The current global situation due to the COVID-19 illness has seriously impacted the capacity of the supply chains to accomplish timely and in a reliable way the availability of essential biosafety products. Production and trading companies of biosafety products have experienced an unpredicted change in the product demand. This is due to the protocol international regulations from health organizations regarding the use of biosafety products and their use to mitigate the virus propagation. For the companies involved in these supply chains, their priority is to keep appropriate service levels in the current scenario, guaranteeing high availability at each echelon to help life´s preservation. It requires to maintain articulation and flexibilization of the processes in the supply chain, reflected in the decision making. In this world with high volatility, uncertainty, complexity, and ambiguity (VUCA), where the traditional practices are no longer effective, rationality, people´s training, and the experience for the decision-making are essential.Nevertheless, despite the relevance of the problem, studies about business strategies of multiple product inventories and their impact on the service level and volatile demand during a pandemic is limited. This paper focuses on the experience of a Colombian Company of biosafety products. The key contribution of this proposal leads to some important insights for biosafety companies managing many highly demanded products, volatile behaviour, and very important items for containing the spread of a virus in a complex and dynamic market influenced by a global disruption of supply chains, in this case the COVID-19 pandemic.
