2026 did not deliver tariff certainty. It delivered a Supreme Court ruling that wiped out one entire class of tariffs — and then a new 10% import surcharge 24 hours later.
The IEEPA tariffs that defined U.S. trade policy since early 2025 were struck down on February 20, 2026 in Learning Resources, Inc. v. Trump — a 6-3 decision that found the president lacked authority to impose tariffs under IEEPA. By February 24, they were gone. By February 20, the same day, a new 10% temporary import surcharge was issued under Section 122 of the Trade Act of 1974. Section 301 tariffs on Chinese goods, steel and aluminum Section 232 tariffs, and country-specific duties remain in force under separate legal authority.
For supply chain leaders, this is not relief. It’s a different kind of uncertainty — one that makes the strategic question harder, not easier. The companies that are navigating this best are not the ones who predicted what tariffs would do next. They’re the ones who built supply chains that don’t require that prediction to function.
What the data shows in 2026:
- 82% of supply chain leaders reported their supply chains were affected by new tariffs (McKinsey, May 2025 survey of 100 SCM leaders)
- 73% expect to hit their “tariff absorption wall” by end of 2026 — the point where costs must move from corporate balance sheets to consumer prices (MHI / Tradeverifyd 2026)
- 60% say a 10% tariff increase would force immediate price hikes (EY / Tradeverifyd 2026)
- U.S. imports from China dropped ~20% in 2025 alone and have returned to near-2001 levels (Harvard Business School / Laura Alfaro, April 2026)
- Mexico became the top U.S. import source in 2025 and attracted a record $40.87B in FDI in 2025, up 10.8% year-over-year (3PL Center / Kearney FDI Confidence Index 2026)
- 62% of American companies are considering or already relocating part of production to Mexico (Deloitte)
- Vietnam, India, and Mexico face new Section 301 scrutiny in 2026 — the alternatives are not immune

The Tariff Landscape Nobody Predicted — And What It Actually Looks Like Now
The conventional forecast for 2026 was either “tariffs stay high” or “tariffs come down.” Neither quite happened.
What actually happened was more complicated: the Supreme Court invalidated the legal foundation for the broadest tariffs, the administration pivoted to a different legal authority within hours, and the underlying trade tension between the U.S. and its major trading partners didn’t change at all.
Here’s the timeline that supply chain leaders need to understand:
April 2, 2025 — “Liberation Day” The Trump administration announced sweeping reciprocal tariffs under IEEPA authority. Tariffs on Chinese goods reached 145%+ on some categories. New duties hit dozens of trading partners. Supply chain teams scrambled to model the impact.
August 2025 — Federal Circuit Rules The U.S. Court of Appeals for the Federal Circuit ruled that IEEPA does not authorize tariff imposition — a decision that set the stage for the Supreme Court.
February 20, 2026 — Supreme Court Decision In Learning Resources, Inc. v. Trump, the Supreme Court held 6-3 that IEEPA does not authorize the president to impose tariffs. Chief Justice Roberts wrote the majority opinion. The IEEPA tariffs — the reciprocal tariffs, fentanyl-related tariffs on Canada, China, and Mexico — were declared unlawful.
February 20, 2026 — Same Day President Trump issued a Proclamation under Section 122 of the Trade Act of 1974 imposing a 10% “temporary import surcharge” on imports broadly. Section 122 authority has a 150-day statutory limit.
February 24, 2026 — IEEPA Tariffs Terminated All IEEPA-based tariffs terminated at 12:00 am ET. CBP halted collection. The question of refunds for previously paid IEEPA tariffs was remanded to the Court of International Trade — a process expected to take months or longer, involving more than $166 billion in previously collected duties.
What remains in force:
- Section 301 tariffs on Chinese goods (imposed under trade authority separate from IEEPA)
- Section 232 tariffs on steel and aluminum
- The new 10% Section 122 surcharge (subject to the 150-day limit and legal challenge)
- Country-specific and product-specific duties under various other authorities
The net result: tariff pressure has not ended. The legal mechanism has changed. The average effective tariff rate on Chinese goods — which reached near 17%, the highest since 1932 — has shifted, but Section 301 alone keeps meaningful cost differentials in place for many product categories.
