All three major indexes were down about 2 percent just after the start of trading.
China's official manufacturing Purchasing Managers' Index (PMI) fell to 49.7 in August from 50.0 in July.
"With the weak data coming out, we're going to see the negative sentiment from the last few weeks continuing."
Adding to the nervousness, International Monetary Fund head Christine Lagarde said global economic growth was now likely to be weaker than had been expected just a few months ago.
At 9:42 a.m. ET (1342 GMT) the Dow Jones industrial average was down 344.01 points, or 2.08 percent, at 16,184.02. The S&P 500 was down 39.55 points, or 2.01 percent, at 1,932.63 and the Nasdaq composite was down 85.37 points, or 1.79 percent, at 4,691.14.
All the 10 major S&P sectors were lower with the energy index's 2.93 percent fall leading the decliners. Oil prices fell more than 4 percent, snapping three days of strong gains, after the weak data from China. Oil majors Chevron and Exxon were down about 3 percent.
The Institute for Supply Management's index of U.S. factory activity is due at 10 a.m. ET (1400 GMT) and is expected to have slipped to 52.6 in August from 52.7 in July.
Netflix was down 4.4 percent at $109.94 after Variety reported that Apple was looking to move into the original programming business to compete with video streaming companies. Apple fell 1.3 percent to $111.39.
The S&P 500 index showed no new 52-week highs and seven new lows, while the Nasdaq recorded four new highs and 17 new lows.
