Cashmere is the fine undercoat fiber of the cashmere goat, while mohair comes from the Angora goat. US tariff schedules treat them as distinct commodities with separate HTS headings, so accurate species identification and supplier documentation are essential to avoid misclassification.

USDA APHIS requires import permits and official health certificates for live sheep and goats. Animals may also be subject to quarantine depending on the country of origin and disease-status designations. Importers should confirm current APHIS requirements well in advance of shipment, as conditions can change with disease outbreaks.
