Two shipments with the same weight, on the same sailing, are invoiced differently. LCL pricing rewards dense, well packed, well timed cargo and charges more for everything else. These are the levers, in the order they matter.
1. Density decides the base
LCL is charged on weight or measure, whichever is greater: one cubic meter against one metric ton, and the higher figure wins. Cargo lighter than that ratio pays for the space it occupies and not for what it weighs.
| Shipment | Volume | Weight | Chargeable revenue tonnes | Which one wins |
|---|---|---|---|---|
| Light retail goods | 5 CBM | 1,500 kg (1.5 t) | 5 | Measure |
| Mixed hardware | 3 CBM | 3,000 kg (3 t) | 3 | Equal, weight and measure tie |
| Tiles on pallets | 2 CBM | 4,000 kg (4 t) | 4 | Weight |
The consequence: air inside your packaging is billable. Oversized cartons, half empty pallets and packaging designed for retail display and not for transport convert directly into freight cost. Reworking a pallet configuration is the cheapest saving available on this mode, and it needs no negotiation with anyone. The calculation is in chargeable weight in ocean freight.
2. Handling at both ends
LCL involves a container freight station at origin and another at destination. Those handling charges are per cubic meter or per shipment, as the tariff states. They are unavoidable, and their weight in the total is higher on small shipments. A one cubic meter shipment pays fixed handling and documentation that can exceed its ocean freight.
That is why very small LCL shipments cost more per unit, and why grouping two weeks of orders into one shipment lands cheaper than shipping weekly. The glossary entries for container freight station and consolidation fee define the two lines. The terminal handling charge is the third fixed line, apportioned across the container.
The port pair moves the price
The Interworld Freight published LCL rates for a 5 CBM and 1,500 kg load, quoted FCA Miami (rates refreshed 2026-07-21 in the schedule), show how much the destination changes the invoice for the same cargo:
| Miami to | Total for 5 CBM / 1,500 kg | Per CBM |
|---|---|---|
| Dominican Republic | $635 | $127 |
| Puerto Rico | $705 | $141 |
| Barbados | $795 | $159 |
| Jamaica | $1,000 | $200 |
| Grand Cayman | $1,230 | $246 |
The rates exclude destination duties, taxes and local charges. The same load costs 1.9 times as much to Grand Cayman than to the Dominican Republic ($1,230 against $635), and the per-CBM figure is the total divided by 5. Compare destinations on the all-in total for your own volume.
3. Destination charges
The charges after arrival are the ones missing from most comparisons: deconsolidation, delivery order, terminal handling, storage after the free period. On lanes with thin destination capacity, destination charges exceed the ocean freight. Ask for them at quote stage, and read how to compare ocean freight quotes before you accept a number that looks unusually low.
Storage after free time is regulated on the US side. For demurrage and detention charges, the billing party must issue the invoice within 30 calendar days from the date the charge was last incurred, or the billed party owes nothing, and the invoice must show the bill of lading number, the container number, the free time and the daily rate (46 CFR part 541).
4. Timing
Booking against the cut-off costs more than booking with notice, and peak weeks price above shoulder weeks. On lanes with weekly consolidations, cargo that arrives at the warehouse a day late waits a full week, which turns a freight saving into a stock problem. In the Interworld Freight schedule, cargo to Barbados arrives on Wednesdays and cargo to Saint Lucia (Castries) on Tuesdays, so the consolidation week is fixed by the destination.
For US-bound cargo, the cargo declaration and the first ISF elements are due 24 hours before the cargo is loaded at the foreign port (19 CFR 4.7 and 149.2), so late paperwork is a missed sailing, and a missed sailing waits for the next consolidation. The ISF guide lists the elements.
5. Incoterm and control
If your supplier controls the freight under a C or D term, you inherit their forwarder's origin charges and lose visibility of what they cost. Buying on FOB or FCA and controlling the main leg yourself is the structural version of this saving, and it matters more than any rate negotiation.
What does not save money
Understating dimensions. The consolidator remeasures at the warehouse and bills what it finds, and the amended figures land after the cargo has sailed. Splitting one shipment into several to stay under a threshold multiplies fixed charges. And choosing the cheapest quote without checking the destination side moves the cost to a later invoice.
When to stop optimizing and switch to FCL
Once you reach half a container, price both. A 20 foot container holds 28 to 30 cubic meters of usable space, so a comparison starts at 14 cubic meters, and dense cargo crosses over sooner. FCL also removes two handling points, which matters for fragile goods. The comparison is in LCL vs FCL for US exports.
