0302.89.50.49 - Shad and sturgeon

This classification covers specific types of fish, namely shad and sturgeon, when imported or exported fresh or chilled. These fish are distinct from fillets and other fish meat, which fall under heading 0304. The primary distinction of this category lies in the specific species identified: shad, a migratory fish found in both freshwater and saltwater, and sturgeon, a prized fish known for its roe (caviar) and historically significant meat.

Unlike sibling categories that may cover other specific fish like smelts, cusk, sable fish, or ocean perch, this node is exclusively dedicated to shad and sturgeon. This specificity ensures that these particular species are not misclassified with other "other fish" categories that do not explicitly name them. For instance, while other "other fish" might include a broad range of less commonly specified species, this subheading provides a precise classification for shad and sturgeon.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the classification criteria rely solely on the accurate identification of the imported or exported product as either shad or sturgeon, in a fresh or chilled state. This level of detail is crucial for accurate tariff application and trade statistics for these specific aquatic products.
