SPI restricts exhibitors from hosting or participating in competing or conflicting events or activities that occur during official SPI show hours. Exhibitors violating this policy will be subject to cancellation of their booth without refund and may not be invited to participate in future SPI  exhibitions. Booth Personnel are not permitted to promote the exhibiting company outside the contracted exhibit space. All marketing must remain within the contracted exhibit space. Marketing materials may not be placed on conference tables or other areas that are not within the boundaries of the booth, both inside and outside of the exhibit hall. Show management reserves the right to remove individuals or discard display materials that do not comply with these guidelines. SPI  has a zero-tolerance policy regarding suitcasing. Please note that while all meeting attendees are invited to the exhibit floor, any attendee who is observed to be soliciting business in the aisles or other public spaces, or in another company's booth, will be asked to leave immediately.

What is suitcasing? Suitcasing is a business practice in which unethical companies will gain access to an event by obtaining some type of event credential (attendee badge, expo-only badge, etc.) and then solicit business in the aisles or other public spaces used for the conference. This practice skirts the support of the organizer and the industry.

What can you do? Please report any violations you observe to the exhibits manager, other SPI staff, or conference security. The exhibits manager will investigate all complaints of suitcasing. SPI recognizes that suitcasing may also take the form of commercial activity conducted from a hotel guest room or hospitality suite, a restaurant, or any other public place in proximity to our event. For the purposes of this policy, suitcasing violations may occur at venues other than the exhibition floor and at other events. It is for this reason SPI must be informed of any hospitality suites, and expressed consent must be given prior to the event.
