Plastic vs timber pallets for Australian export
Plastic export pallets sit outside ISPM-15 entirely — so your shipment skips heat treatment, the IPPC stamp and one of the most common causes of a biosecurity hold. For exporters, that single fact is the headline difference between plastic and timber, and it usually outweighs the higher purchase price the moment a pallet makes its second trip.
Plastic vs timber for export — the short answer
For most Australian exporters, plastic wins because it removes the timber treatment requirement and the inspection risk that comes with it, while running lighter and more consistently through the supply chain. Timber only stays ahead on a genuinely one-way, lowest-capital shipment where the pallet is abandoned at the destination and treatment is not a hurdle. Decide on three questions: does the pallet come back, does it go into racking, and does the freight get inspected for biosecurity.
Everything below unpacks those trade-offs — the actual ISPM-15 rule (and why plastic skips it), a worked 10-year cost comparison, footprint choice by market, and a short selection checklist. The aim is to let you brief a supplier in one sentence and get the right pallet back.
One framing helps before the detail: the cost of an export pallet is not the sticker price, it is the landed cost per trip. Timber loads its cost up front and at every border — a low purchase price, but a treatment fee, a heavier airfreight bill and an inspection risk on each movement. Plastic loads its cost into the purchase and then amortises it across many trips, with no treatment and a lighter deck. Whether plastic or timber is "cheaper" therefore depends almost entirely on how many trips you get and how many times the pallet is treated or inspected — which is exactly why the same question has a different answer for a one-way airfreight pallet and a closed-loop sea-freight pool.
What does ISPM-15 actually require?
ISPM-15 is the international standard for solid-wood packaging: pallets, crates, cases and dunnage made from raw timber must be heat-treated (or fumigated) and stamped with the IPPC mark before they cross most borders. The treatment kills the pests — borers, beetles and fungi — that hitchhike in untreated wood, and the stamp tells the receiving country it has been done. Australia's Department of Agriculture, Fisheries and Forestry sets out the wood-packaging rules that govern timber moving in and out of the country (agriculture.gov.au).
The practical burden is threefold. You pay for the treatment, you have to keep the mark legible and compliant, and you carry the risk that an inspector at the other end disagrees. A missing, smudged or non-conforming IPPC stamp can see a consignment held, re-treated, re-exported or destroyed at the importer's cost — and the delay is often worse than the fee. For perishable or time-critical freight, that uncertainty is the real expense.
"The conversation almost always starts about price, but it ends on biosecurity. Once an exporter has had a single consignment held at the wharf over a dodgy heat-treatment stamp, the per-pallet difference stops mattering — they just want the pallet to stop being a variable. Plastic does that, because there is nothing to treat and nothing to inspect on the pallet itself."

Why are plastic export pallets exempt from ISPM-15?
Plastic pallets are exempt because ISPM-15 only covers wood. The standard exists to manage a pest pathway that lives in raw timber; a moulded HDPE or PP pallet has no bark, no moisture pocket and no fibre for borers to colonise, so it is outside the scope by definition. There is no plastic equivalent of the IPPC stamp because none is needed — the material simply isn't a phytosanitary risk.
That is why a plastic pallet ships with no treatment record, no fumigation and no mark to police. For a high-frequency exporter, the compliance saving compounds: every timber load is a fresh treatment-and-inspection event, while a fleet of plastic pallets clears that hurdle once, structurally, by being the wrong material to worry about. It is the cleanest "set and forget" you get in export packaging.
The exemption also pairs with three operational wins that matter most precisely on export lanes. A moulded pallet is the same weight and the same footprint every time, which keeps automated wrapping, conveyor and ASRS lines fed without jams — timber's plank-to-plank variation is exactly what trips them. It is non-absorbent, so it does not soak up moisture in a humid container, swell, or carry the mould and pest load that gets flagged on arrival. And it has no loose nails or splinters to puncture shrink-wrap, contaminate food or pharma freight, or injure handlers. None of those are headline features, but across thousands of export movements they are where the durable saving actually accrues.
For a never-returning lane — sea or air freight where the pallet is abandoned or recycled at the destination — a light, nestable export pallet keeps the dead-weight and cube cost down while still skipping treatment:
Because it nests, a stack of empties takes a fraction of the footprint of block timber on the return leg or in storage — and at around 7 kg it shaves weight off every airfreight chargeable kilo. If your freight instead cycles between two sites, the economics flip toward a heavier, reusable deck (covered below), but for true one-way export this is the workhorse.
How do plastic and timber compare over 10 years?
Over a multi-year horizon, plastic's higher purchase price is offset by reuse, lighter freight and zero per-shipment treatment, while timber's low entry cost is eroded by replacement, treatment fees and inspection risk. The table below is an original, illustrative comparison built for a closed-loop or reusable export lane. It uses ratios and verified physical facts — not prices — so you can drop your own freight and pallet figures in. Plastic decks run roughly 40% lighter than equivalent timber, and plastic carries no ISPM-15 obligation; both of those are the load-bearing facts here.
| Factor (per reusable export lane) | Timber pallet | Plastic pallet |
|---|---|---|
| ISPM-15 treatment & IPPC stamp | Required every export movement | Not required — exempt |
| Biosecurity-hold risk (pallet) | Hold / re-treat / destroy if mark non-compliant | Pallet removed as a variable |
| Deck weight vs timber | Baseline (heavier) | ~40% lighter → lower freight / kilo |
| Typical service life | Few trips; splinters, soaks moisture, loses nails | Many trips; holds dimensions |
| Dimensional consistency | Varies plank to plank | Identical weight & footprint every unit |
| Hygiene / wash-down | Absorbs moisture; harbours pests | Non-absorbent; hot-wash clean |
| Upfront unit cost | Lowest | Higher (recovered through reuse) |
| Best fit | One-way, abandon-at-destination, no inspection | Reused, repeated export, hygiene-sensitive |
The break-even logic is simple: the more trips a pallet makes and the more often it is treated or inspected, the faster plastic's higher purchase price is repaid. A pallet that goes out once and never returns may never reach break-even — that is the one case where timber's low entry cost holds.

