1604.11.40.40 - Other

This HTS classification covers canned salmon that does not fall under specific species classifications. While Chapter 16 broadly deals with preparations of fish, this particular subheading, 1604.11.40.40, is for whole or piece salmon which has been preserved by canning, but is not specifically identified as Chum (dog), Pink (humpie), or Sockeye salmon. The "Other" designation indicates it encompasses any canned salmon not otherwise enumerated at the preceding level.

The distinction between this category and its siblings, 1604.11.40.10 (Chum), 1604.11.40.20 (Pink), and 1604.11.40.30 (Sockeye), lies solely in the species identification of the salmon. If the canned salmon can be identified by its species and matches one of the preceding codes, it should be classified accordingly. This category serves as a residual for canned salmon where species-specific identification is not made or possible.

As this is a leaf node, there are no further subcategories under this specific HTS code. Classification under 1604.11.40.40 is final for canned salmon that is not specifically identified by species and aligns with the broader scope of prepared or preserved fish, whole or in pieces.
