The Thai Industrial Standards Institute (สมอ.) takes its draft revision of TIS 24 (rebar) to the Industrial Standards Committee (กมอ.) on 18 Aug 2026. The key question is whether production must be limited to basic oxygen (BOF) and electric arc (EF) furnaces, which would exclude induction furnace (IF) steel. The draft also raises grades from 3 to 10, adds sizes up to DB50, and tightens fatigue, bend and chemistry tests. Rebar buyers, builders and contractors should watch the outcome for supply and price changes. Steel mills with IF lines face investment costs, and a Thai MP has called for tax support if they must switch, but no delay of the standard.