Packing for the chargeable quantity
The packing decision is the only lever you hold before the booking. Five changes cut billable volume without touching the product:
- Size cartons to the pallet footprint. A carton that overhangs the pallet adds volume the stack does not use. The standard pallet sizes entry lists the footprints.
- Stack to a stable height. A pallet that is full to the maximum stable height carries more product per billable cubic meter than a half-built pallet.
- Remove retail display packaging for transit. Ship the product in master cartons and apply the display packaging at destination.
- Fill voids. Fill the gap inside a carton, because the carton is measured and the gap is billed.
- Declare each handling unit once. The packing list, the invoice and the booking show the same count, dimensions and weight.
The packing list is the document the consolidator measures against, so its figures are the base for any later remeasure charge. See packing list requirements.
A worked example of the fixed and variable split
Write the invoice as two parts. The variable part is the per-CBM rate multiplied by the revenue tonnes. The fixed part is documentation, the origin and destination handling minimums and the terminal handling minimum. The cost per CBM equals the variable rate plus the fixed part divided by the CBM.
| Shipment volume | Fixed part per CBM | Variable part per CBM |
|---|---|---|
| 1 CBM | $F | Rate |
| 2 CBM | $F divided by 2 | Rate |
| 4 CBM | $F divided by 4 | Rate |
| 8 CBM | $F divided by 8 | Rate |
The table uses a fixed part of $F and shows only the fixed share per CBM, so the pattern is visible without inventing a tariff. The fixed share per CBM falls by half each time the volume doubles. A shipper that moves from 1 CBM to 4 CBM cuts the fixed share per CBM to a quarter, with the same fixed part, and the variable rate stays the same.
China-origin quotes in the same schedule
The same schedule quotes the 5 CBM and 1,500 kg load from China through Miami. To the Dominican Republic the quote is $2,140 from Shanghai and $2,175 from Shenzhen, and to Jamaica it is $2,550 from Shanghai and $2,585 from Shenzhen. The $35 difference between the two origins is the same on both lanes, and the transit differs by 17 days (Shanghai 18 days to Miami against 35 for Shenzhen). A rate comparison without the transit days leaves out the larger part of the difference. The lane guides LCL shipping from China to the Dominican Republic and China to Caribbean shipping cost break the quotes down.
A line-by-line invoice audit
- Chargeable quantity: compare the invoiced revenue tonnes with your own volume and weight. A remeasured figure above your packing list means the cartons were larger than declared.
- Ocean rate: multiply the per-CBM or per-ton rate by the chargeable quantity and confirm the total.
- Origin lines: CFS handling, consolidation, documentation and origin terminal handling.
- Destination lines: deconsolidation, delivery order, terminal handling and delivery.
- Surcharges: each one named, with its tariff date.
- Minimums: any line billed at a minimum charge instead of the per-CBM calculation.
US rules back the audit. An NVOCC that passes through a carrier's surcharges lists the named charges in its tariff and must not mark them up above cost, and the rates that apply are those in effect on the date the carrier or its agent receives the cargo (46 CFR 520.7).
FAQ
How is LCL priced?
On weight or measure, whichever is greater, plus origin and destination handling, documentation and terminal charges.
Why is my small shipment so expensive per cubic meter?
Fixed charges do not shrink with the shipment. Documentation, handling and minimums are the same for one cubic meter as for five.
Can I reduce cost by repacking?
Yes. Removing void space lowers the chargeable volume, and on light cargo that is a direct saving.
Is LCL cheaper than air freight?
LCL costs less per kilo, and it takes longer. For urgent, light and high value cargo, air can be the cheaper total once inventory cost is counted.
Do LCL rates include destination delivery?
Only when the quote says so. Ask specifically whether delivery from the destination warehouse is included.
Where do I find the chargeable quantity on my invoice?
On the line for ocean freight, stated in revenue tonnes or in CBM. If it is higher than the volume on your packing list, the consolidator remeasured the cargo at the warehouse, and the invoice shows the remeasured figure.
What is a revenue tonne?
The chargeable unit in LCL: the greater of the volume in cubic meters and the weight in metric tons. A 5 CBM shipment weighing 1.5 t is 5 revenue tonnes, and a 2 CBM shipment weighing 4 t is 4 revenue tonnes.
Why does the same 5 CBM load cost different amounts to different islands?
The port pair sets the origin handling, the ocean leg, the destination handling and the local charges. In the Interworld Freight schedule, the same 5 CBM and 1,500 kg load from Miami is $635 to the Dominican Republic and $1,230 to Grand Cayman.
