The prices of Vitamin B1 followed an upward trajectory throughout March 2025, consistent with the trend seen in the previous month. The price rise for Vitamin B1 was mostly caused by customers' strategic realignments of inventory, changes in trade policy, and a tightening of the supply chain.

On the demand side, the pharmaceutical segment has sustained fairly consistent volume for Vitamin B1 in the medical and supplement sectors. On the other hand, the need from the animal nutrition sector, a significant customer for Vitamin B1, remains strong as livestock and aquaculture producers build inventory ahead of the peak feeding period. This tight demand and strong supply connection has produced optimal circumstances for sustained price growth.

China’s manufacturing sector expanded at its fastest rate in a year in March. The increase in new orders contributed to production levels increases, confirming the growth in Vitamin B1 prices. Increased support from recent fiscals has helped the economy, and a sense of urgency has emerged from foreign buyers of a possible tighter U.S. trade environment. This mix of domestic stimulus and external demand has kept optimism in the manufacturing sector actively high.

Concerns on U.S.–China trade relationships contributed significantly to the Vitamin B1 price spike. Beginning March 4, the United States government further imposed import duties on Chinese items. In response to the increased general trade uncertainty, buyers all along North America sped up their March acquisitions to prevent possible transit disruptions and higher future costs. This caused a significant increase in demand in the month, further straining a market already under stress and affecting the pricing of Vitamin B1.

Adding a fresh level of disturbance, major Chinese ports—including Ningbo, Shanghai, and Qingdao—suffered severe congestion. Prolonged waiting times, stemming from the pairing of adverse weather plus heavy vessel volumes, resulted in a large amount of cargo piling up at anchorages in North Asia. According to logistics experts, even reservations made in advance did not avoid bottlenecks, which increased pressure on the supply of vitamin B1 in important global markets.

Meanwhile, Europe is turned into one of its own congestion hotspots. Labor stoppages and industrial action caused operations at ports across major European locations such as Rotterdam, Le Havre and several Spanish ports to come to a halt, with Hamburg now joining the list as early as March. The constraints in the transportation network have caused disruptions in the delivery schedules for Vitamin B1, have increased lead times and freight costs. Although eurozone inflation slowed down to 2.2% in March, giving more confidence to consumers, the logistics bottlenecks compelled many European importers to build up their safety stock ahead of further delays and cost pressures.

According to the ChemAnalyst, Vitamin B1 prices are anticipated to surge globally in the coming months driven by a supply shortfall and sustained demand from downstream nutraceutical manufacturers. With trade-related cost pressures beginning to show and suppliers are refining their export policies, global supply is expected to be constrained. On the other hand, buyers will probably be gradually but steadily replenishing stock, thus supporting Vitamin B1 demand.
