Crushed Corners, Bent Rails: Stacking Evidence to Demand
Before you accept the next lot into storage, the packing design must carry its stacking evidence on the goods, not only in a file:...

ISPM 15 is the international standard that decides whether the wood in a furniture shipment is allowed across a border. It applies to raw wood packaging over 6 mm thick: pallets, crates, dunnage and bracing. That wood must be debarked, treated by an approved method, heat treatment or fumigation, and stamped with the IPPC mark showing the origin country, the treatment code and the producer registration. Plywood, OSB, plastic pallets and cardboard sit outside the standard, which is why most furniture protective packing already qualifies. In practice the failures happen in logistics rather than at the factory: a swapped pallet or unmarked dunnage added during consolidation can hold an entire container at destination. Write the packaging spec into the purchase order, photograph every stamp before the doors close, and file the photos with the bill of lading.
The standard governs raw wood packaging material over 6 mm thick. In a furniture load that means the pallets under the cartons, the crates around marble tops and glass, and the dunnage and bracing inside the container. The wood must be debarked, treated by an approved method, heat treatment or fumigation, and marked with the IPPC stamp that carries the origin country, the treatment code and the producer registration. Processed materials fall outside the scope: plywood, OSB, plastic pallets and cardboard. That exemption is why so much furniture ships on plywood bases, honeycomb corner protection and paper edge boards. The treaty framework and the national implementations are published by the International Plant Protection Convention, and enforcement on the dock comes down to one detail. A compliant pallet is identified by its stamp alone: no stamp, no certification, regardless of what the supplier’s paperwork says.

The stamp fails in logistics, not in production. A factory loads stamped pallets; a warehouse swaps a corner pallet; a container is consolidated at a third facility and raw dunnage enters with another supplier’s goods. Destination quarantine holds rarely stop at the offending pallet: inspections can hold the container, and re-export or destruction orders follow for the wood. Importers running consolidated programs, where a mixed container combines several factories’ goods as explained in our mixed container consolidation guide, should make ISPM 15 part of the consolidation checklist rather than a factory-level assumption, and verify the stamps at loading with photographs.
Three lines in the purchase order close most of the gap. Line 1 is the packaging spec: ISPM 15 stamped pallets and crates for the wood elements, plywood or honeycomb for protective packing, plastic or cardboard where the destination market prefers them. Line 2 is verification at loading: stamped pallets photographed against the packing list, so the record exists before the doors close. Line 3 is documentation: an export packing list that matches the pallet counts, filed with the commercial documents in our furniture compliance documents pack. Buyers using incoterms where the buyer contracts main carriage should still fix the packing standard in the purchase order, because packing happens on the seller’s dock regardless of who pays the freight.
Wood packaging is one layer in a document stack that also carries product compliance and origin. For furniture, that stack holds fire and safety test reports for the destination market, chemical compliance for finishes and composite woods, the HS classification that sets duty treatment, described in our furniture HS code 9403 guide, and the certificates of origin. A quarantine hold over packaging is the cheapest compliance failure to prevent and among the most expensive to experience, which is why our export checklist gives the pallet stamp the same weight as the fumigation and treatment certificates that some destination markets additionally require. Flat-pack and knock-down programs reduce wood volume further, using the packing logic shown in our sofa compression packaging guide. Every layer of the file, from entity verification to container loading, is anchored in the factory context described in the Foshan furniture manufacturer profile.
The walkthrough shows the packing and loading floor where pallet stamps and packaging lines are checked before dispatch.
Most wood packaging problems are visible before the doors close. These checks take minutes at the dock and prevent weeks of delay at the border.
Do plywood crates need the ISPM 15 stamp?
No. Processed materials such as plywood, OSB and cardboard are outside the standard’s scope because they carry no live wood pest risk. The stamp requirement applies to raw wood packaging over 6 mm.
Who is responsible if the container is held over wood packaging?
Responsibility follows the contract, which is why the packaging standard belongs in the purchase order with verification at loading, regardless of which incoterm allocates the freight cost.
Is heat treatment or fumigation better for furniture?
Heat treatment is the common choice because it leaves no chemical residue near upholstery and mattresses. Both are approved treatments, and the stamp is what customs reads.
Does plastic pallet use remove the issue entirely?
For the pallets, yes. Dunnage and bracing inside the container are the remaining raw wood risks, so the loading checklist still needs the stamp rule.
| Item | Specification |
|---|---|
| Scope thickness threshold | Raw wood packaging material over 6 mm thick: pallets, crates, dunnage and bracing. |
| Approved treatment methods | Debarked wood treated by approved methods: heat treatment or fumigation. |
| IPPC stamp contents | Stamp carries the origin country, treatment code and producer registration. |
| Exempt packaging materials | Plywood, OSB, plastic pallets and cardboard fall outside the standard's scope. |
| Preferred treatment for furniture | Heat treatment, because it leaves no chemical residue near upholstery and mattresses. |
