BEIJING, Sept. 11 -- China on Wednesday unveiled the first set of lists of U.S. goods to be excluded from the first round of additional tariffs on U.S. products.

The exemption will be effective from Sept. 17, 2019 to Sept. 16, 2020, the Customs Tariff Commission of the State Council said in a statement.

Two lists of goods will be excluded from China's first round of tariff countermeasures against the U.S. Section 301 measures.

The first list includes 12 items and allows affected import enterprises to apply for refunds of collected duties within six months from Wednesday.

The second list includes four items that will enjoy the exemption but are not eligible for tariff refunds.

Next, the commission will continue to work on the exemption process and release subsequent lists in due course, according to the statement.
