What applies in Iowa
Without a state law, products sold in Iowa still have to meet federal rules, including EPA's one-time TSCA PFAS reporting rule, and any product sold into other states has to meet those states' bans. Retailers selling nationally often apply the strictest state rule across their range.
Neighboring states with PFAS laws: Minnesota (12 product bans), Wisconsin (firefighting foam only), Illinois (5 product bans).
