What Does “In Transit” Mean in Freight Shipping?

Quick Overview

“In transit” means a shipment has entered the carrier’s transportation network and is progressing toward its destination. It does not necessarily mean the cargo is moving at that exact moment. It may be on a vessel, aircraft, truck or train, or waiting at a port, airport, terminal or transfer facility.

What Does “In Transit” Mean?

In freight shipping, in transit means that the carrier has accepted the cargo and the shipment has not yet reached its final delivery point.

The status can cover several stages of an international shipment, including:

• Moving from the supplier to the origin port or airport
• Waiting for vessel or flight departure
• Traveling by ocean, air, road or rail
• Passing through a transshipment hub
• Waiting at a terminal between transport legs
• Arriving at the destination port or airport
• Undergoing customs clearance
• Moving from the terminal to the final delivery address

An in-transit status does not confirm that the shipment is physically moving at every moment. It may remain unchanged while the cargo waits for a scheduled departure, connection, customs release or delivery appointment.

Does “In Transit” Mean the Shipment Is Moving?

Not always.

“In transit” is a broad tracking status covering the period between carrier acceptance and final delivery.

The shipment may currently be:

• On board a container ship
• Loaded onto an aircraft
• Moving by truck or rail
• Waiting at an origin warehouse
• Stored temporarily at a port terminal
• Waiting for a connecting vessel or flight
• Under customs review
• Awaiting final-mile collection
• Waiting for a delivery appointment

For example, an ocean container may show as in transit throughout a 20-day voyage, even though no new tracking scan is created while the vessel is at sea.

In-Transit Status by Freight Mode

Ocean Freight

For ocean freight, in transit can mean that the container:

• Has been collected from the shipper
• Has entered the port terminal
• Is waiting to be loaded
• Has been loaded onto the vessel
• Is traveling to a transshipment port
• Is waiting for a connecting vessel
• Has arrived at the destination port
• Is waiting for customs or terminal release
• Is moving by truck or rail to the consignee

Ocean freight can remain in transit for several weeks because of long sailing distances and limited tracking events while the vessel is at sea.

Air Freight

For air freight, in transit may mean that the shipment:

• Has been accepted by the airline
• Is waiting at the origin airport
• Has been loaded onto a flight
• Is traveling to a connecting airport
• Is waiting for a transfer
• Has arrived at the destination airport
• Is undergoing customs clearance
• Is moving to the final delivery address

Air cargo usually has more frequent tracking events than ocean freight, but the status may remain unchanged while the goods wait for a scheduled connecting flight.

Road Freight

For road freight, the status usually means the cargo has been collected and is moving through the carrier’s network.

It may be:

• On a long-haul truck
• At a freight terminal
• Being transferred between vehicles
• Waiting for a driver
• Held at a border crossing
• Awaiting delivery scheduling

Rail Freight

Rail cargo may remain in transit while it is:

• Traveling between rail terminals
• Waiting for a train departure
• Transferring between rail services
• Undergoing border or customs processing
• Waiting for truck collection at the destination terminal

Common Freight Tracking Statuses

Tracking terminology varies between shipping lines, airlines, freight forwarders and courier companies. The detailed event history is often more useful than the main status label.

“In Transit” Versus “Out for Delivery”

These statuses describe different stages.

A container traveling from Shanghai to Los Angeles is in transit.

After customs release and terminal collection, the container may remain in transit while it is trucked to the importer’s warehouse.

The status changes to out for delivery only when the shipment enters the final delivery stage, if the carrier uses that tracking label.

“In Transit” Versus “Customs Clearance”

A shipment can be in transit and under customs review at the same time.

Customs clearance is a specific process involving:

• Import documentation
• Tariff classification
• Customs valuation
• Duties and taxes
• Product permits
• Security screening
• Physical or documentary inspections

The cargo may have reached the destination country but continue to show as in transit until customs releases it and the carrier completes delivery.

