0302.89.50.37 - Smelts

HTS code 0302.89.50.37 specifically classifies "Smelts" when they are fresh or chilled and are not fillets or other fish meat of heading 0304. Smelts are small, silvery, elongated fish belonging to the family Osmeridae, commonly found in both saltwater and freshwater environments. This classification applies to the whole, unprocessed fish, as opposed to processed forms.

This particular subheading is nested within a broader category for "Other fish, excluding edible fish offal," and then further refined as "Other" within that. It is important to distinguish smelts from their sibling categories, which include other specific types of fish such as cusk, shad, sturgeon, sable fish, and ocean perch. While all are fresh or chilled fish, the unique species characteristics and common trade names dictate their separate classifications. The absence of subcategories indicates that "Smelts" is a terminal classification for this specific product within the HTS.
