The Great Reshuffling of World Trade

A tax on imports, and on nearly every assumption the global economy had made about the United States.

A tariff is, at its most basic, a tax that a country charges on goods crossing its border. Every imported toaster, car part, bottle of olive oil, solar panel, and bag of coffee beans can carry one. For most of the post-war period, the United States kept its average tariff rate astonishingly low — a point of pride, a signal to allies, and a quiet subsidy to American consumers who grew accustomed to cheap everything. Then, in 2025, that arrangement was torn up.

By April 2026, after a year of escalations, counter-escalations, trade deals struck in hotel ballrooms, and a consequential Supreme Court ruling, the American tariff landscape looks nothing like what it did on Inauguration Day 2025. The average effective tariff rate sits at roughly 13.7% — still the highest since 1946, excluding the peak months of 2025 when it briefly hit 27%. Some countries pay a baseline of 10%. Others pay 35%, 50%, or, on very specific products, a triple-digit multiple of the item's value. The rules change by country, by product, by whether a component was forged in Ohio or Osaka, and sometimes by whether a president posted something on social media the night before.

This page is an attempt to make the whole thing legible. It is long — nearly nine thousand words — because the subject demands it. But it is also built to be explored: scroll for the narrative, click any country to see which of its exports are hit hardest, run the calculator to see what a $50 pair of sneakers from Vietnam actually costs an importer today, and watch the animated flow diagram below to see, step by step, how a tariff ripples from a port in Long Beach to a price tag at a hardware store in Des Moines.

Four tariff "buckets" you need to understand

Almost every import into the United States today passes through a stacking logic of up to four different legal authorities. They overlap, sometimes contradict, and are frequently the subject of litigation. But together they produce the sticker price an importer actually pays. In rough order of age:

The MFN schedule, or "Most Favored Nation" rates, is the baseline tariff chart the United States has maintained for decades under its World Trade Organization commitments. Most MFN rates are low — a few percentage points at most, many items at zero. This is the scaffolding on top of which everything else now sits. Before 2025, for most products from most trading partners, the MFN rate was the whole story. Today it is merely the floor.

Section 301 tariffs date back to the 1974 Trade Act and allow the president, through the US Trade Representative, to retaliate against foreign trade practices deemed unfair. The first Trump administration pioneered their aggressive modern use against China starting in 2018. The second Trump administration has kept almost all of those earlier 301 tariffs in place and, as of March 2026, has opened seventy-six new 301 investigations — against countries ranging from Algeria to Vietnam — that may serve as the legal basis for yet another wave of country-specific duties later this year.

Section 232 tariffs come from the 1962 Trade Expansion Act and allow the president to impose duties when imports threaten national security. They have become the administration's workhorse after the Supreme Court invalidated the so-called "reciprocal" tariffs in February. Section 232 is the legal scaffolding behind the 50% duty on imported steel and aluminum, the 25% duty on finished automobiles and auto parts, the new pharmaceutical tariffs of up to 100% on patented drugs, and targeted duties on copper, lumber, semiconductors, large batteries, and kitchen cabinets.

Section 122 tariffs are the newest addition to the toolbox and the most constitutionally fragile. After the Supreme Court struck down the IEEPA-based "reciprocal" tariffs on February 20, 2026, the administration turned to Section 122 of the 1974 Trade Act — a provision never previously used to impose broad tariffs — to levy a 10% duty on nearly every imported good. The statute says these tariffs can last no longer than 150 days, which means the Section 122 surcharge, as currently structured, is scheduled to expire on July 24, 2026. What replaces it is one of the central open questions of the year.

Tariff is the most beautiful word in the dictionary. — Donald J. Trump, campaign speech, 2024

These four layers stack. A shipment of steel from Brazil, for example, faces the MFN rate, plus the 50% Section 232 steel tariff, plus the 10% Section 122 baseline, plus any Section 301 penalty that might apply. An importer does not get to pick the lowest; all applicable layers apply at the same time. This "tariff stacking" is the reason headline numbers can mislead. A 10% base tariff sounds modest until you realize it is almost never the final number for anything that actually trips the statute.

The simple answer is "not the exporter." The honest answer is messier.

Economists have studied pass-through rates — how much of a tariff ends up in consumer prices versus absorbed by importers, retailers, or squeezed out of exporters — for a century. The conclusion from the 2018 and 2019 Trump tariffs, replicated across dozens of peer-reviewed studies, was that nearly the entire cost of those duties was passed through to American buyers within six to twelve months. The 2025–2026 round is larger, broader, and faster, but early evidence suggests the same pattern holds, with some nuances.

