They were the first phase of U.S. tariffs in the trade conflict with China. As previously announced by the Trump administration in late 2018, injection molds are exempted. The Sept. 20 lists include injection molds, mold inserts, mold bases and mold base parts from China, along with specialized equipment like some types of vertical or single-shaft shredders for recycling. At times the exempted products go into granular detail. The exemptions from the July 2018 list include very specific descriptions of PVC sheet of certain widths, for example, and polyacetal brackets, filters or hose fittings, as well as industrial-sized plates of ethylene-vinyl acetate and PE foam. 1...
