MHI — Material Handling Institute
MHI is the largest material handling and logistics trade association in the US. It's the parent organization for several industry groups (including RMI and SMA) and runs the ProMat and MODEX trade shows — the two biggest events in the warehouse industry. MHI membership signals that a company is active in the broader material handling ecosystem, not just pallet rack.
