The Tariff Paradox: Mexico and Brazil Raised Their Walls, and Chinese Cars Kept Coming

by Francis Rozange | Sep 28, 2026 | 0 comments

On the first day of 2026, the duty Mexico charges on a passenger car built in a country with which it has no trade agreement jumped from 20 percent to 50 percent. China was the obvious target. Its customs statistics registered the blow within weeks: exports of Chinese cars to Mexico fell to about $188 million in January, down 45.3 percent from a year earlier and 82.3 percent below the $1.06 billion shipped in November 2025, when Mexico had briefly been the largest buyer of Chinese cars in the world. By any customs-house measure, the wall worked. And yet, eight months later, Mexico’s association of car dealers estimated that brands of purely Chinese origin held about 17 percent of the country’s new-vehicle market, while those that report to INEGI had gained share over the year.

Brazil ran a slower version of the same experiment. Under a schedule set in late 2023, its import tax on fully built electric cars climbed step by step until it reached 35 percent in July 2026. In August, the largest Chinese maker of electrified cars registered more than twice as many cars and light commercial vehicles in Brazil as it had a year earlier, and electric-car registrations in the country more than tripled. Two large Latin American governments raised tariffs; in both, Chinese brands kept gaining share. The explanation is not that tariffs fail. It is that a tariff acts on a border, while a market share is decided in a showroom, and between the two lie inventory, arithmetic, factories and buyers.

A Wall Built One Tariff Line at a Time

The Mexican measure is a decree amending the country’s general import tariff law, approved by Congress on 10 December 2025, signed by President Claudia Sheinbaum on 23 December and published in the Diario Oficial de la Federación on 29 December. Its first transitory article sets the start date at 1 January 2026. The decree’s schedule lists the residual passenger-car headings for gasoline, diesel, hybrid and plug-in hybrid vehicles at 50 percent, and it does the same for tariff line 8703.80.01, electric cars “except used.” Light trucks receive the same treatment. Parts were not spared: complete bumpers designed for cars carrying up to ten people, for example, are listed at 25 percent.

Because these are general rates, they fall on any country without a free trade agreement in force with Mexico, which puts China in the same category as India, South Korea and several others. A fourth transitory article leaves the Secretaría de Economía room to create specific mechanisms for imports from such countries when needed to keep Mexican industry supplied on competitive terms. The government presented the package as a defense of domestic industry and jobs, according to an English-language Mexican news site. China’s Ministry of Commerce, quoted by a logistics trade publication, urged Mexico to “rectify this erroneous approach rooted in unilateralism and protectionism.” The legal architecture matters for what follows: the duty is levied on where a vehicle was built, not on who owns the brand.

The Rush Before the Gate Closed

The months before the decree took effect produced the most revealing data of the whole episode. Figures from China’s General Administration of Customs, relayed by the Mexican press, show Chinese car exports to Mexico worth about $6.35 billion in 2025, against $4.38 billion in 2024. In November 2025 alone, weeks before Congress approved the new rates, the figure reached $1.06 billion. By January, Mexico had fallen to sixteenth place among the destinations for Chinese cars, and a trade publication citing the same customs source put the combined January and February 2026 total at $399 million, down 53.5 percent from the first two months of 2025.

Unit counts point the same way. The China Passenger Car Association, as cited by a Mexican motoring outlet, counted 625,187 vehicles exported to Mexico in 2025, making Mexico the top destination for Chinese vehicles that year. The same outlet compared that total with sales recorded by INEGI, Mexico’s statistics institute, plus its own estimates for brands that do not report, and concluded that roughly 218,000 of those vehicles had been imported but not yet sold when the year closed. That is a press estimate, not an official inventory count. But its direction is consistent with every other source: a large volume of Chinese-built stock crossed the border at the old 20 percent rate.

Showrooms That Barely Noticed

INEGI’s registry of light-vehicle sales shows a Mexican market that set a record in the first eight months of 2026: 1,014,715 new light vehicles, 4.7 percent more than a year earlier, the highest January to August total in the published series, according to the dealers’ association AMDA. Within that total, a large Hangzhou-based group sold 31,606 vehicles, up 200.6 percent. A British-heritage marque owned by a Shanghai state group sold 36,019, up 13 percent, and a Chongqing-based state carmaker sold 14,418, up 30.9 percent. Adding up the nine Chinese-owned brands that report to INEGI gives 114,613 units, about 11.3 percent of the market; AMDA, which counts one more Chinese brand sold inside a European group, puts the figure at 11.4 percent.

