BRAZIL COULD EXPORT 19 MLN BAGS OF COFFEE -IBC Brazil's coffee exports could amount to 19 mln bags this year, because of the excellent crop estimate of 35.2 mln bags, an IBC spokesman said. He said exports could surpass the average annual 18 mln bags mark, especially if the final harvest to be conducted in October and November confirms the crop at over 35 mln bags. He said the average limit of errors for the official crop harvest could be set at five pct above or below the first estimates officially published today. He said the IBC agreed with a request by producers for the Institute to ask the government for a monthly indexation of the guarantee minimum price.
