Methyl bromide pallets have been widely used in the past, but their environmental impact is a major concern. Methyl bromide is a potent greenhouse gas that contributes to ozone depletion.
The use of methyl bromide pallets has been phased out in many countries due to its harmful effects on the environment. The Montreal Protocol, an international treaty, aimed to reduce the production and consumption of methyl bromide.
Methyl bromide pallets can still be found in some parts of the world, particularly in areas with limited access to alternative pest control methods. These pallets pose a significant risk to the environment.
The good news is that there are safer alternatives to methyl bromide pallets available. For example, heat treatment and irradiation can be used to control pests without harming the environment.
Pallet Treatment and Safety
Pallets treated with methyl bromide are marked with the "MB" stamp.
Methyl bromide is a potent ozone-depleting substance that has been restricted in many countries due to environmental concerns.

Heat treatment is a non-chemical method that involves heating the wood to a minimum core temperature of 56°C for at least 30 minutes, making it a safer alternative.
To identify safe pallets, look for the ISPM 15 mark, which indicates heat treatment rather than chemical fumigation, or an 'HT' stamp signifying heat treatment.
Pallets with the EPAL mark are generally safer and less likely to contain toxic substances.
How to Identify Heat-Treated vs Treated Pallets
If a pallet has been used for overseas shipping, it will have a stamp from the International Plant Protection Convention (IPPC) that contains information about the country of origin and the treatment method used. This stamp is a great way to determine if a pallet has been heat-treated or methyl bromide treated.
The treatment codes on the stamp are as follows:
If you see an HT code, you can be sure the pallet has been heat-treated.
Identifying Safe Pallets
Identifying Safe Pallets is crucial for ensuring the safety of your home, family, and the environment. The International Plant Protection Convention (IPPC) requires all manufacturers of wooden pallets to properly treat their products to avoid the introduction and spread of quarantine pests.
To identify safe pallets, examine the pallet's stamps and labels for compliance with international safety standards, such as the ISPM 15 mark, which indicates heat treatment rather than chemical fumigation. This mark guarantees the wood has been treated to eliminate pests without using harmful chemicals like methyl bromide.
Look for an 'HT' stamp, signifying heat treatment, and avoid pallets marked with 'MB,' indicating methyl bromide fumigation. Additionally, check for other certifications like the EPAL (European Pallet Association) mark, which assures compliance with stringent manufacturing and safety standards.
Pallets with these certifications are generally safer and less likely to contain toxic substances. Inspect the pallet for any signs of stains, odors, or spills, which can suggest previous exposure to chemicals. Avoid pallets that have been painted or treated with unknown substances, as these could contain hazardous materials.

Here's a quick reference guide to help you identify safe pallets:
Remember, if a pallet doesn't have a stamp, it's likely a national pallet used for domestic shipping and may not have been chemically treated. However, without a stamp, you can't guarantee where it came from or what chemicals have been used on it.
Chemical Treatments and Risks
Methyl bromide pallets pose significant health risks due to the toxic fumes they emit.
Exposure to these fumes can cause headaches, dizziness, and respiratory distress.
Formaldehyde, a common chemical in wooden pallets, has been linked to an increased risk of developing nasopharyngeal cancer.
The International Agency for Research on Cancer (IARC) classifies formaldehyde as a Group 1 carcinogen, indicating sufficient evidence of its carcinogenicity in humans.
Methyl bromide has been associated with neurological symptoms such as cognitive impairment and motor dysfunction.
The U.S. Environmental Protection Agency (EPA) has listed methyl bromide as a neurotoxicant, highlighting the risk it poses to human health.
Acute and intense exposure to methyl bromide can cause a variety of neurological problems.
The pesticide enters the body via breathing air, skin, or eyes, and EPA lists it as a highly acute toxic substance.
Methyl Bromide Pallets
Methyl bromide pallets are a type of pallet that's been treated with a highly toxic gas to eliminate pests. This method is particularly effective at penetrating deeply into the wood, ensuring thorough pest control.
