The White House officially announced that retaliatory tariffs will be imposed on 818 HTS lines, with collection of the additional 25% duties beginning July 6. At the same time, an additional 284 tariff lines are being proposed, but will first undergo a public comment process. The targeted products fall primarily in aerospace, automobile, industrial machinery, information technology and robotics industries. The U.S. Trade Representative announced it will establish a process for U.S. companies to request exclusion from the tariffs on specific products if no alternative supplier exists.
