A bill that sought to include motor-vehicle tires that contain zinc oxide for evaluation as potential priority products under the Green Chemistry program was gutted and replaced with unrelated legislation. When a product is listed as a priority product, it immediately begins a process of hazard evaluations that could lead to regulatory restrictions ranging from a hazard warning label to a full ban on tires containing zinc oxide, which is used in tire manufacturing as a catalyst in the curing process to increase durability. Banning zinc oxide in tires would require extensive changes in tire composition that could affect tire safety.
