A lumber mill typically produces lumber products in large quantities and often follows a continuous production process rather than manufacturing products based on specific customer orders or specifications. In a lumber mill, the production process usually involves continuous operations where raw materials are processed into finished lumber products without significant customization for individual customer orders. This continuous production process is more aligned with process costing rather than job order costing. However, if a lumber mill also produces custom or specialty lumber products based on specific customer orders or specifications, then job order costing might be appropriate for those particular customized products. Therefore, while job order costing could potentially be used in certain scenarios within a lumber mill, it might not be the primary costing method for the overall operations of the mill
