ISPM-15 is the international standard for heat treated and fumigated wood products developed by the International Plant Protection Convention (IPPC). The standard was created primarily to prevent the spread of disease and insects that can negatively affect native plants and eco-systems.
- Heat Treatment (HT): Wood packaging material should be heated in a schedule that achieves a minimum core temperature of 56 degrees Celsius for a minimum of 30 minutes.
- Methyl Bromide (MB) Fumigation: The wood packaging material should be fumigated with methyl bromide.
- Priority Worldwide operates an ISPM-15 certified facility. All products manufactured at Priority Worldwide facilities are certified for export worldwide.
The standard directly regulates solid wood material in excess of 6mm that are used to ship products internationally. ISPM 15 requirements apply to all species of coniferous (softwood) and non-coniferous (hardwood) packaging materials.
Dunnage must also be ISPM-15 compliant. The ISPM-15 standard has a specific mark for dunnage. If lumber is cut up for use as dunnage, that lumber should be marked every 60 cm (2 ft) so at least one such mark will be on all dunnage components.
The ISPM-15 standard requires that wood is debarked, treated by one of 2 optional methods as noted above and then stamped or branded with a mark of compliance approved by the IPPC.
