The main purpose of this legislative proposal is to impose a 30 percent tax on sheep and lamb products imported from Australia and New Zealand. This measure aims to protect domestic sheep and lamb producers in the United States by making imported products more expensive, thereby encouraging consumers to buy American-made products instead. Key provisions of the proposal include the introduction of a 30 percent duty that will take effect 30 days after the law is enacted. This duty applies to all sheep and lamb products coming from Australia and New Zealand.
