(a) Manufacturers of self-pressurized consumer products containing a chlorofluorocarbon propellant shall provide performance and technical data concerning such products that they import or initially introduce into interstate commerce after February 19, 1978, to prospective purchasers at the time of original purchase and to the first purchaser for purposes other than resale. The data shall consist of the following identification and warning statement: “WARNING—Contains a chlorofluorocarbon that may harm the public health and environment by reducing ozone in the upper atmosphere.”

This identification and warning statement shall appear on the immediate container of the product and also on any outside container or wrapper in which the product is normally offered for sale at retail. The identification and warning statement may appear on a firmly affixed tag, tape, card, or sticker or similar overlabeling attached to the package.
