Cotton is leading, with 75 percent of its crop being exported each year. The U.S. almond crop, which represents nearly 80 percent of the entire world’s supply, exports rough two-thirds of its crop, while approximately half of the soybean and wheat crops get exported. Pork exports are sitting at 20 percent, corn at 15 percent and beef rounding out the pack with exports around 10 percent.
