Usually when you want to file a trademark application you have to do it in a specific class that follows the official classification that each country chooses to use.
Most Latin American countries use the Nice Classification http://www.wipo.int/classifications/nice/en/ however some such as Argentina and Brasil have their own classification that varies compared to Nice's.
Some countries allow that in one single application several classes of products and/or services be included whilst others a separate application must be filed for each class of products and/or services.
Among the countries that allow them are: Peru, Chile, Colombia, Uruguay, Panama and Dominican Republic.
Countries that don’t allow multiclass trademark registration are:
Mexico, Brazil, Guatemala, Costa Rica, Honduras, El Salvador, Venezuela, Ecuador, Bolivia, Paraguay and Argentina.
