Over the past 25 years, U.S.-manufactured goods exports have quadrupled. In 1990, for example, U.S. manufacturers exported $329.5 billion in goods. By 2000, that number had more than doubled to $708.0 billion. In 2014, it reached an all-time high, for the fifth consecutive year, of $1.403 trillion, despite slowing global growth. With that said, a number of economic headwinds have dampened export demand since then, with U.S.-manufactured goods exports down 6.1 percent in 2015 to $1.317 trillion.
