Backup-Vendor Strategies for Single-Source Consumables

When a single supplier controls a critical item, supply chain resilience requires more planning than most facilities realize—here is how to build it before a shortage, not during one.

Why this matters

Consider a hospital laboratory running a high-volume molecular diagnostics platform. The reagent cartridges are proprietary—cleared by the FDA as an accessory to a specific analyzer under a 510(k)—and the manufacturer is the only entity with clearance for that device configuration. A six-week production stoppage, whether triggered by a natural disaster, a regulatory action, or a raw-material shortage, can suspend testing for hundreds of patients.

The vulnerabilities are structural, not exceptional. The supply disruptions of 2020 and 2021 revealed that large shares of U.
