A Guide to Ocean Freight, Customs Clearance & Holiday Shipping
Your cargo has officially left port. Now what? While your shipment is making its way across the ocean, there’s still plenty happening behind the scenes to ensure it reaches its final destination as efficiently as possible.
From monitoring vessel schedules and preparing customs documentation to coordinating port arrivals and inland transportation, international shipping involves much more than moving cargo from point A to point B.
And with the 2026 holiday season approaching, planning ahead is more important than ever.
At Radius International, our freight forwarding specialists and in-house customs brokerage team work together to help businesses navigate the shipping process, anticipate potential challenges, and find solutions that support their supply chains.
What Happens While Your Ocean Freight Shipment Is at Sea?
Once a container ship departs its origin port, several important steps still need to take place before cargo can be delivered.
1. Shipment Tracking and Vessel Monitoring
Ocean freight schedules aren’t always set in stone. Weather conditions, port congestion, vessel rotations, and transportation disruptions can all affect estimated arrival dates. Monitoring shipment progress allows importers and their logistics providers to prepare for changes and coordinate the next steps.
Radius International offers shipment visibility through its Radius 360° technology, helping customers stay informed with shipment updates and access to shipping documentation.
2. Customs Documentation and Clearance Preparation
One of the most important parts of importing goods into the United States happens before the vessel arrives.
Depending on the shipment, importers may need to prepare commercial invoices, packing lists, bills of lading, Importer Security Filings (ISF), and other documentation required by U.S. Customs and Border Protection (CBP).
For applicable ocean shipments, ISF information generally must be submitted at least 24 hours before cargo is loaded aboard the vessel at the foreign port. Waiting until a shipment is already on the water can therefore be too late for this requirement.
This is where working with an experienced customs brokerage team makes a difference.
Unlike freight forwarders that rely entirely on outside customs brokerage providers, Radius International has its own in-house customs brokerage team. Our freight forwarding and brokerage specialists can coordinate directly, helping customers prepare documentation, review import requirements, and navigate the customs entry process.

3. Port Arrival, Cargo Release, and Final Delivery
When a vessel reaches its destination port, cargo must complete the necessary customs and carrier release procedures before it can move onward. Depending on the shipment, this may involve customs examinations, terminal availability, container pickup appointments, and transportation arrangements.
Planning these steps in advance can help reduce the risk of delays and unexpected expenses, including demurrage and detention charges.
From ocean freight and customs brokerage to domestic trucking and warehousing coordination, Radius International helps customers manage the logistics beyond the port.
November 2026 Shipping Update: What Importers Should Know Before the Holidays
As November begins, the international freight market is transitioning from an extended peak shipping season into holiday fulfillment and year-end inventory planning. Although demand is beginning to moderate on some major trade lanes, that doesn’t necessarily mean shipping conditions are returning to normal.
Here are three developments importers should keep on their radar.
1. Ocean Freight Demand Is Easing, but Congestion Remains
While import demand is now moderating, congestion and vessel schedule disruptions continue to affect shipping reliability. Recent weather-related delays in Asia, changing vessel rotations, and congestion at European ports are among the factors influencing available capacity and transit schedules.
What this means for importers: Lower demand doesn’t automatically guarantee faster shipments. Businesses should continue monitoring vessel schedules, evaluating routing options, and allowing flexibility for delivery timelines.
2. Holiday Shipping Requires More Than Booking Vessel Space
While the extended import peak is easing, localized capacity constraints, weather disruptions, and elevated operating costs continue to affect transportation networks.
For importers, that means the focus shouldn’t stop at securing ocean freight capacity. Customs clearance, inland trucking, warehouse availability, and final delivery arrangements all need to be considered when planning inventory arrivals.
Businesses should also account for Thanksgiving on November 26, Christmas on December 25, and New Year’s Day on January 1, 2027, when holiday schedules may affect certain logistics operations.

3. Freight Capacity and Transit Reliability Still Vary by Route
DHL’s November 2026 Ocean Freight Market Update reports that global ocean freight demand has grown approximately 5% year to date, while more than 10% of global vessel capacity remains tied up in port congestion.
Changes to Suez Canal routings and shipping networks are also influencing schedule reliability.
For businesses comparing international shipping options, these conditions highlight why the lowest quoted freight rate isn’t always the most efficient choice. Transit times, routing reliability, potential storage charges, customs requirements, and final delivery costs should all factor into the decision.
Working with a knowledgeable freight forwarder can help businesses evaluate the bigger picture before committing to a shipping plan.
Why You Should Contact Your Freight Forwarder Before You’re Ready to Ship
One of the most common misconceptions about international shipping is that businesses need to have every detail finalized before contacting a freight forwarder.
In reality, some of the most valuable logistics conversations happen before a shipment is even booked.
You might still be comparing suppliers, determining shipment quantities, reviewing inventory needs, or deciding whether ocean freight or air freight makes the most sense.
That’s a great time to start the conversation.

- Explore shipping options: Compare ocean freight, air freight, and transportation solutions based on your budget, cargo, and timeline.
- Understand customs requirements: Identify documentation, classification, and import compliance considerations before cargo departs.
- Anticipate potential costs: Evaluate freight charges, duties, transportation expenses, and other factors affecting total landed cost.
- Plan for arrival: Consider customs clearance, warehousing, and inland delivery requirements in advance.
- Prepare for the unexpected: Build flexibility into your shipping plan when schedules, capacity, or business needs change.
