International moving to the U.S. is most commonly done by ocean freight. Once you've settled on sea shipping, most households get stuck choosing between groupage (LCL, shared container) and FCL (full container load).
Both options have their merits. Groupage bills flexibly by volume; FCL charges a fixed price per container. Each suits different shipping scenarios. But pick wrong and there's a price to pay: forcing an FCL when groupage would do can cost you tens of thousands of yuan extra, while choosing groupage when you need FCL could mean waiting a long time for consolidation and still not fitting everything in.
This article lays out clear criteria you can check directly across four dimensions, volume, transit time, item type, and customs clearance/delivery, to help families moving by sea choose the right option.
1. Core differences between groupage and FCL
Before choosing, you need to understand four basic differences between the two options.
Pricing
- Groupage: Billed by volume in cubic meters (CBM), using a tiered structure of a base price plus a per-CBM rate for additional volume. Groupage rates run around a few thousand yuan per CBM depending on city and route, and the cost per cubic meter gradually drops as volume grows.
- FCL: Charged a fixed rate per container type. A 20ft container holds roughly 25-26 CBM and a 40ft about 52-55 CBM. Whether you fill it or not, the price is the same.
Loading
- Groupage: Cargo from multiple customers bound for the same destination is consolidated into one container, splitting the ocean freight and port charges so even a small shipment gets a relatively low shared cost.
- FCL: One customer's goods occupy an entire container. You have the whole space to yourself, don't wait for other shipments to fill up, and the container ships directly to the designated terminal.
Transit time
- Groupage: The container is loaded only after enough cargo for the same destination has been collected, usually a wait of one to two weeks.
- FCL: Ships according to the sailing schedule after booking, so timing is more controllable.
Customs clearance
- Groupage: If the moving company operates its own consolidation service, it controls the whole transport chain and compliance risk is lower. But if several international moving companies share a container, a problem with one customer's cargo can bring inspection on the whole container.
- FCL: Customs clearance is independent and unaffected by other customers' cargo. However, if the container is selected for inspection, the entire container must be opened and examined.
2. How to decide between groupage and FCL
To decide, work through four factors: volume, transit time, item type, and delivery. These factors aren't fully separate, so if your volume falls right at a boundary, combine them with the other conditions before making a call.
Volume
Volume range reference
- Under 8 CBM: groupage clearly has the advantage; FCL is usually not worth considering.
- 8-18 CBM: groupage is likely more economical, unless you have special items or a hard time constraint.
- 18-26 CBM: a 20GP FCL is usually more cost-effective. Rates are close, and you save the waiting time.
- 26-50 CBM: groupage is the better choice. A 20GP is too small, and a 40GP wastes space.
- Above 50 CBM: a 40GP FCL is the clear winner.
One thing to note: some international moving companies don't offer FCL service in certain U.S. cities, so confirm destination coverage with your mover first.
Transit time
When volume falls in a borderline range, transit time is often the deciding factor.
The hidden time cost of groupage
Groupage must wait one to two weeks while shipments to the same destination are gathered. Popular cities (New York, Los Angeles, San Francisco, Seattle, Houston) fill faster; other cities take a bit longer. Add that to the 1-3 month ocean transit itself, and the full groupage process can end up half a month to a month longer than FCL.
When waiting is a bad idea
Consider FCL first in these situations, even if the price is slightly higher:
- Visa or entry dates are fixed (L1/H1B start dates, F1 semester start)
- A housing gap in the U.S. (goods arrive at port but you have no place to live, or your lease ends before the goods arrive)
- Furniture is required before you can settle in (an empty place sitting there waiting for these items)
If a delay truly disrupts things, temporary lodging or paying rent on an empty apartment can cost more than the difference in shipping rates.
When waiting is acceptable
- You're not in a hurry and still have your current home in China to fall back on.
- The furniture is a nice-to-have, not a necessity.
- Your schedule is relatively flexible.
That said, FCL also requires waiting for a booking and sailing schedule, and during peak season you may not get a vessel slot. The advantage of FCL is more controllable timing, not absolute speed.
Oversized and special-category items
Some items, such as oversized or special-category goods, must go FCL regardless of volume. That's a hard requirement.
Oversized and overweight items
- Any side over 3 meters: requires a sea-truck (ocean + truck) solution; standard ocean shipping can't handle it.
- Any side close to 4 meters or a single piece weighing over 150 kg: classified as oversized cargo, so you need to confirm an FCL or sea-truck plan separately.
Typical examples include extra-long sofas, oversized solid-wood furniture, and long one-piece desks.
High-value and fragile items
Items like pianos, marble, and artwork are safer in an FCL because the space is yours alone and they won't be stacked with other shipments and damaged.
Non-stackable fee
Valuable or oddly shaped items that can't have other cargo stacked on top incur a non-stackable fee. This cost shows up more clearly with groupage, because consolidated cargo relies on stacking to save space. In an FCL, it's all your own goods, so you have full say in how they're stacked.
Destination delivery
An FCL shipment is delivered as a full container after arrival at port, so the destination needs to be accessible to large trucks. If container delivery is limited at the doorstep (e.g., an apartment entrance or narrow road), extra transshipment or second-delivery fees may apply. These are common destination add-ons, so ask about them during the quoting stage before comparing. Groupage is unpacked after arrival and then delivered, which is more flexible. Narrow streets and apartment elevators are not a problem.
