Ohio Rev. Code § 3739.09
A manufacturer shall recertify each cigarette the manufacturer certifies pursuant to section 3739.07 of the Revised Code every three years. A manufacturer that certifies a cigarette in accordance with that section and that subsequently makes any change to that cigarette that alters the cigarette in such a way that the manufacturer knows that the cigarette is likely to no longer meet the standard specified in section 3739.03 of the Revised Code or the standard approved under section 3739.04 of the Revised Code shall not sell or offer to sell that cigarette in this state until the manufacturer retests the cigarette in accordance with the testing standards specified in section 3739.03 of the Revised Code or approved under section 3739.04 of the Revised Code. The manufacturer shall maintain records of that retesting in the same manner as the manufacturer maintains records under section 3739.05 of the Revised Code. A manufacturer shall not sell in this state any altered cigarette that does not meet either the performance standard set forth in division (B)(3) of section 3739.03 of the Revised Code or the performance standard approved under section 3739.04 of the Revised Code.
