Adopted Plant Health Standards

Adopted IPPC Standards - International Standards for Phytosanitary Measures (ISPMs)

The Commission on Phytosanitary Measures adopts international standards for phytosanitary measures. The International Plant Protection Convention (IPPC) is the only international standard setting organization for plant health recognized by the World Trade Organization (WTO) under the Agreement on the Application of Sanitary and Phytosanitary Measures (the SPS Agreement).

Both contracting and non-contracting parties to the Convention are encouraged to implement these standards.

Standards in themselves are not regulatory instruments, but come into force once countries establish requirements based on specific standards within their national legislation. Requests for specific information on import requirements should be addressed to the national plant protection organizations of the country of import.

For more information about IPPC standards, contact Marina Zlotina, PPQ's IPPC Technical Director, at

Adopted NAPPO Standards -- Regional Standards for Phytosanitary Measures (RSPMs)

The North American Plant Protection Organization (NAPPO) develops science-based regional standards for phytosanitary measures (RSPMs) which are intended to protect regional agricultural, forest and other plant resources against regulated plant pests while facilitating trade. The NAPPO Executive Committee approves all RSPMs.
