The official time in Brazil is Brasília Time, which is three hours behind the Coordinated Universal Time (UTC-3). There is no longer “daylight saving time” (formerly, at a certain time of the year, clocks were advanced by one hour).
Argentina is also 3 hours behind UTC (UTC-3).
Paraguay is four hours behind UTC (UTC-4). The country has "daylight saving time", so when planning tours to the country, check out the local time.
In all three countries there are tolls on the highways. Depending on where you are going or where you will arrive via land, it is always wise to carry a quantity of local currency. In Puerto Iguazu, do not be surprised if you are approached, on the road returning from the Falls, to pay the tourist tax. The cost is very affordable. If you intend to return to Puerto Iguazu another day, keep the receipt and present it so that you will be charged only once.
Iguassu is also a shopping destination. For tourists who shop in Paraguay or Argentina and return by land, the allowed quota is $300. For those traveling by plane, the quota is $500. Be aware of the allowed quantities. In this guide (below) prepared by the IRS there is information.

In Brazil and Argentina, there are specific laws that prohibit smoking indoors. Paraguay also has legislation on this. Only in some places it is allowed to smoke indoors. When in doubt, consult the staff who work at the place where you are.
Clothing for some tours
It is worth reinforcing:
When visiting Foz do Iguaçu’s Mosque, it is necessary to take off shoes and respect the rules of visitation: women should cover their heads with scarves (provided by the Mosque) and be dressed in pants or long skirt. Men should be wearing pants or shorts below the knees.
In the Itaipu Special Tour, an internal tour of the Itaipu Power Plant, the minimum age for the tour is 14 years and it is necessary to wear clothes below the knee and closed shoes without heels.
For the other tours, comfortable clothes and shoes are ideal!
