SEMUDMEX – Strategic Customs, Trade & Regulatory Advisory
I. UNITED STATES – Structural Tariff & CBP Developments
• U.S. Supreme Court Restricts Executive Tariff Authority under IEEPA (Official Supreme Court Opinion; Reuters 20-02-2026)
Technical & Legal Context: The Court ruled that IEEPA does not authorize broad tariff imposition without explicit Congressional delegation. This decision sets constitutional limits on executive trade authority, while Section 232 and 301 measures remain legally intact.
SEMUDMEX Strategic Risk Assessment: Exposure includes refund litigation, drawback recalculations, protest filings, and contractual disputes. Immediate review of liquidation status and historical tariff payments is recommended.
• Evaluation of Alternative Tariff Mechanisms – Section 232 / 301 (Reuters 23-02-2026; WSJ Analysis)
Technical & Legal Context: Policymakers are assessing alternative statutory bases to sustain tariff measures following the Court’s limitation under IEEPA.
SEMUDMEX Strategic Risk Assessment: Continued volatility expected. Importers must stress-test supply chain contracts and pricing structures under multi-scenario tariff exposure.
• CBP Electronic Refunds – ACH Implementation (Federal Register 2026)
Technical & Operational Context: CBP transitions certain refunds to electronic payments via ACH, affecting reconciliation workflows and broker coordination.
SEMUDMEX Strategic Risk Assessment: Misalignment in banking authorizations may delay or misapply refunds, generating accounting and compliance disputes.
• CBP Electronic Bond Transmission (eBond) – Enhanced Validation Controls (Federal Register 2026)
Technical & Operational Context: Formalization of electronic bond data standards increases scrutiny on bond sufficiency and transmission accuracy.
SEMUDMEX Strategic Risk Assessment: Bond discrepancies may block entries or delay releases. Bond health check recommended for high-volume importers.
II. MEXICO – Customs Reform & Digital Enforcement 2026
• RGCE 2026 – Reinforced Digital Evidence & File Integrity (SAT / DOF Publications)
Technical & Operational Context: 2026 rules consolidate documentary traceability requirements and tighten alignment between invoice, transport, and entry data.
SEMUDMEX Strategic Risk Assessment: Increased shipment holds and post-clearance reviews where electronic files lack consistency.
• Electronic Value Declaration (eMV) – Valuation Dossier Baseline (SAT / VUCEM Framework)
Technical & Operational Context: Structured valuation files now expected, including contracts, incrementables, related-party support and proof of declared value integrity.
SEMUDMEX Strategic Risk Assessment: Weak valuation support elevates exposure to estimated value triggers and retroactive duty assessments.
