Tare

in commerce a deduction made from the gross weight of goods as an allowance for the weight of the bag, box, cask, or other package. Farmers marketing wheat in sacks are accustomed to allowing a pound of tare for each sack. In the old arithmetics tare is associated with tret. Tret, now entirely discontinued, was an allowance of four pounds to the hundred to customers who were obliged to transport their wares to great distances. Tret was allowed, no doubt, on the plea that goods would suffer loss in weight or bulk through transportation.
