Plastic vs wood pallets: cost, weight, hygiene and fire code trade-offs

Wood costs less up front, can be repaired, and many U.S. handling systems are built around it. Plastic costs more, lasts in closed loops, washes clean and is outside ISPM 15, but an unlisted plastic pallet can push your warehouse into a tougher sprinkler category. The right choice depends on whether the pallet comes back, what you ship and how your building's fire protection was designed.

Side-by-side

Factor	Wood	Plastic
Purchase cost	Lower	Higher; common resins cost roughly 3–6 times as much as wood per pound
Weight	Varies by build and moisture	Varies widely by model; check the spec sheet
Repair	Standard repair methods restore strength	Generally not repairable
Hygiene	Nails, splinters, gives off moisture, can harbor insects	No fasteners, washable, weather resistant, insect-free
Fire code	The baseline that plastic is measured against	Unlisted pallets raise the commodity class by one or two classes
Export	ISPM 15 treatment and mark required	Not regulated under ISPM 15
End of life	Repaired, remanufactured, or ground for mulch, bedding and fuel	Recycled and reprocessed into new products

The cost and hygiene rows come from pallet engineer John Clarke's industry overview, reprinted by Pallet Enterprise. The fire and export rows are covered in detail below.

Cost

Plastic is the more expensive material. Clarke put the common pallet plastics (HDPE, polypropylene and PVC) at about 3 to 6 times the price of wood per pound, so a plastic pallet costs far more than a wood pallet of the same weight. We do not publish plastic prices. Get them from the manufacturer for the exact model.

Wood prices are easier to pin down. Recycled 48x40s run $4.75–$6.75 for Grade B and $6.75–$8.75 for Grade A, delivered by the full truckload, as published October 15, 2026. New wood pallets are quoted per order because they follow lumber prices.

The real test is cost per trip. A pallet that ships one way only needs to survive one trip, so a recycled wood pallet usually wins. Plastic earns its price back only when the same pallet makes many trips and actually comes back. Clarke noted that plastic pallets are most common in captive, closed-loop systems. Run your own numbers in the pallet cost calculator.

Weight

Both materials vary too much for a single number. New GMA-style hardwood pallets in a Virginia Tech study averaged 40.0 lb at 15% moisture content. Wood weight also depends on moisture, which Woodpack Global's standard does not limit unless your spec does. Plastic pallet weight depends on design and resin, so compare spec-sheet weights for the exact model you would buy.

Durability and repair

Clarke lists plastic's strengths as durability, cleanliness, no fasteners, no insects, weather resistance and design flexibility. He also lists its weak points: higher price, low friction (loads can slide), low stiffness, lack of repair options and fire ratings.

Wood's advantage is that it can be fixed. A Virginia Tech and USDA Forest Service study found that standard stringer repairs, metal plates and companion stringers, restore the bending strength of GMA-style pallets when properly applied. Recovery runs at a large scale: an estimated 326 million wood pallets were recovered and sold as recycled, repaired or remanufactured pallets in 2016.

If you plan to rack plastic pallets, use a model with a published rack rating and check it against your load and beam span.

Hygiene and product protection

Plastic has no nails or splinters, can be washed, does not harbor insects and stands up to weather. Clarke noted it is common in the dairy, pharmaceutical, beverage and automotive industries and at the U.S. Postal Service. Some makers, ORBIS among them, offer FDA-approved resin options.

Wood's drawbacks, per Clarke: fasteners that can damage product, splinters, moisture release, possible insects and a lot of variation from pallet to pallet. If you stay with wood in a food or pharma plant, write cleaning and condition requirements into your purchase order and inspect on receipt. See new vs recycled pallets for when to require new wood.

Fire code: check before you switch

NFPA 13, the Standard for the Installation of Sprinkler Systems, defines a plastic pallet as any pallet with any plastic in its construction. An NFPA fire protection engineer has written that plastic pallets are generally considered a higher fire hazard than wood.