Three forces are at work simultaneously. The first is the direct pass-through: when an importer pays a 25% tariff on a shipment of auto parts, most of that ends up on the invoice to the retailer, who passes most of it to the consumer. Retailers with thin margins — hardware stores, big-box retailers, independent boutiques — have almost no cushion to absorb the added cost. Big brands with fat margins and pricing power can sometimes eat a portion, but they rarely eat all of it for long.

The second force is supply-chain rerouting. When Vietnam becomes cheaper than China, orders move to Vietnam. When Mexico becomes cheaper than Malaysia, orders move to Mexico. This shift takes time — factories have to be built, contracts rewritten, quality verified — but it is already visible in the trade data. US imports from China have fallen sharply, while imports from Vietnam, Mexico, and India have jumped. This rerouting is one of the stated policy goals, but it comes with costs: new supply chains are more expensive than mature ones, and products get more expensive during the transition.

The third force is retaliation. Trading partners impose counter-tariffs on US exports, which harms American farmers, manufacturers, and service exporters. China's retaliatory tariffs hit US soybeans, corn, and pork particularly hard. The EU has targeted American motorcycles, whiskey, and jeans. Canada has gone after American dairy, aluminum ingots, and consumer goods with surgical precision. The federal government has responded with farmer bailouts — a partial mitigation that does not, in the end, recover the lost export markets.

Tariffs are borders made of arithmetic.

The regressive arithmetic

Tariffs function as a consumption tax, and consumption taxes are regressive — lower-income households spend a higher share of their earnings on goods, particularly on imported staples, so they bear a disproportionate share of the burden. The Yale Budget Lab estimates that the 2026 tariff structure, post-SCOTUS, raises the average federal tax rate on the bottom quintile of households by 0.9 percentage points, compared to 0.7 points for the top quintile. In dollar terms, this translates to an average household cost of roughly $800 per year, with lower-income families paying around $400 on smaller incomes — a larger slice of their budgets.

The categories hit hardest are not luxuries. They are clothing, footwear, small appliances, electronics, furniture, and food — the weekly shopping list. A ten-pack of children's cotton undershirts that retailed at $12 in 2024 now retails near $16 at most big-box stores, and the difference is almost exactly the duty plus retail markup on the duty. A refrigerator that cost $900 now costs closer to $1,100. The ripple is subtle per-item and enormous in aggregate.

Which things on your shelf got more expensive, and why.

Not every imported good is tariffed equally. Some categories — the strategic or politically sensitive ones — carry surcharges that dwarf the baseline rate. Others escape almost untouched thanks to a trade agreement or a lucky exemption. Click a product tile to see the details.

Sectors that barely noticed

A handful of categories were explicitly exempted or negotiated down to zero. The United Kingdom, for example, secured a 0% tariff on pharmaceutical and medical technology exports in December 2025 in exchange for expanded US investment commitments and a significant increase in NHS spending on new treatments. Books, most raw data services, and certain strategic minerals remain untouched. A long list of energy-related products was carved out of the reciprocal framework when it was first announced in April 2025, and those carve-outs have largely persisted through subsequent rounds.

Sectors hit hardest

At the opposite extreme are patented pharmaceuticals without a bilateral carve-out, where the April 2026 Section 232 order permits duties of up to 100%. Chinese-origin advanced semiconductors — the Nvidia H200, the AMD MI325X, and related chips — carry a 25% surcharge on top of existing 301 duties. Chinese-origin electric vehicles face stacked duties that can exceed 100%. Ship-to-shore cranes and maritime cargo handling equipment from China carry 100% Section 301 duties as of October 2025. Solar cells imported from Indian, Indonesian, or Laotian companies face Commerce Department countervailing tariffs that, in some cases, reach triple digits. The list goes on: kitchen cabinets and bathroom vanities (25%), upholstered furniture (25%), large trucks, and a growing list of "derivatives" — products that contain tariffed inputs and therefore inherit some of the duty themselves.

Fourteen months, one tariff regime rebuilt twice.

A selective timeline of the moments that shaped the current system, from the opening salvos of early 2025 through the Supreme Court decision that re-wrote the legal basis in February 2026.

The legal scaffolding will decide what the next regime looks like.

