China's Diphenhydramine Hydrochloride Prices Gain as Export-Grade Availability Tightens

China's Diphenhydramine Hydrochloride market strengthened in July as balanced supply-demand conditions and firm export demand supported higher prices. Consistent procurement from pharmaceutical manufacturers and stable overseas inquiries helped suppliers maintain firm offers throughout the month. Export formulators remained the primary demand driver, while domestic over-the-counter producers and hospital distribution channels continued routine purchasing, ensuring steady consumption. Although buying from some international markets was restrained, export-grade material remained relatively tight due to strong commitments from certified producers. On the supply side, production remained stable with no major plant shutdowns, while logistics conditions stayed favorable, allowing timely shipment of export cargoes. Geopolitical risks surrounding upstream feedstock availability continued to pose a potential cost risk but did not significantly disrupt market operations. Looking ahead, the market is expected to remain firm in the near term, supported by seasonal restocking and export demand, before softer procurement activity and year-end destocking are likely to moderate prices in the later months of the year.
