(a)(1) Each dealer, manufacturer, refiner, or special fuel seller who imports motor fuel into the State shall submit to the Comptroller refinery specifications, including additive specifications, without regard to where the additives become part of the motor fuel.

(2) The Comptroller may waive this section only when consumers in the State otherwise would be subject to extreme hardship during an emergency or civil disturbance.

(b)(1) When submitting refinery specifications, a dealer, manufacturer, refiner, or special fuel seller, with the approval of the Comptroller, may designate 1 or more components of the motor fuel, including an additive, as a trade secret.

(2) In determining whether a component is a trade secret, the Comptroller shall consider whether a chemist who uses modern analytical techniques reasonably could be expected to identify the component.

(3) The Comptroller shall make every reasonable effort to protect the trade secret.
