ISPM stands for the “International Standards for Phytosanitary Measures”, publication number 15 – Regulations of Wood Packaging Material in International Trade. The regulations are to help prevent the worldwide spread of plant pests and diseases by using specially treated wooden packaging material.

As part of the United Nations Food & Agriculture Organisation (FAO), the International Plant Protection Convention (IPPC) controls the regulations through the cooperation of member governments of the UN. ISPM15 applies to coniferous softwood and non-coniferous hardwood used as raw wood packaging material. The standard does not apply to wood packaging made wholly of manufactured wood-based products such as plywood and veneer, reconstituted wood products (particle board, chipboard, Presswood, oriented strand board, high density fibre board, and medium density fibre board) or products created using glue, heat and pressure or a combination thereof.
All treated WPM will have the IPPC mark as shown.The markings must be within a rectangular border with a vertical line separating the IPPC logo (on the left) from the identifying data.
The border lines may be solid or broken; and the corners may be rounded.

XX – indicates a two letter ISO country code (a link to these may be found on our Links page).
0000 – the next series of letters/numbers is the unique identification mark of the wood treatment agent or packaging manufacturer. The number of letters or digits may vary according to each country.

The country code and treatment agent or manufacturer code must be separated by a hyphen.

YY – This indicates the type of treatment, and will either be HT (Heat Treatment) or MB (Methyl Bromide).

The marking ‘DB’ (indicating debarking has taken place) is no longer used. However, as pallets may last several years, the older style of ISPM15 marking is still permissible.
