What year were CFC nolonger manufactured or imported into the us?

Chlorofluorocarbons (CFCs) were no longer manufactured or imported in the United States after 1996, following the provisions of the Montreal Protocol, which aimed to phase out substances that deplete the ozone layer. The phase-out process began earlier, with significant restrictions starting in the early 1990s. By 2010, the production and consumption of CFCs were effectively eliminated in many countries, including the U.S.
