For an exhibitor sending samples to an exhibition for the first time, the most surprising charge on the invoice is usually not the booth rent but a line marked "material handling" or "drayage" that is quite a bit higher than first expected.
What is drayage
What is drayage in the exhibition industry's own terms? It is a service performed by the official service contractor, covering moving sample goods from the receiving dock to the assigned booth, removing and storing empty crates and boxes for the duration of the event, then returning the crates and moving the goods out to the dock for the carrier to collect at the end. The more commonly preferred industry term today is material handling, with the same meaning.
Why it is a two-way charge
What surprises many exhibitors most is that drayage is charged for both trips: the trip in during setup and the trip out during dismantling, even though in practice the goods travel only a short way from the dock to the booth. The fee is calculated on the weight or volume of the shipment, regardless of the actual distance moved inside the show floor.
Telling drayage apart from long-distance freight
Many companies confuse drayage with the cost of shipping sample goods from their own warehouse to the exhibition venue. The two are entirely separate. Long-distance freight, from the warehouse to the exhibition's receiving dock, is handled by a carrier or freight forwarder and charged by distance and mode of transport (road, sea, air). Drayage starts being charged only from the moment the goods arrive at the exhibition's receiving dock.
Where the empty crates go during the exhibition
A part of drayage rarely mentioned is the handling of empty crates, boxes and pallets after the sample goods have been moved into the booth. Exhibitors aren't allowed to keep empty crates at the booth for fire-safety reasons and the general appearance of the show floor. The OSC labels, collects and takes all the empty crates to a separate storage area, then returns them to the right booth at dismantling time so the exhibitor can pack up the goods to take home. That is also why the drayage fee is charged as a package for this whole storage process, not just the transport step.
International sample shipping needs two more roles
When an exhibition has foreign exhibitors, the sample shipping process needs two more specialized roles. First is an international freight forwarder, usually designated by the organizer or the OSC as the official contact, responsible for managing goods moving into and out of the host country. Second is a customs broker, who ensures the paperwork is complete so goods clear customs legally and on schedule. Both roles matter when a shipment is held up during clearance and needs to be returned to its country of origin.
Three things to do before shipping samples
First, check the late-arrival policy in the exhibitor manual carefully, since each exhibition sets different receiving deadlines and goods arriving after the deadline may incur an urgent-handling fee. Second, review the delivery schedule in advance, usually arranged from the front to the back of the show floor, to avoid sending goods in the most congested time slot. Third, estimate the weight and volume of the shipment as accurately as possible before ordering the service, since these are the basis for the two-way drayage charge, and a big gap between estimate and reality usually leads to on-the-spot extra costs.
Why you shouldn't skip this item in your budget
For a company joining an international exhibition for the first time, the initial budget usually lists only the booth rent, the booth build cost, and flights and hotels for staff. Drayage gets missed because it doesn't appear clearly until the invoice comes from the OSC after the exhibition ends. For heavy or bulky shipments such as display machinery, this fee can take a significant share of the total participation budget, large enough to affect the decision whether to bring real samples or just display images and catalogues instead.
Understand drayage when you first build your exhibition budget, rather than counting only booth rent and staff flights. It's the cost gap companies miss most easily in the whole preparation process.
