ISPM-15 (International Standards for Phytosanitary Measures No. 15)
ISPM-15 is the international regulation governing the treatment and marking of solid wood packaging materials used in international trade. It requires that wood pallets, crates, and dunnage be heat treated or fumigated to prevent the spread of invasive pests. ISPM-15 is administered by the International Plant Protection Convention (IPPC).
In-Depth Explanation
ISPM-15 was developed in response to the global spread of wood-boring insects through untreated shipping pallets and crating. Notable invasive species that prompted the standard include the Asian longhorned beetle and the pine wood nematode, both of which have caused massive ecological and economic damage when introduced to new regions. The standard applies to all coniferous and non-coniferous solid wood packaging materials greater than 6mm thick, including pallets, crates, packing blocks, drums, and dunnage. Exempt materials include processed wood products such as plywood, particle board, OSB, and veneer, as well as thin wood packaging under 6mm. Compliant wood must bear the internationally recognized ISPM-15 mark, which includes the IPPC logo, the country code, the producer/treatment facility number, and the treatment code (HT for heat treatment, MB for methyl bromide). Non-compliant shipments risk rejection, quarantine, re-treatment at the importer's expense, or destruction at the port. For lumber companies, ISPM-15 compliance is essential for participation in export markets and for supplying wood to packaging manufacturers who serve international supply chains.
Usage Example
Customs held the shipment at the port because several pallets lacked the ISPM-15 mark, requiring the importer to arrange heat treatment before the goods could clear.
