What it does for pallets
The NPPO decides who may apply the IPPC mark in its country, supervises them, and assigns the producer or treatment-provider code that follows the country code in the mark. When a border inspector questions a mark, the NPPO of the marking country is who they ask.
Who it is in the US and Canada
In the United States the NPPO role sits with USDA APHIS; in Canada, with the Canadian Food Inspection Agency. Each country's IPPC contact page names its official organisation.
Using our country pages
Our country pages list the NPPO name as given on the IPPC country page, the date that contact was registered, and a link to the IPPC page so you can check current details yourself. Formats for producer codes vary by country; the NPPO is the authority on what a valid code looks like.
