Diethylenetriamine (DETA) Price Trend Q3 2025
In Q3 2025, the global Diethylenetriamine (DETA) market showed uneven performance across regions, with price fluctuations ranging from 6-18%. Western markets, particularly Western Europe and Western Asia, experienced sharp declines due to weak demand from polyamide and resin sectors, high inventories, and competitive import pressures.
European and Middle Eastern producers, including those in the Arabian Peninsula, faced moderate price erosion amid stable feedstock availability and subdued global orders. In the Asia-Pacific region, East Asia recorded the steepest drop on abundant domestic supply and sluggish export demand, while South Asia saw a significant decline due to soft procurement from textile and paper industries.
Southeast Asian import markets such as Southeast Asia reflected milder contractions, supported by steady supply from the Arabian Peninsula and balanced freight conditions.
In general, the market remained bearish, underpinned by oversupply concerns, cautious buying behaviour, and weak downstream consumption. Regional supply chain dynamics and divergent demand trends continued to drive pricing during the quarter.
