Today, May 5th, President Trump announced by tweet that the additional tariffs on the third group of products from China will increase from 10 percent to 25 percent on Friday, May 10th. The increase had originally been scheduled for earlier this year, but was postponed while trade negotiations with China were ongoing. The tariff numbers for the third group, or tranche, are listed on the following document: https://ustr.gov/sites/default/files/301/2018-0026%20China%20FRN%207-10-2018_0.pdf.
