U.S. Customs and Border Protection (CBP) and the Animal and Plant Health Inspection Service (APHIS) have issued guidance on ensuring compliance with Wood Packaging Material (WPM) standards. This guidance includes a comprehensive checklist designed to help exporters and shippers verify that WPM meets U.S. import requirements, reducing the risk of costly delays, inspections, or penalties.
Understanding WPM Compliance Requirements
Wood Packaging Material, such as pallets, crates, and dunnage, plays a vital role in shipping and logistics. However, untreated wood can introduce harmful pests and pathogens into the U.S., posing risks to agriculture and natural ecosystems. To mitigate these risks, the U.S. adheres to international standards established by the International Plant Protection Convention (IPPC).
The regulations mandate that WPM entering the U.S. must be treated and marked to certify compliance. Non-compliance can result in rejected shipments, additional inspections, or fines.
Key Points of Compliance
- Treatment Options:
- Heat Treatment (HT): The wood must reach a core temperature of 56°C for a minimum of 30 minutes.
- Fumigation with Methyl Bromide (MB): Wood must be fumigated for at least 16 hours, followed by aeration.
- Marking Requirements: Treated WPM must display a permanent and legible mark, visible on at least two opposite sides. The mark must include:
- The IPPC symbol.
- The ISO country code.
- A unique producer number.
- An abbreviation of the treatment type (HT or MB).
- Exemptions:
- Manufactured wood materials.
- Loose wood packing materials.
- Wood pieces less than 6mm thick.
Why This Matters
The reuse of WPM makes it challenging to verify treatment status, which is why adherence to these guidelines is critical. Non-compliance not only disrupts shipments but also increases the risk of introducing invasive species that can harm natural and agricultural ecosystems. The WPM checklist helps ensure shipments meet regulatory standards before departure, supporting smooth supply chain operations.
Next Steps for Exporters and Shippers
Shippers are encouraged to review the WPM checklist to verify compliance with U.S. import requirements.
