What applies in District of Columbia
Without a state law, products sold in District of Columbia 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. The product checker compares District of Columbia with the states around it.
