Live Female Buffalo, 200–320 kg (Non-Purebred, Non-Bison)

CBP officers or APHIS inspectors may weigh animals at the port of entry or rely on weight documentation provided by the exporting country's veterinary authority. If an animal's weight falls outside the 200–320 kg range at the time of importation, it must be classified under the appropriate weight-based alternative line.

American bison (Bison bison) and water buffalo (Bubalus bubalis) are distinct species that occupy separate HTS subheadings. The exclusion prevents misclassification of bison — which have their own tariff lines — as water buffalo. Importers should ensure veterinary health certificates clearly identify the species to avoid reclassification at the border. Consult a licensed customs broker if species documentation is unclear.
