Organization, Consolidation and Presentation of Financial Statements [Abstract]
Financial Information	Financial Information The unaudited interim condensed consolidated financial statements of Kewaunee Scientific Corporation (the “Company”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “Commission”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted, although the Company believes that the disclosures are adequate to make the information presented not misleading. These interim condensed consolidated financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of these financial statements and should be read in conjunction with the consolidated financial statements and notes included in the Company’s 2020 Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year. The condensed consolidated balance sheet as of April 30, 2020 included in this interim period filing has been derived from the audited financial statements at that date, but does not include all of the information and related notes required by generally accepted accounting principles ("GAAP") for complete financial statements. The preparation of the interim condensed consolidated financial statements requires management to make certain estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of a good or service promised in a contract (i.e., performance obligation) is transferred to a customer. Control is obtained when a customer has the ability to direct the use of and obtain substantially all of the remaining benefits from that good or service. The majority of the Company’s revenues are recognized over time as the customer receives control as the Company performs work under a contract. However, a portion of the Company’s revenues are recognized at a point-in-time as control is transferred at a distinct point in time per the terms of a contract. Disaggregated Revenue A summary of net sales transferred to customers over time and at a point in time for the periods ended October 31, 2020 and October 31, 2019 is as follows (in thousands): Three Months Ended October 31, 2020 Three Months Ended October 31, 2019 Domestic International Total Domestic International Total Over Time $ 26,950 $ 10,228 $ 37,178 $ 29,950 $ 8,138 $ 38,088 Point in Time 1,822 — 1,822 1,634 — 1,634 $ 28,772 $ 10,228 $ 39,000 $ 31,584 $ 8,138 $ 39,722 Six Months Ended October 31, 2020 Six Months Ended October 31, 2019 Domestic International Total Domestic International Total Over Time $ 56,030 $ 16,593 $ 72,623 $ 58,185 $ 18,187 $ 76,372 Point in Time 2,800 — 2,800 2,686 — 2,686 $ 58,830 $ 16,593 $ 75,423 $ 60,871 $ 18,187 $ 79,058 Contract Balances The closing and opening balances of contract assets arising from contracts with customers which were recorded as unbilled receivables were $8,650,000 at October 31, 2020 and $6,131,000 at April 30, 2020. The closing and opening balances of contract liabilities arising from contracts with customers were $2,768,000 at October 31, 2020 and $2,508,000 at April 30, 2020. The timing of revenue recognition, billings and cash collections results in accounts receivable, unbilled receivables, and deferred revenue which are disclosed in the condensed consolidated balance sheets and in the notes to the condensed consolidated financial statements. In general, the Company receives payments from customers based on a billing schedule established in its contracts. Unbilled receivables represent amounts earned which have not yet been billed in accordance with contractually stated billing terms. Receivables are recorded when the right to consideration becomes unconditional and the Company has a right to invoice the customer. Deferred revenue relates to payments received in advance of performance under the contract. Deferred revenue is recognized as revenue as (or when) the Company performs under the contract. Approximately 100% of the contract liability balances at April 30, 2020 and October 31, 2020 are expected to be recognized as revenue during the respective succeeding 12 months.

The Company has operating type leases for real estate and equipment in both the U.S. and internationally and a financing lease for a truck in the U.S. At October 31, 2020 and April 30, 2020, right-of-use assets totaled $9,157,000 and $9,312,000, respectively. Operating cash paid to settle lease liabilities was $848,000 and $668,000 for the six months ended October 31, 2020 and October 31, 2019, respectively . The Company’s leases have remaining lease terms of up to 10 years. In addition, some of the leases may include options to extend the leases for up to 5 years or options to terminate the leases within 1 year. Operating lease expense was $683,000 for the three months ended October 31, 2020, inclusive of period cost for short-term leases, not included in lease liabilities, of $245,000. Operating lease expense was $1,315,000 for the six months ended October 31, 2020, inclusive of period cost for short-term leases, not included in lease liabilities, of $467,000.

For the finance lease, the remaining lease term was 4.8 years and the discount rate was 10.0%.

Stock Options and Share-based Compensation	Stock Options and Share-based Compensation Compensation costs related to stock options and other stock awards granted by the Company are charged against operating expenses during their vesting period, under ASC 718, "Compensation-Stock Compensation." In May 2020, the Company granted 12,045 RSUs under the 2017 Omnibus Incentive Plan ("2017 Plan"). These RSUs include a service component that vests over a one-year period. The Company granted 83,816 RSUs under the 2017 Omnibus Incentive Plan in June 2020. These RSUs include both a service and a performance component, vesting over a three-year period. The recognized expense is based upon the vesting period for service criteria and estimated attainment of the performance criteria at the end of the three-year period, based on the ratio of cumulative days of service to total days over the three-year period. The Company recorded share-based compensation expense during the three and six months ended October 31, 2020 of $141,000 and $200,000, respectively, with the remaining estimated share-based compensation expense of $990,000 to be recorded over the remaining vesting periods.

