Most articles on this question are written for importers. Exporters face a different set of constraints: your customer is waiting, your cut-off is set by a consolidation schedule you do not control, and your payment terms depend on the shipping document. Here is how the decision looks from the origin side.
The volume rule, and why it is only a starting point
A 20 foot container offers 28 to 30 cubic metres of usable space, a 40 foot 56 to 58. As a first pass, shipments above half a 20 foot box, 13 to 15 cubic metres, deserve a full container comparison. Below that, consolidation costs less in total. The reason is the pricing unit: LCL is charged on the greater of cubic metres or metric tons, so you pay for the space you use, and FCL is charged per box whether it is full or not. How the chargeable figure is built is in chargeable weight in ocean freight.
But volume alone does not decide it. Three other factors override the arithmetic.
Deadline
LCL runs on a fixed consolidation calendar. Cargo that misses the warehouse cut-off waits for the next departure. Our Miami LCL lanes are scheduled weekly, each with its own arrival weekday: Barbados arrivals fall on Wednesday, Antigua on Monday, Grenada on Thursday and St Lucia on Tuesday, so a missed cut-off pushes the arrival back by a week. FCL is booked against a sailing directly, so a late-running production run can still make the vessel until the container's own cut-off.
If your customer has a hard delivery date, or a letter of credit with a latest shipment date, the schedule risk of consolidation is a real cost. Missing a letter of credit shipment date creates a discrepancy, and discrepancies cost money or delay payment.
The export filing runs on the same clock
Every export by vessel needs its Electronic Export Information filed in the Automated Export System unless an exemption applies. The exporter or its agent gives the carrier the filing citation (the ITN) at least 24 hours before loading at the US port, and the carrier cannot load the cargo without it (19 CFR 192.14). The exemption under 15 CFR 30.37 covers commodities valued at $2,500 or less per Schedule B number from one exporter to one consignee on one conveyance. On LCL the filing is yours alone, because each shipper in the box is a separate exporter with its own filing, and the consolidator's cut-off sits before the vessel's. Used vehicles follow a longer rule, 72 hours before export (19 CFR 192.2). See commercial invoice requirements for the data the filing draws on.
Cargo risk
Consolidated cargo is handled at least twice more than a full container: once at origin during loading, once at destination during stripping. It is stacked next to freight you did not pack. For fragile, high value or awkwardly shaped goods, the seal on an FCL from your dock to your customer's door is worth paying for. If you do ship consolidated, the packing discipline in LCL container shipping is not optional.
Cash and inventory
FCL ties up more cash per shipment and reduces frequency. LCL lets you ship weekly, keeping your customer's stock lower and your receivables moving faster. In markets where your buyer's working capital is the constraint, and much of the Caribbean and Central America works that way, the ability to ship small and frequent is a commercial advantage rather than a freight compromise.
| Factor | Favours LCL | Favours FCL |
|---|---|---|
| Volume | Under half a container | Above half a container |
| Frequency | Weekly small orders | Monthly large orders |
| Cargo | Robust, palletised | Fragile, high value, oversized |
| Deadline | Flexible | Fixed date or L/C |
| Density | Light and bulky, if repacked well | Heavy and dense |
Dense cargo changes the answer
Heavy freight hits the container payload ceiling long before it fills the space. A 20 foot box can be full by weight while looking half empty, and road weight limits at destination can be stricter still. The limits are set out in container weight limits. For dense cargo the FCL crossover comes at a lower volume than the half-container rule: at 1,000 kg per cubic metre LCL is billed on weight, and cargo denser than that pays for weight instead of volume.
What a Miami LCL quote looks like
For a reference shipment of 5 cbm and 1,500 kg on FCA terms, our Miami LCL totals run from $635 to the Dominican Republic and $705 to Puerto Rico to $1,000 to Jamaica and $1,230 to Grand Cayman. The weight is 1.5 tons, so volume governs and the chargeable figure is 5.
| Miami to | Total for 5 cbm / 1,500 kg | Transit |
|---|---|---|
| Dominican Republic | $635 | 3 days |
| Puerto Rico | $705 | 3 days |
| Barbados | $795 | 6 days |
| Trinidad | $985 | 8 days |
| Jamaica | $1,000 | 4 days |
| Grand Cayman | $1,230 | 5 days |
Ask for the FCL price to the same port on the same scope and compare it with this total at your actual cubic metres. If the two are close, the factors above decide: deadline, cargo risk and cash. Our destination guides for the Dominican Republic and Jamaica show what each lane adds on arrival, and shipping from Miami to Latin America covers the origin side.
