Bulls (intact males) and steers (castrated males) are distinguished at this subheading level because they represent different animal types with distinct market values and processing considerations. The separate classification allows for more precise trade data collection and may reflect different duty or quota treatment depending on trade agreements.

Intact bulls may be subject to additional health screening requirements, particularly regarding reproductive disease status. APHIS import protocols specify testing and certification requirements that may differ from those for steers. Importers should consult current APHIS import requirements for the specific country of origin.

No. Animals entered under the immediate slaughter designation are legally required to proceed to slaughter. Diverting them to breeding or other uses without prior APHIS and CBP authorization would constitute a violation of import conditions and could result in penalties and forced exportation or destruction of the animals.