The gains were not universal, and the exceptions are instructive. A Baoding-based maker of SUVs and pickups slipped 8.8 percent in INEGI’s count, and a Chinese light-truck and SUV maker assembled in Mexico fell 5.2 percent. An importer that aggregates four smaller Chinese brands saw its reported sales collapse and did not file August figures at all. Most striking, the largest Chinese maker of electrified cars, which does not report to INEGI, was estimated by AMDA at 45,296 units for January to August, 4.0 percent below the same period of 2025, and at 5,327 in August against 6,045 a year earlier. The paradox belongs to the Chinese brands as a group. Individual companies have fared very differently behind the same wall.

What “Number Two Supplier” Really Measures

In August a Mexican business news site reported that China had become Mexico’s second-largest supplier of light vehicles in the first half of 2026, with about 22 percent of vehicles sold, behind the 32.3 percent built in Mexico itself. The figure is consistent with AMDA’s data, but it measures country of manufacture, not the nationality of the brand. AMDA’s own tabulation of INEGI data for January to August puts the share of domestic sales made up of China-built vehicles at 22.8 percent among reporting brands, and at about 28 percent once estimates for non-reporting brands are added. That is double the 11.4 percent held by the reporting Chinese brands.

The difference is made up largely of companies that are not Chinese at all. AMDA’s origin tables show that an American carmaker with deep roots in Detroit sold 92,522 China-built vehicles in Mexico between January and August, 14.8 percent more than a year earlier and 71 percent of its Mexican sales. Another Detroit company sold 12,156 China-built vehicles, up 46.3 percent. A South Korean brand sold 17,489 units made in China, and a transatlantic group’s American brands 7,625. All of these vehicles pay the same 50 percent duty as a Chinese brand’s. Mexico’s wall taxes Chinese factories, many of which build for Western and Asian brands.

Inventory as a Temporary Shield

The first and simplest reason showrooms did not empty is that much of what they sold in 2026 had already cleared customs. Mexican Economy Ministry data, reported from late August by several national outlets, show light-vehicle imports from China of 158,571 units in the first half of 2026, down 31.1 percent from 230,033 a year earlier, and a value of $2.159 billion, down 35.4 percent. Imports of light vehicles from all countries without a trade agreement fell 24.1 percent, to 247,963 units. Yet AMDA’s chart of sales by origin shows China-built vehicles sold in Mexico up about 20 percent over January to August. When imports fall by nearly a third while sales rise by a fifth, the most plausible source of the difference is stock imported earlier.

Guillermo Rosales Zárate, AMDA’s executive president, said as much at the end of August. “In the remaining months, with the reduction of inventories, new shipments will already carry the impact of the tariff increase, and with it an increase in the final price to the consumer will begin to show,” he said, adding that “so far this has not happened” and that retail prices of Chinese cars had not varied significantly. He attributed the stability to cost absorption by manufacturers and distributors and a favorable exchange rate. That statement, from the dealers who actually set transaction prices, is the most direct evidence available that the 50 percent duty had not yet reached the sticker by late summer. It also marks the paradox as partly a matter of timing.

The Arithmetic of a Landed Car

Inventory explains a lag, not a trend. The second reason lies in what a tariff increase actually does to the cost of a vehicle once it reaches the lot. A duty is charged on customs value, which for a mass-market car is well below the retail price. Moving from 20 to 50 percent raises the landed cost of the vehicle, duty included, by a quarter: a car that cost 1.2 times its declared value to land now costs 1.5 times. In Mexico, value-added tax on imports is calculated on a base that includes the duty, which widens the gap further. But they are applied to a factory price set by the exporter, and an exporter with low production costs and strategic reasons to hold share can lower that price.

Manufacturers do not publish their export margins, so the size of any absorption is unknown. What can be said is that the capacity exists and that some companies have attacked other layers of cost. A Mexican motoring outlet reported in September that the largest Chinese electrified carmaker’s own fleet of car carriers cuts its shipping costs by 30 to 40 percent compared with using outside operators; that is a press report of a company practice, not an audited figure. A 50 percent duty is a large number in a legal text and a smaller one in a showroom, because it is levied on the least visible part of the price and because the party paying it can choose, within limits, how much to pass on.

