Sheet and plate prices continued to inch higher on a combination of scarce spot tons, long lead times, lean inventories, and stable demand.
US steel exports eased 3% from August to September, marking the third consecutive monthly decline following June’s 17-month high, according to recently released US Department of Commerce figures. Exports have been historically low since early 2025 and remain weak compared to volumes seen in prior years. In September, 615,000 short tons (st) of steel were shipped outside of the country, 2% below the average monthly export rate of the past twelve months. September trade was 3% higher than the same month of 2025, 19% lower than September 2024, 21% lower than September 2023, and 15% lower than September 2022. For context, exports fell to a five-year low of 469,000 st in December and reached a near-five-year high of 914,000 st in May 2023.
Final import data for September from the US Commerce Department shows a slight decline from August’s 15-month high. And October’s license count suggests another month-on-month (m/m) decline in imports. September imports of 2,416,717 short tons (st) were down just 1% from 2,434,108 st in August, a 15-month high. October license data show a steeper 8% m/m fall to 2,214,730 st (Figure 1, left). August appears to have been the peak for the recovery in imports, which has been ongoing since February of this year, when we saw some of the lowest levels since 2020.
Algoma Steel has secured a contract to supply up to 24,000 metric tons of structural steel plate for Seaspan Shipyards’ Canadian Coast Guard icebreaker program. The agreement, valued at about $182 million Canadian, covers steel for up to six multi-purpose icebreakers, at ~4,000 metric tons per vessel. Algoma will produce the plate, with Stigterstaal Canada serving as the marine steel processing and distribution partner. The order is the largest polar-class steel order in Algoma’s history, according to the companies.
After an annual administrative review, the US Department of Commerce is adjusting the countervailing duties (CVDs) on imports of cut-to-length carbon-quality steel plate from South Korea. For the 2024 calendar year, Commerce set CVDs of 1.89% for Dongkuk Steel Mill and 1.39% for Hyundai Steel, according to a Federal Register announcement. The rates have changed slightly from the prior year review: Dongkuk's is down from 2.21% and Hyundai's is up from 1.31%. The cash deposit rate for all other companies remains 3.26%.
Sheet prices soared this week as market participants increasingly predict that the strong market characterizing 2026 will stretch well into 2027. And with extremely limited spot availability, mills that have spot tons to sell are charging a significant premium, they said. The result: Sheet prices saw their highest week-over-week gains since March 2025, according to SMU's pricing records. That's when President Trump shocked the market by expanding Section 232 tariffs to cover traditional US allies such as Canada, Mexico, and the EU.
