Assofermet, Italy's steel traders association, demands European Commission grant transitional CBAM exemptions for steel imports from January 2026 until five months after final Benchmark & Default Value parameters publication. The association warns regulatory uncertainty prevents operators from calculating 2026 supply costs, as definitive parameters likely emerge only in first quarter 2026 while related charges crystallize in February 2027. This informational lacuna forces companies to operate blindly, risking severe economic repercussions across European steel, aluminum, & manufacturing supply chains. Market participants estimate CBAM costs for low-emission producers at €30-60 per metric ton, though absent finalized parameters, these remain speculative approximations.
