Track Diethylene Glycol Price Index Historical and Forecast

Executive Summary

The global Diethylene Glycol market experienced persistent pricing pressure across most regions through 2024 and 2025, driven by ample supply availability, subdued downstream demand, and fluctuating feedstock cost dynamics. While short-term supply disruptions and maintenance turnarounds occasionally supported prices, these were largely offset by weak construction activity, cautious procurement behavior, and trade frictions affecting export flows.

In North America and Europe, Diethylene Glycol prices trended downward through most of 2025, reflecting inventory overhangs, soft demand from coatings and resins, and limited cost support from Ethylene Oxide feedstocks. APAC markets displayed comparatively better resilience earlier in the period, supported by supply constraints and seasonal demand recovery, although pricing momentum moderated in the second half of the year amid weakening construction activity.

Looking ahead, the Diethylene Glycol price forecast remains cautious across all major regions. Market fundamentals indicate limited upside potential in the near term as supply remains adequate, demand recovery remains uneven, and logistics and trade uncertainties continue to influence procurement decisions.

Introduction

Diethylene Glycol is a critical intermediate chemical widely used in resins, coatings, antifreeze, solvents, and plasticizers. Its market dynamics are closely tied to the performance of construction, automotive, and industrial manufacturing sectors, as well as upstream Ethylene Oxide and crude oil trends.

Over the last several quarters, the Diethylene Glycol market has been characterized by pronounced volatility across regions. Shifts in global trade flows, feedstock cost movements, plant maintenance cycles, and changing procurement strategies have all played pivotal roles in shaping price trajectories. This article presents a comprehensive assessment of Diethylene Glycol price trends and forecasts, covering global developments, regional market performance, historical quarterly movements, and procurement outlooks.

Global Diethylene Glycol Price Overview

Globally, Diethylene Glycol prices weakened through late 2024 and most of 2025 as supply conditions improved following post-maintenance restarts and normalized production rates. Elevated inventory levels across key consuming regions restricted price recovery, while muted demand from downstream sectors further weighed on market sentiment.

Ethylene Oxide feedstock prices remained relatively stable to bearish during several quarters, limiting cost-push support for Diethylene Glycol producers. Trade disruptions, including tariffs, port congestion, and rail delays, influenced regional price differentials but did not fundamentally alter the global oversupply situation.

Regional Price Analysis

North America Diethylene Glycol Market

In North America, Diethylene Glycol prices followed a predominantly bearish trend from Q4 2024 through Q3 2025. During Q4 2024, prices edged higher toward the end of the quarter due to rising production costs linked to Ethylene Oxide and crude oil. However, weak downstream demand limited sustained price gains.

Q1 2025 opened with brief bullish sentiment amid anticipated feedstock tightness and logistical disruptions. This momentum faded quickly as feedstock prices declined and supply normalized. By March 2025, prices fell sharply, reflecting ample supply and declining demand from automotive-linked coatings.

Q2 2025 marked one of the steepest quarterly declines, with Diethylene Glycol prices in the U.S. falling significantly amid elevated inventories, subdued resin demand, and weak export inquiries. Temporary production outages provided only limited relief.

In Q3 2025, prices continued to face pressure, declining further on a quarter-over-quarter basis. Controlled production rates and inventory management prevented sharper declines, but demand remained tepid. Tariff frictions, logistics bottlenecks, and softened export activity continued to cap any upside.

APAC Diethylene Glycol Market

The APAC region displayed mixed pricing behavior over the review period. In Q4 2024, prices showed volatility as supply disruptions and geopolitical tensions initially supported the market. Weak downstream demand later moderated these gains.

During Q1 2025, APAC emerged as the strongest performing region. Maintenance turnarounds at Middle Eastern facilities and import delays tightened supply, while post-holiday restocking supported demand. Prices climbed steadily through the quarter, particularly in South Korea.

Q2 2025 sustained this bullish momentum early on, supported by supply disruptions and improving downstream demand from paints, coatings, and automotive coolant segments. However, pricing momentum softened toward the end of the quarter as imports increased and production stabilized.

By Q3 2025, APAC prices stabilized and edged slightly lower. Ample supply availability, weak construction activity, and cautious procurement behavior limited price movement. Currency fluctuations and tariff uncertainties further dampened buying interest, resulting in largely stable but subdued pricing.

Europe Diethylene Glycol Market

European Diethylene Glycol prices remained under sustained pressure throughout most of the assessment period. Q4 2024 witnessed consistent declines as oversupply, weak downstream demand, and year-end destocking activities weighed heavily on the market.

In Q1 2025, prices continued to decline despite occasional supply disruptions and logistical challenges. Any brief price support from import constraints was overshadowed by declining feedstock costs and sluggish construction and automotive demand.

Q2 2025 saw a temporary stabilization early in the quarter, supported by constrained supply and steady offtake from resins and solvents. From mid-quarter onward, inventories normalized, imports stabilized, and prices resumed their downward trajectory.

During Q3 2025, Europe recorded one of the sharpest quarter-over-quarter declines. Oversupply, muted downstream demand, and persistent logistics congestion along major inland waterways restricted pricing power. Construction weakness continued to dominate market fundamentals.

Production and Cost Structure Insights

Diethylene Glycol production costs are primarily influenced by Ethylene Oxide feedstock pricing, energy costs, and plant operating efficiency. Across most regions, Ethylene Oxide prices remained flat to weak during 2025, limiting cost escalation.

In North America and Europe, refining margins and stable energy inputs helped producers maintain controlled production costs despite falling prices. In APAC and the Middle East, operational disruptions and weather-related challenges intermittently impacted production efficiency, though overall supply remained sufficient.

Procurement Behavior and Supply Conditions

Procurement strategies across regions shifted toward short-term, need-based purchasing amid uncertain demand recovery. Buyers avoided inventory accumulation, preferring spot purchases and delayed contract commitments.

Supply conditions remained largely balanced to long, with producers maintaining disciplined output levels to manage inventories. Export-oriented regions faced softened overseas inquiries due to tariffs, currency fluctuations, and logistics constraints.

Logistics and Trade Flow Impacts

Logistical inefficiencies played a recurring role in shaping regional price movements. Port congestion in Europe, rail delays in North America, and weather-related disruptions in Asia affected delivery schedules and import parity costs.

Trade flows were further impacted by tariff uncertainties and geopolitical considerations, reducing export competitiveness and contributing to localized oversupply in several markets.

Diethylene Glycol Price Forecast and Outlook

The near-term Diethylene Glycol price forecast remains conservative across all major regions. While infrastructure spending and potential construction recovery could provide demand support later, current market fundamentals suggest limited upside.

Inventory overhangs, cautious procurement behavior, and ample production capacity are expected to keep prices range-bound. Any price recovery is likely to be gradual and dependent on sustained downstream demand improvement.
