The main purpose of this legislation is to protect the U.S. citrus industry by banning the importation of commercially produced fresh citrus fruit from China. The objective is to prevent potential threats to domestic agriculture, which could arise from pests or diseases that may accompany imported fruits. The key provision of this law is a clear prohibition on the import of fresh citrus fruits from China. This means that no commercially produced citrus fruit, such as oranges, lemons, or limes, can be brought into the United States from that country.
