Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies — The accompanying unaudited condensed consolidated financial statements of American Vanguard Corporation and Subsidiaries (“AVD” or “the Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, all adjustments (consisting of consolidating adjustments, eliminations and normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. The financial statements and related notes do not include all information and footnotes required by US GAAP for annual reports. This quarterly report should be read in conjunction with the consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2020. The Company is closely monitoring the impact of the novel coronavirus (COVID-19) pandemic on all aspects of its business, including how the pandemic will impact its customers, business partners, and employees. The Company is considered an essential business by most governments in the jurisdictions and territories in which the Company operates and, as a result, did not incur significant disruptions from the COVID-19 pandemic during the three-months ended March 31, 2021 and 2020. During the three-month period ended March 31, 2021, the Company has experienced strong demand for its products, more stability in foreign exchange rates and, in some jurisdictions in which it operates, return to more normal business activities including more face-to-face meetings with customers and suppliers etc., albeit at a much-reduced level as compared to pre-pandemic times. The Company established a pandemic working group at the start of the COVID-19 pandemic. That group meets bi-weekly and is presently monitoring the safety of its employees, especially in Brazil and India, as those countries are experiencing a surge in new virus variants. During the same period of the prior year our business operated comparatively normally, however, was impacted by adverse movements in some key currency exchange rates as the pandemic news spread across the globe. Looking forward, the Company is unable to predict the impact that the pandemic may have on its future financial condition, results of operations and cash flows due to numerous uncertainties. The extent to which the COVID-19 pandemic impacts the Company’s operations and those of its customers in the near term will depend on future developments, which are highly uncertain and, beyond extrapolating our experience since the start of the pandemic, cannot be predicted with confidence. The Company continues to monitor its business for adverse impacts of the pandemic, including volatility in the foreign exchange markets, demand, supply-chain disruptions in certain markets, and increased costs of employee safety, among others.
