The main purpose of this legislation is to impose additional duties on imported goods entering the United States. The goal is to adjust these duties based on the country's trade balance, which could help manage trade deficits and promote domestic industries. The key provisions of the legislation include a mandatory 10 percent duty on all imports starting from the year the law is enacted. Each subsequent year, the President is required to assess the trade balance from the previous year. If the United States has a trade deficit, the duty will increase by an additional 5 percent.
