0309.90.50 - Frozen

This HTS classification, 0309.90.50, specifically covers frozen flours, meals, and pellets derived from molluscs and other aquatic invertebrates that are fit for human consumption. This designation differentiates these products from their fresh or chilled counterparts, which fall under HTS code 0309.90.40. The "frozen" characteristic is the primary distinguishing factor at this level of detail, indicating a specific processing and preservation method.

Further refinement within this category is achieved through subheadings. The subcategory 0309.90.50.30 pertains specifically to frozen conch, while the broader subheading 0309.90.50.90 encompasses all other frozen flours, meals, and pellets of molluscs and other aquatic invertebrates not otherwise specified. This granular division allows for precise identification based on the specific type of mollusc or invertebrate used in the product.