How NFPA 13 adjusts for it, per the National Fire Sprinkler Association:

• Unreinforced polypropylene or HDPE pallets: the stored commodity's class goes up one class.
• Reinforced plastic pallets: up two classes, often into high-hazard territory.
• Other plastics: typically up two classes unless specific testing shows otherwise.

In the 2022 edition these rules sit in Sections 20.3.2.2.1 and 20.3.2.2.2. Ask the manufacturer which category a model falls in.

The exception is a pallet listed as equivalent to wood. NFPA 13 lets a plastic pallet be treated as wood when it is listed for that equivalency, and the International Fire Code lets pallets listed and labeled to FM 4996 or UL 2335 be treated as wood for sprinkler design. FM 4996 is FM Approvals' standard for classifying pallets as equivalent to wood pallets, and ORBIS marks its FM-approved models with "FM" in the model name.

The stakes are real. In one worked example in the International Code Council's Building Safety Journal, a Class II commodity moved onto unlisted reinforced plastic pallets went up two classes, and the sprinkler system would have needed about 55% more water than its original design.

Empty pallets count too. NFPA 13 has separate rules for idle pallet storage (Section 20.17 in the 2025 edition). Under one ordinary-hazard scheme, idle plastic pallet piles are limited to 4 feet high.

Before you switch, talk to your fire protection engineer, your insurer and your local fire official.

Export: ISPM 15

ISPM 15, the international standard for wood packaging, covers packaging made of raw wood and excludes wood processed to be free of pests, such as plywood. USDA APHIS lists plastic pallets among the packaging materials not subject to its wood packaging rules. Plastic pallets do not need ISPM 15 treatment or a stamp.

Wood pallets for export need ISPM 15 treatment and the IPPC mark. Woodpack Global's standard adds that repaired or remanufactured pallets must be retreated and remarked, with old marks obliterated. Heat treatment adds $1.00–$1.50 per pallet. See heat-treated pallets and ISPM 15.

Recycling and end of life

• Wood: recovered pallets are sorted, repaired or remanufactured and sold again. Wood that cannot be reused is ground, and USDA Forest Service research lists the uses: mulch, animal bedding, compost, soil amendments and fuel, plus particleboard and other board products.
• Plastic: damaged pallets can be recycled and reprocessed. ORBIS, for example, runs a take-back program that reprocesses end-of-life customer packaging, pallets included, into new product and can give credit toward future packaging. Ask about take-back before you buy.

Which one fits

Wood fits when:

• Pallets ship one way or leave your control.
• Delivered cost per load matters most.
• Your sprinkler design assumes wood pallets.
• You want to repair rather than replace.

Plastic fits when:

• Pallets run in a closed loop and reliably come back.
• You wash down equipment or need a nail-free, splinter-free platform.
• You export often and want to skip ISPM 15 treatment.
• The model is listed as equivalent to wood, or your fire protection is designed for plastic.

A third option is renting wood block pallets from a pool. Compare it in the pooling tool.

FAQ

Are plastic pallets cheaper than wood in the long run?

Only if they make many trips and come back. Plastic costs several times more per pound of material, so it pays off in closed loops, not in one-way shipping.

Do plastic pallets need ISPM 15 heat treatment?

No. ISPM 15 covers wood packaging made of raw wood, and USDA APHIS lists plastic pallets as not subject to its wood packaging rules.

Do plastic pallets change sprinkler requirements?

They can. NFPA 13 raises the commodity class one class for unreinforced polypropylene or HDPE pallets and two for reinforced ones. Pallets listed as equivalent to wood are treated as wood, and the International Fire Code accepts FM 4996 or UL 2335 listings for that.

Can plastic pallets be repaired?

Generally not, which is one of plastic's main trade-offs. Some manufacturers, such as ORBIS, take back damaged plastic packaging and reprocess it.

Are plastic pallets more sanitary than wood?

Plastic has no nails or splinters, washes clean and does not harbor insects, and it is common in dairy, pharmaceutical and beverage operations. If you use wood in a food plant, spec clean, dry pallets and inspect every load.
