Accounting Policies [Abstract]
ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES	ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES CSW Industrials, Inc. (“CSWI,” “we,” “our” or “us”) is a diversified industrial growth company with a strategic focus on providing niche, value-added products in the end markets we serve. We operate in three business segments: Contractor Solutions, Specialized Reliability Solutions and Engineered Building Solutions. Our products include mechanical products for heating, ventilation, air conditioning and refrigeration ("HVAC/R"), plumbing products, grilles, registers and diffusers ("GRD"), building safety solutions and high-performance specialty lubricants and sealants. End markets that we serve include HVAC/R, architecturally-specified building products, plumbing, general industrial, energy, rail transportation and mining. Our manufacturing operations are concentrated in the United States (“U.S.”), Vietnam and Canada, and we have distribution operations in the U.S., Australia, Canada and the United Kingdom (“U.K.”). Our products are sold directly to end users or through designated channels in over 100 countries around the world, primarily including the U.S., Canada, the U.K. and Australia. Drawing on our innovative and proven technologies, we seek to deliver solutions primarily to contractors that place a premium on superior performance and reliability. We believe our brands are well-known in the specific end markets we serve and have a reputation for high quality. The reputation of our product portfolio is built on more than 100 well-respected brand names, such as AC Guard TM , Air Sentry®, Cover Guard TM , Deacon®, Falcon Stainless®, Greco®, Jet-Lube®, Kopr-Kote®, Leak Freeze®, Metacaulk®, No. 5®, OilSafe®, Safe-T-Switch®, Shoemaker Manufacturing®, Smoke Guard®, TRUaire® and Whitmore®. These products are distributed through an extensive wholesale distribution network serving the HVAC/R, architecturally-specified buildings products, plumbing, general industrial, energy, rail transportation and mining end markets. Our desire to develop solutions for our contractors, combined with the differentiated nature of our niche product offerings, drives loyalty to our brands. We rely on both organic growth and inorganic growth through acquisitions to provide an increasingly broad portfolio of performance optimizing solutions that meet our customers’ ever-changing needs. We have a successful record of making attractive and synergistic acquisitions that support expansion of our broad portfolio of solutions, and we remain focused on identifying additional acquisition opportunities in our core end markets. We continue to assess and proactively manage the impacts of COVID-19 on all aspects of our business and geographies, including with respect to our employees, customers and communities and supply chain. During the three months ended June 30, 2023, the COVID-19 pandemic had no direct or indirect material impact on our consolidated operating results. While the Federal COVID-19 Public Health Emergency Declaration expired on May 11, 2023, the extent to which the COVID-19 pandemic may impact our business, results of operations, and financial condition will depend on future developments, which are uncertain and cannot be predicted. We continue to monitor the Russian invasion of Ukraine and its global impact. We have no operations, employees or assets in Russia, Belarus or Ukraine, nor do we source goods or services of any material amount from those countries, whether directly or indirectly. Since shortly after the Russian invasion of Ukraine began in February 2022, we have had no commercial activities including sales in Russia, Belarus or Ukraine. While the conflict continues to evolve and the outcome remains highly uncertain, we do not currently believe the Russia-Ukraine conflict will have a material impact on our business and results of operations. However, if the Russia-Ukraine conflict continues or worsens, leading to greater global economic or political disruptions and uncertainty, our business and results of operations could be materially impacted as a result. Basis of Presentation The condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2023 (“Quarterly Report”), include all revenues, costs, assets and liabilities directly attributable to CSWI and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The condensed consolidated financial statements are for us and our consolidated subsidiaries, each of which is a wholly-owned subsidiary, except our 50% investment in a variable interest entity ("VIE") for which we have determined that we are the primary beneficiary and therefore have consolidated into our financial statements. All significant intercompany transactions have been eliminated in consolidation. The condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSWI’s financial position as of June 30, 2023, and the results of operations for the three-month period ended June 30, 2023 and 2022. All adjustments are of a normal, recurring nature. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSWI’s Annual Report on Form 10-K for the fiscal year ended March 31, 2023 (the “Annual Report”). Accounting Policies We have consistently applied the accounting policies described in our Annual Report in preparing these condensed consolidated financial statements. Accounting Developments There were not any recently adopted or newly issued accounting pronouncements for the three months ended June 30, 2023, that have had, or are expected to have, a material impact on our consolidated financial statements and disclosures.