You can ship a pallet of stainless steel bearings and a pallet of fluffy napkins for the same price — and that is not a bug, it is the system working exactly as designed. So Daniel sent us this one about freight pricing, and he is asking about two things that trip up almost everyone the first time they move from domestic e-commerce into international shipping. First, why pricing is volumetric rather than weight-based, and whether it really means steel and napkins cost the same to move. Second, the whole LCL versus FCL decision — when you are not filling a whole container, what is the minimum unit you are actually buying, and what pallet standard governs the quoting, especially if you are shipping out of Asia.
These two things interact in ways that most explainers miss, because they treat volumetric pricing and container sharing as separate topics. They are not. The same logic — carriers sell space, not mass — runs through both of them. Once you see that, the whole pricing structure clicks into place.
Let us unpack both of those mental shifts, starting with the one that trips up almost everyone first: volumetric pricing.
The core thing to understand is that international carriers are in the business of selling container volume. A standard twenty-foot container holds about thirty-three cubic meters. It also has a weight limit, roughly twenty-eight thousand kilograms of payload. For most consumer goods, the container fills up long before it hits that weight limit. So the scarce resource is space, not lifting capacity.
Which is why they do not care what you put in the box, as long as it fits. The napkins and the bearings occupy the same slot on the vessel.
The way they translate that into pricing is a formula called volumetric weight, or dim weight. The standard international divisor is six thousand. You take the length times width times height of your box in centimeters, divide by six thousand, and that gives you the volumetric weight in kilograms. You pay for whichever is greater — the actual weight or the volumetric weight.
Walk us through a concrete example.
A box that is one hundred twenty centimeters by eighty centimeters by one hundred centimeters — roughly the footprint of a Euro pallet, stacked a meter high. The math: one twenty times eighty times one hundred gives you nine hundred sixty thousand cubic centimeters. Divide by six thousand, you get one hundred sixty kilograms volumetric weight. If that box actually weighs fifty kilograms, you still pay for one hundred sixty. The carrier is charging you for the space you consume, not the heft.
Where does that six thousand divisor actually come from? Because it looks arbitrary until you trace it.
It comes straight from the container math. A standard twenty-foot container has about thirty-three cubic meters of capacity and a payload limit around twenty-eight thousand kilograms. That works out to roughly one thousand one hundred eighty kilograms per cubic meter — the density threshold where a shipment is dense enough to hit the weight limit before it fills the volume. The industry rounds that down to one thousand kilograms per cubic meter. One cubic meter is one million cubic centimeters. Divide that by one thousand kilograms, and you get one thousand cubic centimeters per kilogram — which is where the six thousand divisor comes from for the standard formula that uses centimeters. It is baked into the physical constraints of the shipping container itself.
The formula is not some arbitrary accounting convention. It is a compression of the entire physics of containerized shipping into a single number.
Both FedEx and Freightos use this same six thousand divisor for international shipments. It is an industry standard. Some carriers use a five thousand divisor for domestic air freight because aircraft have tighter volume constraints, but for ocean freight, six thousand is the reference.
Here is the paradox that Daniel was poking at. You have two boxes, both fifty kilograms actual weight. One is stainless steel bearings — dense, compact, maybe the size of a shoebox. The other is memory foam pillows, fifty kilograms of them, which might fill half a pallet. The steel box has a tiny volumetric weight, so you pay for the actual fifty kilograms. The pillow box has a massive volumetric weight — maybe one hundred sixty kilograms — so you pay for one hundred sixty. The effective cost per kilogram for the pillows is three to five times higher.
That is the mental wall for someone coming from domestic e-commerce, where you are used to weight-based pricing or flat-rate boxes. You quote a customer based on the product weight, and then the international freight quote comes back and it is three times what you expected. Freightos research shows that dim weight can increase shipping cost by three to five times for low-density goods. If you are selling pillows, plush toys, clothing, certain plastic goods — anything that takes up a lot of space relative to its weight — your shipping economics are fundamentally different from someone shipping dense industrial parts.
