In early September 2025, the global Naphthalene market demonstrated status quo, with Japan showing steadiness while the U.S. experienced mild pressure from developments in supply and demand, but no immediate or acute price volatility has been observed. Japanese producers continued regular output levels with available inventories ranging from 110–120 KT at production facilities; imports accounted for a minor percentage of total negotiating needs (from 2018 to 2024, imports accounted for a minor percentage of total Japanese Naphthalene supply). Demand continued to be stable in the construction-related markets for dyes, resins, and coatings, as Japanese Naphthalene exports to Southeast Asia provided minor or light support. In the U.S. markets, European imports maintained total supply levels at charted available levels of 90 KT; however, refined CFR Houston prices ticked down 1.11% from the prior report period ending wave a 12-week price low momentum. Concern from the construction industry's seasonal slowdown and weakness in the broader industrial sector contributed bearish sentiment, which would signal defensiveness in near-term demand expected across the OEI markets even while imported and domestic supply chains remain strong.
