Inventory Disclosure [Text Block] | 4. INVENTORIES ​ We state our inventories at the lower of cost or market, with cost determined using average cost, last-in first-out (“LIFO”) and first-in first-out methods for different components of inventory. Inventories consisted of the following (dollars in millions): ​
|  | September 30, |  |  | December 31, |
|  | 2023 |  |  | 2022 |
Raw materials and supplies |  | $ | 221 |  |  | $ | 241 |
Work in progress |  |  | 42 |  |  |  | 40 |
Finished goods |  |  | 716 |  |  |  | 758 |
Total |  |  | 979 |  |  |  | 1,039 |
LIFO reserves |  |  | (38 | ) |  |  | (44 | )
Net inventories |  | $ | 941 |  |  | $ | 995 |
​ For both September 30, 2023 and December 31, 2022, approximately 8% of inventories were recorded using the LIFO cost method. ​
