How does China's cephalexin monohydrate supply chain respond to upstream cost changes?
China's cephalexin monohydrate supply chain is vertically integrated, with major producers controlling both penicillin G potassium salt and 7-ADCA steps. This integration helps buffer against raw material price swings, but not entirely. Recent fluctuations in corn and glucose prices, key inputs for penicillin fermentation, have been modest. More notably, energy costs and logistics disruptions have added to production expenses. Producers have shown discipline, adjusting operating rates to match demand rather than flooding the market. Inventory levels across the industry are moderate, and no major capacity expansion is underway. This suggests that any sustained rise in upstream costs could be passed through to cephalexin prices, though intense competition among domestic players may limit the magnitude of such increases.
