Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation and Summary of Significant Accounting Policies The unaudited consolidated financial statements of Harvard Bioscience, Inc. and its wholly-owned subsidiaries (collectively, Harvard Bioscience or the Company) as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. The December 31, 2020, consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020. In the opinion of management, all adjustments, which include normal recurring adjustments necessary to present a fair statement of financial position as of September 30, 2021, results of operations and comprehensive income (loss) and cash flows for the three months and nine months ended September 30, 2021 and 2020, as applicable, have been made. The results of operations for the three months and nine months ended September 30, 2021, are not necessarily indicative of the operating results for the full fiscal year or any future periods. The accounting policies underlying the accompanying unaudited consolidated financial statements are those set forth in Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. There have been no material changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2021.
Risks and Uncertainties Policy [Policy Text Block] | Risks and Uncertainties On March 11, 2020, the World Health Organization declared the outbreak of a novel coronavirus (COVID-19) as a pandemic. The COVID-19 pandemic has had a negative impact on the Company’s operations to date and the future impacts of the pandemic and any resulting economic impact are largely unknown and rapidly evolving. Since the global outbreak of COVID-19, many customers, particularly academic research institutions, have reduced laboratory work which has negatively impacted, and will continue to negatively impact, the Company’s sales. While many of the Company's customers, including academic labs, have reopened, a significant number of them remained closed or at significantly lower capacity levels through the third quarter of 2021. Additionally, to ensure business continuity while maintaining a safe environment for employees aligned with guidance from government and health organizations, the Company transitioned a significant portion of its workforce to work-from-home while implementing social distancing requirements and other measures to allow manufacturing and other personnel essential to production to continue work within the Company's facilities. Business travel was significantly reduced during this period. While a portion of the workforce has returned to in-office work and travel is less restricted, the Company continued to have restrictions which represent disruptions which can impact productivity including sales and marketing activities. The global supply chain has experienced significant disruptions during 2021 due to electronic component and labor shortages and other macroeconomic factors which have emerged since the onset of COVID-19, leading to increased cost of freight and purchased materials, while also delaying customer shipments. Accordingly, these conditions in addition to the overall impact on the global economy have negatively impacted results of operations and cash flows.