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS Cover Guard, Inc. and AC Guard, Inc. On July 8, 2022, we acquired the assets of Cover Guard, Inc. (“CG”) and AC Guard, Inc. ("ACG"), based in Orlando, Florida, for an aggregate purchase price of $18.4 million, comprised of cash consideration of $18.0 million and additional contingent considerations initially measured at $0.4 million based on CG and ACG meeting defined financial targets over a period of 5 years. In conjunction with the acquisition, we agreed to pay an additional $3.7 million, comprised of cash consideration of $1.5 million and 5-year annuity payments (value of $2.2 million) to a third party to secure the related intellectual property. The total cash consideration at closing of $19.5 million was funded with cash on hand and borrowings under our existing Revolving Credit Facility (as defined in Note 7). CG and ACG product lines further expand Contractor Solutions’ offering of leading HVAC/R accessories. Through these differentiated products, our Contractor Solutions segment expects to achieve incremental ductless and ducted HVAC/R market penetration. As of the acquisition date, the estimated fair value of the contingent consideration was classified as a long-term liability of $0.4 million and was determined using an option pricing model simulation that determines an average projected payment value across numerous iterations. The CG and ACG acquisition was accounted for as a business combination under FASB Accounting Standards Codification Topic 805 ("Topic 805"). The excess of the purchase price over the preliminary fair value of the identifiable assets acquired was $1.8 million allocated to goodwill, which represents the value expected to be obtained from owning products that are complementary to our existing HVAC/R and plumbing offerings and provide a meaningful value proposition to our end use customers. The preliminary allocation of the fair value of the assets acquired included customer lists ($9.8 million), patent ($1.8 million), trademarks ($0.7 million), inventory ($3.1 million), accounts receivable ($0.9 million) and equipment ($0.3 million). Customer lists and patents are being amortized over 15 years and 10 years, respectively, while trademarks and goodwill are not being amortized. The Company's evaluation of the facts and circumstances available as of July 8, 2022, to assign fair values to assets acquired is ongoing. We expect to finalize the purchase price allocation as soon as practicable, but no later than one year from the acquisition date. Goodwill and all intangible assets, including customer lists, trademarks and patent are deductible and amortized over 15 years for income tax purposes. CG and ACG activity has been included in our Contractor Solutions segment since the acquisition date. No pro forma information has been provided due to immateriality. The additional $3.7 million we agreed to pay a third party was accounted for as an acquisition of intellectual property and will be amortized over 15 years. Falcon Stainless, Inc. On October 4, 2022, we acquired 100% of the outstanding equity of Falcon Stainless, Inc. ("Falcon"), based in Temecula, California, for an aggregate purchase price of $37.1 million (including $1.0 million cash acquired), comprising cash consideration of $34.6 million and an additional payment of $2.5 million due one-year from the acquisition date assuming certain business conditions are met. The cash consideration was funded with cash on hand and borrowings under our existing Revolving Credit Facility (as defined in Note 7). Falcon products are well-known among the professional trades for supplying enhanced water flow delivery and increased customer satisfaction and supplement our Contractor Solutions segment's existing product portfolio. The Falcon acquisition was accounted for as a business combination under Topic 805. The excess of the purchase price over the preliminary fair value of the identifiable assets acquired was $17.5 million allocated to goodwill, which represents the value expected to be obtained from owning products that are complementary to our existing plumbing offerings and provide a meaningful value proposition to our end use customers. The preliminary allocation of the fair value of the assets acquired comprises customer lists ($17.7 million), trademarks ($4.7 million), accounts receivable ($1.4 million), cash ($1.0 million), inventory ($0.7 million), other current asset ($0.1 million) and other assets ($3.2 million), net of current liabilities (0.7 million) and other liabilities ($8.5 million). Customer lists are being amortized over 15 years, while trademarks and goodwill are not being amortized. The Company's evaluation of the facts and circumstances available as of October 4, 2022, to assign fair values to assets acquired is ongoing. We expect to finalize the purchase price allocation as soon as practicable, but no later than one year from the acquisition date. Goodwill and all intangible assets are not deductible for income tax purposes. Falcon activity has been included in our Contractor Solutions segment since the acquisition date. No pro forma information has been provided due to immateriality.

