 g or 20 cl down to but not including 50 g or 5 cl, 2 mm high if it is not more than 50 g or 5 cl, followed by the symbol for the unit of measurement used or where appropriate by the name of the unit in accordance with Directive 71/354/EEC, as last amended by Directive 76/770/EEC.
5.Failure to comply with the above requirements, or violations such as incorrect size, location or font, can result in penalties such as the recall of all goods, fines, and even prohibition from conducting business in the EU.
6.Finished products of 5 g or 5 ml or less are not eligible to use this symbol.