Assembly Inside the Wall

The third answer is to stop importing finished cars. One Chinese light-truck and SUV maker has done this for years in the state of Hidalgo, where a Mexican partner company assembles its vehicles from semi-knocked-down kits. According to a Mexican business magazine, the plant employs about 900 people, has a capacity of 60,000 units after 3 billion pesos of investment, and its output is treated as Mexican-made rather than as an imported finished vehicle. INEGI’s data show it produced 16,792 vehicles between January and August 2026, 14.1 percent fewer than a year earlier, and sold 15,371 in Mexico. A Chinese truck maker began reporting Mexican production to INEGI in September, with 1,379 units for the first eight months of 2026.

A larger local footprint has been discussed but not delivered. After a joint plant in Aguascalientes owned by a Japanese carmaker and a German luxury group announced its closure, a news agency reported in February, according to Mexican press accounts, that at least eleven parties were interested, with the largest Chinese electrified carmaker and the Hangzhou-based group as the main options. The plant closed on 31 May 2026. As of early August, a local newspaper reported, it still had no buyer. A Mexican business magazine had earlier quoted an industry consultant saying that no investment announcement was likely until the terms of the upcoming review of the United States, Mexico and Canada trade agreement were clear.

A Market Share Won With Less Credit

In most markets, the fastest way to move cars is cheap financing, and it is here that Mexico’s data hold their least expected finding. According to AMDA figures reported by a Mexican business daily, the share of Chinese-brand sales bought with credit fell to 58.5 percent in January to July 2026, from 71.1 percent a year earlier, even as their sales grew. For the market as a whole, AMDA put retail financing penetration at 75.3 percent. Its own July report, based on data from an automotive data firm, shows carmakers’ captive finance companies providing 79.58 percent of all credit for new vehicles. Chinese brands, Mr. Rosales told another newspaper, “currently lack a financial arm in the country” and sell through alliances with banks.

The incumbents have understood where their advantage lies. The director of that same data firm told the business daily that established carmakers had deployed “unusual aggressiveness,” offering zero-interest loans over terms of up to 60 months, which he described as unsustainable. Read together, these figures suggest, as analysis rather than proof, that Chinese brands in Mexico are winning buyers on price and equipment rather than on financing, and that the traditional carmakers are answering with the one weapon the newcomers do not yet control. The tariff rewards the brand that can protect its sticker price longest while its rivals subsidize credit.

Brazil’s Slower, Longer Staircase

Brazil’s wall was designed differently. In November 2023 the government’s foreign trade executive committee, Gecex, restored import duties on electrified cars that had been zero, on a published schedule reported by the federal government’s own news agency. For battery-electric cars the rate was 10 percent in January 2024, 18 percent in July 2024, 25 percent in July 2025 and 35 percent in July 2026. Hybrids followed a 12, 25, 30 and 35 percent path, and plug-in hybrids 12, 20, 28 and 35 percent, over the same dates. Shrinking duty-free quotas eased the transition: for electric cars, $283 million in the first period, then $226 million, then $141 million.

The market into which those tariffs landed has been buoyant. Fenabrave, the national federation of vehicle distributors, reported 263,054 cars and light commercial vehicles registered in August 2026, 22.67 percent more than in August 2025; with trucks and buses, the total reached 275,094, up 22.10 percent. Over January to August, car and light commercial registrations rose 19.78 percent, to 1,887,750, even though, as Fenabrave noted, the benchmark Selic interest rate still stood at 14 percent in August. In a market growing that fast, rising share is harder to achieve than rising volume, which makes the Chinese numbers all the more notable.

The Registrations Behind the Headline

Fenabrave’s brand tables are unambiguous. The largest Chinese electrified carmaker registered 24,467 cars and light commercials in August 2026, a 9.30 percent share, against 9,815 and 4.58 percent in August 2025; in passenger cars alone it ranked third, with 11.47 percent. The Baoding-based SUV and pickup maker went from 3,924 to 9,825. The Hangzhou-based group registered 7,524 in August, and a newer crossover label from a large Anhui-based group went from 720 to 5,902. The nine brands of Chinese origin that appear in Fenabrave’s top rankings for August totaled 59,629 units, about 22.7 percent of the car and light commercial market. A year earlier, the Chinese brands that cleared the ranking threshold totaled 21,748, about a tenth.

