Chinese imports of dried distillers grains rose 252.5% month on month to 12,894 mt in March from 3,657 mt in February, Chinese Customs Information Center data showed Wednesday.
March's imports had a total value of $2.775 million, according to the customs agency data, up 231.7% from $836,584 in February.
Imports fell 85.6% by volume and 82.1% by value compared with March 2017's 89,761 mt and $15.548 million, the data show.
Chinese DDGS imports in the first three months of 2018 totaled 25,093 mt, down 87.1% compared with 194,632 mt in the year-ago period.
Almost all March's imports came from the US, with a total of 12,893 mt. The remainder, 100 kg, came from Japan.
China used to be the largest buyer of US DDGS, but in September 2016 it imposed a preliminary 33.8% antidumping duty on US DDGS. It then announced a preliminary anti-subsidy tariff of 10%-10.7%.
China announced its final rule in January 2017, increasing antidumping duties to 42.2%-53.7% and its anti-subsidy duties to 11.2%-12.0%.
China removed its 11% value-added tax on imported DDGS in November 20 2017, but antidumping and anti-subsidy duties are still in place.
DDGS are a co-product of ethanol production and are used for livestock feed in domestic and foreign feedlots.
