The global Dimethyl Terephthalate (DMT) market moved higher during most of Q2 2026, with strong increases seen across several important markets. The main reason for the firm market was the rise in upstream costs and growing uncertainty in global energy supply. Geopolitical tensions between the United States and Iran created concerns around crude oil production and shipments through the Strait of Hormuz. Since DMT is closely connected to the aromatic petrochemical value chain, changes in crude oil and feedstock costs had a noticeable effect on the market.

DMT is mainly used in the production of polyester, PET, engineering plastics, and other industrial materials. Because of these applications, demand from textile, packaging, plastics, and manufacturing industries can have a direct influence on market conditions. During April and May, demand remained relatively steady, while producers and traders faced higher costs for feedstock, energy, and transportation. This combination created a supportive environment for DMT.

One of the most important cost factors during the quarter was Paraxylene (PX). Higher PX values increased the cost of producing DMT and provided a strong reason for suppliers to maintain higher offers. Energy expenses also increased, adding further pressure to manufacturing costs. At the same time, higher freight expenses affected international trade, particularly for buyers that depend on imported material.

The Dimethyl Terephthalate (DMT) Price Trend during the quarter was therefore mostly upward until the market started changing toward June. Strong demand from polyester and PET manufacturers, balanced availability, and firm export activity helped support supplier confidence. Buyers continued to purchase material to meet their regular production requirements, although purchasing strategies became more cautious as prices increased.

Toward the end of Q2, market conditions started becoming more stable. The US-Iran ceasefire reduced some of the uncertainty surrounding energy supplies, while crude oil shipments gradually returned toward more normal conditions. As energy market volatility declined, PX costs also began to soften. This reduced some of the cost pressure faced by DMT producers.

The change in upstream conditions resulted in a modest correction during June. Buyers also became more careful about inventory levels and increasingly focused on need-based procurement. Instead of purchasing large quantities in anticipation of further price increases, many downstream users preferred to wait for clearer market signals.

DMT Market in India

India recorded a significant increase during Q2 2026, with DMT values rising by 33.14% compared with the previous quarter. The increase was mainly supported by higher production costs and firm demand from domestic industries.

The rise in crude oil costs and uncertainty around international shipping contributed to stronger PX values. Since PX is an important feedstock in the DMT production chain, its higher cost translated into increased manufacturing expenses. Producers and suppliers therefore maintained firm offers during the stronger part of the quarter.

Import parity was another important factor for the Indian market. When imported material becomes more expensive, domestic suppliers generally have greater flexibility to maintain higher prices. During April and May, higher international costs and freight expenses supported import replacement values.

Demand from polyester and textile manufacturers also provided support. These industries require aromatic feedstocks and related materials as part of their production processes. Some manufacturers carried out selective restocking during the quarter, particularly when they were concerned about further cost increases or availability.

Supplier sentiment remained firm during the first part of Q2. However, buyers were not completely aggressive because higher prices increased the financial burden of maintaining inventories. Many companies therefore balanced their purchasing between immediate production needs and inventory protection.

The market began to soften toward the end of the quarter. In June 2026, DMT values in India declined by 2.37%. The main reason was weaker PX values, which reduced some of the upstream production cost support.

Lower export prices from South Korea also affected the Indian market. More competitively priced imported material became available, reducing import parity and making it harder for domestic suppliers to maintain earlier price levels. As a result, some sellers adjusted their offers to remain competitive.

Inventory levels were also more comfortable by June. Downstream polyester manufacturers increasingly followed need-based procurement instead of building large stocks. Softer domestic offers from major PTA producers added further pressure to the market. Together, these factors created a more balanced environment and limited the possibility of another sharp increase during the month.

DMT Market in Japan

Japan also experienced a strong quarterly increase. DMT values on a CIF Yokohama basis from South Korea rose by 24.04% during Q2 2026.

Higher import costs were one of the main reasons for this increase. South Korean export availability became tighter during much of the quarter, leaving Japanese buyers with fewer competitive spot cargo options. When availability becomes limited, importers often have to accept higher replacement costs to secure material.

The increase in PX values also played an important role. Rising crude oil costs and uncertainty in the global energy market pushed aromatic feedstock costs higher. This increased the cost of DMT and supported higher offers from suppliers.

Freight expenses added another layer of pressure. For imported material, the delivered cost depends not only on the supplier's quotation but also on transportation and other associated expenses. Higher freight rates therefore contributed to increased CIF values in Japan.

Tighter spot availability from South Korea further strengthened the market. Japanese buyers that needed regular cargoes had to compete for available material, particularly during periods when supply was less comfortable. This supported higher replacement costs throughout much of April and May.

However, the market began to lose some of its strength in June. Following the ceasefire between the United States and Iran, energy markets became more stable and PX values weakened. South Korean export prices also moved lower, reducing the cost of imported DMT.

In June 2026, DMT values in Japan declined by 1.76%. Comfortable product availability and cautious purchasing from downstream users contributed to the correction. Buyers had less reason to secure large volumes when lower offers were becoming available.

Market Outlook

The Q2 2026 DMT market shows how closely the material is linked to the broader petrochemical and energy markets. The strong increases during April and May were supported by higher crude oil costs, rising PX values, freight expenses, steady downstream demand, and changes in regional availability.

The situation in June was different. Improved geopolitical conditions and the gradual normalization of crude oil shipments reduced some of the earlier supply concerns. Lower PX values reduced production costs, while buyers became more selective about inventory purchases.

For manufacturers and buyers, monitoring upstream feedstocks remains important. Changes in PX costs can influence DMT production economics, while freight rates and import availability can significantly affect markets that rely on international supply.

Going forward, the market is likely to remain sensitive to energy prices, feedstock movements, regional supply, and downstream polyester demand. If PX values remain stable and product availability stays comfortable, the strong upward pressure seen earlier in Q2 could remain limited. However, any renewed disruption in crude oil supply or international shipping could quickly increase production and import costs again.

Overall, Dimethyl Terephthalate (DMT) Prices moved sharply higher during Q2 2026 before showing moderate corrections in June. India recorded a stronger quarterly increase than Japan, while both markets experienced softer conditions toward the end of the quarter as feedstock costs eased and buyers became more cautious.
