How to Build a Mixed Container: Five Models, One Container, Fewer Mistakes

A mixed container is the most useful tool a first-time importer has. Instead of spending a whole 40'HQ on one model that may not sell, you spread the risk over four or five designs, test them in the same market, then reorder the one that moves. It is also the part of the order most likely to go wrong, because a mixed load has to be correct on paper before a single carton is packed.

1. What "mixed" actually means

A mixed container carries several models, often from several workshops, consolidated under one booking, one set of documents and one departure date. It is not a part-load. With LCL your cartons share space with other shippers' cargo and get handled several times; in a mixed container the whole box is yours and every carton in it appears on your loading plan.

2. Start from cubic metres, not units

Buyers think in pieces. Containers are filled in CBM. A 20'GP holds roughly 28 CBM of usable space, a 40'HQ roughly 68 CBM. Before anyone can build a plan, every model must be quoted with its packing data:

• Carton dimensions in cm, and CBM per carton
• Pieces per carton
• Gross weight per carton
• Stacking limit, meaning how many cartons high before the bottom layer crushes

Packing method changes everything. The same kids scooter can ship 10 to a carton at 0.141 CBM or 2 to a carton in a display box — five times the freight for the identical product.

3. The loading plan is the actual deliverable

Ask for the loading plan before you transfer money. It should list model, colour, cartons, CBM, net and gross weight per line, then totals. A supplier who cannot produce that sheet has not shipped many mixed containers. The plan earns its keep twice: it proves the order fits before production ends, and at destination it is the checklist you unload against.

4. Five places mixed loads go wrong

• Weight before volume. A 40'HQ can be full at 55 CBM if the models are heavy. Look at payload, not just space.
• One model arrives short. A workshop delivers 40 cartons instead of 60. If the plan has no slack, the container ships short or sits waiting.
• Colour drift. Two similar reds made by two workshops read as two reds on a retail shelf.
• Documents. Each model needs its own description and HS line. A vague invoice costs days at customs.
• Loading order. Heavy models first, light cartons on top, and the model you want to sample near the door.

5. A sensible first mixed order

Four models at roughly equal value is a clean start: for example two 3-wheel scooters, one ride-on car and one tricycle. Keep 5% of the CBM free as slack, because cartons never pack as tightly in reality as they do in a spreadsheet. Then reorder double quantities of whichever two models sell, and drop the other two without having lost a container.

6. What to ask before booking

• How many CBM does each model take, and how many pieces per carton?
• Is the your MOQ counted per model, per colour or per container?
• Will all models ship on the same vessel, or will one lag?
• Who consolidates the cartons, and where?
• Can I see photos of the finished loading plan before the door closes?

Bottom line: a mixed container converts one risky bet into four small tests. The work is all in the plan, and the plan is free to ask for. Ask for it before you pay, not after the container is on the water.
