I can think of dozens of companies that exist today in Argentina that could be exporting lots more.
Several already export, but due to the ridiculous taxes and rules for export, they have had to be very resourceful in doing so.
Darto is a company that exports 1 piece stamped steel frying pans (sartenes) all over the world right now, supplying restauants, chefs, and home chefs in Europe and the USA. Prior to the recent collapse of the economy by Milei, they were undercutting the prices of the fabricated aluminum frying pans many restaurants use, but with a product that functions more like cast iron. They have inspired a domestic competitor, Kaknay, which makes a less well designed knockoff.

Arbolito is the argentine factory of the german knife company Boker. Their chef knives are great, very high quality. They also make a full line of macho man everyday carry knives.

Nomade and Palo Santo are Argentine eyeglass frame manufacturers who both already export to some degree. Even with today's crazy economy, their frames run 2/3 or so cheaper than similar designer stuff in the USA, and Nomade uses plastics from the same factory in Italy that every major designer frame manufacturer uses globally.

Ombu and Pampero make high quality cotton work clothes- I have been wearing Carhartt and Dickies all my life, both the Argentine brands are equal or better, with high quality Argentine cotton. I buy them and take them to the USA to wear in my welding and machine shop- cheaper and better made than the vast majority of work clothes sold in the USA. they are both starting to do design colabs with Argentine fashion designers, much as Carhartt does in the USA, and those product drops sell out fast.
There is no Rubber work boots manufactured in the USA anymore, and the chinese crap they sell at places like Tractor Supply are terrible. Proforce and Calfor make excellent quality in Argentina. Steel toed, tough as nails, and well designed. And several companies are starting to make "fashion" rubber boots here, again, no competition in most western countries til you get to brands like the english Hunter, whose fashion rubber boots retail in the US and Europe for $175 to $200 and up.
Shoes, in general are a vastly underrecognized argentine market segment. Everybody whines that they cant get Nikes here, but Nikes are made in gigantic 10,000 employee factories in China and Vietnam, and are marked up several hundred percent- like Iphones, not a reproducible product pretty much anywhere.
The argentine shoe industry has manufacturers of machinery, tanners and synthetic material factories, findings factories, sole and heel factories, an entire infrastructure supporting several hundred manufacturers of shoes. Quality is actually great, prices are globally competitive, and design, like all Argentine design, is competitive as well.
Agricultural machinery- Several established manufacturers who have been around for decades, who already export, but certainly could do better with better market exposure, including Gherardi

https://www.mainero.com/en/about-us/. Argentina makes everything from shovels to tractors to drop forged wrenches and hammers.
Personally, I own a small japanese tractor, and, in the USA, the sources for small accessories like tillers that these companies make are not china- they are mainly italian, and not cheap. Argentina could absolutely compete, globally, in this market segment.
And hand tools as well- I probably own at least 50 hammers. I know hammers. And Gherardi and several of its competitors make excellent forged hand tools at competitive prices with the good euro ones (no real hammer makers left in the USA, so we get either cheap crap, or expensive Peddinghaus from Germany)
I could go on and on- many smaller market segments that each employ, now, tens of thousands of argentines, and, with proper government support, could employ many more.
Industrial design, in particular, is excellent in Argentina, and means that things like furniture, lighting, small appliances, clothing, shoes, tools, and more can easily compete globally.
The direct competition for Argentina would not be China- it would be Japan and Germany and Italy, all of which have hundreds of SMEs making relatively small quantities of high value added well designed premium products. And Argentina can and, in some cases does already, compete on many of those stages.
