US PVC producers weigh cutbacks on lower margins
US PVC producers weigh cutbacks on lower margins
Houston, 30 January (Argus) — US polyvinyl chloride (PVC) producers are weighing operation cutbacks in February after grappling with deteriorating sales margins underpinned by elevated feedstock costs and stagnant end-product values. PVC producer profitability eroded in January as prices for key feedstock ethylene leapt to four-month highs by mid-January, various sources said. Ethylene is a main component in ethylene dichloride (EDC) manufacturing, which is then cracked into vinyl chloride monomer (VCM) before being converted into PVC. Some domestic PVC production is fully integrated and feature ethylene crackers, but many producers still purchase spot or contract ethylene and remain exposed to price fluctuations in the spot market. Spot US ethylene prices to-date in January have averaged 18pc higher than in December and 66pc higher than in January 2024, according to Argus data. Meanwhile, PVC spot values in Houston appreciated at a much slower rate between December and January, climbing by 1pc. Elevated ethylene spot prices are expected to persist in the near-term, maintaining pressure on PVC margins, due to planned maintenance and recovery from unplanned shutdowns in mid-January stemming from sub-freezing temperatures that gripped the US Gulf coast. The expectation for ethylene values to persist at current levels is anticipated to result in PVC production cutbacks, according to several exporters. Some producers, though, remain incentivized to maintain operating rates after bringing online expanded capacity last year. Formosa and Shintech collectively brought more than 500,000 metric tonne (t)/year of new PVC capacity on line during the second half of 2024. The ramp up in added capacity coincided with increasing trade barriers into key offshore destinations, which is expected to keep more volumes within the US while consumer demand outlooks this year remain cautiously optimistic . US buyers are unsure if domestic demand will be strong enough in 2025 to absorb additional volume, placing a ceiling on upward price direction. Exporters are even less optimistic operating in a global market increasingly defined by anti-dumping duties and plentiful Chinese supply. Domestic contract negotiations have highlighted the contrast between higher operating costs and a well-supplied PVC market. Producers cited higher operating costs to argue against lower contract negotiations in January, especially after prices fell in October and November. Several producers announced increases for February volumes, with some rising as high as 5¢/lb. But buyers said current demand does not support increases and instead view price hikes as to recapture lost margin. While producers sought price stability for January monthly contracts, they are also competing to lock in volume commitments through 2025 with aggressive annual contract discussions. Producers are trying to establish a price floor domestically by limiting price erosion among already-low-priced customers, but the additional capacity has made steeper price concessions difficult to avoid in other instances. One evolving upstream market variable is a firmer US Gulf coast spot export caustic soda market, which could encourage producers to maintain current rates and delay any cuts. Integrated PVC producers also manufacture chlorine and caustic soda through chlor-alkali units. Caustic soda is a co-product of chlorine — the latter a key feedstock in EDC production — and price swings in chlorine or caustic soda values can influence production decisions for PVC manufacturers. Caustic soda export prices from the US Gulf coast this week rose by $10/dry metric tonne (dmt) from the prior week and remains 8pc higher than the same week last year, according to Argus data. Tightened spot supply availability is a tailwind for spot values in the near-term, but values remain 24pc lower than peak levels in September when caustic soda prices last offset tighter PVC margins.

Global Li-ion battery shipments rise in 2024: EV Tank
Global Li-ion battery shipments rise in 2024: EV Tank
Beijing, 6 January (Argus) — Global shipments of electric vehicle (EV) power batteries and energy storage batteries surged in 2024, and could continue growing until 2030, according to Chinese research institution EV Tank. Global EV power battery shipments increased by 22pc on the year to 1,051GWh in 2024. This was mainly driven by continued rises in China's EV sales, which were supported by government incentives such as old vehicle trade-in subsidies, outpacing a slowdown in European and US markets caused by weakening economies and rising inflation. Global shipments of energy storage batteries rose by 65pc over the same period to 370GWh, supported by China's government-led promotion of energy storage systems in wind and solar industries, falling manufacturing costs, as well as firm physical demand in the US and effects from its investment tax credit. GWh-level orders from some emerging markets such as UK, Saudi Arabia and Australian also grew over 2024. Global total shipments of lithium-ion batteries increased by 29pc from a year earlier to 1,545GWh in 2024, including 1,215GWh in China that rose by 37pc on the year and accounting for 79pc of the total. Continued demand growth in China and the country's elevated investment in overseas production boosted global shipments. EV Tank forecasts global lithium-ion battery shipments will rise to 1,899GWh in 2025 and 5,127GWh in 2030. It also estimates China's shipments of sodium-ion battery shipments to more than double to 2GWh in 2024 from 0.7GWh in 2023. But this was far below earlier expectations of 3 GWh/yr, because of higher manufacturing costs for sodium-ion batteries compared with ternary and lithium iron phosphate lithium-ion batteries and lead-acid batteries. Consecutive falls in lithium carbonate feedstock prices in the past couple of years, mainly caused by rapid supply expansions, have reduced manufacturing costs for lithium-ion batteries. Current average manufacturing costs for lithium-ion batteries fell to 0.50 yuan/Wh as of June 2024, lower than Yn0.60/Wh for the sodium-ion battery, according to EV Tank.

