All Shipping Modes guides
Oversize Load Permits and Pilot Cars Explained
There is no national oversize load permit in the United States. Every state sets its own dimension thresholds, its own escort requirements, and its own process, and a coast-to-coast heavy haul means a separate application to nearly every one of them. Here is how the system actually works.
LTL Freight Class and NMFC Explained
Freight class decides what an LTL shipment costs, and it is set by a private industry standard, not a government rule. Since July 2025 most commodities are classed by measured density rather than a fixed lookup, and the system is still being rewritten: a public comment period on the next round of changes closes in days.
Vessel Sharing Agreements and Slot Chartering Explained
Alliance news tells you who is partnering with whom. It rarely explains the mechanism: how carriers legally pool vessels, why a filed agreement gets antitrust immunity, and why the carrier on your bill of lading may not be the one that operated the ship. That last point decides where a cargo claim actually goes.
RoRo vs Container Shipping for Vehicles and Machinery
RoRo and container shipping are priced differently, measured differently and regulated differently, and the choice is usually decided by height, weight and rating basis rather than by preference. Here are the real deck and door numbers, what the 2026 fire safety and dangerous goods rules actually changed, and the export and import compliance that catches vehicle shippers out.
Air Freight ULD Types: Which Unit Load Device Fits Your Cargo
Air cargo is built up on unit load devices before it ever reaches the aircraft. Choosing or accepting the wrong ULD type wastes chargeable space and can hold a shipment off a flight entirely.
Breakbulk and Project Cargo: When Your Freight Does Not Fit a Container
Breakbulk and project cargo cover the freight that containers were never designed for: oversized, overweight, or awkwardly shaped loads that need their own stowage plan, not a booking reference.
Stretch Wrap, Strapping and Getting a Pallet to Arrive Intact
Most pallets fail the same way: the film never gripped the pallet, so the load slides off the base as one piece. Thickness is not the measure that matters.
Shipper-Owned vs Carrier-Owned Containers (SOC vs COC)
A shipper-owned container stops the detention clock permanently. It also makes the empty your problem, which is the whole calculation.
Pre-Cooling and Loading a Reefer Without Breaking the Chain
The chain usually breaks in the twenty minutes the doors are open. Loading a reefer properly is a sequence, and one step of it is the opposite of intuition.
Marine Pollutants and UN Numbers: Getting Classification Right
Marine pollutant status is an extra label on top of whatever your cargo already is. Plenty of ordinary products qualify, including detergents and paints.
Shipping Fresh Produce: Controlled Atmosphere and Ethylene
Fresh produce is alive in the container. It breathes, it gives off heat and ethylene, and several popular fruits are ruined by being kept too cold.
Limited and Excepted Quantities: When Full DG Rules Do Not Apply
Small quantities in small inner packagings pose less risk, and the regulations recognise it. Two separate regimes exist and they are frequently confused.
High Cube vs Standard: When the Extra Foot Helps
The extra foot of height is nearly free at sea and occasionally impossible on the road. Whether it helps depends on your cargo height and your destination.
Export Crating: When a Box Is Not Enough
Machinery and capital equipment need structure, not cardboard. Crating is also where corrosion protection, desiccant and shock indicators come in.
Segregation and Stowage of Dangerous Goods at Sea
Two containers that are each perfectly safe can be a serious hazard side by side. Segregation is why a dangerous goods booking takes longer and costs more.
Container Damage, Detention and Per Diem: Who Pays
The container is not yours. You are borrowing it, and the charges for holding it or returning it damaged are separate from the freight you agreed.
Cargo Marking and Labelling: What Goes on the Outside
The outside of the box is a document. It routes the cargo, tells handlers how to treat it, and in some cases is a customs requirement in its own right.
Active vs Passive Cold Chain Packaging for Air Freight
A powered container and an insulated box solve the same problem differently. The choice turns on duration, value, volume and how much handling risk you can absorb.
Reefer, Flat Rack, Open Top and Tank: Special Equipment
Special equipment is scarcer, dearer and slower to position than a standard box. Here is what each type is actually for and when a standard container will do.
Shipping Lithium Batteries by Air and Sea in 2026
Lithium batteries are the most heavily regulated everyday cargo in freight, and the rules changed on 1 January 2026 for batteries shipped inside equipment.
