USDA APHIS evaluates the disease status of the exporting country or region for conditions including classical swine fever, African swine fever, foot-and-mouth disease, and swine vesicular disease. An outbreak in the exporting region can trigger immediate import suspension. Importers should monitor APHIS veterinary equivalence determinations and any active import alerts before committing to a shipment.

The US schedule separates swine at 50 kg or more into slaughter-destined animals (0103920010), breeding animals (0103920020), and a residual 'other' category (0103920091). The intended use must be declared at entry and is subject to CBP verification; reclassification after entry can result in additional duties and penalties. Importers should ensure that commercial invoices and APHIS health certificates consistently reflect the same intended use.
