Safety stock acts as a silent buffer in inventory management: unlike the reorder point, which triggers a purchase order, safety stock is held in reserve specifically to absorb supplier lead time variability, demand fluctuations, and forecast errors without disrupting regular operations. Supply chain planners size it according to the volatility of both lead times and demand – the more unpredictable the supply chain, the larger the required buffer. Insufficient safety stock leads to stockouts and production halts; excess ties up working capital and warehouse space. In cross-border trade, customs clearance lead times add an extra variable that must be factored into the calculation.
