The importing of Chinese art from China has been regulated since 2009 by a Memorandum of Understanding (MOU) that is set to be renewed soon, through 2024. It is my opinion, and that of many other experts and commercial & non-profit institutions in the U.S., that this ban is not appropriate. The ban covers virtually all items through the Tang Dynasty and wall decoration and monumental sculpture more than 250 years old.
See the discussion on why this MOU should not be renewed posted by Cultural Property News here.
In addition, "ordinarily, there are no customs duties on art or antiques. It is considered in the public interest to bring art and literature to the U.S., so in the past, no duties were imposed on foreign art or books. The Trump administration is changing that, at least for art and antiques from China. This is one of the more bizarre stories in the tariff saga, since a tariff on antiques will please the Chinese government and reinforce its global dominance and monopoly on Chinese art. Artworks, antiques, and historical and archaeological collections are included in the Trump administration’s proposed 10% retaliatory tariff on an additional $200 billion of China imports....it is clear that the proposed tariff on Chinese art only punishes U.S. collectors, dealers, and art museums – not the Chinese, who requested import restrictions on art and antiques up to 1912 in the first place!" (quoted from Cultural Property News July 19, 2018).
