Sanitary Ware Export Packing: Why Toilets Break in the Last 400 Metres

The first container of toilets I ever handled lost 14 units out of 340 before it reached the customer. Not in the factory, not in customs. In the last 400 metres, when a pallet stacked three high on a soft ground surface tipped sideways off a pallet truck in a parking lot.

Sanitary ware packaging is one of those things nobody specifies and everybody has an opinion about after something breaks. Here is how I write the packing spec now, and what actually matters.

Carton grade has to match the weight, and vitreous china is heavy

A standard one-piece toilet with a tank weighs somewhere around 45-55 kg. A floor-standing pedestal basin with a full pedestal can be 40 kg. That is a lot of dead weight in a carton measuring roughly 750x450x800 mm, and it lands on corners and edges, not on faces.

The default cheap carton is a five-ply BC-flute box with a relatively light liner. For sanitary ware I want to see seven-ply (typically AB or BC+E) or a five-ply with a heavy liner, and I want the edge crush test value stated in the packing spec, not just ply count. Ply count is not a strength rating. A well-made five-ply with 200 g liners will outperform a sloppy seven-ply with recycled liners every time.

How to check quickly: cut a 100x100 mm square from the side wall of a carton and weigh it, then compare across suppliers. It sounds fussy, but it is the only way to compare cartons without a lab. A carton face that dimples under thumb pressure when it is empty is going to fail.

The foam is doing the work, not the box

The box holds the shape. The cushioning absorbs the energy. EPS moulded inserts are the standard and are fine if the fit is right. The failure I see most often is not the width but the base: a moulded foot piece that supports the rim but leaves the trapway or the base skirt unsupported, so all the load goes through one thin point. When the carton lands on a corner, the piece cracks from that point.

What I ask for in the packing drawing: moulded top and bottom inserts that make contact over the full footprint of the base, at least 25 mm of EPS at the most exposed points, and the toilet held so that the flush valve and tank lid cannot move independently. The tank lid is the single most commonly broken component, and it breaks because it is packed loose or sits directly against the carton.

EPE foam is a step up and worth it for higher-value product. It recovers better after impact, does not crumble into the bowl, and can be shaped to fit. It costs more per unit but the damage rate usually drops below 0.5%.

Stacking and palletisation are where the damage actually happens

Factory packaging protects the unit inside the box. Palletisation protects the boxes from each other. A pallet of 8-10 cartons stacked three high and wrapped in stretch film looks tidy, but the bottom carton is taking the weight of two above it, and if the pallet is set down on gravel or a ramp, it goes.

For export, I specify: max two high, cartons square and corner-aligned, an angle-board or edge protector on all four vertical corners, a pallet that is the size of the carton footprint or larger, no overhang, and a double wrap of stretch film plus two PET strapping bands. For a mixed container, the heavy pallets go at the bottom and near the doors are the light boxes, and there is a documented loading plan. That plan is the thing you ask for and the thing that gets ignored, so make it a contract annex.

If the shipment is going LCL, be stricter. LCL containers are consolidated and re-handled more than anyone admits. I treat LCL sanitary ware as FCL-spec packing plus a plywood crate for anything over 30 kg.

Tray and fitting shipments need their own rules

Shower trays are big, flat and fragile. They must be shipped on edge, never flat, and if they are stacked, they need a separator that is rigid, not just foam. I have seen 60 trays crack in the middle because they were stacked twelve high with EPS sheets between them and the pallet sagged.

Small fittings (hoses, brackets, seat hinges, flush valves) cause a different problem: they disappear. Bag counts per carton, a packing list inside every carton, and a sealed inner bag all sound obvious until you are short 200 washers on a 40HQ. Weigh a carton and record it. Weight discrepancies are the cheapest way to find a short pack.

The testing that tells you whether any of this works

ISTA 3A or ISTA 2A drop and vibration testing on a fully packed pallet or carton is the objective way to settle the argument. It is not expensive relative to the value of the goods, and factories that can show a current report usually care about packing. Ask specifically whether the test was run on the product at the current weight and with the current carton.

Failing that, a practical alternative: ask for one pallet to be dropped 600 mm onto concrete on a corner at the factory. Open it. Look. It is crude, but it is real, and it is a fifteen-minute test.

The cost of getting this wrong

At a landed cost of perhaps 60-90 USD per toilet into a Western market, and a customer-facing replacement cost of 250-400 USD once you include the installer's second visit, a 1% damage rate is more expensive than a 3-4 USD packaging upgrade. Most of the buyers I have dealt with discover this in the opposite order. Specify the packing before you agree the price, put it in the purchase order as an annex with a drawing, and make the carton weight and ply grade something you can verify on the loading dock with a knife and a pocket scale.
