Ineos to regain full ownership of Runcorn MCP
Ineos to regain full ownership of Runcorn MCP
London, 21 August (Argus) — Ineos Inovyn has agreed to acquire the remaining 50pc stake in Runcorn MCP, including the EDC assets of Vynova Runcorn, which entered administration in late 2025. The deal will return the site to full Ineos ownership, subject to regulatory approval. Runcorn MCP accounts for 89pc of UK chlorine capacity and has chlorine production capacity of 430,000 t/yr, underlining its importance to the country's chlor-alkali and downstream chemicals industries. The site is currently operated as a 50:50 joint venture between Ineos Inovyn and PVC producer Vynova. EDC is the largest outlet for chlorine production at Runcorn. Volumes were previously exported mainly to Wilhelmshaven in Germany and Martorell in Spain for PVC production.

Higher PVC, soda prices boost Unipar Q2 results
Higher PVC, soda prices boost Unipar Q2 results
Sao Paulo, 7 August (Argus) — Brazilian chlor-alkali and PVC producer Unipar Carbocloro posted stronger second-quarter 2026 results supported by the ramp-up of its Cubatão plant, higher international soda and PVC prices, and increased sales volumes, it said during its earnings call. Sales volumes increased quarter on quarter, with soda up 9pc, PVC up 6pc and chlorinated products up 4pc. Unipar highlighted chlorinated products as a strategic segment because it is less exposed to petrochemical cycles than PVC. The improvement in Brazil was driven by Cubatão reaching full operating capacity in April, while operations in Argentina remained stable, chief financial officer Alexandre Jerussalmy said. Higher international soda and PVC prices driven by the ongoing conflict between US and Iran supported revenue and helped to offset higher ethylene and natural gas costs, although an appreciation of the Brazilian real against the US dollar had a negative effect on results. The company also reported progress in its chlorine liquefaction project in Camaçari, Bahia state, aimed at increasing purification and expanding higher-value product sales. In Santo André, Unipar is advancing an expansion project that will add 28,000 t/yr of PVC capacity through the installation of an additional electrolyzer.

Middle East EDC output remains low post-Iran ceasefire
Middle East EDC output remains low post-Iran ceasefire
Singapore, 23 June (Argus) — Middle East ethylene dichloride (EDC) production remains constrained heading into the third quarter despite the US-Iran ceasefire and the reopening of the strait of Hormuz, as producers face persistent vessel congestion, high inventories, and weak vinyl chloride monomer (VCM) and polyvinyl chloride (PVC) spot prices, market participants said. Before the US-Iran war, most Middle Eastern EDC suppliers were already running at reduced rates because of weakening chlorine netbacks into EDC and lower demand from the PVC sector. Most producers were either catering for EDC contractual supplies, or for their respective PVC production, rather than supplying the EDC spot market. Asian chlorine netbacks into EDC were assessed at -$86.30/t and -$76.51/t in January and February 2026, respectively, according to Argus data. Following the onset of the war, the closure of the strait of Hormuz made it uneconomical for domestic EDC producers to keep running since vessels could not leave the strait and domestic inventories piled up. QatarEnergy declared force majeure on deliveries of several chemical products on 9 March, while two Saudi EDC producers reduced rates heavily as they were unable to reach certain customers in south Asia. Since then, Argus suspension PVC (s-PVC) import prices into India, Vietnam and the Gulf Cooperation Council (GCC) have fallen by 35pc, 39pc, and 21pc, respectively, as of 19 June from their peaks on 20 March. May VCM monthly spot prices also saw declines of 20pc in northeast Asia and 29pc in southeast Asia, with recent indications pointing to further drops in June. This would bring both current PVC and VCM prices close to historical lows since before the US-Iran war, leading Middle Eastern EDC producers to reconsider increasing operating rates even as feedstock costs declined and the strait reopens. Most EDC producers are currently focusing on destocking efforts before ramping up production rates, but many expect that this will take time and likely determined by how quickly vessel congestion along the strait eases. Concerns from India remain surprisingly low Middle Eastern EDC supply primarily flows into India, as many PVC producers there rely on imported EDC feedstocks for their production. Total EDC imports into India in 2025 were 690,926t, with the Middle East contributing 51pc of the total, data from Global Trade Tracker (GTT) show. As a precautionary measure over the war-related uncertainty and reliability of feedstock supplies, the Indian government introduced duty waivers across different imports — including PVC — and the prioritisation of feedstock LPG output across certain sectors. But despite a potential delay in the resumption of EDC supply from the Middle East, along with other key feedstocks, Indian PVC producers are not so concerned over EDC supply security as some secured enough imports to meet more than three months of domestic demand. While current GTT data for 2026 is slightly delayed, EDC imports from western Europe into India between January and April 2026 were 57,776t — more than half of the full-year total for 2025. This could lead to a potential reintroduction of PVC import duties into India beyond 30 June to control overseas supplies into the country, with senior government officials recently investigation a potential extension to duty waivers before the ceasefire . But a decision has yet to be made on this, with market participants expecting further announcements from the government in the coming days.

Acid prices offsetting higher sulfur costs: Chemtrade
Acid prices offsetting higher sulfur costs: Chemtrade
Houston, 12 May (Argus) — Chemical producer Chemtrade expects sales prices for sulfuric acid and other sulfur-based products to offset feedstock costs, despite record-high sulfur prices, the Canada-based company said. The second-quarter Tampa sulfur settlement reached a new record at $655/long tonne delivered. Chemtrade said that increased selling prices of merchant acid helped to offset elevated raw materials costs. Meanwhile, both selling prices and demand for regen acid were supported by increased demand from refineries. US Gulf coast refinery utilization has averaged over 95pc since the week ending 6 March, according to the US Energy Information Administration. The closure of the strait of Hormuz in early March cut off supplies of jet fuel and distillate from producers in the Middle East, supporting increased throughputs and higher exports from the US. Higher sulfur costs have not reduced operations at the company's ultrapure acid facilities. It expects ramp-up of its ultrapure acid projects in Cairo, Ohio, and Tulsa, Oklahoma, to continue throughout 2026, with Chemtrade working with four semiconductor manufacturers for commercial agreements and quality certification. But Chemtrade reiterated the likelihood of some customers switching to hydrochloric acid from sulfuric acid for some applications such as mining and steelmaking, because of increased sulfur and sulfuric acid prices. The company also produces hydrochloric acid as part of its chlor-alkali business. Chemtrade reported a $25.4mn profit in the first quarter, compared with a $49.1mn profit the same period a year earlier.
