0306.11.00 - Rock lobster and other sea crawfish (Palinurus spp., Panulirus spp., Jasus spp.)

This HTS classification, 0306.11.00, specifically covers frozen rock lobster and other sea crawfish. These are distinct from other crustaceans in this chapter by their specific biological identification, encompassing species under the genera *Palinurus*, *Panulirus*, and *Jasus*. The "frozen" designation indicates that the primary state of the product for customs purposes is being preserved through freezing.

It is crucial to differentiate this category from its siblings. For instance, 0306.12.00 pertains exclusively to lobsters of the genus *Homarus*. Similarly, 0306.14 covers various types of crabs, and 0306.15.00.00 is reserved for Norway lobsters (*Nephrops norvegicus*). Furthermore, 0306.16.00 and 0306.17.00 are dedicated to different categories of shrimps and prawns, highlighting the detailed specificity within the broader scope of frozen crustaceans.

The subcategories within 0306.11.00 provide further granularity for classification. The subdivision into 0306.11.00.10 for Caribbean spiny lobster (*Panulirus argus*) and 0306.11.00.20 for "Other" allows for more precise identification based on specific species or regional variations within the rock lobster and sea crawfish family. This differentiation aids in accurately applying specific duty rates or trade regulations.
