Export Pallets in Los Angeles: ISPM-15 Compliance and What Your Business Needs to Know

Every year, billions of dollars worth of goods move through the ports of Los Angeles and Long Beach bound for markets across the globe. Behind nearly every one of those shipments sits a wood pallet — and if that pallet doesn’t meet international phytosanitary standards, the entire shipment can be stopped at the border. For businesses exporting from the greater LA area, understanding export pallet requirements isn’t optional. It’s a fundamental part of keeping cargo moving on schedule.

Whether you ship manufactured goods to Asia, agricultural equipment to Latin America, or consumer products to Europe, the pallets under your freight must comply with ISPM-15. Below, we cover the regulations that apply, how the Port of Los Angeles and Port of Long Beach enforce them, and practical steps to keep your supply chain compliant.

What Makes a Pallet an “Export Pallet”?

An export pallet is any wood pallet used to ship goods across international borders. Structurally, it may look identical to a domestic pallet. The difference is in the treatment. Under ISPM-15 — the International Standards for Phytosanitary Measures No. 15 — all solid wood packaging materials used in international trade must be treated to eliminate wood-boring insects and pathogens that could threaten ecosystems in the destination country.

The most widely used treatment method is heat treatment (abbreviated HT), in which the wood’s core temperature is raised to 56°C (132.8°F) and held there for at least 30 continuous minutes. Once treated, the pallet receives an official ISPM-15 stamp that customs inspectors look for at every port of entry worldwide. If you need a deeper dive into heat treatment itself, our ISPM-15 heat treated pallets guide covers the full process and certification details.

Why ISPM-15 Compliance Is Non-Negotiable

Over 180 countries enforce ISPM-15 as of 2026. That includes every major trading partner of the United States — Canada, Mexico, the European Union, China, Japan, South Korea, Australia, Brazil, India, and the United Kingdom, among many others. If you are shipping internationally from Los Angeles, the safest assumption is that your destination requires ISPM-15 compliant wood packaging.

The consequences of non-compliance are significant. A shipment arriving at a foreign port on untreated or improperly stamped pallets can be held for inspection, fumigated at the shipper’s expense, returned to the origin port, or destroyed. The financial impact goes beyond the direct costs — delayed deliveries damage customer relationships and can trigger penalties under time-sensitive contracts.

Port of Los Angeles and Port of Long Beach: What Exporters Should Know

The San Pedro Bay port complex — comprising the Port of Los Angeles and the Port of Long Beach — is the busiest container port system in the Western Hemisphere. Together, these two ports handle a large share of all U.S. containerized exports. Because of this volume, compliance enforcement is thorough and well-established.

Pre-Shipment Inspections

While ISPM-15 enforcement primarily happens at the destination port, that doesn’t mean you can ignore compliance on the outbound side. Freight forwarders and shipping lines operating out of LA and Long Beach routinely verify that wood packaging carries valid ISPM-15 stamps before loading containers. Catching a problem before the vessel departs is far less expensive than dealing with it after arrival overseas.

Container Loading Best Practices

It is not enough to use treated pallets if other wood components in the container are untreated. ISPM-15 applies to all solid wood packaging materials, including dunnage, blocking, bracing, crating, and skids. A single piece of untreated lumber inside a container can flag the entire shipment as non-compliant. Every wood component that touches or supports the cargo must carry the proper treatment and stamp.

Documentation and Traceability

Many experienced exporters keep records of their pallet purchases that tie each shipment to the treatment provider’s certification. While not legally required in all cases, this paper trail can expedite dispute resolution if a customs authority at the destination port questions the legitimacy of an ISPM-15 stamp. Ask your pallet supplier for treatment certificates or batch records when purchasing export pallets in volume.

Common Export Pallet Mistakes LA Businesses Make

Ordering Standard Domestic Pallets for International Loads

Companies that have shipped domestically for years sometimes transition to export markets without updating their pallet procurement. Standard pallets sold for domestic use are typically not heat treated. You must explicitly order ISPM-15 compliant pallets and verify the stamp on every unit before loading.

Reusing Pallets Without Verifying the Stamp

Recycled or refurbished pallets can be an economical option, but the ISPM-15 stamp must still be legible and intact. If the stamp has been worn away, painted over, or is otherwise unreadable, customs inspectors will treat the pallet as non-compliant. Always inspect reused pallets before adding them to an export shipment.

