Legal notes
Additional notes
1. For the purposes of subheadings 03053211 and 03053219, cod fillets (Gadus morhua, Gadus ogac, Gadus macrocephalus) having a total salt content by weight of 12 % or more which are fit for human consumption without further industrial processing, are considered to be salted fish.
However, frozen cod fillets which have a total salt content by weight of less than 12 % are to be classified under subheadings 03047110 and 03047190, in so far as the actual and lasting preservation depends essentially upon freezing.
2. For the purposes of the subheadings referred to in the third paragraph, the term ‘fillets’ includes ‘loins’, i.e. the strips of meat constituting the upper or lower, right or left, side of a fish insofar as the head, guts, fins (dorsal, anal, caudal, ventral, pectoral) and bones (spinal column or main backbone, ventral or costal bones, branchial bone or stapes, etc.) have been removed.
The classification of such products as fillets is unaffected by cutting them into pieces, provided that these pieces can be identified as having been obtained from fillets.

(a) tuna, of the genus Thunnus, of subheadings 03044990 and 03048700;
