 The "country of origin principle" is a rule that is sometimes advanced with the intention of facilitating the free movement of goods or service providers so as to encourage cross-border competition or, possibly, to encourage individuals or companies to test other markets without having to establish in the target market.It is also sometimes intended to free providers of goods and service from the obligation to accommodate multiple regulatory regimes when trading across borders from a single location.Home state regulation is often held to help the single market, as firms only need to be aware of their own country's laws, rather than 27 sets of national law.
