Scrap quality gap pushes US steel buyers toward traceable supply

A May 2026 arXiv study on steel recycling documents widening quality gaps in mixed scrap streams, noting that US automotive and appliance producers are shortening qualification cycles for suppliers who can prove chemistry and contamination controls.

Mills serving Detroit and Gulf Coast auto lines are requesting batch-level traceability on high-quality scrap and flat-rolled inputs; industry estimate puts alternate-source qualification at 8–12 weeks when melt-shop audits are required.

Flat steel products and high-quality scrap and automotive-grade steel coils are the categories where provenance documentation now gates spot allocation.

Exporters should map chemistry certificates, radiographic screening where applicable, and heat-number continuity for any secondary flat-rolled supply offered to US service centers.

Prioritise steel service center procurement managers, mini-mill buyers, and tier suppliers auditing melt sources for North American auto programs.

Recyclers with sorted busheling and shredded streams that can pass mill chemistry windows are receiving RFQ callbacks faster than mixed-grade brokers.

Lead with heat-number traceability packs, contamination test summaries, and direct-supply programs that bypass commingled yard risk.

Note that missing chemistry continuity on a trial heat typically triggers a 90-day disqualification from auto-facing service center approved vendor lists.
