Plant Pests

Heat treatment or fumigation of solid wood packaging helps prevent the transport of plant pests from one country to another.

Heat Treatment

The heating process must achieve a minimum wood core temperature of 56° Celsius (greater than 130°F) for a minimum of 30 minutes.


Fumigation of pallets and crates using methyl bromide is also an acceptable practice, but not as widely used as heat treatment.


Treated pallets must display the IPPC mark. Some countries require extra paperwork or bark treatment in addition to treating.

Delays for Exempt Materials

Plywood and OSB are exempt and do not require IPPC stamps. Sounds great until an import inspector doesn't recognize the material as exempt. Our experts help you avoid the pitfalls of exporting all wood materials.

ISPM-15 Current Requirements

Something as small as not having IPPC stencils on both sides of your wood pallet or crate can hold up your export shipment. Wood dunnage has special requirements.

ISPM-15 is the international standard requiring pallet heat treatment or fumigation.

Treated pallets are marked in a visible location with a legible and permanent mark approved by the International Plant Protection Convention (IPPC). This mark certifies that the wood pallets meet approved treatment standards.

Exporters are always at the mercy of inspectors at the receiving country, even with proper treatment or exempt materials.

To avoid solid wood packaging export issues, familiarize yourself with requirements and always work with a reputable pallet supplier.
