If your pallets are headed overseas, you’ve probably heard about heat-treated (HT) pallets and the ISPM-15 regulations that go along with them. These rules aren’t just industry jargon, they’re essential for protecting global trade, agriculture, and ecosystems. Whether you’re new to export or simply looking to understand the difference, here’s what you should know.
What Are Heat-Treated Pallets?
Heat-treated pallets are standard wood pallets that have undergone a regulated heating process to eliminate pests, larvae, and potential contaminants inside the wood. Specifically, each pallet’s core is heated to 56°C (132.8°F) for at least 30 minutes, meeting the international ISPM-15 (International Standards for Phytosanitary Measures No. 15) requirement.
Once treated, these pallets receive a certified ISPM-15 stamp, a clear visual marker that customs officials look for during inspections. Without it, your shipment could be delayed, quarantined, or even denied entry into its destination country.
Why Heat Treatment Matters
The goal of heat treatment is simple: prevent the spread of pests and disease through wood packaging materials used in global shipping. But beyond compliance, heat-treated pallets also offer benefits that apply even to domestic operations.
Here’s why they matter:
- Regulatory Compliance: Required for most international shipments. Without the ISPM-15 stamp, pallets can be rejected at customs.
- Cleaner & Safer: The heat treatment reduces moisture and organic material, which helps prevent mold and contamination—ideal for sensitive industries like food, beverage, and pharmaceuticals.
- Durability & Longevity: The drying process makes wood less likely to warp or weaken, providing a longer service life for your pallets.
- Environmentally Conscious: Unlike chemical fumigation, heat treatment uses only heat—no chemicals—making it a more sustainable choice.
How to Identify a Heat-Treated Pallet
Look for the ISPM-15 certification mark, usually found on the side of the pallet stringer or block. This stamp includes the country code, the facility number that performed the treatment, and the letters “HT” to verify that it’s heat-treated.
If the pallet lacks this marking, it likely hasn’t been treated—and should not be used for export shipments.