Which footprint should I export on?
Export on the footprint your destination market and its racking expect — getting this wrong wastes container cube and can force costly re-palletising on arrival. There is no single "export size"; the right answer is the one your customer's warehouse, racking and containers are built around. Three footprints cover most Australian export traffic:
- 1165 × 1165 mm — the Australian standard square footprint. Right when the load stays inside Australian supply chains or your customer specifically runs the AU pallet.
- 1200 × 1000 mm (ISO) — the most common international export footprint for sea freight to New Zealand, North America and parts of Europe.
- 1200 × 800 mm (Euro) — the standard for much of Europe and a frequent requirement for pharmaceutical and grocery lines into European DCs.
Two rules keep you out of trouble. First, match the load rating to the real job — size to the dynamic figure for transport, and to the racking figure if the pallet goes into beams at either end, never the flattering static number. Second, confirm the footprint with the customer in writing before you order, because a re-palletise at the destination erases any pallet saving you thought you'd made. Browse the full range and filter by footprint and load in the product finder.
When does timber still make sense?
Timber still makes sense on a genuinely one-way shipment where the pallet is never coming back, treatment is not a practical hurdle, and the absolute lowest upfront cost is the deciding factor. If a pallet leaves your dock once, gets tipped at the far end, and the consignee has no reverse logistics, the case for paying more for a durable plastic deck is weak — you'd be buying reuse you never use.
Even then, weigh the treatment and inspection risk honestly. If the destination is strict on wood packaging, or the freight is perishable and a hold would spoil it, the "cheap" timber pallet can become the expensive one the day it is detained. The decision is rarely about the pallet in isolation — it is about the whole lane: return logistics, inspection regime, hygiene requirements and how time-sensitive the goods are.
A useful middle path is to split your fleet by lane rather than standardising on one material. Many Australian exporters keep low-cost timber or light one-way plastic for the abandon-at-destination consignments, and run a pool of heavy-duty reusable plastic decks on the lanes that loop back, get racked, or move hygiene-sensitive product. That way each shipment carries the pallet that is cheapest for that movement, instead of paying a reuse premium on freight that never returns — or wearing treatment fees and hold risk on freight that does.
How do I choose the right export pallet?
Choose by answering four questions in order: does the pallet return, does it get racked, does it get inspected, and what footprint does the market require. Those four answers point straight at a spec, and they are exactly what a good supplier needs to recommend the right unit. Use this as your brief:
- Return or one-way? One-way → a light, nestable export pallet to minimise dead-weight and cube. Returns → a heavier, reusable deck whose cost is repaid over many trips.
- Racked or floor-stacked? Racked at either end → a rackable pallet sized to its racking rating, the lowest of the three load figures (load ratings explained). Floor or block-stacked → you can use the static figure.
- Inspected for biosecurity? Tight wood-packaging regimes are the strongest argument for plastic, because the pallet stops being a treatment-and-inspection event altogether.
- Hygiene-sensitive? Food, meat and pharma freight favour smooth, non-absorbent, hot-wash plastic over fibrous timber.
For a closed-loop export lane that also goes into racking at either end, a heavy-duty, rackable HDPE pallet is the long-run economical choice — built to come back many times, not be thrown away once:
It rates 10,000 kg static and a genuine 2,000 kg on the beam, runs the Australian 1165 footprint, and being moulded from recycled HDPE it washes down clean for food and pharma loads — the opposite end of the spectrum from the one-way air pallet above, and the right tool when the pallet is an asset you keep.

Common questions
Do plastic pallets need ISPM-15 treatment for export?
No. ISPM-15 applies only to solid-wood packaging material. Plastic pallets are not wood, so they fall outside the standard completely — no heat treatment, no fumigation and no IPPC stamp. That is the single biggest reason exporters move from timber to plastic, because it removes one of the most common causes of a biosecurity hold (agriculture.gov.au).
Are plastic pallets cheaper than timber for export?
Not per unit — a moulded plastic pallet costs more to buy than a one-use timber pallet. The saving comes over the pallet’s life: many more trips per pallet, no per-shipment treatment, lighter freight and fewer rejected or delayed loads. On a one-way shipment that never returns, timber can still be the lower-capital choice. On any reused or inspected lane, plastic usually wins on total cost.
What size export pallet do I need?
It depends on the destination. The Australian standard footprint is 1165 × 1165 mm; the most common international export sizes are 1200 × 1000 mm (ISO) and 1200 × 800 mm (Euro). Confirm your customer’s racking and container preference before you commit — the wrong footprint wastes container cube and can force re-palletising at the destination.
Can I rack a lightweight export pallet?
Usually not safely. Most light, nestable export pallets are built for one-way air or sea freight, not for beam racking, and carry no rated racking figure. If your pallets go into racking at either end, choose a heavy-duty rackable pallet and size to its racking rating, which is the lowest of the three load figures. See our load ratings guide for the static vs dynamic vs racking distinction.
Do plastic pallets get held up at customs like timber can?
Plastic removes the wood-packaging reason for a hold — it needs no treatment certificate or IPPC mark. Your goods still have to meet the destination’s import rules, but the pallet itself stops being a biosecurity variable. Timber, by contrast, can be held, treated, re-exported or destroyed if its mark is missing, illegible or non-compliant.