The “Great Reallocation” — What the Trade Data Actually Shows
Harvard Business School Professor Laura Alfaro and Dartmouth Professor Davin Chor documented what they called the “great reallocation” in April 2026 research: U.S. imports from China have returned to near-2001 levels — back to where they were when China entered the WTO.
This didn’t happen overnight. The shift accelerated in 2025, but the foundations were laid years earlier. Companies that had been quietly building China+1 supplier relationships since the first round of Section 301 tariffs in 2017-2018 were positioned to move faster than companies that waited.
The reallocation is not moving to a single replacement source. It’s moving to a different source depending on what’s being made. And increasingly, the companies managing the transition most effectively are pairing sourcing diversification with agentic AI in their supply chain operations — using autonomous systems to maintain visibility across a more fragmented supplier network.
| Product Category | Primary Shift Destination | Key Driver |
|---|---|---|
| Consumer goods, apparel | Vietnam | Labor cost + established manufacturing base |
| Electronics assembly | Vietnam, Malaysia | Existing supplier ecosystem |
| Automotive, aerospace | Mexico (Nuevo León, Jalisco, Querétaro) | USMCA + 4–8 day truck transit to U.S. DCs |
| Pharmaceuticals, chemicals | India | PLI (Production Linked Incentive) subsidies |
| Semiconductor, medical devices | Malaysia | Established precision manufacturing base |
| FMCG, medical devices | Mexico | Speed-to-market + USMCA duty-free access |
The pattern, as Euro-American Worldwide Logistics documented in June 2026: “diversification away from China has stopped being a question of strategy and started being a question of execution.”
The Three Sourcing Strategies Companies Are Actually Using
Not every company can or should fully exit China manufacturing. The three strategies below reflect what’s actually being deployed, with their real trade-offs documented from 2025-2026 operations.
Strategy 1 — China+1 (Split Production)
Keep China for commodity components where the supply chain depth is irreplaceable. Add a second manufacturing footprint in a lower-tariff jurisdiction for finished goods or high-tariff components.
Who it fits: Companies with complex component dependencies on China’s supplier ecosystem that can’t be replicated elsewhere in a short timeframe.
Real trade-off: A U.S. auto parts importer cited in GrowthHQ’s 2026 analysis transitioned wiring harness production from China to Mexico. Result: circumvented 25% China tariffs and cut landed costs by 12%. Cost: lead times increased 40% during ramp-up due to labor shortages and quality ramp issues. Split production reduces tariff exposure but increases operational complexity.
One thing people underestimate: The “China fills up with capacity” problem. As Thomson Reuters’ trade advisor Rowden noted in the 2026 Global Trade Report: “The knee-jerk reaction for many companies is to say, ‘Okay, we’ll just move out of China into Southeast Asia,’ but that is filling up with capacity.” Vietnam’s industrial parks in key provinces are already at or near capacity for some product categories.
Strategy 2 — Nearshoring to Mexico (North American Redesign)
Shift final assembly or manufacturing to Mexico under USMCA, gaining tariff-free access to the U.S. market and dramatically shortened transit times.
Who it fits: Companies where speed-to-market and inventory agility matter more than lowest unit cost, and whose product categories have established Mexican manufacturing capacity.
The numbers: Mexico-to-U.S. DC transit time is 4–8 days by truck from Monterrey or Juárez. Vietnam or India to U.S. by ocean: 25–35 days. Industrial real estate in Mexico: approximately $0.45–$0.80 per square foot per month (triple net) in key manufacturing zones, versus $0.85–$1.20 in comparable Texas locations.
What the data shows: Mexico attracted a record $40.87 billion in FDI in 2025, up 10.8% year-over-year. Industrial vacancy in primary hubs like Monterrey, Guadalajara, and Mexico City remains below 4%. Deloitte found 62% of American companies either considering or already relocating part of production to Mexico.
Real trade-off: Higher wage floors than Southeast Asia. Capacity constraints in skilled labor, particularly for complex electronics assembly. Border variability at high-volume crossings when CBP shifts inspection priorities. And the 2026 USMCA joint review — which formally launched in March with technical talks set for July 1 — could reset rules of origin and tighten China-content limits in ways that affect nearshoring economics.
