    AISI: Domestic mill output at lowest rate since March

    Written by Brett Linton

    Total US raw steel mill production declined last week to the lowest rate seen in over five months, according to the latest figures published by the American Iron and Steel Institute (AISI). Production has trended lower since peaking in May but remains historically strong.

    Domestic production was estimated at 1,808,000 short tons (st) in the week ending Sept. 5, down 10,000 st or 0.6% from the previous week (Figure 1). This year we have seen weekly production as high as 1,898,000 st in May (a six-year high) and as low as 1,704,000 st in the first week of the year.

    Imports fall back slightly in September, slide further in October

    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.

    Mexican longs producer Deacero has cast the first billet at its new minimill in Ramos Arizpe, Mexico, moving the Danieli-supplied caster into commissioning. It's a key milestone for Deacero's $600-million Ramos II mini-mill, said Italian plant engineering and equipment provider. "The achievement further strengthens the long-standing collaboration between Deacero and Danieli, and further confirms Danieli’s already-established presence in the Mexican long-products market," the company said in a statement on Nov. 2.
