Research Methodology

Desk research of customs/trade data, SEC 10-K filings, and MIIT efficiency mandate documentation preceded structured interviews with tier-1 supplier procurement directors, OEM platform engineers, rapid-solidification metallurgists, and electrical steel mill technical sales leads. Primary fieldwork combined with secondary validation from IHS Markit vehicle production databases and IEA critical mineral supply reports. Bottom-up segment sizing triangulated against top-down market value estimates across material type, component application, and regional production cluster dimensions.

Variance decomposition isolates volume, price, and mix effects across the projection horizon. Segmentation dimensions modeled include material grade tier, switching frequency requirement, propulsion architecture, and regional regulatory framework. CAGRs derive from elasticity-adjusted adoption curves for 800V systems and carbon-border adjustment mechanism phase-in assumptions.
