US Vitamin D Market Extends Decline as Early-June Weakness Deepens

Terry Pratchett 10-Jun-2026

US Vitamin D prices continued to show signs of softness in early June, extending the downward momentum that shaped trading conditions through May. Market participants reported that overall sentiment remained cautious, with Vitamin D demand steady but unspectacular and buyers reluctant to take on additional volumes amid stable production and minimal cost pressure. Despite a brief mid May uptick, the broader trend pointed to persistent weakness. Throughout May, Vitamin D activity was largely rangebound, supported by balanced supply–demand fundamentals and smooth logistics. However, thin liquidity in this specialty feedstock meant that even modest shifts in order flow had an outsized impact on market direction. This dynamic became more pronounced at the start of June, when a clear decline signaled a shift in momentum and reinforced the market’s vulnerability to sentiment driven moves. Analysts noted that the prolonged easing of moving average indicators underscores the sustained bearish tone. While no major supply disruptions or cost shocks are expected, the near term outlook for Vitamin D remains cautious. Renewed buying or inventory adjustments could stabilize conditions, but traders are closely watching weekly assessments to determine whether early June weakness marks the start of a deeper trend.

Selenis has effectively manufactured recycled PET chips using terephthalic acid sourced from Circ®, a textile-to-textile recycler based in Virginia. The chip production took place through a series of batches at Selenis' pilot plant in San-Giorgio, Italy. By utilizing inputs recovered from polycotton textile waste, Selenis has created high-quality PET chip, which has been further processed into DTY yarn. This yarn will play a crucial role in product development as Circ prepares for additional capsule launches. Selenis is leveraging the success of this initial collaboration phase and is committed to advancing towards an offtake partnership to support Circ's inaugural industrial facility. Eduardo Santos, Head of Corporate Strategy at Selenis, remarked that the monomer synthesis showed a performance comparable to virgin terephthalic acid. He expressed optimism about the consistent quality of Circ's monomer output and anticipated future commercial success. Santos pointed out that the Circ partnership complements Selenis's existing mission and goals for a more sustainable textile industry. He further stated their anticipation of expanding upon this collaboration and providing support for Circ's forthcoming commercial production trials.
