What Is ISPM-15 and Why Does It Matter?

ISPM-15 stands for International Standards for Phytosanitary Measures No. 15. It is a set of guidelines developed by the International Plant Protection Convention (IPPC), an agency of the United Nations Food and Agriculture Organization (FAO). The standard was created to prevent the international spread of insects, nematodes, and other organisms that live in raw wood.

Raw, untreated lumber can harbor invasive species like the Asian longhorned beetle, the pine wood nematode, and various bark beetles. When wood packaging materials travel across borders without treatment, these organisms can establish themselves in new environments and devastate local forests, agriculture, and ecosystems. ISPM-15 addresses this threat by requiring that all wood packaging materials — including pallets, crates, dunnage, and skids — be treated before international transport.

For Los Angeles businesses that export through the Port of Los Angeles, Port of Long Beach, or LAX cargo terminals, ISPM-15 compliance is not optional. Shipments containing non-compliant wood packaging can be rejected, quarantined, or destroyed at the destination country. That means lost product, delayed deliveries, and potentially significant financial losses.

The Heat Treatment Process: How It Works

Heat treatment (HT) is the most common method used to comply with ISPM-15. The process involves placing wood pallets inside a specialized kiln or heat chamber and raising the core temperature of the wood to at least 56°C (132.8°F) for a minimum of 30 continuous minutes.

This temperature and duration combination is scientifically proven to kill all life stages of insects and other organisms that inhabit raw wood — including eggs, larvae, pupae, and adults. The treatment must reach the core of the thickest piece of wood in the pallet, not just the surface, which is why the process requires calibrated equipment and monitoring.

Once the heat treatment cycle is complete, the pallets are inspected and stamped with the official ISPM-15 mark. This mark includes:

The IPPC logo: A wheat symbol indicating the pallet meets international phytosanitary standards
Country code: "US" for pallets treated in the United States
Producer/treatment facility code: A unique identifier assigned to the certified facility
Treatment code "HT": Confirming the pallet was heat treated (as opposed to methyl bromide fumigation, which is code "MB")

This stamp must be clearly visible on at least two opposite sides of the pallet. Customs officials at destination ports use these marks to verify compliance quickly and efficiently.

Which Countries Require ISPM-15 Compliance?

Nearly all countries that participate in international trade now enforce ISPM-15 requirements. As of 2026, more than 180 countries have adopted the standard. For Los Angeles exporters, this means virtually every international shipment containing wood packaging materials needs to be compliant. Key trading partners that strictly enforce ISPM-15 include:

European Union (all member states): Strict enforcement at all entry ports
China: One of the most rigorous inspectors of wood packaging materials
Canada: Requires ISPM-15 for all wood packaging from the US
Mexico: Enforces compliance at all border crossings
Australia & New Zealand: Among the strictest biosecurity enforcement worldwide
Japan & South Korea: Require compliant wood packaging for all imports
India: Enforces ISPM-15 with increasing rigor
Brazil & Argentina: Key Latin American markets with full enforcement

If your cargo is leaving the United States on wood pallets, crates, or any other wood packaging — it almost certainly needs to be ISPM-15 compliant. The only exceptions are shipments using processed wood products (like plywood, particleboard, or OSB) or non-wood packaging materials like plastic pallets.

Common Use Cases for Heat Treated Pallets in Los Angeles

Port of Los Angeles / Port of Long Beach Exporters: The two busiest container ports in the Western Hemisphere handle billions of dollars in cargo. Every wood pallet leaving these ports on an international vessel must carry the ISPM-15 stamp.
LAX Cargo Terminal Shippers: Air freight leaving Los Angeles International Airport on international routes has the same ISPM-15 requirements as ocean freight.
Automotive Parts Exporters: Southern California is a major hub for auto parts distribution. Companies shipping components to assembly plants in Mexico, Asia, or Europe need certified pallets.
Aerospace & Defense Contractors: High-value aerospace components require compliant packaging for international delivery to allied nations and commercial clients.
Food & Agriculture Exporters: California is the largest agricultural exporter in the United States. Produce, nuts, dairy, and processed foods shipped on wood pallets must meet phytosanitary standards.
Technology & Electronics: Silicon Beach companies and LA-area tech firms shipping hardware or equipment internationally need compliant pallets for every outbound load.

Frequently Asked Questions

What happens if I ship internationally on non-compliant pallets?

Your shipment can be rejected at the destination port, held in quarantine, or even destroyed — all at your expense. In some cases, the entire container may be returned to the origin country. Non-compliance can also result in fines from the destination country’s customs authority and damage to your relationship with the receiving party. It is always safer and cheaper to use compliant pallets from the start.

Is there a difference between heat treatment and kiln drying?

Yes. Kiln drying reduces the moisture content of wood for construction or furniture applications. Heat treatment under ISPM-15 specifically requires the wood core to reach 56°C for 30 minutes to kill pests. Kiln-dried wood may or may not meet this threshold. Only wood treated specifically to ISPM-15 standards and stamped by a certified facility is compliant for international shipping.

How long does the ISPM-15 stamp remain valid?

The ISPM-15 stamp does not expire as long as the pallet remains intact and has not been repaired with untreated wood. If any component of the pallet is replaced, the new wood must also be heat treated and the pallet re-stamped. We recommend inspecting pallets before reuse in international shipments to ensure the stamp is still legible and the pallet has not been modified.
