1604.11.20.90 - Other

This HTS classification, 1604.11.20.90, encompasses "Other" prepared or preserved fish, specifically salmon in oil, packaged in airtight containers. This category is for salmon products that do not fall under more specific descriptions within the salmon group. The defining characteristic is the preparation method: whole or piece salmon preserved in oil and sealed within airtight containers to ensure shelf stability and quality.

Distinguishing this category from its siblings, 1604.11.20.20 (Pink salmon) and 1604.11.20.30 (Sockeye salmon), is crucial. While all fall under salmon preserved in oil in airtight containers, this residual "Other" category is for any salmon species not specifically enumerated. For instance, if a shipment contains preserved Atlantic salmon or Coho salmon in oil in airtight containers, and these are not explicitly listed elsewhere in the subheadings, they would be classified here. The focus remains on the form (whole or pieces), the preservation medium (oil), the container type (airtight), and importantly, the salmon species' identity.

As this is a terminal classification (a leaf node), there are no further subcategories. Classification at this level requires careful verification that the product is indeed salmon, preserved in oil within an airtight container, and does not conform to any of the more precisely defined sibling categories by species. The intent is to capture all remaining eligible salmon preparations that meet the general criteria but lack a specific species designation at this detailed level.
