A year ago, near-shoring electronics manufacturing to North America was a strategic ambition. Today, for many OEMs in aerospace and defense, data centers, and industrial markets, it’s an operational necessity—and the window to act is narrowing.
Bloomberg recently reported that despite the sweeping tariff policies of 2025—including levies on Chinese imports peaking at 125%—U.S. electronics supply chains haven’t simply shifted back to American soil. Instead, production has migrated to Vietnam, Mexico, and other lower-tariff geographies, leaving OEMs with a familiar problem: long lead times, limited visibility, and fragile single-country dependencies.
For companies building mission-critical hardware—printed circuit board assemblies for defense platforms, control systems for data centers, assemblies for medical devices—that tradeoff is no longer acceptable.
The Real Cost of Offshore Isn’t on the Invoice
Supply Chain Management Review put it plainly in late 2025: reshoring has moved from a cost center to a core strategy. The companies winning aren’t the ones that avoided the tariff conversation—they’re the ones that used it to accelerate a transition they already knew they needed to make.
The math on offshore has changed. U.S. tariffs, rising Asian labor costs, cross-Pacific freight volatility, and geopolitical risk have eroded the cost advantage of distant production. What remains is a long list of hidden costs that never appear on the purchase order:
- Extended lead times that slow NPI cycles and new product introduction timelines
- Limited engineering collaboration across time zones and cultural barriers
- Reduced supply chain visibility at the PCBA and component level
- Compliance exposure in regulated industries like aerospace, defense, and life sciences
Intervala customers know that nearshoring to a U.S.-based electronics manufacturing services (EMS) partner addresses all of these—not just the tariff line.
Why the Aerospace, Defense, and Data Center Industries Are Moving First
Not all industries feel this pressure equally. For commercial consumer goods, the math may still favor offshore. But for three sectors Intervala knows well, the risk tolerance for a disrupted supply chain is essentially zero.
Aerospace and defense manufacturers face strict sourcing requirements, ITAR compliance obligations, and no margin for quality escapes. A PCBA failure on a defense system isn’t a warranty claim—it’s a mission risk. Proximity to the prime contractor, tight engineering collaboration, and supply chain traceability aren’t nice-to-haves. They’re program requirements.
Data center operators are scaling at a pace that demands a manufacturing partner who can match it. With AI infrastructure buildouts driving unprecedented demand for server boards, power systems, and networking hardware, uptime isn’t just a performance metric—it’s a revenue driver. Nearshore printed circuit board assembly (PCBA) means faster iteration, faster response to design changes, and a manufacturing partner who can be on-site when it matters.
Industrial equipment OEMs are navigating the same dynamics: shorter product lifecycles, more complex electronics integration, and customers who expect delivery performance that offshore supply chains simply can’t guarantee consistently.
What Nearshore EMS Actually Looks Like in Practice
Nearshoring isn’t just about geography. It’s about the quality of the manufacturing partner you’re bringing closer.
At Intervala, our electronic manufacturing services span the full product lifecycle—from design engineering and new product introduction (NPI) through high-mix, high-complexity PCBA, cable and harness assembly, electromechanical integration, and full system build and test. Our teams are organized by market vertical, which means the engineers supporting your aerospace program aren’t generalists. They understand your qualification requirements, your documentation standards, and your program timeline.
For OEMs evaluating a nearshore transition, here’s what that engagement typically looks like:
- NPI and transition support: We work alongside your engineering team during the new product introduction phase to optimize designs for manufacturability, reduce first-pass yield risk, and accelerate the path from prototype to production.
- Supply chain partnership: Our supply chain management capabilities include component lifecycle engineering, proactive obsolescence management, and sourcing strategies designed to reduce single-source risk.
- Engineering test services: Custom ICT, functional test, and environmental stress screening ensure product quality before it leaves our floor—not after it reaches yours.
- Scalable production: Whether you’re transitioning a single program or restructuring your full manufacturing footprint, we scale to match your volume and complexity requirements.
The Window Is Open—But It Won’t Stay That Way
The Bloomberg data makes a clear point: tariffs alone didn’t bring manufacturing back to North America—they moved it sideways. Companies that are genuinely building resilience are the ones making deliberate decisions about their manufacturing partners, not just their sourcing geography.
Qualified U.S.-based EMS capacity for high-complexity electronics is finite. The OEMs locking in manufacturing partnerships now—particularly in aerospace and defense and data center—are positioning for supply chain stability that their competitors will be chasing for years.
Nearshoring to a capable, technically deep EMS partner isn’t just a hedge against tariff volatility. It’s a structural improvement to your supply chain that pays dividends in speed, quality, and collaboration—regardless of what the next trade policy cycle brings.
