Inventories, Net

12 Months Ended

Dec. 31, 2024

Inventories are valued at the lower of cost (using the first-in, first-out and weighted average methods) or net realizable value. The Company's costs included in inventory primarily include resins, pulp, chemicals, direct labor, utilities, maintenance, depreciation, finishing supplies and an allocation of certain overhead costs. Machine start-up costs or abnormal machine shutdowns are expensed in the period incurred and are not reflected in inventory. The Company reviews inventories at least quarterly to determine the necessity of write-offs for excess, obsolete or unsalable inventory. The Company estimates write-offs for inventory obsolescence and shrinkage based on its judgment of future realization. These reviews require the Company to assess customer and market demand. There were no material write-offs during the years ended December 31, 2024, 2023, and 2022.
