The export market prices of Diphenhydramine Hydrochloride in China have increased in December 2025. The increase in the market value of Diphenhydramine Hydrochloride has followed a significant decline which was observed in previous month, November of 2025. The shift in the Diphenhydramine Hydrochloride prices was observed by the domestic and international buyers as the market has shifted from cautious procurement to more active purchases. The decline in November was the result of limited purchases of the buyers which resulted in the lean inventory position across several of the downstream segments. The buyers have reassessed their stock levels in December for upcoming production schedule of early 2026. The shift in buying sentiment with the strategic response from suppliers have created a renewed increase in the market. The improvement in demand was not abrupt and has reflected calculated inventory management to align it with the downstream production. ChemAnalyst anticipates that the prices of Diphenhydramine Hydrochloride will likely decrease in January of 2026.
