According to the commission, evidence suggests that exporters are avoiding the duties by making small modifications to the covered products, either by applying a coating of oil, slightly increasing the amount of alloying elements, or by changing the anti-corrosion coating from zinc or aluminum to zinc-magnesium-aluminum.