CONSOLIDATION OF VARIABLE INTEREST ENTITIES AND REDEEMABLE NONCONTROLLING INTEREST	CONSOLIDATION OF VARIABLE INTEREST ENTITY AND REDEEMABLE NONCONTROLLING INTEREST Whitmore Joint Venture On April 1, 2021, Whitmore Manufacturing, LLC (“Whitmore”), a wholly-owned subsidiary of CSWI, completed the formation of the joint venture (the "Whitmore JV") with Pennzoil-Quaker State Company dba SOPUS Products (“Shell”), a wholly-owned subsidiary of Shell Oil Company that comprises Shell’s U.S. lubricants business. The Whitmore JV is deemed to be a VIE as the equity investors at risk, as a group, lack the characteristics of a controlling financial interest. The major factor that led to the conclusion that the Company is the primary beneficiary of this VIE is that Whitmore has the power to direct the most significant activities due to its ability to direct the manufacturing decisions of the Whitmore JV. Whitmore JV's total net assets are presented below (in thousands): June 30, 2023 Cash $ 4,946 Accounts receivable, net 6,653 Inventories, net 4,320 Prepaid expenses and other current assets 329 Property, plant and equipment, net 13,515 Intangible assets, net 6,276 Other assets 275 Total assets $ 36,314 Accounts payable $ 4,955 Accrued and other current liabilities 1,546 Other long-term liabilities 190 Total liabilities $ 6,691 During the three months ended June 30, 2023, the Whitmore JV generated net income of $0.9 million. The Whitmore JV's LLC Agreement contains a put option that gives either member the right to sell its 50% equity interest in the Whitmore JV to the other member at a dollar amount equivalent to 90% of the initiating member's equity interest determined based on the fair market value of the Whitmore JV's net assets. This put option can be exercised, at either member's discretion, by providing written notice to the other member during the month of July 2024 and every two years afterwards. This redeemable noncontrolling interest is recorded at the higher of the redemption value or carrying value each reporting period. Changes in redeemable noncontrolling interest for the three-month period ended June 30, 2023 were as follows (in thousands): Balance at March 31, 2023 $ 18,464 Net income attributable to redeemable noncontrolling interest 445 Balance at June 30, 2023 $ 18,909

Performance-based awards accrue dividend equivalents, which are settled upon (and to the extent of) vesting of the underlying award and do not have the right to vote until vested. Performance-based awards are earned upon the achievement of objective performance targets and are payable in common shares. Compensation expense is calculated based on the fair market value as determined by a Monte Carlo simulation and is recognized over a 36-month cliff vesting period. We granted 29,120 and 21,087 awards with performance-based vesting provisions during the three months ended June 30, 2023 and 2022, respectively, with a vesting range of 0%-200%.

LONG-TERM DEBT	LONG-TERM DEBT Debt consists of the following (in thousands): June 30, 2023 March 31, 2023 Revolving Credit Facility, interest rate of 6.72% and 6.21% (a) $ 210,000 $ 253,000 Less: Current portion — — Long-term debt $ 210,000 $ 253,000 (a) Represents the interest rate effective on June 30, 2023, and March 31, 2023, respectively, excluding the impact from the interest rate swap. Revolving Credit Facility As discussed in Note 8 to our consolidated financial statements included in our Annual Report, prior to May 2021, we maintained a five-year, $300.0 million revolving credit facility agreement (the "First Credit Agreement"), which was scheduled to mature on September 15, 2022. On May 18, 2021, we entered into a Second Amended and Restated Credit Agreement (the “Second Credit Agreement”), which replaced the First Credit Agreement and provides for a $400.0 million revolving credit facility that contains a $25.0 million sublimit for the issuance of letters of credit and a $10.0 million sublimit for swingline loans, with an additional $150 million accordion feature. The Second Credit Agreement is scheduled to mature on May 18, 2026. The Company incurred a total of $2.3 million in underwriting fees, which are being amortized over the life of the Second Credit Agreement. Borrowings under the Second Credit Agreement bear interest at either base rate plus between 0.25% to 1.5% or LIBOR plus between 1.25% to 2.5%, based on the Company’s leverage ratio calculated on a quarterly basis. The base rate is described in the Second Credit Agreement as the highest of (i) the Federal funds effective rate plus 0.50%, (ii) the prime rate quoted by The Wall Street Journal, and (iii) the one-month LIBOR rate plus 1.00%. We pay a commitment fee between 0.15% to 0.4% based on the Company's leverage ratio for the unutilized portion of this facility. Interest and commitment