Overview

This HTS classification, 0303.45.01.10, specifically covers frozen Atlantic bluefin tuna (Thunnus thynnus). This category falls under the broader heading of frozen fish, excluding fillets and other fish meat. It further narrows the scope to include tunas of the genus Thunnus and skipjack tuna, but this specific subheading is dedicated exclusively to the Atlantic bluefin tuna species.

The primary distinguishing feature of this category from its sibling, 0303.45.01.50 (Thunnus orientalis), is the species of bluefin tuna. While both are types of bluefin, 0303.45.01.10 is reserved for the Atlantic variety, whereas its sibling pertains to the Pacific bluefin tuna. Both are classified as frozen fish, and the distinction is based on precise species identification, a critical factor in international trade regulations and fisheries management.

As a leaf node, this category does not have further subcategories. Therefore, classification at this level is definitive for frozen Atlantic bluefin tuna. Customs professionals should rely on species identification documentation and, where necessary, scientific verification to accurately classify frozen tuna specimens under this code, ensuring compliance with all applicable trade and conservation measures related to Thunnus thynnus.
