US exports became more attractive to outside demand due to Dollar weakness shrinking the trade gap between exports and imports as imports became more expensive to US consumers.
The deficit, which is the difference between US imports and exports, fell to $30.7bn (£19.3bn) from a revised estimate of $31.9bn in July.
Exports rose slightly on the back of the weak dollar while imports fell.
The dollar has slipped recently, with traders moving into other currencies as the global economy begins to recover.