Five-step decision checklist: settle on a plan in 3 minutes
After reviewing the four dimensions, use this checklist to make a quick decision. Follow the five steps and you'll essentially have your transport method.
Step 1: Calculate volume
- Under 8 CBM → groupage
- 8-18 CBM → likely groupage; continue to Step 2 to confirm
- 18-26 CBM → a 20GP FCL may be more cost-effective; continue to Step 2
- 26-50 CBM → likely groupage; continue to Step 2
- Above 50 CBM → a 40GP FCL may be more cost-effective; continue to Step 2
Step 2: Check the destination
Does the destination city have FCL service? If not, use groupage. If yes, go to Step 3.
Step 3: Check your items
- Any item with a side over 3 meters or a single piece over 150 kg → FCL or sea-truck is required
- Pianos, marble, or other high-value fragile items → lean toward FCL
- None of the above → go to Step 4
Step 4: Decide on timing
Can you accept an extra 1-2 weeks for consolidation? If not, choose FCL. If yes, choose groupage. Within the borderline range, groupage gives better value.
Step 5: Check delivery access
Is the destination easy for large trucks to access? For apartments or narrow roads, FCL may incur transshipment or second-delivery fees, while groupage's unpacked delivery is more flexible. For a single-family home or anywhere a large truck can get in, either option works.
3. Frequently asked questions
Q1: For 15 CBM of goods, should I choose groupage or FCL?
This volume normally falls in groupage's sweet spot. In cities with FCL service, a 20ft container needs around 25 CBM to be worth filling; putting 15 CBM into one wastes space. If you're not in a hurry, groupage is the better fit. If you need it fast or have oversized items, then consider FCL, but accept that you'll pay the full container rate even when it isn't full.
Q2: Is FCL always more expensive than groupage?
Not necessarily. The cost mainly comes down to your shipment volume. For a small amount of furniture and luggage, groupage saves money. For a whole-house move with volume approaching or above 18 CBM, quote an FCL first. Beyond price, also weigh item type, timing needs, and customs risk.
Q3: How long does groupage consolidation usually take? Can it be expedited?
Usually one to two weeks. Popular cities fill faster; less popular destinations may take longer. Shipping lines won't dispatch a vessel just for a small amount of cargo, so pushing doesn't do much. If time is tight, take FCL.
Q4: What if my FCL isn't full?
If you're short by a few CBM, you can add a few extra boxes of clothes or books to fill it, or accept the cost of unused space in exchange for speed. But don't stuff unneeded items just to fill the container. You'd pay freight on things you didn't need anyway.
Q5: Does FCL clear customs faster? Is it inspected less?
Inspections are random, and choosing FCL won't reduce them just because of the transport mode. FCL's real advantage is clearance independence. It isn't affected by other customers' cargo. What actually affects inspection rates is declaration compliance, not whether goods travel as groupage or FCL.
4. Why choose Seapoe Relo
Groupage and FCL each have their place. The key is finding a moving company that can recommend a sensible plan based on your actual situation. Seapoe Relo has built extensive hands-on experience in U.S. ocean moves.
Groupage strengths
Seapoe runs its own consolidation service. Only Seapoe clients' cargo goes into the same container, with no outside shipments from strangers mixed in. Everything is stored and packed under a standardized process, with moisture-proof and shock-proof protection throughout. This lowers the risk of knocks and loss compared with public LCL services. With a large, stable customer base, Seapoe has regular high-volume sailings to the five major ports of New York, Los Angeles, San Francisco, Seattle, and Houston, so consolidation takes less time. Spreading booking, ocean freight, and customs costs across more shipments brings the per-unit price well below what you'd pay shipping on your own. The savings are obvious.
FCL strengths
Seapoe maintains long-term partnerships with multiple booking agents, so it can secure reliable vessel space with priority. Dedicated customer service monitors vessel movements in real time through a work platform. If anything unusual comes up, clients are notified right away and a response plan is prepared. For FCL customers, this means more stable sailings and greater transparency.
Warehouse and packaging strengths
Seapoe has dedicated self-operated warehouses in Beijing, Shanghai, and Guangzhou totaling over 10,000 square meters, plus a dedicated partner warehouse on the U.S. West Coast in Los Angeles. In China, clients get 30 days of free storage, making it easy to arrange shipment and delivery timing flexibly. Packing uses impact-resistant, moisture-proof materials that meet international moving standards. Professional packing crews follow standardized procedures, including packing at your home and secondary reinforcement of fragile and valuable items at the warehouse. This reduces the chance of damage in transit from the source.
Customs clearance strengths
Seapoe maintains a database of personal effects policies for different countries, updated in real time on duty-free allowances, tax rates, and prohibited or restricted shipping rules across major global markets. Years of high-volume operations have also built an experienced advisory team.
Conclusion
Groupage and FCL are the two mainstream transport options for a U.S. move by sea, and each fits different needs. Groupage bills flexibly by volume and suits small-to-mid-size shipments with a relatively open timeline. FCL charges a fixed price per container and suits larger volumes, tight timeframes, or special items. Neither is inherently better. It's about what fits your situation.
Choosing the transport mode is only part of it. Equally important is picking a mover that provides professional judgment based on your actual circumstances, runs the full logistics chain in-house, and handles customs compliance. Before you decide, send your volume list and item photos to a professional consultant, and get a customized plan based on what's available in your destination city.
