Analysts said the rise was due to a resumption of cotton shipments from regional neighbours, who traditionally export via the port of Abidjan, as well as deliveries from the cotton campaign currently under way in Ivory Coast.
A post-election conflict in Ivory Coast last year hindered shipping operations for over four months.
Ivory Coast's annual cotton output was around 400,000 tonnes before a 2002-2003 civil war plunged it into nearly a decade of crisis, halving cotton production as a result.
