the full name of tsca is the toxic substance control act, which was officially implemented on october 11, 1976. the act aims to comprehensively consider the environmental, economic and social impacts of chemical substances circulating in the united states. and prevent "unreasonable risks" to human health and the environment. after several revisions, it has now become the effective regulation of chemical substances in the united states.

the hazardous substances final rule is based on tsca section 6 requirements that require epa to take expedited regulatory action to regulate persistent, bioaccumulative and toxic (pbt) chemicals, and the final rule must be issued within 18 months of issuing the proposed rule, banning or restricting the production, processing and distribution of hazardous substances. at present, the u.s. environmental protection agency (epa) has issued a final rule for the control of hazardous substances to control 5 pbt substances, and has released 33 substances for risk assessment, of which 10 substances have completed the final risk assessment.

the tsca act divides chemical substances in the united states into "existing substances" and "new substances" for management. for substances not listed on the tsca list, i.e. new substances, if the exemption conditions are not met, the manufacturer or importer of the substance must make a pmn (pre-manufacturing) declaration. for "existing substances", companies need to focus on two control requirements of the significant new use rule (snur) and the hazardous substances final rule. among them, the hazardous substances final rule is based on the requirements of section 6 of tsca, which requires epa to take rapid regulatory action to control persistent, bioaccumulative and toxic (pbt) chemical substances, prohibit or restrict the production, processing and distribution of hazardous substances, aiming at reducing the exposure of these substances to the human body and the environment.
