How to read ISPM 15 pallet markings

The IPPC symbol identifies the standard’s marking system. The two-letter country code identifies the country under whose authority the mark is applied; the provider identifier is assigned under that authority, and the treatment code identifies the approved measure. HT means conventional heat treatment, not a safe working load.

Look for a legible, permanent, non-transferable mark within its border, with the symbol separated from the codes. The standard requires visibility, preferably on at least two opposite sides. A stencil-like image, incomplete code or appearance of dry timber is not proof by itself.

Read the mark alongside current condition and any repair history. Multiple old marks can make provenance harder to establish; ask the supplier or authorised provider to resolve unclear or conflicting marks. Do not add a mark yourself or reproduce the illustration as a stamp.

Photograph marks clearly for an order discussion, but check that the marks are readable on the actual pallets before loading. Pack so inspection is possible where the shipment process requires it.

Used pallets can contain repaired or replaced boards, blocks and bearers. That history matters. Ask whether the destination or customer restricts repaired packaging and review official guidance on repaired, remanufactured or altered wood packaging rather than assuming the original mark covers every later change.

Check for split or missing components, projecting nails, contamination and damage as separate condition issues. A readable mark does not make a damaged pallet operationally suitable, and a structurally sound appearance does not supply missing compliance evidence.

Provide clear mark photographs, top and underside views, dimensions, repair details if known, quantity, destination country, required treatment or marking, customer specification and requested date. Where pallets vary, check the relevant quantity rather than relying on one sample mark.

Use the live GOV.UK and UK Plant Health Portal guidance for current requirements. We can then discuss already treated and correctly marked used pallets or registered-partner treatment against the shipment brief.
