Section 232 reset: Supplier data is key to reduced tariff treatment

When Section 232 tariffs on steel and aluminum underwent restructuring in April 2026, the changes extended well beyond rate adjustments.

This white paper explores how that shift turns supplier-origin documentation into a compliance requirement. It shows how a structured supplier solicitation process replaces manual, email-based collection with a repeatable, auditable workflow, helping trade teams reduce unnecessary duty exposure and demonstrate reasonable care during U.S. Customs and Border Protection (CBP) audits. 

What you'll learn: 

• How the April 2026 restructuring changed tariff tiers, full-value duty calculations, and copper's role in Section 232 

• Why reduced tariff treatment now depends on metal-origin documentation that most suppliers have never tracked 

• How Executive Order 14411 raises the bar on importer of record documentation and customs enforcement 

• A three-part framework for building a defensible, audit-ready supplier solicitation process 

As enforcement intensifies and documentation requirements deepen, organizations relying on manual, ad hoc supplier outreach face growing exposure to overpaid duties, audit findings, and compliance gaps.