US rail group optimistic about 2025 rail demand
US rail group optimistic about 2025 rail demand
Washington, 12 December (Argus) — US rail volume is likely to start strong in 2025, but railroads will need to navigate changing federal policies, the Association of American Railroads (AAR) said. Volume next year hinges on a few key factors, including the resilience of consumer spending, strength in the labor market, and the trajectory of inflation and interest rates, the group said. Railroads will need to remain vigilant as these economic indicators will be critical in helping assess rail traffic and broader economic health in the months ahead, AAR said. "Strong intermodal growth and stable consumer demand offers reasons for optimism," AAR said. "But railroads and the economy alike must navigate evolving policies and potential disruptions" as the US enters 2025 under a new administration, the group said. The AAR'S optimism comes as rail traffic in November "while by no means stellar, suggests that the broader economy remains on stable footing", AAR said. US intermodal rail volume set new records in November. The increase reflected strong consumer demand following job gains that pushed increased spending, AAR said. Intermodal traffic is made up primarily of consumer goods shipped in containers between different modes of transportation, although some scrap metal and specialty agriculture products ship this way. US railroads loaded an average of 282,000 intermodal containers and trailers per week, up by 11pc from a year earlier. That was the highest weekly average for any November since AAR began tracking intermodal data in 1989. Carload traffic fell by 3.8pc compared with November 2023. Carload traffic is primarily made up of commodities. Coal was the "biggest problem", AAR said. US railroads loaded 15pc less coal last month compared with a year earlier, while year-to-date loadings were down by 14pc from the same 11 months in 2023. If coal were excluded, monthly US carload traffic in November would have notched a 10th consecutive year-on-year increase. Industrial products volume was down by 1pc from a year earlier. Manufacturing is a major driver of US carload traffic, and that sector remains sluggish, AAR said.

Talks to restart as port of Vancouver lockout drags
Talks to restart as port of Vancouver lockout drags
Calgary, 8 November (Argus) — A labour disruption at the port of Vancouver is now into its fifth day, but the employers association and the locked-out union are to meet this weekend to try to strike a deal and get commodities moving again. Workers belonging to the International Longshore and Warehouse Union (ILWU) Local 514 on Canada's west coast have been locked out by the BC Maritime Employers Association (BCMEA) since 4 November. This came hours after the union implemented an overtime ban for its 730 ship and dock foreman members. The two sides will meet on 9 November evening with the assistance of the Federal Mediation and Conciliation Service (FMCS) in an effort to end a 19-month long dispute as they negotiate a new collective agreement to replace the one that expired in March 2023. The FMCS was already recruited for meetings in October, but that did not culminate in a deal. Natural resource-rich Canada is dependent on smooth operations at the port of Vancouver to reach international markets. The port is a major conduit for many dry and liquid bulk cargoes, including lumber, wood pellets and pulp, grains and agriculture products, caustic soda and sodium chlorate, sugar, coal, potash, sulphur, copper concentrates, zinc and lead concentrate, diesel and renewable diesel liquids and petroleum products. These account for about two-thirds of the movements through the port. Grain operations and the Westshore coal terminal are unaffected while most petroleum products also continue to move, the Port of Vancouver said on 7 November. As the parties head back to the bargaining table, the ILWU Local 514 meanwhile filed a complaint against the BCMEA on 7 November, alleging bargaining in bad faith, making threats, intimidation and coercion. "The BCMEA is trying to undermine the union by attempting to turn members against its democratically-elected leadership and bargaining committee, said ILWU Local 514 president Frank Morena on 7 November. "They know their bully tactics won't work with our members but their true goal is to bully the federal government into intervention." But that is just "another meritless claim," according to the BCMEA, who wants to restore supply chain operations as quickly as possible. The union said BC ports would still be operating if the BCMEA did not overreact with a lockout. "They are responsible for goods not being shipped to and from BC ports — not the union," Morena says. The ILWU Local 514 was found to have bargained in bad faith itself already, according to a decision by the Canada Industrial Relations Board (CIRB) in October. Billions of dollars of trade are at risk with many goods and commodities at a standstill at Vancouver, which is Canada's busiest port. A 13-day strike by ILWU longshore workers in July 2023 disrupted C$10bn ($7.3bn) worth of goods and commodities, especially those reliant on container ships, before an agreement was met.