Documents differ by option
On FCL the carrier issues the bill of lading to you as shipper. On LCL the ocean carrier issues the master bill to the consolidator, and the consolidator, acting as an NVOCC, issues a house bill to you. A letter of credit that calls for a specific type of bill therefore needs the consolidator's house bill to be acceptable to the bank before you book. An NVOCC that transmits its own cargo declaration to CBP has to be licensed by or registered with the Federal Maritime Commission and hold an International Carrier Bond (19 CFR 4.7(b)(3)), and the FMC requires $75,000 of financial responsibility from an NVOCC operating in the United States (46 CFR 515.21). Ask the consolidator for its FMC license number before you book. Bill of lading types explains the options.
What the export filing asks for
The data in the Electronic Export Information comes from your invoice and packing list. Under 15 CFR 30.6 it includes the shipping weight in kilograms, which is the commodity plus normal packaging, and, for containerized vessel cargo, the container number and seal number. The transportation data adds the method of transport, the carrier's four-character SCAC, the conveyance name (the vessel), the country of ultimate destination, the date of export and the port of export (19 CFR 192.14(c)). The port and date have to match the booking: if the carrier exports from a different port, the filer corrects the port in AES. Collect the booking details from the forwarder before filing, not after. The packing list side is in packing list requirements.
Cargo that closes the choice
- Dangerous goods. Segregation rules apply to every combination of materials in the box, and many consolidators refuse certain classes. The booking has to declare the hazard. See dangerous goods by ocean.
- Used vehicles. CBP needs the vehicle and its title documents 72 hours before export (19 CFR 192.2) for vessel exports. A vehicle that is driven aboard is a roro shipment, and one that is loaded into a box needs its documents cleared first. See breakbulk vs container shipping.
- Wood packaging. Pallets and crates need the treatment mark the destination requires, and in a consolidated box that applies to every shipper's cargo. See ISPM 15 wood packaging requirements.
The practical test
Price both, on the same scope, for your actual shipment. Add the destination charges to each. Then ask two questions: what happens if this misses the cut-off, and what happens if a carton is damaged. The answers decide it faster than the price difference.
Our FCL and LCL services quote the same shipment both ways so the comparison is like for like.
FAQ
At what volume should I switch from LCL to FCL?
Ask for both quotes from 13 to 15 cubic metres, half of a 20 foot container's 28 to 30 cubic metres. Dense cargo crosses over sooner, because weight rather than volume sets the LCL charge above 1,000 kg per cubic metre.
Is FCL always faster?
FCL skips consolidation and deconsolidation, so it removes the warehouse time at both ends. The ocean leg itself is identical.
Can I split one order across LCL and FCL?
You can, but you pay two sets of fixed charges, file two export filings and manage two arrivals. It does not pay below a full container.
Does LCL cost more per cubic metre?
LCL carries the consolidator's handling and documentation charges per shipment, and a full container is priced per box whatever its fill, so the LCL unit price climbs against the FCL box as volume grows. The saving is on the total at small volumes, not on the unit.
Which is better for a letter of credit shipment?
FCL is easier to control against a latest shipment date. If you use LCL, build the consolidation cut-off into your production schedule.
What export filing does each option need?
Both need the Electronic Export Information filed in AES, with the ITN given to the carrier at least 24 hours before loading, unless the commodity value per Schedule B number is $2,500 or less. On LCL each shipper files its own.
How does density change the LCL charge?
At 1,000 kg per cubic metre the weight and volume figures are equal. A 12 cbm shipment weighing 2,400 kg is billed on 12, and the same 12 cbm weighing 15,000 kg is billed on 15, so the heavier load is the one to quote as FCL first.
Does the consolidator need an FMC license?
To file its own cargo declaration with CBP, an NVOCC has to be licensed by or registered with the FMC and hold an International Carrier Bond. The FMC sets the NVOCC's financial responsibility at $75,000 for a US operator under 46 CFR 515.21, and you can ask for the license number at booking.
