Exports last month climbed to $27.68 billion, while imports stood at $34.4 billion, narrowing the trade gap to $6.76 billion.
"The trade deficit during the month was the lowest since March 2011. The main reason for decline in imports was a dip in imports of gold and oil," Commerce Secretary SR Rao told reporters here.
Imports of gold and silver plunged more than 80 per cent to $0.8 billion in September from $4.6 billion a year earlier. Oil imports declined by about 6 per cent to $13.19 billion.
During April-September, gold and silver imports rose 8.7 per cent to $23.1 billion.
