China FOB prices for Vitamin B1 (Thiamine) are expected to remain stable during the first half of June as producers maintain firm quotations despite subdued inquiry activity. Limited fresh buying interest from overseas markets has created a balanced market environment, preventing significant price movements. However, sentiment remains cautious, with analysts anticipating mild downward pressure in the second half of June as earlier procurement activity reduces immediate purchasing requirements and supply availability improves. The market received strong support during May from robust demand across the animal feed, pharmaceutical, and nutraceutical sectors. Feed manufacturers advanced purchases for upcoming premix programs, while pharmaceutical buyers, particularly in India, increased procurement ahead of seasonal logistics challenges. Additional demand from dietary supplement manufacturers in key international markets further supported export activity. Supply conditions also influenced market dynamics. Producers allocated a larger share of output to export commitments, reducing spot availability and lowering port inventories. Looking ahead, restocking demand, pharmaceutical consumption, and feed-sector requirements are expected to support market recovery, although freight costs, geopolitical developments, and regulatory changes will remain key factors shaping future market trends.
China FOB offers for Vitamin B1 (Thiamine) are expected to remain stable in the first half of June as producers maintain firm quotations despite subdued buying interest. Market participants reported limited fresh inquiries from overseas buyers, resulting in a balanced trading environment where Vitamin B1 sellers have largely resisted price reductions. Although demand has softened compared with the active purchasing seen in May, the current supply-demand balance has helped keep Vitamin B1 prices broadly unchanged during the opening weeks of June. However, market sentiment remains cautious, and a modest correction is anticipated in the second half of the month as earlier procurement activity reduces immediate purchasing requirements for Vitamin B1.
China FOB offers for Vitamin B1 rose by 1.91% in May 2026 on a month-on-month basis, supported by stronger export demand and compliance-related production costs. The increase reflected tighter prompt availability and improved buying activity across major international markets. While prices have remained stable so far in June, market participants are closely monitoring inquiry levels, inventory positions, and export orders to assess the direction of Vitamin B1 pricing during the remainder of the month.
The stronger performance of Vitamin B1 in May was driven by healthy demand from several end-use sectors. The animal feed industry remained a key source of support as feed compounders advanced purchases for third-quarter premix programs. Chinese hog feed manufacturers also maintained steady inclusion rates, preventing any significant slowdown in consumption. Pharmaceutical demand for Vitamin B1 was equally robust, with Indian buyers securing additional cargoes ahead of seasonal monsoon-related logistics disruptions. Nutraceutical and dietary supplement manufacturers in the United States, Brazil, and India further contributed to the export demand for Vitamin B1 through increased inquiries and procurement activity.
Supply-side conditions also played a significant role in supporting Vitamin B1 prices during May. Several producers prioritized higher-margin thiamine hydrochloride production and allocated a substantial share of output to confirmed export shipments. This reduced spot availability of Vitamin B1 and pushed Shanghai port inventories to their lowest levels since February. Additional support came from stricter environmental compliance requirements, which increased treatment costs for manufacturers. A brief power curtailment in Hebei further tightened near-term availability and reinforced the upward price trend.
Despite these supportive factors, the outlook for Vitamin B1 in the second half of June points to mild downward pressure. Earlier purchasing activity has reduced immediate buying needs, while improved product availability is expected to ease supply tightness. Although some Chinese producers have raised quotations, actual Vitamin B1 transaction levels remain stable due to weak inquiry volumes. Looking ahead, analysts expect the Vitamin B1 market to recover in the coming months as pharmaceutical and nutraceutical demand strengthens and feed-sector restocking resumes. Nevertheless, freight costs, geopolitical developments, and regulatory changes will remain important factors influencing the future direction of the Vitamin B1 market.
