What the stamp should show
The mark is a bordered box with the IPPC symbol on the left. To its right: JP, a hyphen, the code Ministry of Agriculture, Forestry and Fisheries (MAFF) gave the producer or treatment provider, and the treatment code. Producer code formats differ by country, so check the shape of the code against other marks from Japan rather than against a fixed pattern.
IPPC | JP-[producer code] | HT (layout only; the producer code is a placeholder)
Who authorises the mark in Japan
The IPPC country page for Japan lists the official contact point as Ministry of Agriculture, Forestry and Fisheries (MAFF), registered on 07 Aug 2026. That body, or the agency it delegates to, registers treatment providers and producers and polices use of the mark. Open the IPPC page for Japan for current contact details.

On arrival in the US or Canada
Wood packaging from Japan entering the United States is regulated under 7 CFR 319.40-3; entering Canada, under CFIA directive D-98-08. Both rely on the ISPM 15 treatment and mark. Once the goods are unpacked, surplus pallets from Japan are yours to reuse, sell or recycle, unless they belong to a rental pool.
