The monthly decline was the first time since October 2009.
In the month, imports also dropped 2.43 per cent to $16.87 billion, resulting in a small trade deficit.
Thai exports during the first 11 months grew 19.04 per cent to $211.8 billion. Imports went up by 25.47 per cent to $209.34 billion. The country locked in a trade surplus of $2.46 billion in the first 11 months.