The carrier is indifferent between the steel and the napkins because they are selling the same thing in both cases: a slot on the ship. The napkin shipper just needs more slots per kilogram of product.
That indifference is the key insight. The ship's cargo hold fills before it sinks. For most consumer goods, volume is the binding constraint, not weight. So the pricing system evolved to charge for volume. The weight-based pricing that domestic shippers are used to is actually the historical anomaly — it only works when you are moving things by truck where weight limits matter more than volume, or when your packages are small enough that carriers can average out the density across millions of parcels.
What is interesting is that this means there is a break-even density. If your product is denser than about one hundred sixty-seven kilograms per cubic meter — which is one thousand divided by six — you pay by actual weight. Below that, you pay by volume. And a lot of consumer goods fall below that line.
The practical implication for someone starting out in international e-commerce is that you must calculate dim weight before you quote a customer. You cannot price shipping based on the product weight and hope it works out. You need the box dimensions, you run the formula, and you compare. If the volumetric weight is higher, that is your true shipping weight for pricing purposes.
This gets even more interesting when you think about packaging optimization. If you are shipping low-density goods, reducing your box size by even a few centimeters can have an outsized effect on cost, because you are shaving cubic centimeters off the numerator of that fraction.
Yes — and this is where the modular logic from the warehouse extends into freight. If you have already internalized the Euro box as the basic unit of storage, the natural next step is thinking about how those boxes stack onto a pallet, and how that pallet fits into a container. The volumetric pricing formula is the financial expression of that physical nesting.
We have established that carriers charge for space, not mass. The formula is length times width times height in centimeters divided by six thousand. You pay the greater of that or actual weight. And for low-density products, this can multiply your shipping cost by several times. That is the first mental shift.
Now we need to look at how this same logic plays out when you are not filling a whole container — which is where LCL shipping and pallet standards come in. Because the minimum unit you are buying in that world is not a box. It is a pallet position.
Before we go there, let me just sit with the napkins-and-steel thing for one more beat, because I think it is genuinely counterintuitive. Most people's intuition about pricing is that it reflects cost. Heavier things cost more to move because they burn more fuel. That intuition is not wrong — it is just incomplete. In international shipping, the dominant cost is the vessel, the port fees, the handling — and those scale with the number of containers you move, not the mass inside them. The marginal fuel cost of a heavier container is real but small compared to the fixed cost of the container slot itself.
That is exactly right. And it is why the volumetric system is not some clever trick carriers use to squeeze more money out of pillow shippers. It is the pricing system that aligns the carrier's incentives with the actual economics of the vessel. If carriers charged purely by weight, they would lose money on every container of pillows, because that container takes up a slot that could have held something denser and more profitable under the weight-based system. The dim weight formula corrects for that.
It is less a markup and more a normalization. It makes the napkins and the steel comparable by converting them both into the same unit: container space consumed.
That unit — the cubic meter, or its parcel-sized cousin the volumetric kilogram — is the real currency of international freight. Once you start thinking in those terms, a lot of decisions that seem complicated become straightforward. Should you vacuum-pack those pillows? Yes, because you are literally compressing your cost basis. Should you ship that half-empty box? No, because you are paying for air.
There is also a knock-on effect here. The dim weight formula creates a natural incentive for manufacturers to design products that are denser or more compact. If you are competing on a global market and your competitor's widget packs into a box that is twenty percent smaller than yours, their shipping cost is twenty percent lower. That is a structural advantage that has nothing to do with the product itself.
IKEA is the classic example — their flat-pack design is not just about the customer experience, it is fundamentally a freight optimization strategy. Every cubic meter they save in the box is a cubic meter they do not pay for on the ship. When you are moving millions of units, that adds up to an enormous cost advantage.