Review the customs clearance and duties guide before the shipment reaches its destination.

“In Transit” Versus “Transshipment”

A transshipment occurs when cargo is transferred from one vessel, aircraft or transport service to another before reaching its final destination.

For example:

1. A container leaves Shanghai.
2. It arrives at Singapore.
3. It is unloaded from the first vessel.
4. It waits at the transshipment terminal.
5. It is loaded onto a second vessel.
6. It continues to New York.

The shipment remains in transit throughout this process.

Transshipment can increase the total transit time because the cargo must wait for the connecting service.

How Long Can a Shipment Remain In Transit?

The duration depends on the freight mode, route, carrier and final destination.

These are general planning ranges rather than guaranteed delivery times.

Use the transit time calculator to estimate the main transportation stage for a specific route.

Why Has the Tracking Status Not Changed?

A shipment can continue moving even when its tracking page has not been updated.

Common reasons include:

The Vessel Is at Sea

Ocean containers are not scanned continuously during a voyage. The status may remain unchanged until the vessel reaches the next port.

The Next Tracking Event Has Not Occurred

Tracking systems are normally updated when a specific operational milestone occurs, such as:

• Terminal entry
• Vessel loading
• Vessel departure
• Port arrival
• Container discharge
• Customs release
• Terminal pickup
• Delivery

There may be several days between these milestones.

Data Has Not Synchronized

The carrier, terminal, customs broker and freight forwarder may operate different systems. An event can occur before it appears on the customer-facing tracking page.

The Shipment Is Waiting for a Connection

A container or airfreight shipment may wait at a transshipment hub until the next vessel or flight becomes available.

Customs Is Reviewing the Shipment

Customs review can take place without an immediate change to the main carrier status.

Weekends or Public Holidays

Port terminals, customs offices, warehouses and trucking companies may operate with reduced hours during weekends and holidays.

Why Is an In-Transit Shipment Delayed?

Port Congestion

High vessel volumes, full container yards and limited truck or rail capacity can delay cargo movement.

Check the current port congestion report when the shipment is approaching a busy gateway.

Weather

Storms, fog, high winds, flooding and extreme conditions can delay vessels, flights, trucks and terminal operations.

Customs Inspections

Customs or another government agency may request:

• Additional documentation
• Product permits
• Value verification
• Cargo examination
• Laboratory testing
• Proof of origin

Missing or Incorrect Documents

Problems with the commercial invoice, packing list, Bill of Lading or product classification can delay clearance.

Review the shipping documents guide before departure.

Carrier Schedule Changes

Shipping lines may change schedules because of:

• Blank sailings
• Port omissions
• Vessel delays
• Equipment shortages
• Network changes
• Geopolitical disruption

Missed Connections

A late vessel or aircraft may cause the cargo to miss its planned connecting service.

Trucking or Rail Delays

Even after port arrival, cargo may wait because of:

• Truck appointment shortages
• Chassis shortages
• Rail backlogs
• Warehouse availability
• Driver shortages
• Road congestion

When Should You Be Concerned?

An in-transit status is normally not a problem when:

• The shipment remains within its estimated transit time.
• The vessel or flight is still following its route.
• No exception or delay notice has been issued.
• The estimated arrival date has not passed.
• The freight forwarder can confirm the current milestone.

You should investigate when:

• The estimated arrival date has passed.
• Tracking has not updated after the expected port or airport arrival.
• The shipment has missed a connection.
• The carrier reports an exception.
• Customs has requested information.
• The container has been discharged but not released.
• Free time is approaching its expiration.
• The cargo is urgent or production-critical.

What Should You Do When Freight Is Stuck In Transit?

1. Review the Full Tracking History

Check the detailed events rather than relying only on the main “in transit” label.

