The International Plant Protection Convention (IPPC) is a multilateral treaty deposited with the Food and Agriculture Organization of the United Nations (FAO) that aims to secure coordinated, effective action to prevent and control the introduction and spread of pests of plants and plant products across borders. Originally adopted in 1951, the convention was substantially revised in 1979 and again in 1997; the 1997 revised text entered into force in 2005 after the required two-thirds of contracting parties accepted it.
The IPPC operates through a Secretariat hosted by the FAO in Rome and is governed by the Commission on Phytosanitary Measures (CPM), which meets annually to adopt International Standards for Phytosanitary Measures (ISPMs). These standards — such as ISPM 15 on wood packaging material and ISPM 5 on phytosanitary terminology — are recognized under the World Trade Organization's Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) as the reference standards for plant health in international trade.
Each contracting party is required to establish a National Plant Protection Organization (NPPO) responsible for issuing phytosanitary certificates, conducting pest surveillance, and inspecting imports and exports. The IPPC also coordinates Regional Plant Protection Organizations (RPPOs), such as the European and Mediterranean Plant Protection Organization (EPPO) and the North American Plant Protection Organization (NAPPO).
Key functions of the convention include:
- Setting binding obligations for pest reporting and information exchange
- Developing science-based phytosanitary standards
- Providing dispute settlement procedures between parties
- Building capacity in developing-country NPPOs
The IPPC is frequently invoked in IR and trade contexts where invasive species, biosecurity, and non-tariff barriers intersect — for instance, in disputes over restrictions on agricultural imports justified on plant-health grounds. Note that the acronym IPPC is also sometimes used for the Intergovernmental Panel on Climate Change in older sources, though the IPCC is the correct abbreviation for that body.
Example
In 2002, the IPPC adopted ISPM 15, requiring wooden packaging in international trade to be heat-treated or fumigated, a standard now applied by major trading partners including the EU, US, and China.
Frequently asked questions
Yes. The convention itself is binding on contracting parties, though individual ISPMs are standards that become binding mainly through reference in the WTO SPS Agreement and national legislation.
