What Shippers Need to Know About the International Standard for Phytosanitary Measures (ISPM 15)
ISPM 15 BACKGROUND
When shipping internationally, wood packaging materials like pallets, crates, and dunnage made from raw wood can carry harmful pests and diseases across borders. To mitigate these risks and protect global agriculture, the International Standard for Phytosanitary Measures (ISPM 15) was introduced in March 2002 under the International Plant Protection Convention, which is overseen by the United Nations Food and Agriculture Organization.
This standard has become a critical regulation for shippers, as many countries have adopted it to prevent the spread of quarantine pests and plant diseases through international trade.
KEY ISPM 15 REQUIREMENTS
To comply with ISPM 15 regulations, wood packaging materials must be treated to eliminate pests. There are two approved methods:
- Heat Treatment (HT): The wood is heated to a core temperature of at least 56°C (133°F) for a minimum of 30 minutes.
- Methyl Bromide Fumigation: The wood is treated with an approved dose of this fumigant.
After treatment, the wood packaging must bear the official ISPM 15 certification mark, a stamp indicating compliance. This mark ensures that the wood meets the phytosanitary requirements of importing countries.
In the U.S., compliance is overseen by the National Plant Protection Organization (NPPO), represented by the United States Department of Agriculture (USDA).
ISPM 15 EXEMPTIONS
Certain wood materials are exempt from ISPM 15 requirements, including:
- Wood that is 6mm or thinner in thickness.
- Processed wood products, such as plywood, particleboard, or oriented strand board (OSB).
These exemptions exist because these materials have a minimal risk of harboring pests.
COUNTRIES REQUIRING ISPM 15 COMPLIANCE
Currently, 84 countries enforce ISPM 15 regulations for wood packaging materials. However, many countries have additional requirements beyond ISPM 15, so it is crucial for shippers to verify the specific guidelines of the destination country before shipping.

WHY ISPM 15 MATTERS FOR SHIPPERS
Non-compliance with ISPM 15 can result in shipment delays, rejections, or costly fines. By Understanding the importance of complying with ISPM 15 regulations and ensuring proper treatment and marking of wood packaging, shippers can streamline their operations and avoid disruptions in international trade.
