Hawaii has no statewide polystyrene ban, but Honolulu, Hawaii County, Maui County, and Kauai County have adopted ordinances prohibiting food vendors from using polystyrene foam containers for prepared foods.
Like plastic bags, polystyrene foodware is regulated entirely at the county level in Hawaii. Honolulu's ROH Chapter 41-23 prohibits food vendors from selling or providing prepared food in polystyrene foam containers. Maui County (Title 20.25) and Hawaii County (HCC Chapter 14) have similar rules, and Kauai County restricts polystyrene foodware at facilities and county events. Bills to enact a statewide polystyrene ban have been introduced repeatedly in the legislature but have not become law as of 2026. The combined county ordinances effectively cover the entire state's food-vendor industry. Limited exemptions exist for raw meat packaging and pre-packaged products from outside the state.
County polystyrene ordinance violations typically carry warnings followed by escalating fines from $100 to $1,000.
