US Mixed Xylene Prices Fall 6.45% in late May 2026, as supply improves

Ian Fleming 03-Jun-2026

The US mixed xylene market entered June 2026 with a firm undertone despite a late-May correction, as underlying supply and demand fundamentals continued supporting elevated pricing levels. Mixed xylene demand from gasoline blending and paraxylene production remained healthy throughout May, while domestic supply constraints and strong aromatics-chain economics sustained seller confidence. Although spot offers softened toward the month-end following improved logistics and short-term supply relief, the broader market remained considerably stronger than recent historical norms. Rising crude oil values, constrained reformate availability, and steady procurement from refiners and aromatics consumers continued to underpin market sentiment. Market participants remain focused on summer gasoline blending demand, refinery operating rates, and crude price movements as key indicators for the coming weeks. While periodic corrections remain possible, mixed xylene fundamentals continue to favor a constructive outlook, with supply limitations and resilient downstream demand expected to support pricing through the near term.

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.
