Shipping Pallets from Port of LA: What Exporters Need 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 is not properly treated and stamped, the entire shipment can be stopped at the border. For businesses exporting from the greater LA area, getting the pallet logistics right is a fundamental part of keeping cargo moving on schedule.

This guide focuses on the practical side of shipping palletized freight out of the San Pedro Bay port complex: how to prepare your shipment, which pallet sizes fit which containers, what industries export what, and the mistakes that cost LA businesses time and money at the dock.

The San Pedro Bay Port Complex: Scale and Significance

The Port of Los Angeles and the Port of Long Beach together form the busiest container port system in the Western Hemisphere. Located side by side in San Pedro Bay, these two ports handle a massive share of all U.S. containerized exports. For businesses across the Los Angeles metro area, the Inland Empire, Orange County, and the broader Southern California region, these ports are the primary gateway for ocean freight headed to Asia, Europe, Latin America, and beyond.

The sheer volume of cargo moving through the complex means that compliance systems are well-established, enforcement is routine, and there is very little room for error. Freight forwarders, shipping lines, and terminal operators all have processes in place to verify that wood packaging meets international standards before containers are loaded onto vessels.

How the Export Process Works at Port of LA and Long Beach

The Typical Export Timeline

Understanding the timeline helps you plan your pallet procurement around your shipping schedule. A typical export shipment from the San Pedro Bay complex follows this sequence: cargo is palletized and loaded into a container at your warehouse or a container freight station, the loaded container is transported by truck to the port terminal, the container clears terminal gate inspection and is staged in the yard, the container is loaded onto the vessel on the scheduled sailing date, and the vessel departs for the destination port.

The critical window for pallet compliance is before the container leaves your facility. Once the container doors are sealed and the cargo is in transit to the terminal, fixing a pallet problem becomes exponentially more expensive and time-consuming. Your pallets need to be verified as compliant before loading begins.

Pre-Shipment Compliance Checks

While ISPM-15 enforcement primarily happens at the destination port, the outbound side is not compliance-free. Freight forwarders operating out of LA and Long Beach routinely verify that wood packaging carries valid treatment stamps before issuing shipping instructions. Some shipping lines include pallet compliance in their booking confirmations. And if a problem is discovered at the terminal gate, your container can be turned away, forcing you to unload, fix the issue, and rebook — potentially missing your vessel.

Terminal Gate Procedures

When your truck arrives at a port terminal, the container goes through a gate process that includes document verification and sometimes physical inspection. While not every container is opened at the gate, random inspections do occur. If inspectors find non-compliant wood packaging, the container is rejected. The truck driver has to take it back to your facility, you fix the pallets, and you try again — all while the clock ticks toward your vessel's cutoff time.

Choosing the Right Pallet Size for Your Container

Container space is expensive. Choosing the wrong pallet size can waste cubic footage, increase your per-unit shipping cost, and create loading headaches at the dock. Here is how to match your pallets to your containers.

20-Foot Standard Container (TEU)

Internal dimensions are approximately 19’4” long by 7’8” wide by 7’10” tall. The standard 48×40-inch GMA pallet fits well in a 20-foot container, with room for approximately 10 pallets in a single layer when loaded two-wide. For lighter cargo where you can double-stack, this gives you 20 pallet positions. If you are shipping to Europe, the 1200×800mm EUR pallet offers slightly better space utilization in a 20-foot box.

40-Foot Standard Container (FEU)

Internal dimensions are approximately 39’5” long by 7’8” wide by 7’10” tall. You can fit approximately 20 standard GMA pallets in a single layer, or up to 40 positions if double-stacking is feasible with your cargo weight and type. The 40-foot container is the workhorse of ocean freight from LA, and most export pallet orders are sized for this container type.

40-Foot High-Cube Container

Same footprint as a standard 40-foot container but about 12 inches taller, giving you approximately 8’10” of internal height. The extra headroom is valuable for tall or bulky cargo. It does not change the pallet footprint or the number of pallet positions — it gives you more stacking height per position.

Destination Market Preferences

The 48×40-inch pallet dominates North American trade but is not the global standard. European buyers often prefer the 1200×800mm EUR pallet, which is narrower and fits European racking systems. Asian markets vary — Japan commonly uses the 1100×1100mm pallet, while other Asian countries may accept various sizes. Australian importers sometimes specify particular pallet dimensions to match their warehouse infrastructure. Confirm the preferred pallet size with your buyer before placing your order.

Industries in Los Angeles That Export on Pallets

The diversity of LA’s export economy means that nearly every industry in the region ships palletized freight through the port complex at some point. Understanding what your industry peers are shipping can help you anticipate pallet requirements and plan accordingly.

Aerospace and defense: Southern California is a major hub for aerospace manufacturing. Precision components, assemblies, and equipment shipped to international partners and foreign military customers require pallets that meet strict handling standards. Weight ratings and dimensional precision matter as much as compliance for these shipments.

Food and beverage: Packaged foods, beverages, nuts, dried fruits, and agricultural products are major LA-area exports. These shipments often require pallets that satisfy both phytosanitary requirements and food safety standards. Clean, new pallets are typically preferred over recycled ones for food-grade shipments.

Textiles and apparel: The LA garment district and surrounding manufacturing clusters export finished goods worldwide. Apparel shipments tend to be high-volume but relatively light, making them good candidates for double-stacking in containers.

