Business Combination and Asset Acquisition [Abstract]
Business Acquisitions	Business Acquisitions Previous Acquisitions In October 2022, the Company acquired a business that provides pickling and rinsing products and services, which is part of the EMEA reportable segment, for approximately 3.5 million EUR or approximately $3.5 million. This acquisition, along with the Company’s January 2022 acquisition in the Americas (described below), which had similar specializations and product offerings in pickling inhibitor technologies, strengthens Quaker Houghton’s position in pickling inhibitors and additives, enabling the Company to better support and optimize production processes for customers across the metals industry. As of September 30, 2023, the allocation of the purchase of this acquisition has been finalized. In January 2022, the Company acquired a business that provides pickling inhibitor technologies, drawing lubricants and stamping oil, and various other lubrication, rust preventative, and cleaner applications, which is part of the Americas reportable segment, for approximately $8.0 million. This business broadens the Company’s product offerings within its existing metals and metalworking business in the Americas region. During the third quarter of 2022 the Company finalized post-closing adjustments that resulted in the Company paying less than $0.1 million of additional purchase consideration. Also in January 2022, the Company acquired a business related to the sealing and impregnation of metal castings for the automotive sector, as well as impregnation resin and impregnation systems for metal parts, which is part of the EMEA reportable segment, for approximately 1.2 million EUR or approximately $1.4 million. This business broadens its product offerings and service capabilities within its existing impregnation business. The allocation of the purchase prices of both of these January 2022 acquisitions have been finalized. In November 2021, the Company acquired Baron Industries, a privately held company that provides vacuum impregnation services of castings, powder metals and electrical components for its Americas reportable segment for $11.0 million, including an initial cash payment of $7.1 million, subject to post-closing adjustments, as well as certain earn-out provisions that are payable at various times from 2022 through 2025. The earn-out provisions could total a maximum of $4.5 million. As of September 30, 2023, the Company has remaining earn-out liabilities recorded on its Condensed Consolidated Balance Sheet of $1.1 million. Additionally, during the third quarter of 2022 the Company finalized post-closing adjustments that resulted in the Company receiving a payment of less than $0.1 million. In December 2020, the Company acquired Coral Chemical Company, LLC (“Coral”), a privately held U.S.-based provider of metal finishing fluid solutions. Subsequent to the acquisition, the Company and the sellers of Coral (the “Sellers”) have worked to finalize certain post-closing adjustments. During the second quarter of 2022, after failing to reach resolution, the Sellers filed suit asserting certain amounts owed related to tax attributes of the acquisition. During the first nine months of 2023, there have been no material changes to the facts and circumstances of the claim asserted by the Sellers, and the Company continues to believe the potential range of exposure for this claim is $0 to $1.5 million.