However, it's crucial to highlight that methyl bromide is a potent ozone-depleting substance, and many countries have restricted its use due to environmental concerns.
Pallets treated with methyl bromide are marked with the “MB” stamp, making it easy to identify them. This stamp is required by the International Plant Protection Convention (IPPC) to ensure compliance with international shipping standards.
Methyl bromide fumigation involves exposing the wood to a highly toxic gas for a certain period, which effectively eliminates pests. However, it's essential to keep your hands off of this material, as it's not safe for you and your family.
The use of methyl bromide is declining due to environmental and health concerns, making heat treatment a more popular alternative. Heat treatment involves heating the wood to a minimum core temperature of 56°C for at least 30 minutes, which eradicates pests by disrupting their biological functions.
In addition to the "MB" stamp, you can also look for other marks on the pallet that indicate treatment options for wood with no intent to decontaminate the material.
Environmental and Handling Considerations
The environmental impact of methyl bromide pallets is a major concern. Deforestation is accelerated by harvesting timber for pallets, which reduces forest cover and disrupts ecosystems, contributing to climate change.
Methyl bromide fumigation, a chemical treatment used to enhance pallet durability, is a potent ozone-depleting substance that harms plant and animal life and poses significant risks to human health.
Environmental Impact
The environmental impact of wooden pallets is a pressing concern that affects our planet in several ways. Harvesting timber for pallets accelerates deforestation, which reduces forest cover and disrupts ecosystems.
Deforestation contributes to climate change by reducing the ability of forests to sequester carbon. Forests are crucial for carbon sequestration and biodiversity.
Chemical treatments used to enhance pallet durability release harmful substances into the environment, including methyl bromide, a potent ozone-depleting substance. Methyl bromide can harm plant and animal life and pose significant risks to human health.
Disposal of wooden pallets contributes to waste accumulation and methane emissions in landfills. Recycling rates are low, and many pallets aren’t reused or repurposed effectively.
The decomposition process of chemically treated wood can release toxins, contaminating soil and groundwater.
Safe Loading and Unloading Practices
Loading and unloading pallets requires attention to safety protocols. Safety is a top priority in the logistics and shipping industry.
Proper handling of pallets is crucial to prevent accidents. Whether you're loading pallets on a trailer or unloading them from trucks, safety should always be the first consideration.
In situations where forklifts are used, ensure the operator is trained and experienced. This is especially important for lifting pallets.
Accidents can be prevented by following a step-by-step guide for every pallet situation. This includes considering the weight and size of the pallets.
Forklift loading pallets requires careful planning and execution. The pallets should be placed in a stable and secure position to prevent shifting or falling.
In the event of an accident, having a plan in place can help minimize damage and prevent further incidents.
Pine Pallet Treatment
Pine pallets are commonly treated to ensure they meet international shipping standards and are free from pests. Heat treatment and methyl bromide fumigation are the two methods used to treat pine pallets.
In Australia, pine pallets are treated to prevent pest infestations. Both heat treatment and methyl bromide fumigation can be used to treat pine pallets, but heat treatment is considered a more environmentally friendly option.
Heat treatment involves heating the wood to a minimum core temperature of 56°C for at least 30 minutes, which eradicates pests by disrupting their biological functions. This process is favored for its environmental benefits as it doesn’t introduce harmful chemicals into the pallet.
Methyl bromide fumigation, on the other hand, involves exposing the wood to a highly toxic gas that effectively eliminates pests. However, it's a potent ozone-depleting substance and many countries have restricted its use due to environmental concerns.
To identify whether pine pallets are treated, look for stamps or markings on the pallet. Heat-treated pallets will have an “HT” stamp, while methyl bromide-treated pallets will have an “MB” stamp.
Here are the three key ways to tell if pine pallet wood is treated in Australia:
- Stamps and markings: Look for stamps or markings on the pallet, such as “HT” for heat-treated or “MB” for methyl bromide-treated.
- Colour and odour: Heat-treated wood may have a slightly different colour or odour compared to untreated wood.
- Manufacturer information: Contact the pallet manufacturer or supplier for information about the treatment of the wood.
