COVID-19 pandemic, as an unprecedented phenomenon in the modern world, has considerably damaged the international trade, business and supply chain. Previous researches show that although, some restrictions and quarantine are helpful for decreasing the negative impacts of the pandemic, but these have cause trade and economic crisis. In this environment, the World Customs Organization (WCO) plays a pioneering role in combating against the damaging effects of the COVID-19 pandemic. It has invited all its members to share their best practices and policies for preventing the spread of the pandemic. The WCO categorizes them into 4 distinctive groups: facilitating the cross-border movement of relief and essential supplies, supporting the economy and sustaining supply chain continuity, protecting staff and society. This research shows that the mentioned practices and policies can significantly reduce the trade and economic recession of the pandemic and implementation of these practices in critical times can be useful to promote the economy and trade and can help the researchers, policy-makers and stakeholders in combating the negative effects of the pandemic.