For a detailed breakdown of nearshoring economics by country, see Nearshoring Is the New Offshoring: The Business Case for Mexico, Vietnam, and Eastern Europe.
The Section 301 wildcard: A new Section 301 investigation launched in 2026 includes not just China but 13 other countries — including Vietnam, India, and Mexico — under scrutiny for “excess capacity” in key sectors. If the investigation results in tariff extension to today’s alternative manufacturing hubs, the calculus changes again.
Strategy 3 — Regional Hub Model (Multi-Polar Manufacturing)
Design the supply chain around regional hubs: one for North American demand, one for European demand, one for Asian demand. Each hub sources primarily from within its region, minimizing cross-regional tariff exposure.
Who it fits: Large multinationals with demand spread across regions and the capital to build or acquire manufacturing capacity in multiple geographies.
The trend: Logistics analysts in the nShift 2026 analysis described the emerging reality as a “multi-polar manufacturing world where production is distributed across regional hubs to minimize geopolitical and climate-related risks.” China still produces more than 70% of the world’s iPhones and retains the deepest component-supplier ecosystem — full decoupling is a longer-term project than most timelines assume.
The Landed Cost Calculation That Most Companies Are Getting Wrong
“Moving to Vietnam cuts my costs” is a conclusion that requires a landed cost model, not a tariff comparison.
Landed cost = manufacturing cost + freight + duties + insurance + compliance costs + inventory-in-transit carrying costs + quality ramp costs
Here’s where companies repeatedly make the error: they compare unit manufacturing cost in the new country against unit manufacturing cost in China, see a number they like, and call it a win. The full model looks different.
| Cost Component | China (Current, Section 301) | Mexico | Vietnam | India |
|---|---|---|---|---|
| Ocean/road freight to U.S. DC | Low (established lanes) | Very Low (4–8 day truck) | High (25–35 day ocean) | High (25–35 day ocean) |
| Tariff exposure | High (Section 301 in force) | Low (USMCA duty-free for qualifying) | Low-Medium (potential Section 301 scrutiny) | Low-Medium (PLI subsidies offset some) |
| Safety stock requirement | Medium | Low (short transit = tight reorder) | High (long transit = buffer stock) | High |
| Labor cost per unit | Low-Medium | Medium-High | Low | Low |
| Supplier ecosystem depth | Very High | Medium (strong in automotive/aero) | High (consumer goods, electronics) | Growing (pharma, chemicals) |
| Rules of origin complexity | High | Medium (USMCA requirements) | Medium-High | Medium |
| Ramp-up lead time | N/A (established) | 6–18 months | 12–24 months | 18–30 months |
The Unicargo May 2026 analysis put it plainly: “The companies winning with Mexico are not the ones chasing the lowest unit cost. They are the ones designing for speed.”
The IEEPA Refund Process — What Importers Need to Know
For companies that paid IEEPA tariffs between February 2025 and February 24, 2026, a refund process exists — but it is not straightforward.
The U.S. Court of International Trade issued an order on March 4, 2026 directing CBP to issue refunds via normal administrative procedures. Two days later, CIT Judge Eaton suspended that order to allow CBP time to develop a refund process through its Automated Commercial Environment (ACE) system. The process is ongoing and is expected to be complex, potentially involving more than $166 billion in previously collected duties.
What this means practically:
- Importers may be entitled to refunds for IEEPA duties paid — but the timing and mechanics are unresolved
- Companies should preserve records of all entries subject to IEEPA tariffs
- The refund process will likely require engagement with a licensed customs broker or trade attorney
- New tariffs under other authorities (Section 122, Section 301, Section 232) remain in force and are not affected by the IEEPA ruling
This is an active legal and regulatory situation. Verify current status with a licensed customs broker or trade attorney before filing any refund claims. The information above reflects conditions as of July 2026 and may have changed.
The Five Decisions That Determine Your Tariff Resilience
Supply chain leaders who reviewed their tariff exposure in 2026 generally found that vulnerability concentrated in five decision points — most of which were made years before tariffs became a concern.
