A floor-loaded container has its cartons stacked directly on the floor, usually to the roof, with no pallets. A palletized container carries the same cartons stacked and stretch-wrapped on pallets that a forklift moves in one lift. Floor loading fits more product in the box and costs nothing in pallets. Palletizing gives up some space and unloads in a fraction of the time. The difference shows up at the receiving dock, in unload labor, waiting trucks and what the warehouse will accept, so that is where the real difference lies.
What the two terms mean
Floor loading, also called floor stacking, means loading packed cartons straight onto the floor of a shipping container or trailer and stacking them in columns. It is the normal way an overseas factory fills a full container, and it is also used in domestic dry vans and truckload trailers. Less-than-truckload freight is almost always palletized, because LTL carriers move each shipment through several terminals on forklifts; LTL vs FTL covers where that line falls. Carriers assume a load is palletized unless you tell them otherwise, as ATS points out.
Palletizing means stacking cartons on a pallet, most often the 40 by 48 inch standard used across North America, and stretch-wrapping or strapping the stack into one unit. Each pallet becomes one handling unit for the forklift, the carrier and the warehouse system. Pallet specs vary by receiver, so it is worth knowing the standard pallet sizes before a supplier builds them.
Where floor loading saves money
Space. Pallets take up room twice: the wood itself, and the gaps between pallets and the container walls. Warp's freight glossary puts the gain at 20 to 30 percent more product by volume in a floor-loaded 40-foot container; Red Stag Fulfillment estimates 15 to 25 percent. For an importer close to needing a second container, that gain can be the whole decision. Our pallet calculator shows how many 40 by 48 pallets fit in a 20-foot, 40-foot or high-cube container, which is the quickest way to see what pallets cost you in floor positions.
Materials and weight. No pallets to buy, no stretch wrap, and no pallet weight counted against the container's payload; Red Stag puts a wooden pallet at 30 to 48 pounds each.
Origin labor. Many factories floor load by default and quote it that way. Asking for pallets can add a charge at origin, so get that number into the quote too.
Where it costs you back
Unload labor. A palletized container comes off with a forklift in 30 to 60 minutes, by Warp's estimate, while a floor-loaded 40-foot container takes a crew 3 to 5 hours to unload and palletize, and a 20-foot takes 2 to 3 hours. Red Stag's range is 4 to 8 hours for a floor-loaded 40-foot container against 1 to 2 hours for pallets. Watch the units: Warp's estimate is elapsed time for a four-person crew, and a warehouse that bills per person-hour multiplies the hours by the crew size. Someone pays for those hours. Warp says devanning or lumper fees at most US facilities run $300 to $600 per container; many warehouses bill hourly labor instead. Ask for the number before the container sails, not when the invoice arrives.
Detention. The truck, or the chassis under a container, waits while cartons come off by hand. Carriers allow a window of free time at the dock and bill detention after it; ATS says it usually starts at $50 to $75 per hour. A palletized load is normally clear of the dock inside that window. The usual answer for a floor load is to ask the carrier to drop the trailer or container and collect it later. That gives the dock time to work, and it can keep you clear of detention when the pickup is booked inside the free time your carrier allows for a drop, so get those terms in writing when you book.
Damage. Every carton is handled by hand at both ends, and nothing keeps the bottom layer off the container floor. Floor loading is a poor fit for fragile goods, and cartons at the bottom of a column carry the weight of everything above them for the whole voyage.
Receiving time. A palletized container is counted by the pallet and put away. A floor-loaded one is counted by the carton, palletized, and then put away, so it rarely lands on the warehouse's standard receiving timeline. If the cartons are mixed SKUs rather than grouped, add sorting on top.
Comparing the all-in cost
Factor | Floor loaded | Palletized |
|---|---|---|
Product per 40-foot container | More, by 15 to 30 percent by volume (Red Stag, Warp) | Less, since pallets and gaps use the space |
Pallet and wrap cost | None | Pallets, wrap, strapping |
Unload time | 3 to 8 hours by hand (Warp, Red Stag) | 30 minutes to 2 hours by forklift |
Unload charge | Per container or per hour; Warp cites $300 to $600 | Varies by receiver; Warp cites $0 to $150 for driver assist |
Detention risk on a live unload | High | Low |
Damage risk | Higher, with more handling and no pallet base | Lower |
Receiver acceptance | Varies; ask before it ships | The default at most docks |
To compare the two for your own order, put the freight you save on one side, whether that is a container you don't book or a lower cost per unit in the same one, and on the other side the unload fee, likely detention, extra receiving days and the damage you would expect on your product. When floor loading keeps the order inside one container instead of spilling into a second, the saving is the price of that second container, and that is the case that favors floor loading most. When the order fits in one container either way, the gap narrows to pallet cost against unload labor, and detention and receiving delay usually decide it.
