In Q3 2022, the Dibutyl Phthalate Price of the USA ended on a mixed note. Due to unprecedented energy and utility costs, prices faced a Northward trend in the first half while slowed in the second half with adequate product availability. In July, with consistent demand for DBP in the paint and plasticizer-producing industries, the product price rose marginally for the construction and automotive sectors. However, the slower trading activity came from mid-August as market participants traded with weaker spot prices and sufficient product inventories. DBP prices showcased a bearish trend as traders sought further discounts to the overseas suppliers amid weak market fundamentals and lower bidding for the new stocks.
