Trade fairs are generally attended by industry professionals including manufacturers, wholesalers, dealers and press. And most professional trade fairs are not open to the public. That’s the reason trade fairs are classified as either “consumer fairs” and “trade only”. However, there are a few trade fairs that are open to both business professionals and general public. Examples of such trade fairs include BAU Munich and Bauma Munich. These are among the largest trade fairs and are open to business professionals, general public, students and institutions.
