US DEG Prices Climb 12.5% on Supply Tightness and Cost Pressures

Diethylene Glycol (DEG) prices in the USA moved decisively higher through March, with the market strengthening into late-month trading as tighter global availability and elevated upstream costs fed the climb. DEG prices started the month with a bullish tone and went through mid-month in the same pattern and accelerated toward month end as sellers held firmer offers amid constrained spot-import liquidity. The tone emphasized supply-side pressure rather than a sudden surge in DEG demand; buyers remained active but cautious, enabling sellers to maintain a firmer posture as geopolitical and logistics factors amplified landed costs. Domestic DEG buying interest underpinned the advance, supporting higher offers even as import availability stayed tight. Supply-side dynamics were reinforced by sustained pullbacks in regional Middle Eastern output, tightening overall availability and supporting firmer spot values. Upstream cost pressures, linked to elevated crude and related DEG feedstock costs, continued to squeeze producer margins. Looking ahead, the near-term outlook points to DEG prices holding or firming given persistent supply constraints and elevated freight and insurance costs.

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.
