Supply Chain Investigation
Supply chain investigation is the process of identifying how unauthorized sellers are sourcing brand products and reaching marketplaces. It is the foundational step of effective grey market and unauthorized seller enforcement — because without knowing the source of supply, enforcement actions treat symptoms rather than causes.
Supply chain investigation typically involves test buys, seller identity research, cross-referencing listing data with distribution records, and coordinating with authorized accounts to trace product flow. The goal is to identify the specific distributor, wholesaler, or retail account responsible for the leakage — and terminate or restructure that relationship.
