In early 2025, a seemingly straightforward policy decision created an unexpected gridlock: requiring EV chargers to be built entirely in the United States with American-made components effectively froze billions in federal charging infrastructure funding. Even after courts ordered the funds released, the technical reality remained—building complex technology products with purely domestic supply chains isn’t just difficult, it’s often technically impossible with current infrastructure.
This isn’t about politics or economics alone. It’s about understanding how modern technology manufacturing actually works, and why the world’s supply chains have evolved into the intricate web they are today.
The Global Assembly Line
Let’s start with a seemingly simple product: an electric vehicle charging station.
You might think of it as a single piece of equipment, but it’s actually an orchestra of components. Inside that box on the wall, you’ll find circuit boards, semiconductors, power management systems, cooling components, display screens, networking equipment, cables with specialized connectors, and safety systems. Each of these components contains sub-components, which contain their own materials and parts.
Here’s where it gets interesting: nearly every one of these components comes from a different place, made by companies that specialize in that specific technology. The power management chips might come from a fab in Taiwan. The rare earth magnets in transformers likely originated in China, which controls about 70% of global rare earth mining and 90% of processing. The specialized high-grade copper for conductors might be refined in Chile. The glass for displays could be from Japan. The software running the system was probably developed across multiple countries.
This isn’t inefficiency—it’s specialization at a global scale.
Why Geography Matters in Manufacturing
Manufacturing isn’t just about having the right equipment and raw materials. It’s about expertise, infrastructure, and what economists call “learning curves.”
Consider semiconductor manufacturing, one of the most complex processes humans have invented. Taiwan Semiconductor Manufacturing Company (TSMC) can produce chips at 3-nanometer scale with yields (the percentage of working chips) above 80%. When they built new fabs in Arizona, they faced unexpected challenges: different humidity levels affect chemical processes, local building practices differed from Taiwan’s standards, and critically, the deep pool of experienced engineers who understand the thousand subtle variables in chip production wasn’t there.
It takes years—sometimes decades—to build this kind of manufacturing expertise. Engineers learn through experience. Supply networks develop relationships. Quality control processes get refined through millions of iterations. You can’t simply copy the equipment and expect the same results.
The Depth of Supply Chains
Let’s trace a single component backward through the supply chain.
Take a simple circuit board. To make it, you need:
The board itself: Made from fiberglass and copper. The fiberglass cloth might come from one country, the epoxy resin from another. The copper is refined somewhere else, and the lamination happens in yet another facility.
The components soldered to it: Resistors, capacitors, chips, connectors. Each manufactured in specialized facilities. A modern smartphone circuit board might have 200+ distinct components from 30+ different suppliers.
The equipment to assemble it: Pick-and-place machines cost millions and are made by only a handful of companies worldwide. The specialized solder paste, the reflow ovens, the automated optical inspection systems—each has its own supply chain.
The materials in those components: The ceramic for capacitors requires specific clays. Semiconductor chips need ultra-pure silicon, dozens of rare gases, and chemical photoresists. Some of these materials are only produced at scale in a single location globally.
This is what supply chain professionals call “supply chain depth”—components made from sub-components, made from materials, made from raw materials, each with their own geographic concentration.
The Restaurant Analogy: Why Pure Local Sourcing Breaks Down
Imagine you want to open a restaurant that only uses local ingredients and equipment—everything must come from within 50 miles.
Initially, this sounds wonderful. Support local farmers, local businesses, local economy. But then reality sets in:
Your industrial oven? No one manufactures those locally. Okay, you think, we’ll make one. But that requires specialized steel, insulation materials, thermostats, and gas burners or heating elements. None of those are made locally either. You’d need to build factories to make the components, then factories to make the equipment for those factories.
Want to serve coffee? Coffee doesn’t grow in most climates. Spices? Same issue. Even basic items like stainless steel pots require materials and manufacturing processes not available locally.
The reality is that your “local only” restaurant would be limited to whatever can be grown, raised, or caught within 50 miles, cooked with wood fire or locally-made solar ovens, served on handmade pottery (if local clay is available).
Technology supply chains face exactly this problem, but amplified by orders of magnitude in complexity.
The Economic Geography of Manufacturing
Certain places became manufacturing hubs not by accident, but through decades of infrastructure development, education systems, business networks, and institutional knowledge.
Taiwan’s semiconductor dominance came from government investment in the 1980s, a culture of engineering excellence, universities producing thousands of trained engineers annually, and aggressive investment in staying at the cutting edge. Other countries have spent billions trying to replicate this and found it takes decades to build the ecosystem.
China’s rare earth processing monopoly emerged because processing these materials is environmentally challenging, requires specific expertise, and benefits enormously from scale. Other countries have rare earth deposits but lack the processing infrastructure and knowledge.
Germany’s precision manufacturing reputation was built over a century through apprenticeship systems, engineering education, and companies that stayed focused on specific niches for generations.
Silicon Valley’s software expertise concentrated through network effects—talented engineers want to work where other talented engineers are, companies locate where the talent is, universities adapt to supply the local industry.
This geographic concentration of expertise and infrastructure isn’t easily relocated.
What Happens When You Force Local Production
When regulations require domestic content without considering supply chain realities, several things happen:
Projects halt entirely: If components literally don’t exist domestically and can’t be made quickly, projects stop. This is what happened with the EV charger infrastructure program—manufacturers couldn’t comply because the domestic supply chain doesn’t yet exist.
