The implementation of the standard is the responsibility of the member countries and brings additional responsibilities to companies that import or export with some legislative changes.
It is the responsibility of the exporting country to notify and implement legislation authorising the international approval of the marking of heat treatment or methyl bromide fumigation.
It is the responsibility of the exporter to ensure that the wood used in the pallets exported bears the seal of the ISPM 15 standard.
It is the importer's responsibility to require that the wood packaging material used in imported pallets be stamped with the ISPM 15 standard.
It is the responsibility of the importing country to look for the ISPM 15 standard seal on pallets entering their country. But in terms of implementation, the entire burden is on the exporter.