Electronics and technology: High-value electronics demand pallets that provide physical protection during ocean transit. Anti-tip and anti-shift loading techniques are critical, and the pallets need to be sturdy enough to support bracing and strapping without splitting.

Automotive parts: OEM and aftermarket parts shipped from LA to assembly plants and distributors abroad travel on export-grade pallets. Heavy parts like engine blocks and transmissions require pallets with high weight ratings, while smaller components may ship on standard-duty pallets.

Furniture and home goods: The LA area exports significant volumes of furniture, fixtures, and decorative items. Irregularly shaped pieces often require custom-built pallets to provide stable support during transit.

Common Mistakes LA Exporters Make with Pallets

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 not heat treated. They look identical to compliant export pallets. The only visible difference is the ISPM-15 stamp — and if your pallets do not have one, your shipment will not clear customs at the destination. Always specify ISPM-15/HT pallets when ordering for export.

Forgetting About the Dunnage

Your pallets might be perfectly compliant, but if you add untreated blocking, bracing, or dunnage lumber inside the container, the entire shipment can be flagged as non-compliant. Every piece of solid wood in the container must be treated and stamped — not just the pallets. This includes corner posts, edge protectors made from solid wood, and any lumber used to fill gaps or prevent shifting during transit.

Missing the Vessel Cutoff

Pallet problems discovered at the last minute are one of the most common reasons LA exporters miss their vessel cutoff. If you discover that your pallets are non-compliant the day before loading, there may not be enough time to source replacements, reload the container, and get it to the terminal before the gate closes. Build pallet verification into your loading checklist at least several days before the scheduled container pickup.

Not Matching Pallet Size to Container Configuration

Using the wrong pallet size for your container can waste significant space. A few inches of dead space per pallet, multiplied across 20 pallet positions, adds up to cubic footage you are paying for but not using. Worse, improperly sized pallets can shift during transit, damaging cargo. Work with your pallet supplier and freight forwarder to confirm the optimal pallet dimensions for your specific container and cargo combination.

Reusing Pallets Without Inspection

Recycled pallets can save money, but they must be inspected before use in an export shipment. The ISPM-15 stamp must be legible and intact. Pallets repaired with untreated lumber lose their compliance status entirely. A quick visual check of each pallet before loading takes minutes and prevents expensive problems weeks later at the destination port.

Preparing Your Shipment: A Practical Checklist

Before your container is loaded, run through this checklist to prevent compliance and logistics problems at the port:

✓ Pallet size confirmed with buyer and matched to container type
✓ All pallets carry visible, legible ISPM-15 stamps with HT designation
✓ All dunnage, blocking, and bracing lumber is also treated and stamped
✓ No untreated solid wood components anywhere in the container
✓ Cargo is stable on the pallets and properly strapped or wrapped
✓ Container weight does not exceed the road weight limit for trucking to the port
✓ Shipping documents reference ISPM-15 compliance for wood packaging
✓ Treatment certificates or purchase records are on file for traceability
✓ Container loading date is scheduled with enough buffer before vessel cutoff

Taking fifteen minutes to verify everything before the container doors close can save weeks of delays and thousands of dollars in penalties at the destination. For details on what the ISPM-15 stamp components mean and how to read them, see our ISPM-15 regulation guide.

Alternatives to Wood Pallets for Export

If ISPM-15 compliance logistics are a persistent headache for your operation, consider alternatives that simplify the process.

Plastic pallets are completely exempt from ISPM-15 because they cannot harbor pests. No stamp, no treatment, no compliance risk. The tradeoff is higher per-unit cost, but for high-value cargo or destinations with especially strict enforcement (Australia, New Zealand), the compliance simplicity can justify the premium.

Slip sheets eliminate pallets entirely by placing cargo directly on thin plastic or fiberboard sheets. This maximizes container space and eliminates ISPM-15 concerns, but requires clamp-equipped forklifts at both origin and destination — which not all facilities have.

Engineered wood pallets made from plywood, OSB, or particleboard are exempt from ISPM-15 because the manufacturing process eliminates pests. They are lighter than solid wood pallets and do not require stamps or treatment certificates. Availability and load capacity vary compared to solid wood options.

For most LA exporters, heat-treated solid wood pallets remain the best combination of cost, availability, strength, and universal acceptance. But knowing the alternatives helps you make the right choice for your specific situation.

Frequently Asked Questions

How many pallets fit in a 40-foot container?

A standard 40-foot container can hold approximately 20 standard 48×40-inch GMA pallets in a single layer. If your cargo allows double-stacking, you can fit up to 40 pallet positions. The exact number depends on your pallet dimensions, cargo height, and weight limits.

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 a Port of LA shipment?

Place your order at least one to two weeks before your container loading date. Standard sizes are usually available within a few business days, but custom sizes or large-volume orders may require additional lead time for treatment and stamping. Factor in the time needed to inspect pallets before loading and transport the loaded container to the terminal before the vessel cutoff.

What if I discover my pallets are non-compliant the day before loading?

Contact your pallet supplier immediately to arrange rush delivery of compliant replacements. If time is too short for wood pallets, plastic pallets are an ISPM-15 exempt alternative that may be available on shorter notice. Missing a vessel cutoff due to pallet issues is costly — building pallet verification into your timeline several days before loading prevents this scenario.
