UN2900 (Category A, Infectious Substance Affecting Animals Only)
Also: UN2900
The dangerous-goods entry for a Category A infectious substance capable of causing serious disease in animals but not in humans.
Foot-and-mouth disease virus, African swine fever virus and classical swine fever virus are the usual examples, and all three are listed for cultures only. The transport requirements match UN2814: Packing Instruction 620, a Class 6.2 label, a full declaration, a trained shipper, and carrier acceptance on the lane established before collection.
The distinction from UN2814 is not cosmetic. It changes which regulator authorises the movement, because an animal-only pathogen pulls in veterinary and animal health import controls rather than public health import permits.
The host-range question in the infectious substance classifier is where the two entries separate.