Costs explode: Building new supply chains from scratch requires massive investment. Small-scale production costs far more than large-scale production. These costs get passed to consumers or make projects economically unviable.
Quality suffers: New production facilities lack the years of refinement that established manufacturers have. Yields are lower, defects are higher, and reliability decreases until expertise develops.
Innovation slows: Engineers at cutting-edge facilities constantly push technology forward. New facilities start years behind and must catch up before innovating.
Cascading effects: When one component can’t be sourced, entire product lines fail. A missing $2 chip can halt production of a $50,000 vehicle.
The Technical Barriers Are Real
Some barriers to domestic production are particularly challenging:
Patent and licensing issues: Critical technologies are often patented internationally. Even if you build the equipment, you may not have the legal right to use certain processes.
Equipment bottlenecks: Some manufacturing equipment is made by only one or two companies globally. They can’t scale production instantly. The machines themselves can take years to build and cost tens of millions.
Materials science: Certain materials require specific conditions to produce. You can’t make them in just any factory. The equipment, expertise, and input materials must all align.
Critical mass: Many processes only work economically at large scale. A factory producing a million units can achieve quality and cost points impossible at smaller scale. Starting from zero means years of losses.
Tacit knowledge: Much manufacturing expertise isn’t written down—it’s in the heads of experienced engineers and technicians who learned through years of troubleshooting. This knowledge doesn’t transfer easily.
What Realistic Domestic Manufacturing Looks Like
This doesn’t mean domestic manufacturing is impossible—it means it requires realistic timelines and expectations.
Strategic focus: Rather than trying to make everything domestically, focus on critical components where supply security matters most. Not every component needs to be made locally.
Long-term investment: Building supply chains takes 5-10 years minimum for complex technologies. Policies need to support this timeline, not expect instant results.
Partial domestic content: Set realistic domestic content targets that increase over time as capabilities develop. The EU’s approach to battery manufacturing, for example, sets graduated targets over a decade.
Infrastructure development: Invest in the underlying infrastructure—trained workforce, research facilities, equipment manufacturers, materials processing—not just final assembly.
Alliance networks: Work with allied nations to build resilient supply chains that aren’t dependent on potential adversaries, but don’t require everything to come from a single country.
The Semiconductor Case Study
The CHIPS Act in the United States allocated $52 billion to rebuild domestic semiconductor manufacturing. This is instructive because it acknowledges the reality of supply chain complexity.
The funding supports:
- Building new fabrication facilities (5+ years to construct and ramp up)
- Training programs for thousands of engineers and technicians
- Research into new manufacturing processes
- Supporting equipment manufacturers and materials suppliers
- Creating networks of related industries
Even with massive investment, realistic projections suggest it will take until the 2030s to significantly reduce dependence on foreign chip manufacturing. And even then, many components of the supply chain will remain global.
This is what realistic reshoring looks like: long timelines, massive investment, strategic focus, and acknowledgment that complete self-sufficiency isn’t the goal.
Why This Matters Beyond Policy
Understanding supply chain reality matters for everyone:
As consumers: When you see price increases for electronics, vehicles, or other products, supply chain constraints are often the cause. Understanding this helps you evaluate whether prices are justified.
As workers: Manufacturing jobs can return, but they’ll be different than the assembly-line jobs of the past. Modern manufacturing requires technical skills and training.
As citizens: Evaluating policy proposals requires understanding what’s technically feasible. A policy that sounds good but can’t work in practice helps no one.
As businesses: Companies must plan for supply chain resilience while remaining cost-competitive. This means diversification, inventory strategies, and relationship building with suppliers.
As a society: We face genuine tensions between resilience (wanting domestic capability), efficiency (global specialization saves money), and security (not depending on potential adversaries). There are no perfect answers, only trade-offs.
The Path Forward
The future of manufacturing isn’t a simple choice between “make everything here” or “make everything abroad.” It’s about building intelligent, resilient supply chains that balance multiple goals:
Critical capabilities: Ensure domestic capacity for truly critical technologies—defense, healthcare, energy infrastructure—even if it costs more.
Allied networks: Build supply chains with trusted partners, creating redundancy without requiring every country to make everything.
Gradual development: Support long-term development of manufacturing capabilities with realistic timelines and sustained investment.
Innovation focus: Invest in next-generation technologies where the playing field is more level, rather than only trying to replicate existing foreign capabilities.
Flexibility: Design products and policies with supply chain flexibility in mind, avoiding single points of failure.
Conclusion
The lesson from frozen EV charging infrastructure, semiconductor supply constraints, and countless other examples isn’t that domestic manufacturing is impossible—it’s that it’s hard, requires time and investment, and can’t be mandated into existence overnight.
Modern technology products are marvels of global coordination. Thousands of companies across dozens of countries collaborate to create the devices we use daily. This system evolved because it’s remarkably efficient at delivering complex products at reasonable costs.
Building alternatives to this system isn’t impossible, but it requires acknowledging the technical realities: the depth of supply chains, the geographic concentration of expertise, the time required to build manufacturing capability, and the economic challenges of starting from scratch.
The next time you hear about “Buy American” or other domestic content requirements, you’ll understand why the conversation is more complex than it first appears. It’s not just about economic policy or political will—it’s about the fundamental technical realities of how modern technology is made.
And that understanding is the first step toward building policies that can actually work.
