Abstract: Excerpts from the Introduction: Bulk shipment of raw sugar from Puerto Rico began in 1947 with the opening of the first bulk shipping terminal. Previously, all shipments had been in bags. In 1955, a second bulk shipping terminal was placed in operation; then about one-fourth of the raw sugar produced in Puerto Rico could be shipped in bulk. In 1958 two more terminals were opened, and all Puerto Rican raw sugar was shipped in bulk. During this rapid transition from bagged to bulk handling, Puerto Rican raw sugar producers frequently complained of excessive weight losses during shipment. Producers are paid on the basis of the weight and polarization of each cargo as determined at the unloading port. Weight and polarization usually change in transit. Terminals weigh and determine the polarization of all sugar as they receive it from the mills. In this study, comparisons were made between the total weight and average polarization of sugar received at each terminal during the years 1957 through 1960, and the weight and polarization of the sugar received at mainland ports. The purpose of this study was to determine the extent of the differences in weight and polarization in sugar from the time it was received at the port terminal and when it was received at the mainland refinery and to identify and determine the importance of the major factors accounting for the changes.
