During this period, following the holiday, the center of domestic DBP market prices rose continuously. This was primarily driven by sustained increases in raw material prices for n-butanol and phthalic anhydride produced via the naphthalene process, providing strong cost support. Additionally, the overall operating load of domestic DBP plants remained moderate-to-low, limiting market supply. Under these dual supports, low-priced offers in the domestic DBP market gradually disappeared, and transaction prices moved toward higher levels. Downstream demand remained at rigid necessity levels, with buyers adopting a cautious approach, mainly purchasing on dips. Market inquiries and transactions performed well.
