On August 14, 2019, the U.S. Trade Representative (USTR) announced the implementation of additional 10% duties on China Section 301 List 4 covering $300 billion in Chinese imports. On Aug 30th, the additional rate for these lists was increased to 15%. The new section 301 List 4 has been divided into 2 parts, with the first (4A) set to go into effect on September 1st, 2019 and the second (4B) delayed till December 15th, 2019 to avoid hurting retailers for the Christmas shopping season.
We have an updated document that details all the information about the China penalty tariffs including these 2 new lists.

Note that at this time these additional codes and rates are not present in our duty/tariff products because the implementation dates are still in the future and it is possible things could change. When they become official, we will include in our data and web site products.
