In Mexican logistics, estiba is how cargo (boxes, pallets or bundles) is stacked and secured inside a warehouse, a truck or a container, so the space is used well without the goods getting crushed, shifting or falling. Estibar is to stack it; desestibar is to unload it in order. The person who does it is an estibador.
It sounds like a warehouse detail, but it hits your brand directly: a crushed box at the bottom of a pallet is a product you can't sell, and a badly built pallet takes longer to receive.
One word, several meanings
If you search for "estiba" you'll find definitions that don't match. All three are right, depending on context:
- In Mexico, estiba means stacking: how boxes are piled on a pallet, in a rack or in a trailer.
- In ocean shipping, the oldest sense, it's stowage: placing cargo aboard a ship so it travels balanced.
- In Colombia and other countries, estiba is the wooden or plastic pallet itself. If a Colombian supplier asks for estibas, they want pallets. The sizes used in Mexico are in pallet sizes in Mexico.
The types of stacking you'll run into
| Type | Where it happens | What it protects |
|---|---|---|
| Pallet stacking | When your supplier builds the shipment | Boxes not crushing or shifting when the pallet is moved |
| Warehouse stacking | On the floor or in racks | Being able to pull what you need without taking everything else apart |
| Transport stacking | Inside the truck or container | Weight spread evenly, cargo not sliding in transit |
| Ship stowage | On the vessel | The ship's balance (the carrier handles this) |
The rules that prevent damaged goods
Most cases don't need formulas. These rules cover almost everything:
- Heavy on the bottom, light on top. Obvious, and still the most common mistake when a mixed pallet is built in a hurry.
- Box on box, corners aligned. A corrugated box carries weight through its walls and corners. When boxes are stacked in columns, the load runs down the corners; when they're interlocked like bricks, the pallet gets more stable but each box holds less. If layers are interlocked, make sure the bottom one is the strongest.
- Nothing hangs over the edge. A box that overhangs the pallet loses support right at one of its corners, and it's the first to get crushed or hit by the forklift.
- Respect the stacking limit. Many master cartons carry a printed symbol of stacked boxes, sometimes with a number: it shows the maximum number of identical boxes that can go on top. If your carton doesn't have one and your product is fragile, add it.
- Watch for moisture. Corrugated cardboard loses strength when it gets damp. A pallet that spent the night in a rainy yard won't hold the same.
- Secure the load. Stretch wrap, corner boards and strapping keep boxes from shifting. Inside a truck, gaps are filled or blocked so nothing moves when braking.
If you're choosing cartons, the difference between primary, secondary and tertiary packaging (and which one handles stacking) is in types of packaging.
Why stacking is also money
Stacking doesn't just decide whether your product arrives intact. It also decides what you pay:
- Space. Warehouses charge by pallet position or by cubic meter. A well-stacked pallet fits more product in the same position; a badly stacked one pays for air.
- Freight. The same goes for a truck or container: what doesn't fit well goes on a second trip. And with parcel carriers, a box bigger than it needs to be is billed by volumetric weight.
- Receiving time. A single-SKU pallet with labels facing out is received and put away much faster than a mixed pallet that has to be taken apart to count. We explain it in how inbound receiving works at a 3PL.
What to check before sending goods to a warehouse
Ask your supplier or your team for every shipment to arrive like this:
- One SKU per pallet whenever possible. If they're mixed, each SKU in its own layer or block.
- Labels facing out, with the SKU and units per carton.
- Height and weight agreed with the warehouse before shipping. Every operation has its own limits from racks, doors and forklifts: ask before building.
- Cartons that can take stacking: if your retail box is thin, it goes inside a sturdier master carton.
- Full stretch wrap and, for delicate products, corner boards.
FAQ
Are estiba and tarima the same thing? In Mexico, no: the tarima is the pallet, and the estiba is how the load is stacked on it. In Colombia and other countries, estiba is used to mean pallet.
What does desestibar mean? Unloading the cargo in order, without damaging it. In a warehouse, unloading well is part of receiving: the pallet comes down, it's separated by SKU, and it's counted.
How many boxes can be stacked? It depends on the carton's strength, the product's weight and the humidity. If the carton carries the stacking-limit symbol, that's the maximum. If not, ask your packaging supplier.
