This subheading covers bone-in rib cuts such as standing rib roasts, ribeye with bone, and short ribs that meet US Note 3 criteria and have not been processed. The specific cut must retain the bone and originate from the rib section of the bovine carcass.

US Note 3 qualification typically provides access to a preferential or quota-based duty rate compared to non-qualifying bone-in beef. Importers should verify the current in-quota and over-quota rates in the HTSUS and confirm their product meets the note's criteria before entry.

Dry or wet aging alone does not necessarily constitute 'processing' under the HTSUS chapter notes, but importers should confirm with CBP or seek a binding ruling, as the definition of 'processed' is specific and any additional preparation steps could affect classification.
