The  fumigation program is designed to have a system in place that will allow WPM to be used in export thus, facilitating international trade without the associated problem of quarantine forest pests. Here is the list of countries that are now  implementing ISPM 15:

These countries will only accept properly treated and marked WPM under a marking system of the exporting country. To make your WPM suitable for international shipment, it must be marked with the HT or MB treatment mark. To apply the mark, your facility (i.e. pallet manufacturing or recycling, pest control, cargo forwarding, export brokerage) must be certified by an inspection agency. These agencies provide inspection and auditing services to certified facilities that use the MB treatment mark. To date, this USDA program has accredited four inspection agencies. All inspection agencies have inspectors all over the nation and here is their contact information:

Unauthorized use of the IPPC logo and MB treatment mark is a violation of trademark laws. Licensed fumigators not registered in this program can still fumigate wood packaging and certify these products on their own but they are not authorized to apply the MB treatment mark or any mark similar to it.