fees are payable at least quarterly and the outstanding principal balance is due at the maturity date. The Second Credit Agreement is secured by a first priority lien on all tangible and intangible assets and stock issued by the Company and its domestic subsidiaries, subject to specified exceptions, and 65% of the voting equity interests in its first-tier foreign subsidiaries. On December 15, 2022, the Company entered into an Incremental Assumption Agreement No. 1 and Amendment No. 2 to the Second Credit Agreement (the “Second Amendment”) to utilize a portion of the accordion feature, thus increasing the commitment from $400.0 million to $500.0 million, and concurrently reduced the available incremental accordion by a corresponding amount (the term "Revolving Credit Facility" as used throughout this document refers to the First Credit Agreement, the Second Credit Agreement and the Second Amendment, as applicable). The Second Amendment also replaced the LIBOR Rate with individualized metrics based on the specific denomination of borrowings, including a metric based on Term SOFR (as defined in the Second Credit Agreement) for borrowings denominated in U.S. Dollars. The Company incurred a total of $0.3 million in underwriting fees, which are being amortized over the remaining term of the Second Credit Agreement. During the three months ended June 30, 2023, we borrowed $15.4 million and repaid $58.4 million under the Revolving Credit Facility. As of June 30, 2023 and March 31, 2023, we had $210.0 million and $253.0 million, respectively, in our outstanding balance, which resulted in borrowing capacity under the Revolving Credit Facility of $290.0 million and $247.0 million, respectively. The financial covenants contained in the Second Credit Agreement require the maintenance of a maximum leverage ratio of 3.00 to 1.00, subject to a temporary increase to 3.75 to 1.00 for 18 months following the consummation of permitted acquisitions with consideration in excess of certain threshold amounts set forth in the Second Credit Agreement. The Second Credit Agreement also requires the maintenance of a minimum fixed charge coverage ratio of 1.25 to 1.00, the calculations and terms of which are defined in the Second Credit Agreement. Covenant compliance is tested quarterly, and we were in compliance with all covenants as of June 30, 2023. Interest payments on the first $100.0 million borrowing under the Revolving Credit Facility are hedged under an interest rate swap agreement as described in Note 9. Whitmore Term Loan Prior to January 20, 2023, Whitmore maintained a secured term loan (the "Whitmore Term Loan") related to a warehouse and corporate office building and the remodel of an existing manufacturing and research and development facility. The Whitmore Term Loan required payments of $0.1 million each quarter. Borrowings under this term loan bore interest at a rate of one month LIBOR plus 2.0%. On January 20, 2023, the Whitmore Term Loan was paid off using borrowings under our existing Revolving Credit Facility discussed above. As such, as of June 30, 2023 and March 31, 2023, there were no outstanding principal amounts under the Whitmore Term Loan. Interest payments under the Whitmore Term Loan were hedged under an interest rate swap agreement until January 9, 2023, when the interest rate swap agreement was terminated.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGE ACCOUNTING	DERIVATIVE INSTRUMENTS AND HEDGE ACCOUNTING We enter into interest rate swap agreements to hedge exposure to floating interest rates on certain portions of our debt. All interest rate swaps are highly effective. Prior to January 9, 2023, we had an interest rate swap entered to hedge our exposure to variability in cash flows from interest payments on our Whitmore Term Loan. On January 9, 2023, this interest rate swap was terminated when the loan was paid off and resulted in a cash receipt of $0.2 million. On February 7, 2023, we entered into an interest rate swap to hedge our exposure to variability in cash flows from interest payments on the first $100.0 million borrowing under our Revolving Credit Facility. This interest rate swap fixes the one-month SOFR rate at 3.85% for the first $100.0 million borrowing under our Revolving Credit Facility and will expire May 18, 2026. As of June 30, 2023 and March 31, 2023, we had $100.0 million and $100.0 million, respectively, of notional amount in outstanding designated interest rate swaps with third parties. The fair value of the interest rate swap designated as a hedging instrument is summarized below (in thousands): June 30, 2023 March 31, 2023 Current derivative asset $ 1,472 $ 877 Non-current derivative asset 260 — Non-current derivative liabilities — 1,021 The impact of changes in fair value of the interest rate swap is included in Note 15.

