GOOD DEMAND FOR COLOMBIANS ON BREMEN MARKET The Bremen green coffee market attracted good buying interest for Colombian coffee last week, while Brazils were almost neglected, trade sources said. Buyers were awaiting the opening of Brazil's export registrations for May shipment, which could affect prices for similar qualities, they said. Colombia opened export registrations and good business developed with both the FNC and private shippers. Prices were said to have been very attractive, but details were not immediately available. Central Americans were sought for spot and afloat. In the robusta sector nearby material was rather scarce, with turnover limited, the sources said. The following offers were in the market at the end of last week, first or second hand, sellers' ideas for spot, afloat or prompt shipment in dlrs per 50 kilos fob equivalent, unless stated (previous week's prices in brackets) - Brazil unwashed German quals 100 (102), Colombia Excelso 105 (110), Salvador SHG 110 (108), Nicaragua SHG 109 (same), Guatemala HB 111 (same), Costa Rica SHB 113 (112), Kenya AB FAQ 142 (134), Tanzania AB FAQ 120 (same), Zaire K-5 105 (unq), Sumatra robusta EK-1 91 CIF (same).
