Swine imported for exhibition, agricultural fairs, research purposes, or other uses that do not qualify as immediate slaughter or breeding animals would be classified here.

Importers should maintain records of the intended use at the time of entry, such as contracts with research institutions or fair registration documents, to support the classification in the event of a CBP audit.

Not necessarily; each 10-digit code may carry a distinct duty rate under the US tariff schedule, and applicable trade agreement rates should be checked separately for this residual category.
