Chemical markets prepare for Canadian rail strike

Spanish Market: Chemicals, Petrochemicals
02/08/24

Chemical industries in North America are bracing for a potential rail strike in Canada, but some markets expect greater impacts than others.

Participants across a variety of industries have expressed greater certainty that a rail strike is now likely after momentum for a strike several months prior had fizzled out. The Canadian Industrial Relations Board (CIRB) is making considerations that are due to be posted no later than 9 August, with some market participants expecting a strike to be called somewhere within 72 hours thereafter. The CIRB is evaluating what, if any, materials would be constituted as essential to move even during a strike.

Chlorine

The chlor-alkali market has raised concerns about a potential strike, with some suppliers of chlorine and hydrochloric acid (HCl) in Canada pushing for a strike to be delayed or for its products to be considered essential. Chlorine and HCl are both used in water treatment, and suppliers have said a prolonged stoppage in rail service without proper considerations for such products could endanger some municipal water supplies.

In the lead up to a potential strike, Canadian chlor-alkali producers and their US counterparts positioned close to the Canadian border have been trying to build up buyers' on-site inventories as a precaution. Producers have warned, however, that such contingency plans only work if the strike is not prolonged, as stoppages lasting longer than a few weeks could be problematic. Wildfires across central Canada have been complicating the efforts to ensure downstream inventories, as the fires have encroached on crucial rail lines and delayed or rerouted supply.

Polymers

In the polymers markets, polyethylene (PE) and polypropylene (PP) producers in Canada, including Nova Chemicals and Heartland Polymers, made advanced preparations for a rail strike back in May. Both companies had moved some inventories in advance to storage warehouses in the US to limit supply disruptions to US customers.

In addition to storage on the US side, sources said the Canadian producers were also making plans for storage on the Canadian side so they could continue to operate, even if railcars were no longer moving. As long as a strike would not last more than a few weeks, most market participants said they believed there would be minimal disruption to the overall market.

An extended strike would likely result in some shipping delays, but producers on the US side could raise operating rates and potentially help to fill in any supply gaps.

Polyvinyl chloride (PVC) customers in Canada had stocked up on supply back in May as well, with minimal concerns of disruption so long as any stoppage did not drag on. Some pipe producers with plants in Canada have also said the need to stock up on inventory has been lessened due to Canada's weaker economy and construction sector.

Polystyrene (PS) distributors have been positioning resin supply in the northeast and Midwest to quickly move across the border if need be, but warehouses in Canada were reportedly oversupplied on PS and turning away extra railcars.

Recycled polymers market participants indicated that with current low demand and low volume trades, the rail strike will likely lead to more truck usage rather than completely halting trades altogether.

Chemicals

The butadiene (BD) market reported that a Canadian rail strike would impact cross-border trade flows of feedstock crude C4 and BD into the US.

A BD producer in Sarnia, Ontario, primarily delivers BD to US customers in the Midwest — a fact that has prompted some concern from US customers about the impacts of a potential rail strike. Some BD buyers have worried thatprolonged disruptions to Canadian volumes could add tightness to the domestic US market, especially in cases where consumers are unable to source volumes from the US Gulf coast.

Concerns from the ethylene and aromatics markets were muted, and the isocyanate and polyurethane (PU) markets expressed little concern as most buyers were able to bring supply in by truck. Moreover, the vast majority of supply for the isocyanate chain comes from production in the US Gulf, meaning the majority of any transit would be conducted on lines not impacted by the strike. Methanol market participants also did not express significant concerns.

Mass-balance consultation questions remain: BlueAlp

London, 11 July (Argus) — Some uncertainty remains over the correct interpretation of the draft of rules governing the inclusion of chemically-recycled plastics towards EU recycled content targets, BlueAlp chief executive Valentijn De Neve told Argus , but he said that an initial reading threw up some encouraging signs and some concerns. The European Commission opened a public consultation on a draft update of the implementing decision for the Single-Use Plastic Directive (SUPD) — which would provide details on how the 25pc recycled content requirement for PET beverage bottles can be met — on 8 July. It includes proposed rules around the use of mass-balance accounting to allocate chemically-recycled content. It is seen by many in the industry as a likely precedent for the rules that will apply to the EU's Packaging and Packaging Waste Regulation (PPWR), which will become the primary legislation governing recycled content targets for plastic packaging from 2030. De Neve said that he is still looking to understand the full connotations of the draft document put forward by the commission. At first reading he is encouraged that it appears to open up the possibility of plastic-derived pyrolysis oil (PPO) being processed in existing assets — refineries — as well as on-purpose upgrading facilities. This is "key in getting [the PPO market] to a realistic and larger market, and to fulfil the sustainability criteria that we've jointly set", he said. De Neve expressed some possible reservations on whether recognition of what share of input "really translates into circular plastics versus what becomes fuel" when the supply chain includes a refinery step has been "sufficiently captured" in the draft. But he said that he would discuss this within the Chemical Recycling Europe industry association, which would co-ordinate a response to the consultation. De Neve also said that the proposed extension of the definition of post-consumer plastic waste to include waste from products placed in non-EU markets — which would enable recyclates based on non-EU waste to count towards the recycled content targets — risks attracting import pressure from producers in lower-cost regions without sufficient additional controls. "We need to make sure… whether you're operating inside or outside the EU, that the same rules apply and it's a level playing field", he said. PPWR contains a so-called "mirror clause" stating that recyclers from outside the EU should be held to the same environmental standards as domestic operators. But no such clause exists in the SUPD, or elsewhere in the draft implementing decision released under consultation.

