China on Wednesday moved to exempt 16 types of US products from additional retaliatory tariffs, including whey and fish meal, which are fed to animals, and some lubricants, according to a statement from the Ministry of Finance.

The exemption will take effect on September 17 and be valid for a year through to Sept. 16, 2020.

The ministry said items on the two tariff exemption lists posted on its website will not be subject to additional duties imposed by China on US goods "as countermeasures to US Section 301 measures," it said.
