The pallet under an IBC is part of the unit — it carries the bottle, takes the forklift forces, and determines whether the tote can be safely stacked. Buyers tend to ignore the pallet type when shopping, but the choice between composite, steel, and wood drives a meaningful chunk of the total cost of ownership and most of the failure modes that take a tote out of service early.
Composite pallets
Molded HDPE or HDPE-and-wood-fiber composite pallets are the most common option on new and reused totes. They tolerate water, do not host insects, and last well in outdoor service. The downside is impact resistance — a sharp forklift hit on a cold day can crack a composite pallet in a way that wood would have absorbed. Expected service life in mixed indoor-outdoor use is about 6 to 8 years.
Steel pallets
Galvanized tubular steel pallets are the toughest option and the heaviest. They handle stacking and rough handling almost indefinitely, but they corrode at any galvanizing breach and they are the most expensive at the front end. For high-cycle reuse — say, a customer who refills and ships the same totes monthly — steel pays back over a five-year horizon. For one-trip use or stationary storage, the premium is wasted. Service life is 12-plus years if galvanizing stays intact.
Wood pallets
Wood pallets on IBCs are increasingly rare and for good reason — they absorb moisture, host pests, and break down in outdoor service. They are also the cheapest, which is why they still show up. For indoor industrial use in a dry climate they are fine for 3 to 5 years. For anything outdoor or food-grade, avoid them.
- Composite: best general-purpose, 6 to 8 year life, mid-cost
- Steel: longest life, highest cost, best for high-cycle reuse
- Wood: cheapest, shortest life, avoid for outdoor or food-grade use
- Mixed lots: ask the seller to sort by pallet type at order
A note on stacking ratings
Composite and steel pallets are typically rated for two-high stacking when full. Wood pallets on IBCs are usually rated single-tier only. If the buyer plans to stack — and most warehouse buyers do — the pallet type effectively dictates the storage layout. Worth asking about at quote time rather than discovering at delivery.
