0103 - Live swine:

Heading 0103 encompasses all live swine, including pigs, hogs, and boars, regardless of age or sex. This classification is specifically for animals of the species *Sus domesticus* and related wild swine. When classifying, consider the defining characteristics of swine, such as their snout, bristly hair, and general porcine anatomy.

Distinguishing 0103 from its siblings is crucial for accurate tariff application. While Chapter 01 broadly covers live animals, 0101 is for equines, 0102 for bovine animals, and 0104 for sheep and goats. Heading 0105 pertains to live poultry, and 0106 covers all other live animals not specified in earlier headings. Therefore, any live animal identified definitively as swine falls under 0103.

Within heading 0103, subheadings differentiate between purebred breeding animals and all other live swine. This distinction is vital for potential preferential tariff treatment or specific import/export regulations associated with breeding stock. The further subdivision, 0103.10.00.00, specifically applies to purebred animals recognized for their superior genetic qualities for breeding purposes, while the "Other" category captures all remaining live swine not meeting these specialized criteria.
