Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Contingencies and Commitments Environmental The Company is subject to various federal, state, local and international environmental laws and regulations relating to pollution, protection of public health and the environment, natural resource damages and occupational safety and health. Although compliance with these laws and regulations may affect the costs of the Company's operations, compliance costs to date have not been material. The Company has environmental remediation liabilities at some of its owned operating facilities and has been designated as a PRP with respect to certain third party Superfund waste-disposal sites and other third party-owned sites. The Company accrues amounts for environmental remediation costs that represent management's best estimate of the probable and reasonably estimable future costs related to environmental remediation. During fiscal year 2023 the Company decreased the liability for environmental remediation costs by $1.8 million. During fiscal year 2022, the Company increased the liability for environmental remediation costs by $2.3 million. In December 1997, the Company was named as a party in a Landfill Settlement Agreement related to a third party Superfund waste-disposal site. As a result of this Agreement, the Company was obligated to reimburse the settling work defendants for capital expenditure costs as they were incurred, which was prior to fiscal year 2022. The Company recorded a $2.4 million charge in fiscal year 2022. During fiscal year 2023, the Company paid the liability related to the prior capital expenditure costs and incurred minimal additional costs related to ongoing studies. The Company expects to incur additional claims as a result of this ongoing study that cannot be quantified at this time. During fiscal year 2021 the Company had no change to the liability for environmental remediation costs. The liabilities recorded for environmental remediation costs at Superfund sites, other third party-owned sites and Carpenter-owned current or former operating facilities remaining at June 30, 2023 and 2022 were $16.5 million and $18.3 million, respectively. Additionally, the Company has been notified that it may be a PRP with respect to other Superfund sites as to which no proceedings have been instituted against the Company. Neither the exact amount of remediation costs nor the final method of their allocation among all designated PRPs at these Superfund sites have been determined. Accordingly, at this time the Company cannot reasonably estimate expected costs for such matters. The liability for future environmental remediation costs that can be reasonably estimated is evaluated by management on a quarterly basis. The Company accrues amounts for environmental remediation costs that represent management's best estimate of the probable and reasonably estimable future costs related to environmental remediation. Estimates of the amount and timing of future costs of environmental remediation requirements are inherently imprecise because of the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the identification of currently unknown remediation sites and the allocation of costs among the PRPs. Based upon information currently available, such future costs are not expected to have a material effect on the Company's financial position, results of operations or cash flows over the long-term. However, such costs could be material to the Company's financial position, results of operations or cash flows in a particular future quarter or year. Other The Company is defending various routine claims and legal actions that are incidental to its business and common to its operations, including those pertaining to product claims, commercial disputes, patent infringement, employment actions, employee benefits, compliance with domestic and foreign laws and regulations, personal injury claims and tax issues. Like many other manufacturing companies in recent years, the Company, from time to time, has been named as a defendant in lawsuits alleging personal injury as a result of exposure to chemicals and substances in the workplace such as asbestos. The Company provides for costs relating to these matters when a loss is probable and the amount of the loss is reasonably estimable. The effect of the outcome of these matters on the Company's future results of operations and liquidity cannot be predicted because any such effect depends on future results of operations and the amount and timing (both as to recording future charges to operations and cash expenditures) of the resolution of such matters. While it is not feasible to determine the outcome of these matters, management believes that the total liability from these matters will not have a material effect on the Company's financial position, results of operations or cash flows over the long-term. However, there can be no assurance that an increase in the scope of pending matters or that any future lawsuits, claims, proceedings or investigations will not be material to the Company's financial position, results of operations or cash flows in a particular future quarter or year. The Company has entered into purchase agreements primarily for various key raw materials at market related prices, all made in the normal course of business. The commitments include both fixed and variable price provisions. Raw material prices as of June 30, 2023, were used for commitments with variable pricing. The purchase commitments covered by these agreements aggregate to $178.5 million as of June 30, 2023. Of this amount $171.1 million relates to fiscal year 2024, $4.7 million to fiscal year 2025, $2.1 million to fiscal year 2026, $0.4 million to fiscal year 2027 and $0.2 million to fiscal year 2028.
