(3) By customary tare: The weight of standardized package has a generally recognizer weight which can be used to represent the weight of such packages. E.g: The weig

16、ht of a gunny bag is 2.5 pounds.(4) By computed tare: The weight of package is calculated according to the tare previously agreed upon by the seller and the buyer instead of actual weighing.1.