1. Where is your HS code concentration? Every product category has a tariff rate tied to its Harmonized System code. A single HS-code reclassification can move a product from a manageable tariff rate to a prohibitive one. Companies that have mapped their full HS code exposure by country of origin are starting from a much stronger position than those who haven’t.
2. How deep is your China supplier dependency — really? “We only source 20% from China” is often true for first-tier suppliers and false when second and third-tier components are counted. Tariff vulnerability follows component origin, not finished goods origin. Tracing material origin to tier 3 and beyond is where most of the hidden exposure sits.
3. Do your contracts have tariff clauses? Force majeure clauses in most commercial contracts were not written to cover tariff volatility. Companies that added tariff adjustment clauses, cost-sharing provisions, or material adverse change definitions to new supplier contracts in 2024-2025 have substantially more flexibility than those who didn’t. Review existing contracts for how tariff cost increases are allocated.
4. What is your Section 301 exposure if Vietnam/India alternatives face new duties? The 2026 Section 301 investigation into “excess capacity” in 13 countries changes the risk calculus for China+1 strategies. Companies that moved production to Vietnam or India to escape China tariffs should model the scenario where those destinations face new Section 301 duties — and understand what their options are at that point.
5. Is your customs classification defensible? Classification disputes with CBP are expensive and slow. Companies that have obtained binding rulings on key products have legal certainty. Those who are relying on informal classification practices carry audit risk that becomes significant when CBP shifts enforcement priorities.
Frequently Asked Questions
What happened to U.S. tariffs in 2026 — did they go away? Partly. The Supreme Court struck down IEEPA-based tariffs on February 20, 2026 in Learning Resources, Inc. v. Trump, a 6-3 decision finding the president lacked authority to impose tariffs under IEEPA. All IEEPA tariffs terminated on February 24, 2026. However, President Trump issued a new 10% import surcharge under Section 122 of the Trade Act of 1974 on the same day as the ruling. Section 301 tariffs on Chinese goods, Section 232 steel and aluminum tariffs, and other country-specific duties remain in force under separate legal authority. Tariff pressure has not ended — the legal mechanism changed.
What is the China+1 strategy and is it still viable in 2026? China+1 means maintaining manufacturing in China while developing a second production footprint in at least one other country. In 2026, it is no longer a hedge for most large multinationals — it has become the standard operating model. The viability question has shifted: as Vietnam and India absorb more manufacturing, capacity constraints are emerging. The 2026 Section 301 investigation into “excess capacity” in Vietnam, India, Mexico, and 10 other countries also means today’s China+1 destinations may face new tariff scrutiny. Companies evaluating China+1 destinations should model the Section 301 scenario, not just current tariff rates.
Is Mexico the best alternative to China for U.S. companies? For North American demand and speed-sensitive supply chains, Mexico is the strongest option available in 2026. USMCA duty-free access and 4–8 day truck transit to U.S. distribution centers are advantages that Vietnam and India cannot match on logistics speed alone. The trade-offs are higher wage floors than Southeast Asia, capacity constraints in skilled labor for complex manufacturing, and the ongoing USMCA joint review (formal technical talks began July 1, 2026) which could tighten rules of origin. Mexico is not automatically the right answer — it depends on your product category, demand geography, and labor requirements.
Can companies get refunds for IEEPA tariffs already paid? Potentially. The U.S. Court of International Trade issued an order in March 2026 directing CBP to process refunds through normal administrative procedures. That order was temporarily suspended to allow CBP to develop a process through its ACE system. The refund process is ongoing, the mechanics are unresolved, and more than $166 billion in previously collected duties is at stake. Companies should preserve all records of IEEPA tariff payments and consult a licensed customs broker or trade attorney to understand their specific eligibility and filing requirements. Do not rely on this article as legal guidance — this is an active regulatory situation.
What is the single most important thing a company should do now to improve tariff resilience? Map your full component origin to tier 3 suppliers — not just tier 1. Most tariff vulnerability in complex supply chains lives in components, not finished goods. A company that sources finished goods from Vietnam may still have 60-70% of its component value originating in China, subject to Section 301 duties at whatever tier of the supply chain those components enter. Until you have a complete picture of origin by HS code down to tier 3, you don’t know your actual exposure. This mapping exercise consistently surfaces surprises that high-level supplier lists don’t show.
