Hawaii has no statewide plastic bag preemption law, but all four counties have enacted bans on non-recyclable plastic checkout bags, making Hawaii the first U.S. state with a de facto statewide ban on single-use plastic bags.
Hawaii's legislature has not preempted county regulation of single-use plastics, allowing each county to adopt independent ordinances. Honolulu (ROH Chapter 9, Article 9), Maui County (Title 20.26), Hawaii County (HCC Chapter 14, Article 14), and Kauai County (KCC Chapter 8) all prohibit retailers from providing non-recyclable plastic checkout bags at point of sale. Most ordinances also restrict thin compostable bags and require minimum recycled content for paper bags. Fees on reusable or paper bags vary by county. The combined effect is that retailers across Hawaii must offer reusable, paper, or compliant compostable bags only. Statewide grocery and retail chains generally comply with the most restrictive county rule across all locations.
County ordinance violations typically carry $100 to $1,000 fines per offense, escalating with repeat offenses.
