Domestic raw steel mill production declined last week to low levels not seen since early last year, according to the latest figures released from the American Iron and Steel Institute (AISI).
Total US steel mill raw output was estimated to have been 1,646,000 short tons (st) in the week ending Sept. 28. This is down 61,000 st, or 3.6%, from the week prior. The last time raw production was this low was in January 2023.
Raw production last week was 4.3% lower than the year-to-date weekly average of 1,721,000 st. Production is down by 2.7% compared to the same week one year earlier when mill output totaled 1,691,000 st.
The mill capability utilization rate last week declined to 74.1%. This is off from 76.9% one week prior and down from 74.4% this time last year.
Year-to-date production stood at 66,212,000 st at a capability utilization rate of 76.7%. This is 1.7% less than the same time frame last year, when 67,325,000 st had been produced at a capability utilization rate of 76.9%.
Weekly production by region is shown below, with the weekly changes noted in parentheses:
- Northeast – 116,000 st (down 9,000 st)

- South – 710,000 st (down 32,000 st).
- West – 47,000 st (down 6,000 st)

Leibowitz: Tariffs are the trade version of going nuclear
In short, when tariffs go up, jobs in consuming industries go down. There is conclusive evidence from past actions: safeguard tariffs in 2002 and Section 232 tariffs in 2018. It is happening again in 2025.
