BRASILIA, July 1 (Reuters) - Brazil posted a $10.4 billion trade surplus in June, figures showed on Thursday, close to the consensus forecast in a Reuters poll for a $10.7 billion surplus and up sharply from a $6.5 billion surplus in the same month last year. Exports in June totaled $28.1 billion and imports were $17.7 billion, the ministry said. That brings the trade surplus in the first half of the year to $37.5 billion, up 68% from the $22.3 billion surplus registered in the same period a year ago.