Income Taxes	. Income Taxes An income tax benefit of $197,000 and an income tax expense of $2,003,000 were recorded for the three months ended October 31, 2020 and 2019, respectively. An income tax benefit of $176,000 and an income tax expense of $2,172,000 were recorded for the six months ended October 31, 2020 and 2019, respectively. The effective tax rates were 54.4% and 1,267.7% for the three months ended October 31, 2020 and 2019, respectively. The effective tax rates were 18.5% and 428.4% for the six months ended October 31, 2020 and 2019, respectively. The change in the effective tax rate for the three and six-month periods is primarily due to the revocation of the Company's indefinite reinvestment of foreign unremitted earnings position (discussed below) and the impact of foreign operations which are taxed at different rates than the U.S. tax rate of 21%. In addition, the change in the effective tax rates for the three and six months ended October 31, 2020 was impacted by the recording of a Domestic income tax benefit as a result of the Company's current Domestic net loss position. This loss is permitted to be carried back and used to offset Domestic taxable income incurred in previous tax filing periods as allowed by the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The Company’s income tax receivable increased due to the Domestic income tax benefits afforded by the CARES Act to carryback the current Domestic loss and generate an income tax refund. The income tax receivable also includes Domestic income tax benefits attributable to a carryback claim for an applied Research and Development tax credit for the year ended April 30, 2018, as well as the taxable loss generated during the year ended April 30, 2020. In August 2019, the Company revoked its indefinite reinvestment of foreign unremitted earnings position in compliance with ASC 740 "Income Taxes" and terminated its indefinite reinvestment of unremitted earnings assertion for the Singapore, China, and Kewaunee Labway India Pvt. Ltd. international subsidiaries. The Company recognized a tax withholding expense, imposed by the India Income Tax Department in accordance with international tax treaties between the U.S. and Singapore governments, at a rate of 10.0% and 15.0%, respectively. The Company recognized a withholding tax expense of $92,000 and $80,000 for the three and six months ended October 31, 2020, respectively, related to the unremitted earnings of the subsidiaries listed above. The Company recognized a withholding tax expense of $2,083,000 for the three and six months ended October 31, 2019 related to the unremitted earnings of the subsidiaries listed above. The Company has a deferred tax liability of $735,000 and $785,000 for the withholding tax related to Kewaunee Labway India Pvt. Ltd. as of October 31, 2020 and April 30, 2020, respectively. The Company recorded all deferred tax assets and liabilities related to its outside basis differences in its foreign subsidiaries consistent with ASC 740. In July 2020, the U.S. Department of the Treasury issued final tax regulations (proposed regulations were originally published in 2019) with respect to global intangible low-taxed income (''GILTI''.) Among other changes, these regulations now permit an election to exclude, from the GILTI calculation, items of income which are subject to a high effective foreign tax rate. The Company excluded certain items, as permitted by these final regulations, in the current fiscal year and reflected the benefit in the estimated annual effective tax rate.

New Accounting Standards	New Accounting Standards In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments," which replaces the current incurred loss method used for determining credit losses on financial assets, including trade receivables, with an expected credit loss method. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2022. The Company will adopt this standard in fiscal year 2024. The Company does not expect the adoption of this standard to have a significant impact on the Company’s consolidated financial position or results of operations. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment," which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. The Company adopted this standard effective May 1, 2020. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations. In August 2018, the FASB issued ASU 2018-13, "Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC Topic 820. The Company adopted this standard effective May 1, 2020. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations. In August 2018, the FASB issued ASU 2018-14, "Compensation -Retirement Benefits -Defined Benefit Plans -General (Subtopic 715-20) - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans" ("ASU 2018-14"). The amendments in this update remove defined benefit plan disclosures that are no longer considered cost-beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. ASU 2018-14 is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The Company adopted this standard effective May 1, 2020. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations. In December 2019, the FASB issued ASU No. 2019-12, "Income Taxes ("Topic 740"): Simplifying the Accounting for Income Taxes." This update simplifies the accounting for income taxes through certain targeted improvements to various subtopics within Topic 740. The amendments in this update are effective for fiscal years and interim periods beginning after December 15, 2020. The Company expects to adopt this guidance when effective and is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures. In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"). This guidance provides practical expedients for contract modifications and certain hedging relationships associated with the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates. The ASU can be adopted after its issuance date through December 31, 2022. The Company is evaluating the optional expedients and exceptions in the guidance but does not expect the adoption of this standard to have a material impact on its consolidated financial statements.
