There are numerous factors that determine the lifespan of a wooden pallet. Its frequency of use, how it has been handled, and what it has been used to ship all play a role, but the general consensus is that a wooden pallet can deliver around three to five years of use. Whether you're purchasing older wooden pallets that are in a reasonable condition, or newer wooden pallets no longer required by their original user, are they appropriate for re-use?

Pesticide Measures

Essentially, the condition of the pallet is the primary determining factor as to whether you can get use out of it, although even a pristine used wooden pallet might be of little use for your purposes. If you plan on utilising the pallet for any international export, remember that the pallet must have an ISPM 15 designation (International Standards for Phytosanitary Measures No. 15). This classification covers the pesticide measures taken to ensure that the wood in question is free from insects, as well as their larvae and eggs, greatly curtailing the inadvertent import or export of invasive insects.

Details of the Marking

It's essentially a biosecurity measure, and compliance with the measure can be determined by the presence of a stamp on the pallet itself, which also details the country where the wood was treated, the precise type of treatment (heat or chemicals), along with a certification number. The type of treatment is largely irrelevant for your usage, although chemical fumigation (usually abbreviated to MB, meaning methyl bromide) can restrict future use of the wood when the pallet has deteriorated to the point of no longer being useable. This means that these pallets can be unsuitable for firewood, or even for being repurposed in another form.

Unmarked Pallets

Just because a pallet does not carry the ISPM 15 marking does not mean it cannot be used, although this depends on your needs. Any untreated pallets in use in Australia can be used for domestic shipping since the pesticide treatment required for international export will not apply.

Sourcing Pallets

A reputable dealer will be able to provide you with the necessary pallets that are suitable for your purposes. Exercise caution when offered free pallets or when purchasing from an unknown source (such as a classified advertisement by a private individual). While the ISPM 15 marking can easily be identified, you should also look for corporate branding on the pallet. Many larger companies retain their own pallets in constant rotation, and it can be difficult to ascertain whether the pallet should have been sold to a new party when such branding is present.

Any pallet in an acceptable condition can conceivably be pressed back into service, but be mindful of the applicable requirements when that service requires international travel.
