Start with the heat-treatment mark
The most informative mark is the IPPC stamp: a wheat symbol, a country code, a facility number and a treatment code. HT means heat treated. MB means methyl bromide fumigated, which is being phased out worldwide and which we never produce.
If you find an MB stamp on a pallet in your warehouse, it is legal to use but we would not recommend upcycling it into furniture or planters. There is no residue risk in ordinary handling, but there is no reason to choose it for a vegetable bed either.
Pool brands and what they mean legally
Some pallets belong to somebody. Rental pool operators own their pallets outright and mark them clearly — usually by colour and a prominent brand. Those pallets are not yours to sell, dismantle or use outside the pool, even if they arrived at your dock and nobody came back for them.
This catches people out. We will not buy marked rental-pool pallets, and any reputable yard will tell you the same. If you have accumulated them, contact the pool operator; they generally arrange collection.
Euro and EPAL brands
On a compliant Euro pallet, the left outer block carries a railway or EPAL oval, the centre block carries the IPPC stamp, and the right block carries the EUR or EPAL mark with a licence number and production year.
A pallet of Euro dimensions with no brands is just a block pallet. It may be perfectly good, but it will not be accepted into an exchange pool, and it should not be priced as Euro stock.
Our own stamp
We burn a Passport ID into one stringer: PL, four characters, a check character. It links to the pallet's record — species, grade, cycles, repairs, carbon ledger. Anybody can look it up on our site.
We put it on a stringer rather than a deck board deliberately. Deck boards get replaced; stringers are the part of the pallet that persists through repair, which makes them the right place for identity.
What the absence of marks tells you
An unmarked pallet is almost always a domestic one-way pallet built by a local plant for a single customer. Nothing wrong with it. It simply has no export compliance, no pool ownership and no traceability.
If somebody offers you unmarked pallets as export-ready, that is the moment to ask for a treatment certificate. The answer to that question will tell you everything about the supplier.