The dim weight formula is not just a pricing mechanism. It is a selection pressure on global trade. Products that pack efficiently have a built-in cost advantage. Products that do not — pre-assembled furniture, large plush toys, packaging that prioritizes shelf presence over shipping density — carry a structural cost penalty that gets baked into their final price.
Which brings us back to Daniel's question about LCL and pallets. Because once you understand that carriers sell space, the next question is: what is the minimum chunk of space you can buy, and how is that chunk defined? And the answer is not as simple as "a box.
In the parcel world, you buy by the volumetric kilogram. In the freight world, you buy by the cubic meter, and the minimum unit is typically a pallet position. And the pallet that the global system has standardized around for quoting — even when shipping from Asia — is the Euro pallet, one hundred twenty by eighty centimeters. That is where we will pick up next.
Because it turns out the same modular logic that gave us the Euro box in the warehouse also gave us the Euro pallet in the container. And the way those two systems interlock — the box on the pallet, the pallet in the container, the container on the ship — is one of those invisible infrastructures that makes global trade work, and that nobody explains to you when you are just trying to figure out how much it costs to ship your product.
The Euro pallet is the Rosetta Stone here. One hundred twenty by eighty centimeters. It is not the only pallet in the world — not even close — but it is the one the quoting system speaks. Sixteen of them fit perfectly into a twenty-foot container, two rows of eight. Eighteen into a forty-foot. That fit is so tight and so efficient that it became the reference standard for LCL pricing globally, even in markets where the local pallets are completely different.
If I am a freight forwarder in Shenzhen and you walk in asking for an LCL quote, I am probably going to ask for your pallet dimensions, and I am pricing against a mental grid of Euro pallet positions — even though the pallets actually moving around that warehouse might be the Asian one hundred ten by one hundred ten.
That is exactly what happens. And this is where the two pricing pillars connect. The volumetric formula we just walked through is the parcel-level expression. LCL pricing is the pallet-level expression of the same principle — charged per cubic meter or per one thousand kilograms, whichever is greater. Same logic, different unit of account. The dim weight divisor of six thousand for parcels is the cubic meter threshold of one thousand kilograms for freight, just scaled down.
The entire system is fractal. Whether you are shipping a single box or a pallet or a container, the pricing algorithm is asking the same question: how much space are you consuming relative to the weight? And it charges you for whichever one is the binding constraint.
The Euro pallet is the physical interface where that fractal logic snaps into the container grid. The container itself is standardized globally through ISO six six eight — the corner castings, the twist locks, the forklift pockets are identical whether you are in Rotterdam or Shanghai or Los Angeles. That physical infrastructure is universal. But the pallet you place inside it is not. So the industry converged on the Euro pallet as the quoting lingua franca because it maximizes container floor efficiency. A one hundred ten by one hundred ten Asian pallet leaves dead space along the edges of a twenty-foot container — you lose about seven percent of floor utilization.
Which means you pay for air, again. Same lesson, different scale.
For someone new to international e-commerce, this is the hidden friction point. You negotiate an LCL rate based on pallet positions, you build your cost model around that, and then your supplier in Asia loads everything onto a non-standard pallet that is five centimeters wider than what the forwarder quoted. Suddenly your goods do not fit the slot, or you get hit with a surcharge, or your shipment gets delayed while they re-palletize at the consolidation warehouse.
The practical takeaway even before we get to the mechanics is that the pallet standard is not a detail you can delegate to your supplier and forget about. It is a pricing variable.
Let's make this tangible with the steel-versus-pillows comparison, because the numbers are what make the mental shift stick. Take a box that is fifty kilograms of steel bolts. That box might be forty centimeters by thirty by thirty — about thirty-six thousand cubic centimeters. Divide by six thousand, volumetric weight is six kilograms. Actual weight is fifty. You pay for fifty. Now take fifty kilograms of memory foam pillows. To fit fifty kilograms of pillows, you need a much bigger box — say one hundred twenty by eighty by one hundred centimeters, the Euro pallet footprint we keep circling around. That is nine hundred sixty thousand cubic centimeters. Divide by six thousand, volumetric weight is one hundred sixty kilograms. You pay for one hundred sixty, even though the box only weighs fifty.
