Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Nature of Business	Note 1 – Organization and Nature of Business Smart Sand, Inc. and its subsidiaries (collectively, the “Company”) are headquartered in The Woodlands, Texas, and was incorporated in July 2011. The Company is engaged in the excavation, processing and sale of industrial sand, or proppant, for use in hydraulic fracturing operations for the oil and gas industry. The Company completed construction of the first phase of its primary facility in Oakdale, Wisconsin and commenced operations in July 2012. Immaterial Correction The Company discovered that an immaterial correction should be made relating to the amortization of deferred transaction costs associated with the issuance of shares of the Company’s outstanding Redeemable Series A preferred stock (the “Series A Preferred Stock”). The Company has been amortizing the deferred costs into interest expense from the date of issuance to the mandatory redemption date of the Series A Preferred Stock, which was September 13, 2016. In March 2014, the Company redeemed certain Series A Preferred Stock prior to the mandatory redemption date and wrote off a portion of the transaction costs as part of the early redemption. The Company never adjusted the quarterly amortization amount for the portion previously written off. The Company concluded the amounts were immaterial to its 2016 and 2015 interim financial statements in accordance with the guidance in U.S. Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin (SAB) No. 99 “Materiality” and SAB No. 108 “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in the Current Year Financial Statements.” The correction resulted in a decrease to current liabilities by $861 as of December 31, 2015.
