ISPM 15 is the standard for wooden pallets and packaging in international trade, and it requires heat treatment or fumigation plus a stamp on the wood. A pallet that is not ISPM 15 marked can be held or rejected at the border.
What ISPM 15 does
ISPM 15 is the International Plant Protection Convention standard for solid-wood packaging. It requires the pallet or the wood packaging to be heat-treated or fumigated, and then stamped, so pests are not moved across a border. A pallet without the mark is not compliant.
Compliance options
| Option | What it does | Why it matters |
|---|---|---|
| Heat treated | Kiln or heat | Marked HT |
| Fumigated | Methyl bromide | Marked MB |
| Stamp | IPPC mark | The compliance proof |
Confirm the pallet is heat-treated or fumigated and carries the IPPC stamp. A pallet without the mark is not compliant and can be held at the border. Confirm the mark is on the pallet, not a document, because the stamp is the proof.
For a US-market import, the wood packaging rule applies, so confirm the pallet meets it.
See the US Federal Trade Commission on commercial claims for the accuracy behind a compliance claim.

FAQ about ISPM 15 and fumigation
What is ISPM 15?
The International Plant Protection Convention standard for solid-wood packaging, which requires heat treatment or fumigation and a stamp on the pallet.
Why does a pallet need the mark?
Without the IPPC stamp, the pallet is not compliant and can be held or rejected at the border. The stamp is the proof.
Is heat treatment or fumigation better?
Either meets ISPM 15. Heat treatment is marked HT and fumigation is marked MB. Confirm the documentation.
Is the mark on the pallet or the document?
The mark is on the pallet. A document alone is not enough, because the stamp on the wood is the compliance proof.
