What is a 'Free Carrier - FCA'. A free carrier (FCA) is a trade term designating the location the seller is to deliver goods.

The cost for transportation is included in the price set by the seller, and the risk of loss is initially on the seller, transferring to the buyer upon delivery to the carrier.
The second is also the base unit of time in other systems of measurement: the centimetre-gram-second, metre-kilogram-second, metre-tonne-second, and foot-pound-second systems of units.n 1956, the second was redefined in terms of a year (the period of the Earth 's revolution around the Sun) for a particular epoch because, by then, it had become recognized that the Earth's rotation on its own axis was not sufficiently uniform as a standard of time.
In classical thermodynamics, the second law is a basic postulate applicable to any system involving heat energy transfer; in statistical thermodynamics, the second law is a consequence of the assumed randomness of molecular chaos.
