The US tariff schedule carves out cod into its own dedicated 10-digit line (0304951010 for minced, 0304951020 for non-minced) because of cod's commercial volume and the need for precise trade tracking. Line 0304951015 is therefore a residual for all other species in the enumerated families — such as hake, pollock (Atlantic), and grenadier — when presented in minced, bulk-pack form over 6.8 kg.

Minced fish meat is produced by mechanical separation or grinding, resulting in a homogeneous paste or granular texture without intact muscle fiber structure. A processing specification or production method certificate from the foreign establishment, combined with organoleptic inspection at the port, is the standard documentation approach. CBP or FDA may request such records during examination.
