In August 2025, China’s Vitamin D3 market experienced a pronounced downturn driven by subdued domestic and international demand alongside elevated inventory levels. Stable production and uninterrupted logistics sustained supply, but cautious buyer sentiment and preference for spot purchases suppressed transaction volumes. Export activity weakened due to global trade uncertainty and extended U.S.-China tariff truce, further dampening overseas orders. Suppliers accelerated stock clearance amid regional disruptions, offering discounts to stimulate sales. With muted demand and persistent oversupply, bearish market conditions prevailed, exerting downward pressure on prices expected to continue in the coming months.
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.