Electrification is where the Brazilian paradox is sharpest. Fenabrave counted 62,365 electrified passenger cars registered in August 2026, against 25,097 a year earlier, and 27,061 battery-electric cars against 7,578, an increase of 257 percent, in the very month after the 35 percent duty took effect. The largest Chinese electrified carmaker alone registered 16,077 electric cars, 59.4 percent of the segment, and the Hangzhou group 6,178. Over January to August, the leading brand’s registrations reached 146,930, against 67,185 a year earlier, lifting its share from 4.26 to 7.78 percent. Much of this volume no longer arrives as finished cars, which is the key to reading the Brazilian case.

Camaçari and the Politics of the Kit

The largest Chinese electrified carmaker’s plant in Camaçari, in the state of Bahia, began producing in 2025. In a January statement, the company said the site had built about 18,000 vehicles since its inauguration in October and planned to add welding, stamping and painting operations in 2026, described local production as its “principal differentiator” from competitors, and a senior vice-president said the plant’s output would be decisive for price competitiveness once import tariff incentives ended. A regional business outlet reported that the plant reached its 100,000th vehicle on 16 July 2026. At an investor event later that month, a company director described a first stage of 150,000 vehicles a year, rising later to 300,000 and 600,000. A Bahia newspaper reported a company target of 50 percent local content by the end of 2026. These are company statements and plans, not verified output.

The plant has so far worked mainly from imported kits, and the kits became the battleground. In July 2025, Gecex brought forward the date at which semi-knocked-down and completely knocked-down electrified kits would pay the full 35 percent, from July 2028 to January 2027, and opened a six-month duty-free quota of $463 million for such kits. That quota lapsed at the end of January 2026, according to a trade publication; the carmakers’ association Anfavea dates its end to February. Trade publications disagree on the rates that applied to kits outside the quota, citing figures between 14 and 18 percent, and by mid-2026 Brazilian press put semi-knocked-down kits at 35 percent and completely knocked-down kits at 14 percent. In June 2026, Gecex renewed the $463 million duty-free quota for six more months from 1 July.

An Industry Lobby Against a Moving Target

Anfavea, which represents the established carmakers, reacted sharply. In a statement on 23 June 2026 it said it received the decision “with great concern,” that the measure ran against the interests of workers, national vehicle manufacturers and Brazilian parts makers, and that by extending benefits created as temporary, the government “puts in check the confidence of companies that adjusted their plans.” A trade publication reported that the association’s president had raised the possibility of legal action. Anfavea also argued that its members had announced 140 billion reais of investment through 2033 and that locally produced vehicles accounted for 25.9 percent of electrified sales in 2025.

The dispute illustrates how differently Brazil’s wall behaves from Mexico’s. Mexico raised a single rate on finished cars and left assembly largely outside the debate. Brazil’s policy is a sequence of dated steps, quotas and exceptions, each renegotiated under pressure from both sides. For a Chinese manufacturer, that uncertainty is itself an incentive to move production onshore faster, because the only status that cannot be revised by the next Gecex meeting is that of a vehicle built in Brazil. For the incumbents, the result is a rival that is at once an importer, a kit assembler and, increasingly, a local manufacturer, with each role governed by a different rate.

A Tax Break That Rewards Stamping Presses

The decisive lever in Brazil may not be a tariff at all but the domestic industrial products tax, IPI. Decree 12.549 of 10 July 2025, issued under the law that created the Mover program for green mobility, set a base IPI rate of 6.3 percent for passenger cars, adjusted by bonuses and penalties for efficiency, safety and recyclability. It also created a “sustainable vehicle” category with an IPI rate of zero until 31 December 2026. To qualify, a vehicle must emit no more than 83 grams of carbon dioxide per kilometer measured from well to wheel, be at least 80 percent recyclable, belong to the subcompact, compact, compact SUV or compact pickup categories, and undergo in Brazil the stamping of exterior panels, welding, painting, engine manufacture and final assembly.

That list of manufacturing steps reads almost as a description of what a kit-assembly plant does not yet do. It explains, better than any tariff schedule, why the largest Chinese electrified carmaker has announced stamping, welding and painting halls in Camaçari, and why a Baoding-based rival converted a former German-owned plant in São Paulo state, acquired in 2021, which a trade publication reports opened in August 2025. In analytical terms, Brazil has built a funnel rather than a wall: tariffs and quotas make finished imports progressively dearer, while tax rules make genuine local manufacturing progressively more rewarding. Chinese brands are not evading that design. They are following it, at a speed the established carmakers did not expect.

