Weekly Chemical Market Tracker: Update for October 19-26, 2026

26 Oct 2026 • by Natalie Aster

Chemical markets the last week showed a split between stronger pricing in polyethylene and unresolved weakness in some end-use volumes. At the same time, potential EU trade safeguards and new research on microplastics brought supply security and material safety back into focus.

Dow’s third-quarter results show polyethylene price strength

Dow reported third-quarter net sales of USD 11.3 billion, up 13% year over year, on 22 October. Local prices rose 14%, led by a 17% increase in Packaging & Specialty Plastics, as polyethylene prices rose across all regions. Yet total sales volume fell 1%, with Asia-Pacific down 12%. In the plastics segment, sales increased 18% to USD 5.78 billion, while volume rose only 1%.

The figures suggest that higher selling prices, rather than broad-based volume growth, drove much of the improvement. For market coverage, this is a useful distinction: revenue growth alone does not confirm a demand recovery. Track PE prices, regional volumes and feedstock costs separately.

EU weighs safeguards on plastics imports

On 23 October, EU Trade Commissioner Maroš Šefčovič said an investigation into safeguards for plastics imports appeared to be the next measure under consideration. The EU is examining whether conditions are met to investigate PET imports, while ministers also cited chemicals as a sector for further trade discussions. The proposals remain under assessment; no new plastics restrictions were announced as enacted. Reuters reported that the EU’s goods trade deficit with China exceeded EUR 370 billion in 2025 and could surpass EUR 400 billion in 2026. 

Any PET investigation could influence packaging-resin sourcing and trade flows, but the immediate market impact depends on whether an investigation is launched and what measures follow. Articles should describe this as a potential safeguard, not a confirmed quota or tariff.

Microplastics research adds a material-safety angle

A Columbia University study reported this month suggests that microplastics can generate reactive oxygen species when they interact with water. Experiments observed the effect with polystyrene, polyethylene and PET; in one test, a dye degraded over 10 days in the presence of polystyrene particles and water. The researchers also detected reactive species in blood serum and cell cultures. These results point to a possible chemical mechanism, but they do not establish the level of risk from everyday exposure or prove clinical effects in people. 

For plastics and packaging markets, the research may add momentum to scrutiny of polymer safety and particle exposure. It is an emerging scientific finding, not a regulatory decision.

Carbon-recycling demonstration advances in Japan

On 22 October, Mitsubishi Chemical, JFE Steel and Mitsubishi Gas Chemical announced a demonstration project to develop a carbon-recycling supply chain at Japan’s Mizushima industrial complex. The project links industrial emissions and chemical production, making it relevant to efforts to reuse carbon as a feedstock. The companies’ announcement establishes a demonstration initiative, not yet commercial-scale capacity. 

What chemical market analysts should watch

This week’s developments underline three useful signals: PE price gains are outpacing volume growth, EU plastics trade measures remain under consideration, and carbon recycling is progressing through industrial demonstrations. Together, they offer timely angles for market research on polymer pricing, PET trade and low-carbon chemical feedstocks – while keeping confirmed results distinct from proposals and early-stage research.
