The main purpose of this legislation, known as the United States Citrus Protection Act, is to prevent the importation of commercially produced fresh citrus fruit from China into the United States. The objective is to protect the domestic citrus industry from potential threats, which may include pests or diseases that could harm U.S. citrus crops. The key provision of this law is a clear ban on the importation of fresh citrus fruit from China. This means that no commercially produced citrus fruits, such as oranges, lemons, or limes, can be brought into the U.S. from that country.
