What Is ISPM-15?
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is an international regulation that governs wood packaging materials used in international trade. It requires that all wood packaging — including pallets, crates, and dunnage — be treated to eliminate pests that could damage ecosystems in the destination country.
The Heat Treatment Process
Heat treatment (HT) involves heating the core of the wood to a minimum of 56°C (132.8°F) for at least 30 continuous minutes. This is done in specialized kilns under monitored conditions. Once treated, pallets are stamped with the IPPC (International Plant Protection Convention) mark, including the HT designation, country code, and producer number.
Why It Matters for Export
If you ship goods internationally using wood pallets, ISPM-15 compliance is not optional — it is a legal requirement in most countries. Non-compliant shipments can be rejected at customs, quarantined, destroyed, or returned at the shipper's expense. Ensuring your pallets carry the HT stamp avoids costly delays and penalties.
Methyl Bromide vs. Heat Treatment
Methyl bromide fumigation (MB) was once an alternative treatment method, but it has been largely phased out due to environmental concerns — it depletes the ozone layer. Heat treatment is now the globally preferred method: it is effective, environmentally safe, and leaves no chemical residue on the wood.
