0106.12.01.00 - Whales, dolphins and porpoises (mammals of the order Cetacea); manatees and dugongs (mammals of the order Sirenia); seals, sea lions and walruses (mammals of the suborder Pinnipedia)

This HTS category, 0106.12.01.00, specifically classifies live marine mammals belonging to the order Cetacea (whales, dolphins, and porpoises), the order Sirenia (manatees and dugongs), and the suborder Pinnipedia (seals, sea lions, and walruses). These animals are distinguished by their aquatic adaptations and their classification as mammals. The "Other live animals" heading within Chapter 1 provides a broad grouping for live animals not covered by more specific headings, and this subheading further refines this by focusing on aquatic mammalian species.

This classification can be differentiated from its sibling categories by the specific biological orders and suborders it encompasses. For instance, 0106.11.00.00 covers primates, while 0106.13.00.00 deals with camels and other camelids, and 0106.14.00.00 pertains to rabbits and hares. The key distinguishing factor for 0106.12.01.00 is its exclusive focus on the marine mammals listed, which are physiologically adapted for aquatic life and belong to distinct taxonomic groups from land-dwelling mammals.

As a leaf node, this HTS code does not have further subdivisions. Therefore, the classification of live specimens will rely on accurately identifying them as belonging to the orders Cetacea, Sirenia, or the suborder Pinnipedia. The intent for import or export, such as for scientific research, conservation efforts, or accredited zoological display, would also be relevant considerations in conjunction with the species identification.
