You may give away samples of your products, including food products. Tea samples, candy samples, supplements, herbal samples are all fine. An example of what is not permitted is preparing a cheese tray to entice visitors if your business is bodywork. If you plan to sell your food products they must be factory sealed. If they are not factory sealed, the selling of such is prohibited by the Convention Center rules. If you have any concerns or questions, please contact Expo management prior to setting up.