The pillow shipper is paying more than three times the freight cost for the same actual weight. And that is not a surcharge or a penalty. It is just the math of the space they occupy.
Freightos has documented this — for low-density goods, dim weight can push your shipping cost up by a factor of three to five times what you would expect from weight alone. If you are selling something like plush toys or insulated jackets, your freight quote is not going to look anything like your domestic shipping experience.
There is a breakpoint here worth nailing down. The density threshold where you flip from paying by weight to paying by volume is about one hundred sixty-seven kilograms per cubic meter. Anything less dense than that — and a lot of consumer goods are — you are in volumetric territory.
Clothing averages around one hundred to one hundred twenty kilograms per cubic meter. Pillows and bedding can be as low as thirty to fifty. Plastic toys, maybe eighty. All of these live below the line. Meanwhile, books are around five hundred kilograms per cubic meter — dense enough to pay by weight. Ceramic tiles, even more so. The product category you are shipping fundamentally determines which pricing regime you are in.
Which means if you are launching an international e-commerce business selling low-density goods, you are effectively in a different freight market than someone shipping dense industrial products. Your cost structure is higher by design, not by inefficiency.
That is why you must calculate dim weight before you quote a customer. The formula is simple — length times width times height in centimeters, divided by six thousand — but skipping it is the single most expensive mistake new operators make. They quote a customer based on the product weight, get the freight invoice, and realize they are underwater on shipping.
What is also interesting is that this creates a packaging optimization lever that domestic sellers rarely think about. If you can compress your product or redesign your box to shave ten centimeters off one dimension, you are directly reducing the numerator in that fraction. For a low-density product, a fifteen percent reduction in box volume is a fifteen percent reduction in freight cost.
Vacuum packing is the extreme version of this. You take something like pillows or comforters, suck the air out, and suddenly the volumetric weight drops by sixty or seventy percent. The product is the same, the customer experience is the same once they open it, but your freight economics are transformed.
The carrier is not losing out here either. If they charged purely by weight, they would be incentivized to avoid low-density cargo entirely — it would fill their containers while generating less revenue per slot. The dim weight formula aligns things so that a container of pillows and a container of steel generate comparable revenue per voyage. The carrier becomes indifferent to what you ship.
That indifference is the tell that the system is working. The carrier is selling container volume, not mass. The ship's cargo hold fills before it reaches its weight capacity for almost all consumer goods. So the scarce resource is space, and the pricing reflects that scarcity. Weight-based pricing would misprice the actual constraint.
Now we extend that same logic up one level — from the box to the pallet, and from the pallet to the container slot. When you are not filling a whole container, you are in LCL territory — Less than Container Load. FCL, Full Container Load, means you book the entire twenty-foot or forty-foot box. Your goods go in, the doors close, and nobody touches them until they reach the destination. LCL means you are buying a slice of a shared container.
For someone moving less than about fifteen cubic meters — which is most new e-commerce operators — LCL is the default. You do not have enough volume to justify a whole container. A twenty-foot container holds roughly thirty-three cubic meters. If you are shipping less than half of that, LCL is almost certainly cheaper than paying for empty space in an FCL. But the minimum unit you are buying in LCL is not a box. It is not a carton. It is a pallet position.
The freight forwarder is thinking in terms of slots on a grid. How many pallet positions do you need, and what are the dimensions of each pallet?
The pallet they are almost certainly using as their reference is the Euro pallet — one hundred twenty by eighty centimeters. Even when you are shipping out of Shenzhen or Shanghai, the forwarder's quoting system is built around that footprint. Sixteen Euro pallets fit perfectly into a twenty-foot container — two rows of eight. Eighteen into a forty-foot. That fit is so tight and efficient that it became the quoting standard globally.
