If Oil Did Not Drive Uruguay's Biggest Import Bill Since 2016, What Did?

In October 2026, Uruguay paid US$1.43 billion for its imports, more than in any month since our customs data begins in January 2016. The easy answer arrived on two tankers: both of October's crude oil cargoes came from the United States, at a price per tonne more than half again what Uruguay paid a year earlier. But put October next to October 2025 and the easy answer falls apart, because Uruguay's fuel bill was lower than a year ago. So what filled the rest of the bill? The customs declarations point somewhere else: car lots, hospitals, feed bins, butcher shops and one cargo of sulphur bought at several times last year's price.

The obvious suspect

Start with the size of the thing. Imports rose to US$1,434.1 million in October, from US$1,377.5 million in September and US$1,300.1 million in October 2025. Exports went the other way, falling 10.8% to US$893.7 million as soybean shipments dwindled, so the monthly deficit widened to US$540.4 million.

Oil is the natural suspect, and against September it is guilty. Of the US$56.6 million rise from September, crude oil accounts for US$54.9 million: two cargoes from the United States of about 134,000 tonnes each, US$225.5 million together. They were declared at about US$842 a tonne, against US$744 in September and US$543 in October 2025, while the tonnage was only 8.4% above a year earlier. That is a price story. Brent crude averaged US$125.0 a barrel in October, almost double the US$64.7 of a year earlier, according to the World Bank's monthly averages. Oil broke back above US$100 a barrel in September as fighting escalated in the Middle East, CNBC reported, and reached a five-month high on 22 October after Houthi attacks in Saudi Arabia, Reuters reported, via The Star.

The alibi

Here is where it gets interesting. Compare October with October 2025 instead of September, and oil drops out of the picture. Fuel imports as a whole (HS chapter 27, crude plus refined products) were US$238.8 million, 2.4% less than a year earlier, on 26.6% fewer tonnes.

The reason is what Uruguay was buying a year ago. In October 2025 it imported US$99.1 million of refined fuels, mostly diesel and gasoline, on top of its crude. This October, refined fuel imports were US$5.1 million. Crude got much more expensive, refined fuel imports almost disappeared, and the two nearly cancelled out. The customs data does not say why Uruguay bought so much ready-made fuel in late 2025, only that August 2025 had no crude cargo at all.

So the year-on-year rise came from somewhere other than fuel. The non-fuel part of the bill reached US$1.20 billion, the highest month since January 2016 and 13.3% more than the US$1.06 billion of October 2025, on only 3.1% more tonnes.

So who did it?

No single product. The rise is spread across the economy, which is part of why it is easy to miss:

• Passenger cars added US$46.9 million, to US$130.7 million, the fourth monthly rise in a row and the highest since 2016.
• Pharmaceuticals added US$19.5 million, mostly vaccines and blood products, which more than doubled to US$28.8 million.
• Machinery added US$19.3 million.
• Cereals added US$17.6 million: grain maize from Paraguay, 93,600 tonnes against 19,100 a year earlier. The drought that halved Uruguay's soybeans also hit its maize, Prensa Latina reported, and Paraguay's own harvest ran late, into August to October, Tardáguila Agromercados reported.
• Sulphur added US$16.5 million: one cargo of about 13,200 tonnes from the United States at roughly US$1,255 a tonne. The same importer paid US$213 to US$349 a tonne in 2025. A normal cargo size at three to six times the price.
• Meat added US$11.2 million, mostly Brazilian beef, in a country whose largest export is beef (Uruguay XXI). Brazilian steers were about 25% cheaper than Uruguay's in July, Blasina y Asociados reported, and Uruguayan steers reached US$6 a kilo carcass weight for the first time in late October, El Observador reported.

Together the rise from October 2025 came to US$134.0 million. Fertilizers and electrical equipment went the other way, down US$14.9 million and US$12.5 million.

The twist: the cars got more expensive

The largest single piece, cars, has a detail that changes how to read the whole month. Uruguay imported 7,010 cars in October, 20.2% more than a year earlier, but paid 55.8% more for them. The average declared value per car rose to about US$18,700 from about US$14,400. Uruguay did not just import more cars; the cars that arrived were pricier.