Identify:

• Last confirmed location
• Last tracking event
• Vessel or flight number
• Estimated arrival
• Transshipment port
• Customs status
• Delivery status

2. Confirm the Vessel or Flight Schedule

For ocean freight, check whether the vessel:

• Departed on schedule
• Changed its estimated arrival
• Omitted a port
• Is waiting outside the port
• Has arrived but not berthed

3. Contact the Freight Forwarder

The freight forwarder may have access to carrier, terminal and customs information that is not displayed in public tracking.

Provide:

• Booking number
• Bill of Lading number
• Container number
• Air Waybill number
• Purchase-order reference
• Consignee information

4. Check Customs Status

Confirm whether customs or another government agency is waiting for:

• An invoice
• Classification information
• Importer details
• Payment
• A permit
• A certificate
• An inspection

5. Prepare for Arrival

Do not wait until the status changes to “arrived” before arranging:

• Customs clearance
• Payment of destination charges
• Trucking
• Warehouse appointments
• Container unloading
• Empty-container return

6. Monitor Free Time

Once a container is discharged, terminal storage, demurrage or detention exposure may begin.

Review the guide to demurrage, detention and per diem fees to understand the possible charges.

Can an In-Transit Shipment Be Delivered Late?

Yes.

“In transit” describes the shipment’s current stage but does not guarantee on-time delivery.

The estimated delivery date can change because of:

• Weather
• Congestion
• Customs clearance
• Port closures
• Missed connections
• Carrier schedule changes
• Inland transportation delays
• Incorrect documents

Estimated transit times should therefore be treated as planning information rather than guaranteed delivery commitments unless the transport contract provides a specific guarantee.

Does In Transit Include Customs Clearance?

It can.

Some tracking systems continue to show the cargo as in transit while customs clearance is underway. Others use a separate status such as:

• Customs clearance started
• Clearance delay
• Customs hold
• Entry submitted
• Customs released

A shipment is not ready for final delivery until customs and any other relevant government agencies have released it.

Does In Transit Mean the Cargo Has Left the Origin?

Usually, but not always.

Some carriers may apply the status after cargo collection, even when the shipment is still waiting at an origin warehouse, port or airport.

Check the detailed milestone for confirmation.

Events such as departed origin, vessel departed, flight departed or loaded on board provide stronger evidence that the main international transport leg has started.

Can the Delivery Address Be Changed While In Transit?

It may be possible, but changes depend on:

• Freight mode
• Carrier rules
• Customs documentation
• Bill of Lading type
• Current shipment location
• New destination
• Additional cost
• Required authorization

Changing the destination of an ocean shipment may require:

• Carrier approval
• Bill of Lading amendment
• Manifest correction
• Customs notification
• New freight charges
• Additional transit time

Request any change as early as possible.

How to Track an International Freight Shipment

Freight shipments are commonly tracked using:

• Container number
• Bill of Lading number
• Booking number
• Air Waybill number
• PRO number
• Purchase-order reference
• Carrier tracking number

Use iContainers Track & Trace to follow available ocean and air shipment milestones.

Tracking events may include:

• Booking confirmed
• Cargo collected
• Container gated in
• Vessel departed
• Transshipment
• Vessel arrived
• Container discharged
• Customs released
• Cargo available
• Final delivery

How to Reduce In-Transit Delays

Choose the Appropriate Freight Mode

Use:

• FCL shipping for larger containerized shipments.
• LCL shipping for smaller palletized cargo.
• Air freight for urgent or high-value goods.

Compare Direct and Transshipment Services

A direct service may reduce the risk of missed connections and terminal waiting, although it may cost more or operate less frequently.

Prepare Documents Early

Provide complete and consistent information before the carrier and customs deadlines.

Allow Contingency Time

Add additional time for:

• Peak seasons
• Congested ports
• Transshipment routes
• Customs inspections
• Weather-sensitive routes
• Holiday closures

Purchase Cargo Insurance

Carrier liability may not cover the full commercial value of delayed, lost or damaged goods.

Review the cargo insurance guide when planning the shipment.
