Hallo Charles, thank you for your answer.
The Regulation which I quoted is the English version... and the meaning does not seem different from the Italian version.
The problem is that I have already asked the opinion of two different legal authority and ... they gave me two different interpretations!
I was curious to know how the regulation was being applied in other countries.
Not sure if you are talking specifically about Italy or EC members in general ?
I am totally no expert on European Food law but, afaik, there is a hierarchy of EC legislation regarding food safety, weight, volumes etc. Labelling is just one topic within the overall framework.
IIRC, some top categories (one?) are obliged to be implemented by all Members verbatim (presumably assuming an absolute interpretation exists).
Others are acknowledged to be capable of local individual modification as desired by Members although how much variation is "permitted" I have no idea.
The details of this "Power" tree is from memory available on the Europa website or somewhere similar.
In many cases, "interpretation" is often the Name of the Game. A famous example is the requirements of all EC members to implement the EC food safety legislation as involving HACCP. This was ingeniously re-interpreted as a necessity to implement HACCP "Principles" thereby avoiding tricky haccp topics such as Risk Assessment/Identification of CCPs while still using the results of such studies to generate appropriate monitoring forms for routine use by relatively non-technical personnel.
Again, afaik, a Country's Sovereign Right is, i believe, considered to overlay (supercede?) agreements such as above although as recently illustrated, actions based on such may involve "consequences".
I think many manufacturers rely on their desgnated importing agents to resolve export labelling issues. Theoretically one's own Country should be easier but perhaps, as per yr comment, not always.