Pallet Sizes Around the World and How They Fit a Container
A container floor is 2.35m wide, and no common pallet divides into it neatly. Which pallet you use decides how much of the box you actually pay to ship as air.
GDP Pharma Shipping: What the Rules Actually Require
GDP is about documented control, not about how cold the box was. Most forwarders who say they are GDP compliant cannot produce what compliance actually requires.
Dunnage, Lashing and Bracing: Securing Cargo for Sea
Cargo at sea is not sitting still. It is being accelerated in three axes for weeks, and restraint has to be designed for that, not for the drive to the port.
The Dangerous Goods Declaration: How to Get It Right
Most dangerous goods declarations are refused for the order of words in the shipping name, not for anything about the cargo. Here is how to complete one properly.
Container Weight Limits, Payload and VGM
A container can legally hold far more than a truck can legally carry it. Loading to the plate figure is how shipments become undeliverable by road.
Cold Chain Data Loggers and Temperature Excursions
An excursion is not automatically a loss. The damage is usually done by whoever decides on the spot to write the shipment off, or to accept it without telling anyone.
Reefer Setpoints, Ventilation and Humidity: What to Specify
Most reefer claims trace back to three lines on a booking that nobody filled in properly. Here is what each setting does and what happens when it is wrong.
ISPM 15: Wood Packaging Rules and Why Shipments Get Rejected
The pallet under your cargo is regulated cargo in its own right. Untreated wood gets shipments refused entry, and the piece that fails is usually not the pallet.
The 9 Dangerous Goods Classes, With Everyday Examples
Most dangerous goods problems start with a shipper who did not know their product was regulated. Here are the nine classes and the everyday goods that fall into them.
How to Read a Container Number and CSC Plate
The eleven characters on the side of a container are a checkable code, not a serial number. Here is how to verify one yourself and what the safety plate on the door means.
Cargo Securing Inside the Container: The Step Most Shippers Skip
Packing a container is not stacking boxes: weight distribution, void filling and lashing decide whether cargo arrives intact or becomes a claim.

Shipping Modes FAQ
Should I ship by air or by sea?
Choose sea for cost and air for speed. Ocean freight is dramatically cheaper per kilogram and suits bulky, heavy, or non-urgent cargo, with transits typically measured in weeks. Air freight is far more expensive but moves in days, and it makes sense for high-value, perishable, or time-critical goods, and sometimes for lower-value cargo when the inventory cost of a long sea transit outweighs the freight saving.
When should I use FCL instead of LCL?
FCL usually becomes the better choice somewhere around 13 to 15 cubic metres, though the exact crossover depends on the lane and current rates. Below that, LCL costs less because you pay only for the space used. Above it, a full container is often cheaper outright, and it is also faster and lower-risk, because the container is sealed at origin and not opened until destination.
Why does LCL take longer than FCL?
Because LCL cargo has to be consolidated and deconsolidated. At origin the consolidator waits to fill a container with other shippers' cargo before it sails; at destination the container is stripped and each consignment sorted before release. Those two processes commonly add several days at each end, on top of the ocean transit itself.
What is transshipment and does it affect my delivery date?
Transshipment is transferring cargo from one vessel to another at an intermediate hub port, and yes, it adds risk to your delivery date. Each transfer is a point where the container can miss its connection, and a missed connection typically costs a week waiting for the next sailing. Direct services cost more but are more predictable, and worth paying for when the date is tight.
What is a reefer container and when do I need one?
A reefer is a refrigerated container with its own cooling unit, needed for any cargo with a temperature specification, such as food, pharmaceuticals, some chemicals and cosmetics. It requires a monitored power supply at every stage, including in port and on the road, and you must state the temperature set point and any pre-cooling requirement at booking rather than assuming a default.
What can I do if my cargo is too big for a standard container?
Use a flat rack, an open top, or breakbulk depending on the dimensions. Open tops suit cargo that is too tall to load through the doors but stays within the container profile; flat racks handle loads that exceed the width or height envelope; genuinely oversized pieces move as breakbulk or project cargo. Anything protruding beyond the container envelope is rated out of gauge and charged for the vessel slots it blocks.
What does it mean if my container is rolled?
It means your container was booked and delivered for a sailing but not loaded, and has been carried forward to a later vessel. Common causes are carrier overbooking, vessel weight limits, a blank sailing, or documentation such as the VGM not being filed by cut-off. Cargo booked on the cheapest spot rates is generally rolled first.
