• The Carmack Amendment is an amendment to the Interstate Commerce Act that provides that an ordinary carrier who receives property for transportation to a point in another state or territory, the District of Columbia, or a neighboring foreign country, is liable for any loss, damage, or damage that he inflicts on his load. It makes the carrier liable, without proof of negligence, for any damage to the cargo. The amendment, first adopted in 1906, applies to road carriers (UPS, FedEx, etc.), airlines and freight forwarders, as well as railroads and other ordinary carriers.