A Southern Door Into Mexico

The two markets are linked by a trade agreement that rarely makes headlines. Under ACE 55, the automotive agreement between Mexico and the Mercosur countries, qualifying vehicles from Brazil, Argentina, Paraguay and Uruguay can enter Mexico with lower duties or none, as a logistics trade publication noted when Mexico’s new tariffs took effect. The route is already busy. AMDA’s origin tables show that in January to August 2026 a German group’s Mexican unit sold 21,653 Brazilian-built vehicles, a French brand 18,748, the Detroit carmaker 17,841 and the transatlantic group’s American brands 13,547. Vehicles that qualify under the agreement are spared the 50 percent rate reserved for countries without one.

In March 2026, the largest Chinese electrified carmaker’s executive vice-president said, according to a news agency report relayed by the Chinese press, that its Brazilian plant had secured export orders of 100,000 vehicles, half for Argentina and half for Mexico. In July, a company director spoke of demand for the same volumes, which a Bahia newspaper characterized as “orders or commercial prospects reported by the company” rather than confirmed contracts. Whether vehicles assembled from imported kits would satisfy the agreement’s rules of origin has not been publicly documented by the company or by the governments concerned. If they did, Mexico’s 50 percent duty on Chinese factories could be partly bypassed through a Brazilian factory owned by a Chinese company. That remains a possibility to monitor, not an established fact.

What Buyers Are Actually Choosing

Official statistics say a great deal about what was sold and very little about why. Behavior offers some clues. AMDA reported 129,359 hybrid and electric vehicles sold in Mexico in January to August 2026, up 46.1 percent and equal to 12.8 percent of the market. In Brazil, Chinese brands lead both the hybrid and the electric rankings. The fact that Chinese-brand buyers in Mexico financed fewer purchases while their numbers grew suggests a clientele that is not simply chasing easy monthly payments. But residual values, service satisfaction and repurchase intentions for Chinese brands are not published by INEGI, AMDA, Fenabrave or Anfavea.

That silence is where the most useful questions now sit. Whether a Mexican buyer who chose a Chinese SUV in 2025 would do so again at a higher price in 2027, whether a Brazilian family sees a locally assembled Chinese car differently from an imported one, and how dealers weigh a new franchise against an old one are matters for customer research and competitive research, the disciplines CSM International applies in its automotive research across markets where the official record ends at the registration count. Tariffs can be read in a decree and registrations in a monthly bulletin. Brand acceptance has to be measured, and it may be shaping market share as much as customs rates do, a hypothesis the official statistics cannot test.

When the Stock Runs Out

The coming months will test each explanation separately. In Mexico, the inventory cushion is finite by definition. AMDA expects new shipments at the higher duty to begin lifting prices; if they do, the monthly INEGI figures should show whether Chinese brands hold their volume at the new price, cede share, or shift their mix toward vehicles that are cheaper to land. August already offered mixed signals, with the Chongqing-based brand down 23.4 percent and the Hangzhou group still up 106.7 percent. The prospect of Brazilian sourcing, and the unresolved fate of the Aguascalientes plant, add two variables that no forecast can yet price.

In Brazil, the calendar is written down. Under the decisions reported so far, all electrified kits are due to pay 35 percent from January 2027, the current duty-free kit quota runs to the end of 2026, and the zero IPI rate for sustainable vehicles is set to expire on 31 December 2026 unless renewed. Two of them, the kit tariff date and the kit quota, have already moved at least once. What the record does show is that the Chinese manufacturer most exposed to these dates has announced stamping, welding and painting halls, and that the established carmakers are contesting the timetable rather than the principle of localization.

The Verdict Delivered at the Dealership

Seen from a customs office, Mexico and Brazil both did what they set out to do. Imports of finished Chinese cars into Mexico fell sharply after January, and Brazil’s tariff staircase reached its top step on schedule in July. Seen from a showroom, neither wall produced the retreat its advocates might have expected. In Mexico, Chinese brands held an estimated 17 percent of sales, helped by stock imported at the old rate, prices that had not moved, and a customer base less dependent on subsidized credit than their rivals’. In Brazil, they rose faster still, in part by doing what the policy encouraged: assembling, and increasingly building, cars inside the country.

A tariff changes the route a car takes to market: the factory it leaves, the ship it boards, the kit it arrives in, the partner who bolts it together. It changes the buyer’s decision only at the margin, and only once the cost reaches the price tag. The evidence from both countries suggests that the second step is slower and less certain than the first. The Chinese manufacturers appear to have learned something else: that a wall announced a year in advance is less an obstacle than a timetable, and that the most durable way through it is to end up on the other side.
