0309.90.40.90 - Other

This HTS category, 0309.90.40.90, encompasses a broad range of flours, meals, and pellets derived from aquatic invertebrates, specifically molluscs, that are intended for human consumption. This "Other" designation within the subcategory of molluscan products signifies items not specifically enumerated elsewhere at this level of detail. It serves as a residual category for molluscan preparations in these processed forms.

Crucially, this category is distinguished from its sibling, 0309.90.40.30, which specifically covers "Conch" flours, meals, and pellets. Therefore, any processed molluscan product for human consumption falling under this HTS code must not be derived from conch. The classification hinges on the specific type of mollusc used as the source material.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 0309.90.40.90 is final for suitable flours, meals, and pellets of molluscs, other than conch, intended for human consumption. Examples might include processed products from clams, oysters, mussels, or squid, where the primary material is molluscan and the form is flour, meal, or pellet.