What the receiving warehouse will accept
Every receiver has rules, and the first question to ask is what happens to a floor-loaded container at their dock. Some refuse them, some accept them for a flat fee, and many bill the labor by the hour.
Our own rules are a fair example of what a 3PL asks for. Receiving at Simpl is free for every client, including merch drops, as long as the shipment meets our receiving requirements: an inbound notice through our system at least 48 hours before arrival with an itemized SKU list, one SKU per master carton, a unique barcode on each unit you sell, standard 40 by 48 pallets within the height limit in our receiving guidelines, and a scheduled appointment for freight. A floor-loaded container does not arrive on pallets, so our crew unloads and palletizes it by hand, and that labor is billed at $45 per person-hour under our terms of service. Compliant pallets are received within 1 to 3 days; a container that has to be palletized first takes longer, and we confirm a timeline when you schedule it. The receiving guidelines list what else applies to container deliveries, and our answer on setup and receiving fees covers what is and isn't billed.
Amazon has its own floor loading policy for inventory going to FBA. It accepts floor-loaded truckload and container deliveries, and floor-loaded LTL from a carrier you book yourself, but asks sellers to palletize as much as possible, because palletized loads get earlier delivery appointments. The exception is the Amazon Partnered Carrier program. Its seller requirements say every partnered-carrier shipment that is not small parcel must be on pallets, and the partnered carrier program page says its carriers refuse LTL that is not on pallets; only partnered truckload and intermodal loads can be floor loaded. One of Amazon's own seller blog posts says partnered LTL can go floor loaded or palletized, so confirm what Send to Amazon offers for your shipment before you book, and plan on pallets if the option is not there. Floor loading at Amazon means loose boxes under 50 pounds that will be unloaded by hand; heavier boxes can be refused for safety. Boxes go in alternating columns no higher than 72 inches, with no straps or tape bundling them, at least 3 inches from the container walls and 8 inches of clearance at the doors, and the carrier has to book the appointment as a floor-loaded load in Carrier Central. A floor-loaded trailer with an uneven or corrugated floor is refused. Many sellers route the container to a prep warehouse instead and let it be palletized and labeled there; our FBA prep service receives inventory, preps and labels it to Amazon's rules and sends it on, and choosing a freight forwarder for FBA covers the ocean leg.
Before a floor-loaded shipment ships
- Tell the receiver it is floor loaded and get the unload charge in writing, hourly or per container, along with the carton count and total weight so they can staff it.
- Book the dock appointment with the notice the warehouse asks for, and say whether it is a live unload or a drop. Freight that shows up without an appointment can be refused.
- Ask the trucking or drayage carrier how much free time comes with the delivery and what detention costs after it. For a live unload of a floor-loaded container, assume you will use all of it.
- Send the advance ship notice: SKUs, quantities, carton count, container number and ETA. How to send inventory to a 3PL walks through the ASN, carton labels and what happens at the dock.
- Get the paperwork right. When the load moves on a domestic trailer, to a 3PL or to Amazon, the bill of lading is what the carrier and the receiver read. List cartons as the handling units with the piece count and total weight, and say in the special instructions that the load is floor loaded so nobody arrives expecting pallets. Our free bill of lading form generator builds a straight or VICS-style BOL with those fields, and what a bill of lading is explains the document itself. An ocean container moves under the bill of lading your carrier or forwarder issues, so the form matters for the truck legs.
- Pack for hand unloading. Keep cartons at a weight one person can lift (Amazon's 50-pound limit is a sensible benchmark for any receiver), label every carton with the PO number and SKU, keep each SKU together in the container, and stack in columns so the load does not shift.
Which one to choose
Floor load when the goods are durable, the cartons are uniform and grouped by SKU, container space is the constraint, and the receiver has quoted an unload rate you can live with. Palletize when the goods are fragile or heavy, the SKUs are mixed, the receiver or retailer requires pallets, the shipment goes LTL, or you need it received on the standard timeline.
There is also a middle path: floor load the ocean leg, then have the receiving warehouse or a transload facility near the port palletize the container, so the final delivery arrives on pallets. That is what a 3PL does at its own dock when it unloads and palletizes your container; the choice is whether you pay that labor once, to the warehouse that will store the goods, or to a separate facility first. If you are planning a container shipment to Simpl, tell us how it is loaded when you book the appointment and we will confirm a timeline with you.
