Minimum stock and reorder point are related inventory controls, but they are not identical. Minimum stock is the lower buffer a facility wants to protect. The reorder point is the level at which a new order should be placed so replenishment arrives before stock falls too low.
Minimum stock is the protected floor
It represents the quantity the facility does not normally want to fall below because doing so increases operational risk.
Reorder point is the action trigger
The reorder point should normally be set above minimum stock so there is enough inventory to cover expected use during supplier lead time.
Lead time strongly affects the reorder point
Longer or less predictable delivery times generally require a larger buffer between the reorder point and the minimum level.
Consumption rate also matters
Fast-moving chemicals need earlier reorder triggers than low-use products, even when the pack size is similar.
Review both when conditions change
Supplier reliability, consumption, seasonality, facility occupancy and product specifications can all change the appropriate settings.
Practical takeaway
Minimum stock answers “how low can we safely go?” Reorder point answers “when should we order?”
