Why Use Pallets for Container Shipments? (2026 Guide): Benefits, ISPM 15 & Best Practices

In international freight forwarding, palletization is the cornerstone of efficient material handling. Placing cargo onto standardized wooden, plastic, or metal bases allows forklifts and pallet jacks to load, unload, stack, and move goods rapidly across ocean container terminals, 3PL warehouses, and fulfillment centers.

Following global trade enforcement updates—including the full statutory and executive suspension of the US $800 Section 321 de minimis duty-free exemption, mandatory 10-digit HTS electronic entry declarations through the Automated Commercial Environment (ACE), and strict ISPM 15 wood packaging material (WPM) inspections—importers cannot afford transit damage or customs holds caused by poor packaging. Partnering with Super International Shipping guarantees compliant, pre-inspected palletization at origin hubs in China, ensuring rapid destination port clearance and lower total landed costs.

Selecting the appropriate pallet material and size depends on cargo weight, moisture sensitivity, destination market standards, and budget constraints:

Importers frequently choose between Palletized Containers (goods pre-stacked on pallets) and Floor-Loaded Containers (cartons stacked directly on the container floor). The table below outlines the real-world operational trade-offs for a 40ft High Cube (40HC) container:

The Bottom Line: While floor-loading maximizes cubic space for lightweight bulk goods, palletizing reduces destination labor costs by up to $700 per container and cuts unloading times from 5 hours to under 45 minutes, preventing costly truck detention fees.

When shipping goods internationally using solid wood pallets, strict pest-control laws apply. The International Standards for Phytosanitary Measures No. 15 (ISPM 15) mandates that all raw wood packaging material (WPM) thicker than 6 mm must be treated to eliminate invasive insects.

💡 Pro Tip: Plastic, presswood, plywood, and corrugated paper pallets are manufactured using high heat and adhesives, making them 100% exempt from ISPM 15 rules. If you want to bypass wood inspection delays entirely, opt for plastic or presswood pallets at origin.
