Here in the states, there are, in fact, standards, even if they are not followed. Anything can be in a package labelled Chili Powder, as that does not have an official designation. Chile powder, must be made from ground chiles only and cannot have any other spices. It is the difference between Chili (a dish) and chile (peppers of the Capsicum genus). Hence, Gebhardt, McCormicks and many other Chili powders, versus ground up chiles.
