15 U.S.C. § 1203: Preemption of Federal standards

Except as provided in subsections (b) and (c), whenever a flammability standard or other regulation for a fabric, related material, or product is in effect under this chapter, no State or political subdivision of a State may establish or continue in effect a flammability standard or other regulation for such fabric, related material, or product if the standard or other regulation is designed to protect against the same risk of occurrence of fire with respect to which the standard or other regulation under this chapter is in effect unless the State or political subdivision standard or other regulation is identical to the Federal standard or other regulation. The Federal Government and the government of any State or political subdivision of a State may establish and continue in effect a flammability standard or other regulation applicable to a fabric, related material, or product for its own use which standard or other regulation is designed to protect against a risk of occurrence of fire with respect to which a flammability standard or other regulation is in effect under this chapter and which is not identical to such standard or other regulation if the Federal, State, or political subdivision standard or other regulation provides a higher degree of protection from such risk of occurrence of fire than the standard or other regulation in effect under this chapter. compliance with the State or political subdivision requirement would not cause the fabric, related material, or product to be in violation of the standard or other regulation in effect under this chapter, and the State or political subdivision standard or other regulation (i) provides a significantly higher degree of protection from the risk of occurrence of fire with respect to which the Federal standard or other regulation is in effect, and (ii) does not unduly burden interstate commerce. A regulation under paragraph (1) granting an exemption for a flammability standard or other regulation of a State or political subdivision of a State may be promulgated by the Commission only after it has provided, in accordance with section 553(b) of title 5 , notice with respect to the promulgation of the regulation and has provided opportunity for the oral presentation of views respecting its promulgation. In this section, a reference to a flammability standard or other regulation for a fabric, related material, or product in effect under this chapter includes a standard of flammability continued in effect by section 11 of the Act of December 14, 1967 ( Public Law 90–189 ).
