A press release by the U.S. Office of the United States Trade Representative (USTR) discusses the new trade tariffs poised to be imposed on China by the U.S. on June 15th, 2018 and approved by President Trump; the tariffs are of "25 percent on approximately $50 billion worth of Chinese imports containing industrially significant technologies, including those related to China's 'Made in China 2025' industrial policy."

The press release also links to two PDFs (List 1.pdf and List 2.pdf) that in combination specify the types of Chinese products affected by the new tariffs. (The term "nesoi" commonly found in the lists stands for "not elsewhere specified or included.")

Optics and photonics to be under tariff
Of high relevance to the Laser Focus World audience are the various optics and photonics products on the lists. The Chinese products on the two U.S. government lists that are of interest to our audience include (not necessarily in order, and not necessarily a complete list):
