These units will be classified as normal spoilage. They are normal because the number of spoiled units is within the normal amount of spoilage. The fact that they can be sold does not change the fact that they are spoiled units. An example of spoilage that is sold is garments or linens that are sold at a reduced price as "seconds" with the understanding that they are not perfect. Spoilage may also be discarded if there is no market for it. In this question, the number of spoiled units considered normal spoilage is expressed as a percentage of the number of units inspected. The total number of units inspected during the month was all of the units in beginning work-in-process inventory (20,000) plus all of the units transferred in during the month (180,000), as follows: The units are inspected at the 70% point, and the units in BWIP were only 60% complete at the beginning of the month. Therefore, the 20,000 units in BWIP were inspected during the current month. All of the units transferred in (180,000) during the month were also inspected. The transferred-in units that were completed were inspected, and so were the transferred-in units that were still in ending WIP inventory at month end. The units in ending WIP inventory were 80% complete with respect to conversion; and since inspection is done at the 70% point, those units in ending inventory were inspected during the current month. Therefore, 200,000 units (20,000 in BWIP + 180,000 transferred in) were inspected during the period. The allowance for normal spoilage is 4% of the units inspected, so 4% of 200,000, or 8,000 units, would be normal spoilage. Since only 5,000 units were spoiled, all of those 5,000 units are normal spoilage. Waste is material that is left over after production is complete. It has no value. Since these defective units are sold, they are not waste. They are simply spoiled units that have some minimal value. Because the amount of defective units is below the maximum that is considered normal, this is normal spoilage. However, these units have not been reworked. The problem says that the company sells them without any further processing for whatever it can. Because the amount of defective units is less than what is considered normal, this is not abnormal spoilage.