Which is strange when you think about it. You are in Asia, surrounded by Asian pallets — one hundred ten by one hundred ten is common — and yet the forwarder is pricing against a European standard.
It is strange until you look at the container math. A one hundred ten by one hundred ten pallet does not divide evenly into the internal width of a standard container, which is about two hundred thirty-five centimeters. You get awkward gaps along the edges. You lose roughly seven percent of floor utilization. The Euro pallet, by contrast, nests perfectly — two across leaves minimal wasted space. So the industry converged on it as the pricing lingua franca, even in markets where the physical pallets are different.
The container infrastructure itself is the reason this works at all. The corner castings, the twist locks, the forklift pockets — those are standardized globally through ISO six six eight. You can load a container in Shanghai and unload it in Rotterdam using the same equipment. The pallet inside is the variable.
When you book LCL, you tell the forwarder your pallet dimensions, and they map those onto the Euro pallet grid they use for pricing. If your pallet is one hundred twenty by eighty, it slots right in. If it is one hundred ten by one hundred ten, you are consuming more container floor than the grid assumes, and you will pay more per cubic meter — or get hit with a surcharge at the consolidation warehouse.
There is a real-world gotcha here that catches people. You negotiate a rate based on, say, eight pallet positions. Your supplier in Asia loads everything onto pallets that are five centimeters wider than what you quoted. The forwarder's consolidation team discovers this when they go to load the container, and suddenly your eight pallets do not fit the allocated slots. Best case, you pay a surcharge. Worst case, your shipment gets held while they re-palletize, and you miss your vessel.
Re-palletization is not free. You are paying for labor, for new pallets, potentially for re-wrapping. And your goods are being handled an extra time, which increases damage risk. All because the pallet dimension was treated as an afterthought rather than a pricing variable.
The pallet standard is not a packaging detail you delegate to the supplier. It is part of your cost model.
Now, the pricing itself extends the same volumetric logic we just walked through. LCL is charged per cubic meter or per one thousand kilograms, whichever is greater. It is the same "greater of" structure as dim weight, just at a different scale. The parcel formula uses six thousand as the divisor to get to volumetric kilograms. The freight formula uses one thousand kilograms per cubic meter as the threshold. They are the same equation, just with different units.
The two systems converge. Dim weight for parcels, CBM-based pricing for palletized LCL — both are asking the same question. How much space are you consuming relative to weight? And both charge you for whichever one is the binding constraint.
Here is where the hidden costs of LCL start to stack up. Consolidation fees — the forwarder charges you to combine your pallets with other shippers' goods into a single container. Deconsolidation fees at the destination — someone has to break that container apart and sort the pallets. Each of those handling steps adds cost and time. An LCL shipment from Shanghai to Rotterdam might take thirty-five to forty days door to door, where an FCL shipment on the same route might take twenty-eight. That extra week is your goods sitting in consolidation warehouses, being moved on and off forklifts.
Every touch is a chance for something to go wrong. More handling, more damage risk. If you are shipping something fragile or high-value, that is not a trivial consideration.
Which is why there is a counterintuitive breakpoint. For very low-density products — pillows, insulation, certain packaging materials — FCL can make sense at lower volumes than you would expect. Because volumetric pricing means you are paying for the space either way. If your product is light and bulky, a full container of it might cost less per unit than multiple LCL shipments, even if you are not completely filling the container. The consolidation and handling fees on the LCL side can tip the math.
The napkins-and-steel logic ripples all the way through. The same product characteristics that determine your dim weight also determine whether LCL or FCL is the right call. Low-density goods get penalized at every level of the system — unless you optimize for it.
What do you actually do with all this? Three things you can take to your next shipment.
