- ‘Article 1a For the purposes of this Decision “snails” means chilled, frozen, shelled, cooked, prepared or preserved terrestrial gastropods of the species Helix pomatia Linné, Helix aspersa Muller, Helix lucorum and of the species of the family Achatinidae.’
- Helix tubes, or derivatives thereof, with any of the following characteristics:
- Three subsidiaries of ACH-CN active in ship repair (SIREN, TMTM and MECA HELIX, hereinafter ‘the three subsidiaries’) survived but, before long, they experienced economic problems related to the loss of subcontracting from ACH-CN and of shipowners’ confidence.
- The end turns of the filament are defined as being the first luminous turn and the last luminous turn that are at substantially the correct helix angle. For coiled-coil filaments, the turns are defined by the envelope of the primary coil.