The Section 122 tariffs face two pending lawsuits in the Court of International Trade — Oregon v. Trump and Burlap & Barrel, Inc. v. Trump — that could invalidate them before the statute's natural expiration in July. Oral arguments were heard on April 10, 2026, and the court's previous IEEPA ruling came down fifteen days after oral argument. A ruling is therefore possible any day now.

If the court strikes Section 122 too, the administration will have exhausted its two broadest tariff tools and will be left with Section 232 (product-specific), Section 301 (country-specific, with a lengthy administrative process), and the MFN baseline. That would push the tariff regime toward a more conventional, product-by-product approach — which is, ironically, closer to what most trade economists have long recommended. It would also remove the legal basis for the universal 10% baseline, cutting US revenues and reducing the negotiating leverage the administration has used to extract bilateral deals.

The other scenario is that the courts uphold Section 122 but the tariffs expire anyway in late July. In that case, the administration will almost certainly attempt to reimpose country-specific duties using the 76 new Section 301 investigations as the legal foundation. Section 301 has a well-established procedure — public comment, hearings, determinations of foreign unfair practices — and can support substantial tariffs, but it requires more process and produces country-by-country findings rather than a blanket rate. The resulting regime would look less like "10% everywhere" and more like "18% on Malaysia, 22% on Thailand, 29% on Vietnam, different rates on every major partner," with the specific numbers keyed to the specific findings of unfair practices.

Inflation, growth, and the Fed

The Yale Budget Lab estimates that the current, post-SCOTUS tariff structure raises the price level by roughly 0.6% in the short run and 0.5% in the long run after consumers substitute away from tariffed goods. The Peterson Institute's tracking pegs the average household cost at around $1,230 per year. The Tax Foundation's estimates are larger, at roughly $1,500 per household in 2026. All three estimates are considerably smaller than they were a year ago, because the IEEPA invalidation removed the largest single chunk of the tariff architecture.

For the Federal Reserve, the tariffs present a familiar but frustrating problem: a supply-side price shock that is essentially a one-time level increase in the price of imported goods rather than a sustained increase in the rate of inflation. Economists generally advise central banks to look through such shocks, because tightening monetary policy in response would aggravate the real-income loss without removing the underlying price increase. The Fed has largely followed that playbook, holding rates roughly steady through the tariff turbulence. The risk is that tariff-driven inflation becomes embedded in wage and price-setting expectations — a risk that rises the longer high tariffs stay in place and the more waves of new duties arrive.

The geopolitics of the new system

The tariff regime has reshaped America's economic relationships in ways that will outlast any particular legal ruling. Canada, long the closest US trading partner, has seen the largest hit to output of any major economy from the remaining tariffs, according to Yale's Budget Lab modeling. Mexico's economy is modestly smaller. China's economy is meaningfully smaller than in a counterfactual without 2018–2026 tariffs, though the effect is blunted by China's aggressive supply-chain rerouting through Southeast Asia. The UK, EU, and Japan all see small long-run gains — a surprising result explained by the fact that all three secured deal rates well below the global maximum and are now benefiting, relatively, from tariffs imposed on their competitors.

A harder-to-quantify effect is the erosion of the United States' reliability as a trading partner. The last fourteen months have seen deals struck, renegotiated, threatened, extended, and occasionally reversed within a single news cycle. Companies that depend on stable trade relationships — automakers, electronics manufacturers, pharmaceutical makers, retailers — now bake a "Trump risk premium" into every long-term capital expenditure. That premium shows up as higher prices, delayed investments, and a subtle but real preference for suppliers inside jurisdictions where policy is considered more predictable. Whether that is Mexico under USMCA, Vietnam after its deal, or the European single market depends on the company and the product. It is no longer, reliably, the United States itself.

Plain answers to plain questions.

The only thing harder than a tariff is a tariff you didn't see coming.

Trade policy is, in the end, a theory of who belongs in the economy.

Every tariff decision answers a set of questions the decider may not have consciously asked: Which workers are worth protecting, and from what? Which consumers are worth protecting, and from whom? Which alliances matter more than which prices? Which industries are strategic, and which are sentimental? Which harms are visible, tolerable, distributed — and which are invisible, concentrated, politically cheap?

The Trump tariff regime of 2025–2026 is best understood not as a single policy but as an ongoing argument — conducted through executive orders, Supreme Court decisions, foreign retaliation, and everyday price tags — about those underlying questions. It is an argument the country has had before, most intensely during the Smoot-Hawley era of the 1930s, and one it will continue to have regardless of who sits in the Oval Office next. The instruments, and their names, will keep changing. The underlying question — who belongs, who pays, who is protected — will not.