First, calculate volumetric weight before you ever ask for a quote. The formula is length times width times height in centimeters, divided by six thousand. Compare that to your actual weight. The bigger number is what you will pay. For LCL, same logic — total cubic meters versus total weight in metric tons. Whichever is greater sets your rate. Do this math before you price anything for a customer.
The formula is simple enough that there is no excuse not to. You need a tape measure and a calculator. If you skip this step, you are essentially guessing at your largest variable cost.
Second takeaway: standardize on Euro pallet dimensions for your export packaging. One hundred twenty by eighty centimeters. Even if you are shipping from Asia, even if your supplier defaults to something else. It maximizes container floor efficiency, it avoids surcharges for non-standard sizing, and it means your pallets slot cleanly into the forwarder's quoting grid without surprises.
Tell your supplier explicitly. Do not assume they will figure it out. Put the pallet spec in the purchase order. It is a five-second line item that can save you hundreds of dollars in re-palletization fees and missed sailings.
Third: if you are shipping low-density products, run the FCL math sooner than you think you need to. Volumetric pricing means you are paying for space either way. A full container of pillows might cost less per unit than three or four LCL shipments once you factor in consolidation fees, deconsolidation, and the extra handling risk. The break-even is not just about volume — it is about density times volume times handling cost.
The napkin shipper who assumes LCL is always cheaper for small volumes is probably leaving money on the table. Run both numbers.
Before we wrap, let us zoom out and ask where this is heading. Because the system we just described — volumetric pricing, pallet standardization, the whole container grid — it is not static. Container shipping is under real pressure to decarbonize, and that is going to force some interesting conversations about how freight is priced.
If the industry moves toward alternative fuels or slower steaming speeds to cut emissions, the cost structure shifts. Fuel becomes a larger share of the total, and fuel consumption does scale with weight, at least partially. You could see carriers experimenting with pricing models that blend volumetric and weight-based calculations differently than the current "greater of" approach.
The napkins-and-steel indifference might not hold forever.
Some carriers are already testing "cubic capacity only" pricing on certain lanes — where you pay purely for the space you occupy, regardless of weight, up to a safety limit. The logic is that it simplifies everything and aligns perfectly with the binding constraint. If the container fills before it sinks for ninety-five percent of cargo, why maintain the dual calculation at all?
That would be a fascinating shift. It would essentially make the volumetric system total rather than hybrid. Low-density shippers would see no change, but dense cargo shippers — the steel bearing people — might actually see costs drop, because they would no longer be cross-subsidized by the volumetric calculation that currently protects carriers on light loads.
Digital freight platforms like Freightos and Flexport are making all of this more transparent in real time. You can plug in dimensions and get instant LCL quotes that show you exactly how pallet standardization affects your rate. But the pallet question itself — the fact that the global system quietly runs on a European standard that most new operators have never heard of — remains a hidden friction point.
It is the kind of thing that does not show up in a Freightos quote until your supplier loads the wrong pallet and the surcharge hits. The platforms can make pricing transparent, but they cannot make the physical infrastructure standardize itself.
That is the open question I would leave listeners with. As e-commerce keeps growing and more small operators enter international freight, will the pallet standard finally converge globally the way the container did in the nineteen sixties? Or will we be stuck with this quiet mismatch forever, where the quoting system speaks Euro pallet and the warehouse floor speaks whatever is local?
If you found this useful, rate the show and tell a logistics friend. Thanks to Hilbert Flumingtop for producing. This has been My Weird Prompts. We are back next week.
Now: Hilbert's daily fun fact.
Hilbert: In the nineteen seventies, researchers studying octopus chromatophores in the Namib Desert discovered that a single square millimeter of octopus skin contains roughly two hundred thirty chromatophore organs — meaning a medium-sized octopus carries more individual color-control units across its body than the total number of pixels on the original Nintendo Entertainment System's entire screen output.
I have so many questions, none of which I will ask.
