What is the e-mark?

The e-mark is a symbol which may be put on packages in the same field of vision as the nominal quantity.  It must be at least 3 mm high. Specifications for the e-mark are given in the regulations. 

The e-mark constitutes a guarantee by the packer or importer that packages have been made up in accordance with the average quantity system.  Authorities in any of the other Member States will contact Legal Metrology if they find non-compliant Irish products on their market.
 

Are there any restrictions on the use of the e-mark?

The e-mark may only be marked on packages having a nominal quantity of not less than 5g or 5ml and not more than 10kg or 10 litres and may only be applied by the packer or importer.
