Your China order is already bigger than a parcel, but it may not fill a container — and that is exactly where a decision that costs real money begins: ship it as consolidated cargo (LCL) or book a full container (FCL). This guide is for the B2B importer sitting in that decision zone: a shipment of a few cubic metres or a handful of pallets, where one wrong call adds hundreds of dollars to the cost of every cubic metre. Retail parcels are not the subject here. Below is where the line falls, how to calculate it for your own rates, and when jumping to a container pays off.
In short. LCL (less-than-container-load) means your freight rides in a shared container and you pay only for the space you occupy. FCL (full container load) means you rent the whole container at a flat rate regardless of how full it is. LCL wins at low volume but has a "hidden" billing method; FCL is cheaper per cubic metre the moment you approach 13–15 CBM. The precise line is set by the ratio of your own rates, not a universal number.
What LCL is and how it is actually billed
LCL is consolidated cargo. Several shippers share one container, and your goods are consolidated and deconsolidated at container freight stations (CFS) in the origin and destination ports. You pay in proportion to the space you use, so the entry threshold is low — the main advantage for test runs and small batches.
The LCL trap is in the billing. The rate is not simply "per cubic metre" but follows the W/M rule (weight or measurement, whichever is greater). One "revenue ton" equals either 1 CBM or 1,000 kg, and the carrier bills you on whichever figure comes out larger.
For dense freight — metal, fasteners, tiles, machinery — you pay by weight, not volume, and LCL climbs faster than a cubic-metre calculator suggests.
For ordinary consumer goods at 200–500 kg/m³, volume almost always wins and you are billed on CBM. But as density nears 1,000 kg/m³, the weight side of the rule kicks in. The W/M logic is explained in detail by the industry reference CalculateCBM. This is one reason a container becomes the cheaper option earlier for heavy categories.
What FCL is and why it is cheaper per cubic metre
FCL is a full container dedicated to your order. You pay a flat rate per container (20', 40', 40'HQ) regardless of actual load. The more you put in, the cheaper each cubic metre becomes — which is why FCL always catches up to LCL as volume grows.
Beyond the price per cube, FCL delivers three things that matter at container scale:
- The container is sealed at the factory and not opened until your warehouse — fewer handling points, less risk of damage and mix-ups.
- Simpler documentation: one bill of lading for one shipper, with no third-party cargo in the same box.
- Faster movement: no CFS consolidation and deconsolidation, the steps that add days to LCL.
Cost comparison and the CBM break-even point
This is the number the whole exercise is about. Historically the LCL→FCL crossover sits in the 13–15 CBM range (as of 2026, verify current rates on your own lane — in practice it runs from 12 to 18 CBM depending on the carrier and local charges).
Do not rely on someone else's figure — calculate it from your own rates, and the formula is simple:
- Break-even (CBM) ≈ flat 20' FCL rate ÷ LCL rate per CBM.
- Example: a 20' FCL costs $1,400 and LCL is $100 per CBM. Break-even = 14 CBM. Below it, LCL; above it, a 20' container.
- At 12–15 CBM, always pull both quotes side by side: the gap is small and local charges can tip the balance.
- For dense freight the W/M rule shifts the line: billed by weight, LCL grows more expensive and the container pays off sooner.
One factor stays out of sight: the decision is made on total landed cost, not freight alone — port charges, deconsolidation and delivery to your warehouse included. LCL carries more small fixed fees per shipment, and near the break-even line those are often what decides the outcome. For a method to roll every cost into one figure, see our breakdown of landed cost for China imports.
Transit time and damage risk
Volume is not the only axis. LCL is almost always slower: your cargo waits to be consolidated with others at the origin CFS, then goes through deconsolidation at destination before release. Those two steps add days — sometimes a week — to transit compared with FCL, where a sealed container moves door to door.
Damage risk in LCL is also higher, not because the cargo is handled carelessly but because it is physically transferred more times and stands beside strangers' boxes. A heavy neighbour, moisture, a mislabelled pallet at the consolidation warehouse — all statistically more common with shared shipments. For fragile or high-value goods, that argues for FCL even slightly before the formal break-even point.
When LCL wins and when it is time for a container
LCL is the right call when:
- volume is consistently below ~13–15 CBM and the cargo is not dense;
- you are testing a new supplier or a new product in a small batch;
- flexibility and a low entry threshold matter more than speed;
- you have several small orders from different factories worth consolidating into one shipment.
Switch to FCL when:
- volume is steadily 15+ CBM — per cubic metre the container is already cheaper;
- the cargo is dense or heavy and the W/M rule hits your wallet;
- goods are fragile, valuable or sensitive to handling;
- schedule and predictability are critical to you;
- you ship regularly — then even a half-full container often beats the sum of LCL fees.
A practical rule: if you consistently move 15+ CBM, stop asking "what does my shipment cost" and ask "what does it cost to fill a container" — then size the order to the container rather than the other way around. For packing dense freight tightly so you are not paying for air, see our worked example of calculating container loading for steel.
Container capacity reference
Working benchmarks for usable volume (as of 2026; the real figure depends on packing, palletisation and whether the cargo stacks):
- 20' GP — theoretically up to ~33 CBM, realistically ~25–28 CBM of carton cargo; payload ~28 tonnes.
- 40' GP — theoretically ~67 CBM, realistically ~55–58 CBM.
- 40' HQ (high cube, about 30 cm taller) — theoretically ~76 CBM, realistically ~62–68 CBM.
Note: you will never fill the "theoretical" volume — there are always voids between boxes, and dense freight hits the weight limit long before the volume limit. Plan to the working range.

Let us calculate LCL vs FCL for your volume
Choosing between consolidated cargo and a container is not a matter of taste but the arithmetic of your rates, cargo density and timelines. Over 7 years (since 2019) we have run more than 3,500 business deliveries, so we know exactly where the real break-even line falls on your lane.
Send us the shipment spec — volume in CBM, weight and product category — and as a full-cycle partner (sourcing → supplier verification → production → quality control → sea freight → customs) we will price both scenarios and show which is cheaper for you, landed at your destination.
