What Makes Brazilian Products Popular in the U.S.?

 South American countries mostly provide food and minerals to the rest of the world. For example, the US buys iron ore and bauxite from Brazil, copper from Chile, coal from Colombia, silver, plum, and lithium from Bolivia and Peru, and crude oil from Brazil for Venezuela for a few years. As for food, they are always sending out different kinds of tropical fruits, like coffee, tea, nuts, suggar, orange juice, grapes, apples, mangoes, açaí, limes, bananas, and cocoa. The United States also gets most of its aluminum from South America. Alcoa and other companies are looking into bauxite, which is only found near the equator, for making alumina and aluminum bars. Embraer is a Brazilian company that makes airplanes. It is the third largest company in the world. Its major customers are US businesses and private owners who buy commercial and private jets. 

The US Air Force also uses the Brazilian Tucano-powered plane as a first flight for trainers

The USA also buys trucks from Brazilian companies that make VOLVO, Mercedes-Benz, and Volkswagen (now MAN) trucks. I'm not sure, but the Fiat Chrysler Auto giant plant in Brazil that makes some Jeep models (Renegade and) ships them all over the world. It also brings in Cherokee and Caravan from the US or Canada. Brazil is where Mercedes (C and GLA models), BMW (2 and 3 models), and Audi (A3 models) make and sell their products, so the USA may get these small cars. GERDAU, a Brazilian company, owns a number of steel plants in the United States. They also supply the US with steel bars and profiles from their own plants. TERNIUM, CSP, and Arcellor-Mittal also send steel slabs to the US. Brazil also has major owners and CEOs of Anhause Budweiser Interbrew, the world's best brewery, BRfoods, the world's best chicken company, JBS, the world's best beef company, Suzano Celulose, the world's best long-fiber paper company, Fisher Fruits, the world's best orange and apple juice company, and Cutrale, the world's best banana and orange juice supplier. Great wines from Chile and Argentina are sold all over the world, including to the United States. Small wines from Uruguay and Brazil are also exported to some countries, including the United States. Chilean salmon from fish farms are also sent all over the world, and live Amazonian fish from Brazil are the main source of fish for aquariums in the United States. Equator shrimp are also sent to the United States as well as the best flowers and veggies from Colombia. South America is also the main source of many drugs used today, like marijuana and cocaine. The USA is by far the biggest market, and pot use is now legal almost everywhere, but imports from South America have not been allowed yet. How many years until it's legal to drink alcohol in the US? We're already much more open-minded than Scandinavian countries, where the government runs stores that sell alcohol. These changes have been happening naturally in many societies since the dark ages, when life freedom wasn't even a dream for millions of our brothers and sisters who share America's freedoms, from North to South. For generations, our families have all left their homes to start new lives. 

The main things that Brazil sends to the US as exports are farm goods

One of the main countries that buys Brazilian goods is the United States. This includes straight imports and export-import consultants. What makes the relationship between the US and Brazil so important is that both countries accept and work with each other. The United States has one of the world's biggest economies, and Brazil has one of the world's biggest populations and land areas. Having this trade balance is good for both countries because each can give something different to the other. As Zaph correctly pointed out in his answer, services, some foods and drinks, but not all of them, have historically been cheaper in Brazil than in the US. But watch out, things are changing. In Brazil, the minimum wage has gone up by more than 500% since 2000. This means that service costs are going up, especially in towns. Like, in the place where I lived, the cost of having someone clean your apartment has gone up three to four times in the last few years. Forbes says that in Brazil, the middle class that used to be able to afford live-in maids is having to do without them more and more. If the higher cost of services is bad news for those who pay for them, it is definitely good news for those who provide them. In the past few years, millions of Brazilians have moved out of poverty and into Classe C, the lower middle class. It's only certain foods that can't be brought in because they aren't safe for consumption, like haggis; foods that are on lists to protect animals or plants, like whale, caviar from the Caspian Sea, etc.; or non-commercial fruits and veggies (and some animals, like bats) that can only be found in local markets.

There are also restrictions on plant and animal types that could start to spread quickly

It is hard, if not impossible, to bring certain foods into the US that, in their normal state, might contain bugs, worms, bacteria, fungus, viruses, or other organisms that could harm US crops, especially citrus. Some plants, like many Annonaceae found in Central and South America, don't sell well enough in the US to be worth bringing in. There are a lot of cheap gadgets, designer clothes, and cars. Aside from a few small things, you can find almost anything you could want in the US here in Brazil. At least in Rio and Sao Paulo, which are big towns. The price is what makes a difference. That's one reason why shopping tourism from Brazilians to places like Miami is such a huge business. There was a time before the current economic crisis when buying American goods in Miami was often cheaper than buying them here.
