Indiscriminate tariffs aimed at reindustrialisation may undermine domestic efficiency and global competitiveness, and risk fueling inflation and harming small businesses and consumers
The United States has long been one of the strongest advocates of open markets and global supply chains. Behind this narrative, however, a steadily more activist trade stance has taken shape. In July 2025, the U.S. government issued letters of warning on tariffs to 14 countries—including Japan, South Korea, India, Brazil, and South Africa—with an effective tariff of 50 per cent on copper imports. This mass-action policy, justified on grounds of national security and reciprocity, represents a turning point in the American economic approach.
It appears that the logic now is not to lower tariffs to improve trading conditions, but rather to reindustrialise the national economy through protectionist measures. However, a closer examination reveals a deeper contradiction. Tariffs are imposed externally, yet their most lasting impacts are internal. In the case of copper—an essential input in construction, electric vehicles, and defence—a tariff-induced price shock reverberates across U.S. supply chains. The irony is clear: what is meant to boost self-reliance may actually create structural inefficiencies.
Classical trade theory—particularly the neoclassical growth model—holds that productivity thrives in environments of specialisation, comparative advantage, and capital mobility. Within such a framework, tariffs are viewed as distortions: they raise costs, waste resources, and reduce aggregate efficiency. Blanket tariffs on intermediate goods like copper, therefore, undermine competitiveness rather than enhance it.
This incongruity calls for a shift in analytical approach. Keynesian trade interventionism supports selective protection, particularly during strategic transitions. Tariffs, when applied indiscriminately and without regard to sectoral interdependencies or national capacity limitations, can be counterproductive. The U.S. imports over 800,000 metric tons of refined copper annually—roughly half of total demand. In such a scenario, a 50 per cent tariff functions less like a border tax and more like a domestic tax on production.
This cross-sectoral impact is significant. Companies that use copper—such as those in renewable energy, housing, and defence—now face higher input costs. The burden is not evenly distributed. Small and mid-sized firms, with tight margins and limited supplier flexibility, are the hardest hit. Meanwhile, Canada, which supplies nearly half of U.S. copper imports, has warned that these tariffs may harm U.S. manufacturing and inadvertently benefit Chinese processors. In trying to de-risk supply chains, the U.S. could be increasing global dependency.
Compounding this complexity is the executive-driven nature of U.S. tariff policy. The copper tariff has legal grounding under Section 232 of the Trade Expansion Act, while broader threats to the 14 targeted countries are based on Section 301. These laws give the executive branch sweeping authority, often bypassing congressional oversight. Such discretionary trade governance complicates business planning and foreign relations.
Copper is not alone. Proposed tariffs ranging from 25 to 40 per cent on products from the 14 targeted countries include pharmaceuticals, industrial goods, and consumer products. While the exact sectoral breakdown remains undisclosed, the broad scope suggests a shift from targeted protection to blanket economic pressure. Even offhand political remarks—such as those by former President Trump about imposing a 10 per cent group tariff on BRICS countries—reveal a geopolitical rather than economic motivation behind these policies.
It is precisely this indiscriminate approach that warrants caution. Tariffs imposed without consideration of industrial preparedness or sectoral context can lead to inefficient reshoring, inflation, and misallocated capital. These are not short-term transitional frictions but long-term inefficiencies that dull innovation and reduce competitiveness.
American households will not be shielded from the fallout. Traditionally, tariffs burden domestic consumers and importers. Low-income families, who spend a larger share of their income on goods rather than services, are especially vulnerable. If rising copper prices translate into higher housing, transport, and energy costs, the inflationary effects will cascade backwards.
This is not a call for passive liberalism. Strategic intervention can have its place, but it must be selective, transparent, and time-bound. Without such safeguards, protectionism becomes self-defeating.
American trade discourse is filled with talk of deficits, reshoring, and industrial revival. Yet it rarely addresses the quiet structural misalignments that tariffs—especially on critical inputs—can create. We are at a point where we must look beyond the optics of tariffs and take a harder, more honest view of their long-term domestic consequences.
A nation that taxes its own productive inputs under the guise of security must ensure it does not, in the process, strip itself of competitiveness. Misapplied tariffs may preserve the past, but at the cost of deferring the future.
