What Actually Happens to International Shipping During the Holidays?
December creates a lot of confusion for people planning an international move.
Some assume everything shuts down. Others assume shipping runs normally but costs more. Many don’t know whether starting anything in December is pointless because of the holidays.
The truth sits in between.
International shipping does continue during the holidays, but it does not operate the same way it does the rest of the year. Understanding what actually slows down, what keeps moving, and what quietly backs up can help you plan realistically instead of guessing.
International Shipping Does Not Fully Shut Down
One of the most common misconceptions is that international shipping stops entirely in December. That’s simply not the case.
Ocean vessels continue sailing on established routes, ports remain operational, and freight continues to move across borders every day, even during the holiday period. Global trade doesn’t pause simply because the calendar reaches the end of the year. Supply chains are designed to function year-round, and international shipping is a continuous system.
What does change is how efficiently that system operates and where delays are most likely to occur. Staffing levels are often reduced, administrative offices may run on limited schedules, and coordination between different parties can take longer than usual. Tasks that normally move quickly, such as document reviews, scheduling confirmations, or inspection assignments, may slow slightly, even though the physical movement of cargo continues.
Understanding this distinction is important. December shipping isn’t about stoppages, it’s about reduced margin for error. When timelines are realistic and preparation is handled early, shipments move through December without issue. When planning assumes business-as-usual speed and flexibility, small slowdowns can feel like major disruptions.
The Real Slowdowns Happen Around People, Not Ships
Ships don’t take holidays, but people do.
December affects staffing across almost every part of the international moving process. Packing crews take scheduled time off. Customs offices operate with reduced staff. Destination agents manage holiday schedules. Even document-processing offices may close for extended periods depending on the country.
Individually, these slowdowns are manageable. Collectively, they reduce flexibility. Tasks that might normally take a few days can stretch longer simply because fewer people are available to handle them.
This is why December planning focuses on expectation-setting, not speed.
Customs Processing Often Takes Longer Than Expected
Customs is one of the areas most affected by the holidays.
While customs offices generally remain open, many operate with skeleton staffing between mid-December and early January. Files may be accepted but reviewed more slowly. Inspections may be scheduled further out. Questions may take longer to resolve.
This doesn’t mean shipments can’t clear customs in December. It means customs becomes less forgiving of errors. When documents are prepared early and accurately, December customs clearance is usually uneventful. When paperwork is rushed or incomplete, delays are more likely to carry into January.
This is why customs preparation before the holiday period is especially valuable.

Packing and Pickup Scheduling Is Where December Feels Tightest
From a household’s perspective, the most noticeable holiday impact is often packing availability.
Many professional packing teams book up early in December due to holiday schedules and year-end demand. Preferred dates can disappear quickly, especially in major metro areas.
When packing is scheduled early, December works just fine. When packing is left until the last minute, options narrow, and schedules become less flexible.
This is another reason December planning conversations often focus on reserving future capacity, even if packing won’t happen until January.

Shipping Schedules Continue, But Cutoffs Matter More
Ocean carriers do maintain sailing schedules throughout December, but the importance of cutoffs increases significantly during this period. Documentation deadlines, container gate cutoffs, and consolidation windows are often adjusted around holidays, sometimes by just a day or two, but those small shifts can have outsized effects on shipment timing.
In late December, missing a cutoff doesn’t usually mean waiting a few extra days. It can push a shipment into the next available sailing cycle, which may fall in early or even mid-January, depending on the route and consolidation schedule. This is especially true for shared container and groupage shipments, where timing depends on multiple shipments aligning within a narrow window.
When timelines are planned conservatively, these cutoff sensitivities rarely cause major issues. There is enough buffer built into the plan to absorb a missed window without disrupting the overall move. Problems tend to arise when shipments are rushed to meet year-end dates without margin. In those cases, a single missed cutoff can undo weeks of planning and create frustration that could have been avoided with a more realistic schedule.
Destination-Side Delivery Often Slows Quietly
Even when shipments arrive on time, destination-side delivery can slow in late December and early January.
Housing may not be ready. Delivery crews may be limited. Local holidays vary by country and can affect unloading schedules. These delays are usually short, but they matter if expectations aren’t set correctly.
This is where planned storage can quietly protect a move from stress, especially when arrival dates and delivery readiness don’t align perfectly.

Why December Planning Still Works So Well
Despite these slowdowns, December remains a strong time to plan an international move.
Planning is largely unaffected by holiday closures. Conversations, assessments, customs reviews, and shipment strategy can all move forward without pressure. In many cases, December planning allows issues to be identified and resolved before January demand spikes.
The people who struggle most with December shipping are usually those who expected December to function like March. The people who do best are those who understand December’s rhythm and plan around it.
What December Is Best Used For
December is ideal for the parts of an international move that benefit most from time and reflection. It’s an excellent moment to clarify timelines and identify constraints before pressure sets in. Even rough timing, such as a likely departure window or expected arrival period, allows movers to map out realistic options and flag potential conflicts early. December is also well suited for reviewing customs requirements. Understanding documentation needs, eligibility windows, and potential restrictions ahead of time prevents rushed paperwork later, when delays are harder to fix.
This month is also a smart time to decide what should ship first and what can reasonably wait. Shipment sequencing affects cost, customs treatment, and how smoothly life begins at destination. Making these decisions early, without urgency, often leads to more thoughtful and flexible shipping plans. In addition, December allows movers to tentatively reserve packing and shipping capacity for January or February, protecting preferred dates and options without requiring immediate execution.
Where December is less helpful is in situations that rely on speed and flexibility. Rushing shipments to beat the end of the year often creates more problems than it solves, especially when cutoffs and staffing limitations come into play. Assuming instant availability can lead to disappointment, as packing crews, shipping slots, and documentation processing are often more limited during the holidays. Expecting last-minute flexibility is also risky, since December systems are designed to operate steadily, not absorb urgency.
Understanding this distinction changes the entire experience. When December is used for preparation rather than acceleration, it becomes one of the most effective months to set an international move up for success.
How SDC Manages Holiday-Season Moves
For December moves, SDC focuses on coordination and realism.
That means confirming cutoff dates early, aligning documentation well ahead of shipping, and setting delivery expectations that reflect holiday conditions. Where needed, storage and phased shipping are used strategically rather than reactively.
The goal is not to push moves through December faster than the system allows, but to guide them through December smoothly.

The Takeaway
International shipping doesn’t stop during the holidays, but it does slow in predictable ways.
December works best when it’s used for planning, alignment, and protection, not urgency. When expectations are realistic and preparation starts early, holiday-season shipping is rarely a problem.
The real risk isn’t December itself, it’s misunderstanding how December actually works.
