Let's talk about the new Trump tariff

What It Covers

Following the Supreme Court's 6-3 ruling striking down Trump's IEPA tariffs, the administration pivoted to Section 122 of the Trade Act of 1974, imposing a 15% tariff expiring in 150 days. The episode examines legal constraints, business impacts, refund prospects, and parallel shifts in labor markets and battery storage growth.

Key Questions Answered

• •Section 122 Tariff Limits: The new 15% tariff authority under Section 122 carries strict constraints: it cannot exceed 15%, expires after 150 days unless Congress extends it, applies uniformly across all countries, and requires only a presidential assertion of a balance-of-payments crisis — no national security or unfair trade justification needed. This makes targeted country-specific retaliation legally impossible under this statute.
• •Effective Tariff Rate Calculation: Businesses should plan around an average effective tariff rate of just under 13% for the next 150 days, dropping to under 7% afterward. That compares to over 26% under the now-struck IEPA tariffs. Key exemptions include USMCA goods, pharmaceuticals, critical minerals, food imports, and products already protected by steel, aluminum, and auto tariffs.
• •Tariff Refund Prospects: Businesses that paid IEPA tariffs face a complex legal path to refunds. Because importers — not end consumers — pay tariffs directly to the government, any court-ordered refunds would flow to those importers, not retail customers. Small businesses pursuing refunds should engage legal counsel and trade advocacy organizations, as individual litigation appears to be the primary viable route.
• •Auto Loan Interest Deduction: A new tax deduction covers interest paid on loans for new US-assembled vehicles purchased between 2025 and 2028, phasing out for single filers earning above $100,000 and joint filers above $200,000. Estimated savings range from $200–$700 depending on income bracket. Only roughly 30% of new vehicle buyers qualify, limiting its market-moving impact on dealership sales volume.
• •Labor Market Job-Switching Premium: The pay premium for switching jobs has collapsed from 8% in 2022 to under 2% today. Workers currently changing jobs are disproportionately involuntary switchers — laid-off workers struggling to find comparable roles. Overall wage growth remains above early-2010s levels but is declining for both job stayers and switchers, reducing negotiating leverage across the board.
