Establishes provisions relating to the creation of a vapor product directory

HB 276 requires vapor product manufacturers selling in Missouri to certify annually (starting January 1, 2026) that their products meet federal FDA requirements, such as having FDA marketing authorization or meeting specific pre-2020 application deadlines. Manufacturers must list each product separately on the certification form and notify the Attorney General of any changes within 30 days. The Attorney General must then create and maintain a public online directory by June 1, 2026, listing all certified manufacturers and products. This directly affects vapor product manufacturers operating in Missouri and ensures only compliant products are listed for public access. The law establishes a verification process but does not alter existing FDA regulations.