On October 30, 2020, we announced that our Board of Directors authorized a new program to repurchase up to $100.0 million of our common stock, which replaced the prior announced $75.0 million program. On December 16, 2022, we announced that our Board of Directors authorized a new $100.0 million share repurchase program, which replaced the previously announced $100.0 million program. Under the current repurchase program, shares may be repurchased from time to time in the open market or in privately negotiated transactions. Repurchases will be made at our discretion, based on ongoing assessments of the capital needs of the business, the market price of our common stock and general market conditions. Our Board of Directors has established an expiration date of December 31, 2024, for completion of the current repurchase program; however, the program may be limited or terminated at any time at our discretion without notice. As of June 30, 2023, no shares have been repurchased under the current $100.0 million repurchase program. Under the prior $100.0 million repurchase program, no shares were repurchased during the three months ended June 30, 2023 and 287,990 shares were repurchased during the three months ended June 30, 2022 for $30.5 million.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The fair value of the interest rate swap contract (as discussed in Note 9) is determined using Level 2 inputs. The carrying value of our debt (discussed in Note 7) approximates fair value as it bears interest at variable rates. The carrying amounts of other financial instruments (i.e., cash and cash equivalents, accounts receivable, net, accounts payable) approximate their fair values as of June 30, 2023 and March 31, 2023 due to their short-term nature. The redeemable noncontrolling interest is recorded at the higher of the redemption value or carrying value each reporting period. The redemption value of the redeemable noncontrolling interest is estimated using a discounted cash flow analysis, which requires management judgment with respect to future revenue, operating margins, growth rates and discount rates and is classified as Level III under the fair value hierarchy. The redemption value of the redeemable noncontrolling interest is discussed in Note 3.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended June 30, 2023, we earned $41.5 million from operations before taxes and provided for income taxes of $10.5 million, resulting in an effective tax rate of 25.2%. The provision for income taxes differed from the statutory rate for the three months ended June 30, 2023 primarily due to state income tax (net of federal benefit), executive compensation limitations, stock-based compensation deferred tax asset ("DTA") write-offs, and provision for global intangible low-taxed income ("GILTI"); offset by excess tax deductions related to Foreign-derived intangible income ("FDII"), non-controlling interest, foreign tax credits and R&D credits. In connection with the TRUaire acquisition that closed in December 2020, the Company recognized an uncertain tax position ("UTP") of $17.3 million related to pre-acquisition tax periods. In addition, in accordance with the tax indemnification included in the purchase agreement, the seller provided a contractual indemnification to the Company for up to $12.5 million related to UTPs taken in pre-acquisition years and we recognized a tax indemnification asset of $12.5 million. This tax indemnification asset will either be settled or expire by December 2023. During the three months ended March 31, 2021, as a result of the audit closure of a pre-acquisition tax period for TRUaire, $5.0 million of the tax indemnification asset was released along with the relevant UTP of $5.3 million. During the three months ended December 31, 2022, TRUaire's Vietnam entity concluded its audit for the tax periods from January 1, 2019 to March 31, 2022 and received an audit closing letter from the tax authority. As a result, $1.5 million of the UTP accrual (including penalties and interests accrued post-acquisition) was released and recorded as an income tax benefit for the three months ended December 31, 2022. The remaining UTP accrual will be released upon the closure of the tax statutes. As of June 30, 2023, $7.5 million of the tax indemnification asset remains outstanding and is reported in our condensed consolidated balance sheets in prepaid expenses and other current assets. In connection with the Falcon acquisition that closed in July 2022, the Company recognized a UTP of $3.1 million related to pre-acquisition tax periods. In addition, in accordance with the tax indemnification included in the purchase agreement, the sellers provided a contractual indemnification to the Company for up to $4.5 million related to UTPs taken in pre-acquisition years, and we recognized an initial tax indemnification asset of $3.1 million through purchase accounting, which will increase as additional interest and penalties on UTPs are accrued. This tax indemnification asset will either be settled or expire upon the closure of the tax statutes for the pre-acquisition periods. As of June 30, 2023, the UTP and the offsetting tax indemnification asset were $3.4 million, and $1.1 million of the UTP and the related tax indemnification asset are expected to expire in October 2023, upon the closure of the tax statutes. As of June 30, 2023, $1.1 million of the tax indemnification assets is reported in our condensed consolidated balance sheets in prepaid expenses and other current assets. For the three months ended June 30, 2022, we earned $39.3 million from operations before taxes and provided for income taxes of $9.6 million, resulting in an effective tax rate of 24.5%. The provision for income taxes differed from the statutory rate for the three months ended June 30, 2022 primarily due to state income tax (net of federal benefit), executive compensation limitations, provision for global intangible low-taxed income ("GILTI") and an increase in the reserves for uncertain tax provisions; offset by excess tax deductions related to Foreign-derived intangible income ("FDII"), excess tax deductions related to stock compensation, foreign tax credits and impact of noncontrolling interest ("NCI"). One of our Canadian subsidiaries received proposed assessments resulting from audits by the taxing authority for tax years 2017-2020, and we have included the impact of the proposed assessments in the income tax expense for the three months ended June 30, 2023.
