Title 21 › Chapter CHAPTER 9— - FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter SUBCHAPTER IV— - FOOD › § 343–1

Last updated Apr 6, 2026|Official source

Summary

States and local governments may not make or keep rules for foods sold across state lines if those rules are different from federal food rules. This covers: standards of identity under section 341 and the related rule at 343(g) (with a specific maple syrup exception); several labeling rules listed in 343(c), 343(e), 343(i)(2), 343(w), and 343(x) (again, a maple syrup exception for 343(c)); other labeling rules in 343(b), 343(d), 343(f), 343(h), 343(i)(1), and 343(k) (maple syrup can be excepted for 343(h)(1)); nutrition labeling under 343(q) (except small restaurants or similar places that are not part of a 20-or-more location chain unless they follow the voluntary option in 343(q)(5)(H)(ix)); and claims covered by 343(r) (except claims already exempt under 343(r)(5)(B)). A State or local government can ask the Secretary to allow a different rule. The Secretary may approve it if the rule would not make food violate federal law, would not unduly burden interstate commerce, and is meant to meet a local information need that the listed federal sections do not address.