Ignoring Destination-Specific Rules

While ISPM-15 is a global standard, some countries impose additional requirements. Australia, for example, has particularly strict biosecurity rules and may require additional treatments or inspections beyond the ISPM-15 baseline. New Zealand, Chile, and several other nations have their own supplemental phytosanitary requirements. Research your destination country’s specific import rules before shipping.

Waiting Until the Last Minute to Source Pallets

Export-grade pallets are a specialty product. Not every pallet yard stocks them, and custom sizes may require lead time for treatment and stamping. Build pallet procurement into your export planning timeline rather than scrambling to source compliant pallets days before a container is scheduled for loading.

Choosing the Right Export Pallet Size and Type

The correct pallet size depends on your cargo dimensions, the container type, and the destination country’s preferences. The standard 48×40-inch GMA pallet is widely used in North American trade, but European markets often prefer the 1200×800mm EUR pallet, and Asian markets may call for different dimensions entirely.

Beyond dimensions, consider the material choice between wood and plastic. Plastic pallets are exempt from ISPM-15 because they cannot harbor pests, which simplifies compliance. However, wood remains the dominant material for export pallets due to its lower cost, wide availability, and proven strength. For most LA exporters, heat-treated wood pallets deliver the best combination of compliance and value.

Custom pallet sizes are also available for oversized or irregularly shaped cargo. If your products don’t fit standard dimensions, a supplier that builds custom export pallets to your specifications can help you maximize container space while maintaining full ISPM-15 compliance.

Industries in Los Angeles That Rely on Export Pallets

The diversity of LA’s export economy means that nearly every industry in the region uses export pallets at some point. Sectors with especially high demand include:

Aerospace and defense: Precision components shipped to international partners require pallets that meet strict handling and compliance standards.
Food and beverage: Packaged foods, beverages, and agricultural products moving to international markets must ship on treated pallets to satisfy both ISPM-15 and food safety regulations.
Textiles and apparel: The LA garment district exports finished goods worldwide, and every shipment needs compliant packaging.
Electronics and technology: High-value electronics demand pallets that provide both physical protection and regulatory compliance.
Automotive parts: OEM and aftermarket parts shipped to assembly plants and distributors abroad travel on export-grade pallets.

Regardless of your industry, the ISPM-15 requirement applies equally. There are no exemptions based on product type when solid wood packaging is used for international shipments.

How to Verify Your Pallets Are Export-Ready

Before loading any international shipment, run through this quick verification checklist:

✓ Every wood pallet in the shipment carries a visible, legible ISPM-15 stamp
✓ The stamp shows the HT (heat treatment) designation
✓ The stamp includes a valid treatment provider registration number
✓ All dunnage, blocking, and bracing lumber is also treated and stamped
✓ No untreated or non-stamped wood components are mixed into the container
✓ Pallet dimensions are appropriate for the container and destination market
✓ Treatment certificates or purchase records are on file for traceability

Taking five minutes to verify compliance before the container doors close can save weeks of delays and thousands of dollars in penalties on the other end.

Frequently Asked Questions

Do all wood pallets need ISPM-15 treatment for export?

Yes. Any solid wood pallet used in international shipping must be heat treated (or treated with an approved alternative method) and stamped in accordance with ISPM-15. This applies to new pallets, used pallets, and custom-built pallets. The only exception is packaging made from processed wood materials such as plywood, particle board, or oriented strand board, which are exempt because the manufacturing process eliminates pests.

Can I reuse ISPM-15 stamped pallets for multiple export shipments?

Yes, as long as the stamp is still legible and the pallet has not been repaired with untreated wood. If any component of the pallet has been replaced, the replacement lumber must also be heat treated and the pallet must carry a valid stamp. Inspect reused pallets carefully before each shipment.

How far in advance should I order export pallets?

For standard sizes, most suppliers can fulfill orders within a few business days. Custom sizes or very large orders may require additional lead time for heat treatment and stamping. As a general rule, place your order at least one to two weeks before your container loading date to avoid last-minute supply issues.

What is the cost difference between domestic and export pallets?

Export pallets carry a modest premium over standard domestic pallets due to the heat treatment process and certification. The exact difference depends on size, wood grade, and order volume.
