Non-conforming and fraudulent components can infiltrate even the most secure supply chains, especially as their producers are able to easily find and mimic the specifications of genuine articles. Aside from likely lacking the material strength, heat resistance, and rigorous testing required for military-grade applications, these products do not have the legitimate documentation that is legally required for their installment. To avoid the risk of purchasing any unusable counterfeits, defense logistics rely on a rigid framework of NSN verification and traceability, which extends to the Commercial and Government Entity (CAGE) code. This blog will take you through what exactly a CAGE code is and how it serves as a line of defense for military and aviation parts authentication.
