Step 1: Identifying the Costing Method:
Paper manufacturing industries adopt Process Costing.
Step 2: Explaining the Manufacturing Flow (Why? - Reason 1):
Paper production is a continuous, sequential chemical and mechanical operation. Wood pulp must pass through several distinct, highly standardized departments (such as Digesting, Bleaching, Beating, Paper-Making, and Finishing) in a fixed order, which aligns perfectly with process-by-process cost tracking.
Step 3: Explaining the Nature of the Output (Why? - Reason 2):
The end product is highly standardized and homogeneous. Because individual sheets or rolls of paper cannot be traced back to separate material shipments or labor runs, managers must average total production costs across the entire volume of output over the period.
