0307.31.00.10 - Farmed

This HTS classification covers mussels (species of the genera *Mytilus* and *Perna*) that are presented live, fresh, or chilled. This includes mussels kept alive for sale, those recently harvested and kept in their natural state, or those that have been cooled to maintain freshness after harvest but have not been frozen, dried, salted, or otherwise preserved. The "farmed" designation within this code specifies that the mussels were cultivated through aquaculture rather than harvested from wild populations.

This category is distinguished from its sibling, 0307.31.00.90 "Other," which would encompass mussels presented in any other state of preservation, such as frozen, dried, salted, in brine, or smoked. The core distinction lies in the method of preservation and presentation; this specific subheading is exclusively for mussels in their most immediate post-harvest state.

As a leaf node, there are no further subcategories within 0307.31.00.10. Classification at this level is determined by the identity of the mollusc (mussels), the condition in which it is presented (live, fresh, or chilled), and the origin of the product (farmed). Importers and exporters should ensure accurate documentation regarding the state of the product and its cultivation method to ensure correct classification.
