UEFA's licensing partner Warner Bros Consumer Products, says more than 3000 different products will be made available, with around 70 percent clothing related.
The goods went on sale in the host nation of Portugal at the end of last year, with sales reportedly good.
The roll-out of the goods comes just three months before the tournament kicks-off, with England, Spain, Italy and Germany traditionally, the biggest consumers.
Said Warner Bros' commercial director Bernado Carvalho: "These products are not limited to just images of the logo or the mascot; they will appeal to the whole fan base, from young fans to women."
At a special ceremony in Lisbon yesterday, it was confirmed key Asian markets such as Korea, Japan and Thailand would also carry a range of the products.
Said Alan Ridley, senior director of the UEFA marketing operations centre: "The official licensing programme is one of the key elements for the organisation.
"When UEFA defined the whole concept, it wanted everybody to know how big and important EURO 2004 is and that UEFA has chosen to use Portuguese licensees to get the country involved in the atmosphere of the event. The licensees we have chosen provided us with a huge variety of exciting and creative products."
Warner Bros picked 28 licencees to provide the products.
