Corrugated vs wooden pallets: the ISPM-15 question

What is ISPM 15 — and why does it exist?

ISPM 15 — International Standard for Phytosanitary Measures No. 15 — is the global rule for wood packaging material, developed under the International Plant Protection Convention (IPPC). Raw wood can carry live forest pests — bark beetles, wood-boring larvae, nematodes — that devastate forests when they land on a new continent inside a pallet. The standard therefore requires solid-wood packaging used in international trade to be debarked and then heat-treated or fumigated, and marked with the IPPC stamp identifying the country, the treatment facility and the method. Plant-quarantine officers at the destination port check that mark; non-compliant wood can be treated, destroyed or re-exported at the shipper's expense.

Where do wooden pallets slow exporters down?

For an exporter, ISPM 15 adds a process to manage and a risk to carry. Treated pallets must be sourced from certified treatment facilities, the stamp must be present and legible on each pallet, and the paperwork has to satisfy inspection at destination. Each is a small task; together they create failure points. A worn or missing stamp, a pallet swapped during consolidation, or a quarantine officer who questions a mark can hold an entire container — and demurrage, re-fumigation or re-export costs land on the shipper. For high-volume RMG shipments moving on tight retail windows, one held container can mean a missed distribution-centre booking and a chargeback conversation nobody enjoys.

Why are corrugated pallets exempt from ISPM 15?

The standard targets raw, solid wood because that is where pests live. Processed wood-based materials — plywood, particle board and paper products such as corrugated board — fall outside its scope, because the heat, pressure and processing involved in manufacturing them eliminates the pest risk by default. A corrugated pallet therefore needs no treatment, no stamp and no fumigation certificate, and it raises no plant-quarantine question at any border. It is simply packaging, like the cartons stacked on top of it. Our cardboard pallets are corrugated, glued and load-checked in-house, in standard and custom footprints, and ship from the same plant as your master cartons.

What else do you gain by switching?

Weight, handling and recycling. A corrugated pallet typically weighs a fraction of its wooden equivalent — which matters most on air freight, where chargeable weight is money, and still helps on every road leg. There are no nails or splinters to injure handlers or snag garments. And at the destination warehouse, the entire unit load — cartons and pallet together — goes into a single recovered-fibre stream instead of leaving the buyer to manage wood disposal separately; that one-material story also supports the commitments described on our sustainability page. For the unit-load arithmetic — carton footprint, pallet tiling and stack height — our guide to choosing the right export carton covers the method.

When is a wooden pallet still the right call?

Honest answer: sometimes. Closed loops where pallets cycle between fixed points for years, very heavy point loads, and long-term outdoor or high-humidity storage still favour timber. But for one-way export consignments of garments and consumer goods — light, boxed and containerised — the corrugated pallet carries the load comfortably while removing the ISPM-15 process entirely. If you ship one-way and you are still scheduling fumigation, send your load details through our request for quotation and we will spec a fumigation-free pallet alongside your next carton order.
