Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Commitments and Contingencies Environmental The Company's operations are subject to extensive and changing federal, state, local and international environmental laws, rules and regulations. The Company's manufacturing sites have an extended history of industrial use, and soil and groundwater contamination have or may have occurred in the past and might occur or be discovered in the future. Environmental efforts are difficult to assess for numerous reasons, including the discovery of new remedial sites, discovery of new information and scarcity of reliable information pertaining to certain sites, improvements in technology, changes in environmental laws and regulations, numerous possible remedial techniques and solutions, difficulty in assessing the involvement of and the financial capability of other potentially responsible parties and the extended time periods over which remediation occurs. Other than the items listed below, the Company is not aware of material environmental liabilities which are probable and estimable. As the Company's environmental contingencies are more clearly determined, it is reasonably possible that amounts may need to be accrued. However, management does not believe, based on current information, that environmental remediation requirements will have a material impact on the Company's results of operations, financial position or cash flows. Future environmental spending is probable at our site in Nashville, TN, the eastern portion of which had been used historically as a landfill, and a western parcel therein, previously acquired from a third party, which reportedly had housed, but no longer does, a fertilizer and pesticide manufacturing facility. We have an estimated liability with a range of $0.9 million-$1.3 million. The remedial action plan for that site has yet to be finalized, and as such, the Company has recorded a liability, which represents the Company's best estimate, of $1.1 million as of March 31, 2017. Litigation 2008 RCRA Civil Enforcement - Geismar, Louisiana plant On January 12, 2017, the Company entered into a settlement with the United States Environmental Protection Agency, or EPA, and the Louisiana Department of Environmental Quality, or LDEQ, with respect to certain manufacturing processes at the Company’s Geismar, Louisiana plant, including the Company’s handling of (i) filter material from an enclosed intermediate filtration step to further process merchant green phosphoric acid, or MGA, that the Company receives as raw material via pipeline from the adjacent site operated by PCS and (ii) the Company’s raffinate co-product that is separated in connection with its PPA production at the plant. The EPA and LDEQ, collectively with the United States Department of Justice, or DOJ, are collectively referred to as the Government Parties. This settlement resulted from years of negotiations between the Company and the Government Parties following several inspections of the plant by the Government Parties in which they raised certain violations of the federal Resource, Conservation and Recovery Act. Prior to this settlement, in the course of discussions with the Government Parties, the EPA and the DOJ required that the Company undertake, as an interim measure, the construction of a new filter unit to replace the enclosed system and allow the removal and separate handling of the filter material. The Company built that unit, which has been operating since 2012. As part of the settlement, Innophos is implementing a deep well injection system, a solution approved by the EPA and LDEQ to handle the raffinate separated at the plant. Such system is expected to be completed by early 2018. The Company previously returned the raffinate to PCS under a long-term contract it has with PCS and can continue to do so until there is a resolution of the deep well system. In connection with this settlement, the Company will pay a $1.4 million civil penalty, which is accrued in other current liabilities. The settlement is currently pending in the United States District Court for the Middle District of Louisiana. Other Legal Matters In July 2013, Innophos, Inc. was assessed approximately $1.2 million of sales/use taxes by the State of Louisiana and Ascension Parish. This tax assessment covers certain raw materials used in the production of Phosphoric Acid. The Company contested both tax assessments. This assessment covers periods 2004 to 2010 for the Parish and 2007 to 2010 for the State. The Company and the respective governmental jurisdictions have reached a settlement in the amount of $0.1 million during the first quarter of 2017. In addition, we are party to legal proceedings and contractual disputes that arise in the ordinary course of our business. Except as to the matters specifically discussed, management believes the likelihood that the ultimate disposition of these matters will have a material adverse effect on our business, results of operations, financial condition and/or cash flows is remote. However, these matters cannot be predicted with certainty and an unfavorable resolution of one or more of them could have a material adverse effect on our business, results of operations, financial condition, and/or cash flows.
