Methodological Framework

Trade statistics from customs authorities, national steel association production databases, and regulatory filing repositories formed the secondary backbone, cross-referenced with primary interviews involving continuous casting plant managers, rebar mill procurement leads, construction consortium supply chain directors, and automotive tier-one supplier quality engineers. Bottom-up volume estimates from mill capacity utilization rates triangulated against top-down infrastructure budget disbursement data to anchor demand-side calibration.

Historical trendline analysis of billet-to-rebar margin spreads and carbon intensity benchmark adoption curves informed the projection framework across the analysis window. Segmentation modeling incorporated material type, production method, end-user application criticality, and dimensional specification bands. CAGRs derived from regression-weighted infrastructure investment trajectories and regulatory compliance cost curves, with specific inputs from EU CBAM duty phase-in schedules and Indian PLI scheme capacity addition timelines.

Inputs from continuous casting operators and construction procurement databases were available through the study window; gaps in real-time ferrous scrap inventory data and unannounced hydrogen-DRI pilot commissioning introduce uncertainty bands around electric arc furnace cost projections. Forecasts reflect assumptions on regulatory timeline adherence and infrastructure budget execution rates. A model refresh is warranted upon material change in EU CBAM carbon border duty implementation pace or Chinese MEE capacity consolidation enforcement intensity.