Italy's Agroenergy plans 'zero-emission' biorefinery

Italy's Agroenergy plans 'zero-emission' biorefinery

London, 10 July (Argus) — Nine organisations including Italian Agrolio-Agroenergy biogas plant and research institutions have partnered to design a fully integrated "zero- emission" biorefinery using olive mill waste as feedstock. Agrolio-Agroenergy, also known as BTS biogas, operates and builds biogas and biomethane plants primarily in Italy, but also in France, the UK, Belgium and the US. The biorefining innovation project plans to create a biorefinery capable of producing "zero-emission" bioproducts including bioplastics, bioenergy, biofertilisers, and biopesticides, according to the firm's press release. It remains unclear where the new biorefinery site will be located and what its capacities will be. Agrolio has yet to reply to a request for comments. The EU is the largest producer of olive oil and the process currently generates large volumes of waste. The improper disposal of olive mill waste can lead to soil degradation and water pollution. The biorefinery will use green chemistry and microbial processes instead of conventional methods to convert the olive mill feedstock into useable bioproducts. The project will run for four years and is receiving €4mn ($4.68mn) in funding from Horizon Europe, the EU's funding programme for research.

PVC producer Vynova to close Beek site

London, 8 July (Argus) — European chlor-vinyls producer Vynova said it intends to close its 225,000 t/yr PVC producing site in Beek, the Netherlands, by November 2025. The company said pressures on the site included "global overcapacity, persistently weak demand and increased competition from regions with lower production costs and less stringent regulations". Vynova said it did not expect these conditions to improve in the short term. The company also operates a 275,000 t/yr capacity PVC producing site in Mazingarbe, France, and a 340,000 t/yr site in Wilhelmshaven, Germany. Two PVC producing sites in Europe have already closed this year — a 135,000 t/yr capacity plant in Spolana, Czech Republic, and a smaller site operated by Fortischem in Slovakia.

EU proposes support package for chemicals sector

EU proposes support package for chemicals sector

Brussels, 8 July (Argus) — The European Commission today proposed a package of measures to support the EU chemicals sector, aiming to address high energy costs, global competition and weak demand. The plan includes extending emissions trading system (ETS) compensation to more producers and simplifying fertilizer registration rules. The commission said the simplification measures could save the sector €363mn/yr. The proposals are part of a broader action plan to boost competitiveness and secure supply chains. A new Critical Chemicals Alliance will identify key production sites in need of policy support, including on trade issues such as supply chain dependencies and market distortions. The commission also pledged to apply trade defence measures more quickly and expand chemical import monitoring under an existing surveillance task force. While the commission stopped short of proposing a Critical Chemicals Act — which would legally define specific chemicals for support — it named steam crackers, ammonia, chlorine and methanol as "essential" to the EU economy. The alliance will aim to align investment and co-ordinate support, including through the bloc's Important Projects of Common European Interest (IPCEI) programme. The commission also decided on new rules legally defining low-carbon hydrogen today and said it plans to allow more state aid for electricity-intensive chemical producers by the end of the year. It also encouraged the use of carbon capture, biomass, waste and renewables. EU industry commissioner Stephane Sejourne said the action plan uses "all levers" to put the chemicals sector back on a growth track, with measures to retain steam crackers and other key chemical assets in Europe. He also highlighted efforts to secure domestic demand for "clean and made-in-Europe chemicals". The commission will align fertilizer registration rules with the EU's REACH chemicals framework, applying standard REACH provisions and streamlining the assessment of micro-organisms used in fertilizers. Officials said the changes will maintain safety and agro-economic efficiency standards while allowing a broader range of micro-organisms. For ETS indirect cost compensation, the commission plans to expand the list of eligible chemicals — including organic chemicals and fertilizers — but must first update existing state aid guidelines, a senior EU official said.

US to lay out tariff demands in coming days: Trump

US to lay out tariff demands in coming days: Trump

London, 4 July (Argus) — The US will lay out its tariff demands on foreign trade partners in the coming days, President Donald Trump said today. From tomorrow, 5 July, Trump will send letters to 10-12 countries a day, with the aim that all countries will be "fully covered" by 9 July, Trump said. That rate will not cover the amount of tariff deals still to be done by the US, which to date has struck three deals — of 10pc with the UK and China and of 20pc with Vietnam. "[The tariffs will] range in value from maybe 60pc or 70pc tariffs to 10pc and 20pc tariffs," Trump said. Countries will start paying them on 1 August, he said. Since 5 April Washington has been charging a 10pc extra tariff on imports — energy commodities and critical minerals are exceptions — from nearly every foreign trade partner, and those rates could go higher after 9 July. Trump has justified those tariffs by citing an economic emergency caused by allegedly unfair trade practices in foreign countries, and his administration is engaged in talks with foreign governments with the nominal goal of lowering their trade barriers.
