Are Pallets Made Of Treated Wood?



Pallets, the unsung heroes of logistics and shipping, are essential for the movement of goods worldwide. As DIY enthusiasts and businesses alike discover the versatility of pallets, questions arise about the materials used in their construction. In this blog post, we'll delve into the world of pallets, exploring whether they are made of treated wood, the reasons behind treatment, and the implications for various applications.

  1. Common Materials for Pallets: Pallets can be crafted from various materials, with wood and plastic being the predominant choices. Wood, in particular, comes in different types, each with its own characteristics and applications.

  2. The Need for Treatment: a. Pest Control: Pallets, especially those used in international shipping, may undergo treatment to prevent the spread of pests across borders. This treatment is in accordance with international standards, such as ISPM 15, which aims to safeguard against the transportation of harmful insects. b. Durability: Wood treatment enhances the durability and lifespan of pallets, ensuring they withstand the rigors of transportation and storage. Treated wood is less susceptible to decay, fungi, and other environmental factors.

  3. Types of Wood Treatments: a. Methyl Bromide: Historically, methyl bromide was a widely used fumigant for pallets. However, due to environmental concerns and health risks, many countries have phased out its use. b. Heat Treatment: Heat treatment involves subjecting pallets to high temperatures, eliminating pests without the use of chemicals. Pallets treated in this manner are marked with "HT" (heat-treated) and are considered safe for various applications. c. Alternative Treatments: Some pallets may be treated with alternative methods, such as borates or copper-based compounds, which are considered safer for both the environment and human health.

  4. Identifying Treated Wood Pallets: a. Stamps and Marks: Pallets are often marked to indicate the treatment method. "HT" signifies heat treatment, while "MB" indicates the use of methyl bromide. These markings are crucial for identifying the type of treatment applied. b. Discoloration: Treated wood pallets may exhibit discoloration, stains, or a characteristic hue that can serve as an indicator of treatment. This is especially visible on the edges or corners of the pallet.

  5. Safety Considerations: a. Outdoor Use: Treated wood pallets are generally safe for outdoor use, but precautions should be taken to avoid prolonged skin contact. b. Food Contact: When using pallets for projects involving food, it is advisable to opt for heat-treated pallets or pallets with no visible signs of chemical treatment.

  6. Eco-Friendly Alternatives: a. Untreated Pallets: For those concerned about the environmental impact of treated wood, untreated pallets may be an alternative. However, they may have a shorter lifespan and may not comply with international shipping standards.

Conclusion: In the realm of pallets, the question of whether they are made of treated wood depends on various factors, including their intended use and international shipping requirements. Understanding the treatment methods, identifying markings, and considering safety implications empower individuals and businesses to make informed decisions when working with pallets. Whether opting for heat-treated pallets, exploring alternative treatments, or choosing untreated wood, the key lies in balancing functionality with environmental and safety considerations.