The electric cars explain it. Last month in Below Deck we sorted electric car imports by declared value into the three bands of the IMESI excise tax that starts on 1 January 2027: exempt up to US$19,000, 5% up to US$27,000 and 9% above, as El Observador reported. Cars above US$27,000 had jumped from 73 in August to 1,023 in September, and we wrote that if this was a pull-forward ahead of the tax, premium arrivals should stay high through December.

October passed that test. Electric cars declared above US$27,000 rose again, to 1,447, and 1,329 of them came from China. The exempt band fell to 2,306 cars, from 3,561 in August. The average declared value per electric car reached about US$21,400, from about US$15,900 in August.

The policy did not blink. In early October the Ministry of Economy was weighing a very short delay, Búsqueda reported; on 20 October the minister ruled out any flexibility, El Telégrafo reported, noting that importers had sped up electric arrivals ahead of the new scale. Researchers at the Catholic University of Uruguay's international business institute read the rise the same way, as possible early buying, Reporte Asia reported.

My read: importers are landing the cars that will cost the most to bring in after January while the tax is still zero. The data shows the timing and the price mix; it cannot show anyone's intent, and the declared value per car only approximates the tax's CIF test.

Trade with the U.S.: the crude that tipped the balance

Where the oil came from has a second consequence. Uruguay's imports from the United States reached US$292.7 million in October, the highest since January 2024, against US$125.6 million a year earlier. Exports to the United States were US$122.2 million, up 33.9% from October 2025.

Crude and the sulphur cargo made up 82.7% of what Uruguay bought from the United States in October. On the other side, frozen beef led, at about US$7.90 a kilo against US$6.40 a year earlier on almost the same tonnage, and the United States is again Uruguay's top beef market by revenue this year, ahead of China: US$700.1 million to US$680.3 million from January to October, Ámbito reported. That happened despite an extra 12.5% U.S. tariff on most Uruguayan goods since 24 July, MercoPress reported, because beef is outside it, El Cronista reported, and despite Uruguay being left out of a temporary U.S. quota of 300,000 tonnes of duty-free lean beef trimmings, MercoPress reported.

Across the year, crude changes the relationship. From January to October 2026, Uruguay bought US$1.30 billion from the United States and sold it US$1.11 billion: a deficit of US$184.5 million, against a surplus of US$89.1 million in the same months of 2025.

The United States supplied 48.7% of Uruguay's crude imports by value this year, against 38.6% a year earlier, and both October cargoes were American.

That looks at odds with what the state oil company reports: it now buys more Argentine Medanito crude than U.S. WTI, Búsqueda reported, though purchases and customs arrivals are measured differently. The U.S. side shows the oil leaving: official Census data for September, released on 4 November, puts U.S. exports to Uruguay at US$368.9 million, against US$104.8 million a year earlier, most likely including the two cargoes that landed in October.

So what set the high?

Not oil, or not only oil. One expensive U.S. crude cargo lifted October above September. Against a year earlier, the fuel bill was smaller and the high came from everything else: more and pricier cars ahead of a tax, more medicines and machinery, Paraguayan maize after a drought, Brazilian beef while Uruguayan cattle sell at record prices, and a sulphur cargo at several times last year's price.

It adds up. From January to October, imports rose 10.9% to US$11.96 billion while exports were flat at US$9.50 billion, so the deficit in this customs data, which leaves out pulp and other exports shipped from free zones, nearly doubled, to US$2.46 billion from US$1.28 billion.

What we do not know yet: whether the crude price per tonne peaked in October, and how much of this year's car buying was simply borrowed from 2027.

What to watch

• Mid-December 2026: Uruguay's November customs data. If importers are getting ahead of the tax, premium electric arrivals should stay high in November and December.
• 1 January 2027: the IMESI on electric cars starts, as the minister confirmed in October.
• January and February 2027: the first months under the tax. A drop in premium electric arrivals would support the pull-forward reading; steady arrivals would weaken it.
• 8 December 2026: the U.S. Census October release, the next look at the oil leaving the United States for Uruguay.
• The next crude cargoes: whether the declared price stays near US$842 a tonne, and whether they keep coming from the United States.
