9815.00.40.00 - Fish (except cod, cusk, haddock, hake, mackerel, pollock and swordfish), the product of American fisheries, landed in a foreign country and there processed by removal of heads, viscera or fins, or by chilling or freezing, or by any combination of these processes, but not otherwise processed

This HTS category, 9815.00.40.00, specifically addresses certain fish products that originate from American fisheries but have undergone minimal processing abroad. The defining characteristic is that these fish, excluding cod, cusk, haddock, hake, mackerel, pollock, and swordfish, are landed in a foreign country and then subjected to processes such as the removal of heads, viscera, or fins, or chilling or freezing. Crucially, the processing must not go beyond these basic steps; any further significant alteration would place the product in a different classification.

This provision distinguishes itself from other classifications by its focus on the origin of the fish and the specific, limited nature of the foreign processing. Unlike categories for raw, unprocessed fish or those that have undergone extensive culinary preparation, this code captures a unique intermediary state. Its placement within Chapter 98, "Special classification provisions," highlights its unique tariff treatment, often related to encouraging domestic fishing industries or specific trade agreements.

As this is a leaf node within the HTS, there are no further subcategories under 9815.00.40.00. Classification under this code is therefore direct, contingent on meeting all the stipulated criteria regarding the type of fish, its origin, and the extent of foreign processing. Importers must carefully verify that the product aligns precisely with the description to ensure correct duty assessment and compliance.
