China front-loaded Mexico before the 50% car tariff. Then its mix changed.

On 1 January 2026 Mexico raised its import tariff on 1,463 tariff lines for countries it has no trade agreement with, at rates from 5% to 50%[1]. Goods that qualify under a trade agreement, such as USMCA, keep their preferential rate[2]. For passenger cars the new rate is 50%, up from 20% until 31 December 2025[3][4]. China was the obvious target. In January to August 2025 it supplied about half of all the cars that arrived in Mexico by sea.

We counted every car declared at Mexican customs on arrival by sea from October 2024 to August 2026, using the units on each customs line and the HS subheading to tell an electric car from a petrol one. Quad bikes, motor tricycles and golf carts share the same HS heading; we left them out. Nine months is enough to see what the tariff did to shipments. It isn’t enough to see where they settle.

The rush before 1 January

Between October and December 2025, 194,158 cars from China arrived in Mexico by sea, against 71,276 in the same quarter of 2024. December was the peak at 102,819, nearly three times the average month of 2025 before it. Plug-ins drove it. Battery-electric and plug-in hybrid cars from China came to 56,460 in December alone, more than half of that month’s cars and about five times the average month of January to November 2025 (10,996). Benchmark counted more than 50,000 electric cars and light vans imported into Mexico that month, a record[5]. The two counts are close.

Dealers expected this. In May, the head of Mexico’s car dealers’ association, AMDA, said imports of China-built cars had risen in the last four months of 2025 to soften the tariff, and that most Chinese brands had stocked about six months of inventory, some much more[3].

Then a drop, and a partial recovery

January 2026 brought 8,503 cars from China, the lowest month since at least January 2024, and only 780 of them were plug-ins. The first quarter came to 35,760, down 59% on 87,766 a year earlier. China’s own customs figures show the same break: exports of cars to Mexico fell 45.3% in January from a year earlier, by value[4].

From April the monthly counts moved back toward 2025. April to August 2026 came to 151,670 cars, 15% below the same months of 2025, and August (40,952) was higher than August 2025 (32,837). For January to August as a whole, cars from China fell 29%, from 265,722 to 187,430.

Our reading is that the stock bought in late 2025 covers much of the gap. The fourth quarter brought about 123,000 more cars from China than a year before. January to August 2026 brought about 78,000 fewer. The showrooms barely noticed. Mexico sold a record 1,014,715 new light vehicles in January to August 2026, up 4.7%, and the Chinese brands that report sales to INEGI gained share[4]. Many of those cars paid 20%, not 50%.

A different mix of cars

The 50% rate applies to petrol, diesel, hybrid, plug-in hybrid and electric cars alike[4], but the types didn’t move alike. From January to August, battery-electric cars from China fell 61%, from 45,269 to 17,640, and plug-in hybrids 62%, from 50,779 to 19,389. Petrol and diesel cars over 1.5 litres fell 77%. Small petrol and diesel cars, up to 1.5 litres, went the other way: up 10%, from 117,099 to 128,944. Hybrids that don’t plug in rose 17%, to 11,916.

So the average car from China got cheaper. Its declared value fell from about $14,700 to about $13,600, down 8%. Customs data can’t tell us why. Two explanations fit. The December rush was heaviest in plug-ins, so that is where dealers hold the most stock. And a flat 50% adds the least in dollars to the cheapest cars, so small petrol models are the easiest to keep shipping. We expect the plug-in numbers to say which one matters more once the stock runs down.

Who else ships cars to Mexico

Cars from all other origins rose 2.8% in January to August, from 276,550 to 284,196. Japan shipped 14% more. India, which also has no trade agreement with Mexico and faces the same rate[6], shipped 2% more. China’s share of the cars arriving by sea fell from 49% to 40%, and the total from every origin fell 13%, from 542,272 to 471,626. The other origins didn’t fill the gap.

Beyond cars

By declared value, goods from China arriving in Mexico by sea fell 2.8% in January to August, from $49.6 billion to $48.2 billion. Without cars, it was flat: $45.66 billion against $45.63 billion. The tariff hit a few lines hard and left the rest of the trade alone.

Footwear from China fell 52%, motorcycles 43%, apparel 28% and steel 19%. Textiles, footwear and apparel already carried higher tariffs from executive decrees in 2023 and 2024, which the 2026 law made permanent[1], so not all of that fall is this year’s change. Some sectors where the law added or raised tariffs held up or grew. Plastics rose 6.5% and aluminium 11.6%, while appliances, furniture, toys and paper slipped between 3% and 9%[1]. Trucks from China rose 7.8%, though light trucks are also listed at 50%[4].

What it means for forwarders

SME forwarders would not have captured this market anyway, so for them it is business as usual on FAK cargo, and specific verticals are still up for grabs. This is a macro play that goes straight to the top 25 forwarders, container carriers and ro-ro operators, or a combination of them, depending on the appetite of the car companies, which control the cargo.

Forwarders in Mexico have a harder time still. Mexican law does not yet recognise the freight forwarder as a line of business of its own, and a bill to add it to the Commercial Code is still before the Chamber of Deputies [7][8]. Operationally, that makes Mexico a mostly carrier-dominated market.

What we can and can’t say

The rush and the drop are in the data. That the late-2025 stock covers the gap is our reading, and it matches what AMDA said. We count shipments arriving by sea, so cars that reach Mexico by road or rail are not in these figures. Types come from the HS subheading on each customs line, and units are as declared. Values are declared customs values in US dollars, not adjusted for prices.

Data and method

Mexican import customs declarations for goods arriving by sea, by date of arrival, October 2024 to August 2026. Origin is the declared country of origin. Cars are HS heading 8703 without golf carts (8703.10) and quad bikes and motor tricycles (8703.21.01), counted in the units declared on each line. Plug-in means battery-electric (8703.80) and plug-in hybrid (8703.60 and 8703.70). Sector values are declared customs values in US dollars, January to August of each year, excluding 12 single customs lines of over $50 million each outside finished vehicles, so that one-off lots don’t swing the totals. No importer, brand or customer is identified.
