The figure compared with a surplus of $14.8 billion in the same month last year, and a median forecast of an $11.9 billion surplus in a poll of 13 economists by Dow Jones Newswires.
Exports fell 18.1 percent to $114.10 billion, while imports were up 10.1 percent to $137.08 billion during the month, which included most of the Lunar New Year holiday, the General Administration of Customs said.
"The Spring Festival factor caused sharp fluctuations in the monthly growth rate as well as the monthly deficit," Customs said in a statement accompanying the data.
Chinese traders followed their "business habit" of bringing forward exports ahead of the holiday, and focusing on imports immediately afterwards, it added.
In the first two months of the year, China's exports were down 1.6 percent year-on-year to $321.23 billion and imports rose 10 percent to $312.34 billion, it said.
The trade surplus in the two-month period narrowed by 79.1 percent on-year to $8.89 billion, it added.
