Yes, as many as you like. Organizations often enter multiple categories, for example a product category together with a company or a professional category. Each nomination needs its own nomination form, so that the judges can review each nomination on its own merits. To save time, use the copy icon in your dashboard: it copies an existing nomination into a new one in the same award group, and you then change the details.

Each nomination has its own fee. The same product entered in two categories counts as two nominations. If you plan multiple nominations, a package costs less for each nomination: see the Fees page.
