What Is ISPM-15?
The International Standard for Wood Packaging
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is a phytosanitary standard issued by the International Plant Protection Convention (IPPC) governing wood packaging material (WPM) used in international trade. Its purpose is to prevent the spread of invasive insects and plant diseases across borders via wood packaging.
Most countries participating in international trade — including the United States, EU member states, Canada, Mexico, China, Japan, Australia, and most others — require ISPM-15 compliant wood packaging for imported goods. Customs authorities can and will hold or reject non-compliant shipments.

The IPPC Stamp
Heat treated wood packaging receives the official IPPC mark stamped directly onto the wood. The mark includes: country code (US), producer/treatment provider number, and the HT (heat treatment) code. This stamp is the documentation customs inspectors look for at ports of entry.
