0204.30.00.00 - Carcasses and half-carcasses of lamb, frozen

This HTS category, 0204.30.00.00, specifically covers carcasses and half-carcasses of lamb that have been preserved by freezing. This means the entire body of the lamb, or its two halves following a lengthwise cut down the backbone, are included, provided they are in a frozen state at the time of import or export. This classification is situated within Chapter 2 of the Harmonized Tariff Schedule, which broadly deals with meat and edible meat offal.

It is crucial to distinguish this category from its siblings based on the preservation method and the specific part of the animal. For instance, 0204.10.00.00 covers carcasses and half-carcasses of lamb that are fresh or chilled, not frozen. Other sibling categories within 0204 address "other meat of sheep" (which would exclude carcasses and half-carcasses and include cuts) and "meat of goats." Therefore, the defining characteristic for 0204.30.00.00 is both the form (carcass or half-carcass) and the frozen state of lamb meat.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is specific to the described product. When classifying goods under this heading, customs officials will look for evidence that the product is indeed lamb, presented as a whole carcass or in two halves, and that it has undergone a freezing process for preservation.
