Pornography as a legal term at the federal level, except the generic terms "hardcore pornography" and "child pornography", has not existed since the 1973 "Miller v. California" case. The United States Supreme Court in "Miller v. California" discussed pornography (which it referred to as "sexually explicit material") in terms of obscenity, which it held did not enjoy First Constitutional Amendment protection, and recognized that individual communities had different values and opinions on obscenity. The Court's definition of obscenity has come to be called the Miller test. Since then several States have passed laws in terms of that test. Relying on the 1930 Smoot-Hawley Tariff Act and under the terms "obscene" and "", the U.S. Customs and Border Protection prohibits the importation of any pornographic material ( "Immoral articles; importation prohibited").
