Export shipping introduces regulatory requirements that domestic freight does not face. One of the most common challenges for US exporters is complying with international rules governing wood packaging materials. In 2026, wood pallets remain widely used for export, but only when ISPM 15 requirements are clearly understood and properly managed.
This blog explains how ISPM 15 affects wood pallets, how US exporters stay compliant, and what logistics teams should build into their export processes.
What ISPM 15 requires
ISPM 15 is an international standard that regulates wood packaging material used in international trade. Wood pallets must be treated to prevent the spread of pests and diseases.
Key requirements include:
- Heat treatment to a specific core temperature
- Proper marking and certification
- Use of compliant lumber
- Ongoing verification and documentation
Failure to meet these standards can result in shipment delays or rejection at the destination port.
Why compliance matters in real operations
In US export logistics, a single noncompliant pallet can delay an entire container. Common failure points include:
- Missing or illegible treatment marks
- Mixed pallet inventories
- Last-minute pallet sourcing
- Lack of documentation
Export reliability depends on consistent pallet compliance across all facilities involved.
Heat treatment and supply planning
Heat treatment adds time and coordination to pallet sourcing. Exporters who rely on wood pallets must plan ahead to ensure compliant inventory is available when shipments are staged.
Facilities that integrate heat-treated pallet programs into their procurement strategy experience fewer disruptions during peak export periods.
Moisture and transit considerations
Export containers are exposed to humidity and temperature changes. Wood pallets can absorb moisture, which may affect structural integrity or raise concerns during inspection.
Proper pallet construction, treatment, and storage reduce these risks and help maintain compliance throughout transit.
Best practices for US exporters
To manage ISPM 15 compliance effectively:
- Separate export pallets from domestic inventory
- Train staff to recognize compliant markings
- Maintain clear documentation
- Audit pallet condition before loading
Consistency is the key to avoiding export issues.
Final takeaway
Wood pallets can be used successfully for export shipping when ISPM 15 requirements are built into procurement and handling processes. In 2026, compliance planning is essential for maintaining export reliability.
