      abstract = {Excerpts from the report Introduction:  Sugar is the  principal commodity exported from Puerto Rico.  More than a  million tons, representing 90 to 95 percent of the total  production of the island, are shipped to continental United  States each year.  The mainland United States receives  about one-eighth of its sugar requirements from Puerto  Rico.  Approximately 90 percent of the total shipments to  mainland ports from this source is in the form of raw  sugar.  This raw sugar is sold to mainland refiners on the  basis of the weight and polarization of the sugar when  delivered.  During the past few years producers have been  concerned about decreases in weight and polarization of raw  sugar between the time it is produced and its arrival at  mainland ports.  The general belief throughout much of the  Puerto Rican sugar industry is that losses of weight in raw  sugar shipped to the United States, especially to northern  ports, are excessive and that there is no gain in  polarization on most shipments to offset the weight loss.   The Puerto Rican sugar industry, therefore, requested that  a study be made of the losses of raw sugar in storage and  shipment.},
