What is ISPM 15?

A standard for wood packaging

ISPM 15 is the International Standard for Phytosanitary Measures No. 15. It addresses the risk of moving timber pests in raw wood packaging used in international trade. Its scope includes wooden pallets and dunnage. It is a plant-health measure, not a pallet strength specification. A pallet can have an appropriate treatment mark and still be unsuitable for the weight, racking system or handling equipment you intend to use.

Three different questions before you buy

Start with the journey: where are the goods being packed, where will they enter another country and where will they finish? Next, specify the pallet as a piece of load-bearing packaging: footprint, cargo weight, support, entry and handling. Finally, specify the relevant treatment and marking. Keeping those questions separate prevents a common purchasing mistake: asking only for an “export pallet” and leaving the actual requirement open to interpretation.

What belongs in your enquiry

Give your supplier the destination country, pallet size in millimetres, quantity, load details, whether the goods will be racked and the delivery postcode. Include the date pallets are needed for packing, rather than only the vessel departure date. If a customer has issued a packaging specification, share it before the pallet is selected. Ask the forwarder to flag any destination-specific conditions or documentation.

What the standard does not promise

ISPM 15 treatment is not permanent protection against reinfestation. Nor should a treatment mark be read as proof that a pallet is dry, clean enough for food contact, free from previous chemical contamination, or structurally sound. Treat the mark as one part of a documented dispatch check. The product, the packaging, the condition and the journey all need to fit together.

What the name means in a purchase order

The initials stand for International Standard for Phytosanitary Measures. Number 15 concerns wood packaging moving in international trade. A useful order therefore identifies both the packaging and its intended movement. “ISPM 15 pallet” is convenient shorthand, but it is not a complete product specification: it leaves the footprint, board arrangement, entry design, condition and loading requirements unresolved.

For example, a buyer sending boxed components may need a different deck arrangement from a buyer sending a machine of the same total weight. Both may need compliant wood packaging on the same route. The treatment requirement is shared; the structural design is not.

Which parts of a shipment to examine

Start with the pallet, then work outwards. Look at collars, cases, battens, bearers, chocks and loose timber that stops movement inside the vehicle or container. A purchase of compliant pallets cannot establish the status of timber added by a separate packing team. Establish who provides each component and include all raw-wood packaging in the pre-dispatch review.

Materials made wholly from qualifying processed wood are treated differently under the standard. The important word is wholly: a case with plywood panels and solid timber runners is a mixed construction. Ask for the material schedule rather than relying on the description “plywood case”.

Who does what

The supplier confirms the packaging offered and its treatment arrangements. An authorised producer or treatment provider applies official marks under its national system. The exporter and importer establish the requirements for the movement, with their freight advisers where appropriate. The packing team checks that the finished assembly matches the agreed plan.

Keep these responsibilities visible on repeat jobs. If a purchasing team changes supplier, a packing team adds timber or a customer changes destination, revisit the relevant part of the specification instead of automatically reusing last month’s instructions.

A practical five-part buying specification

Record the footprint and construction; describe the cargo and its support points; identify every handling stage; specify the destination and wood-packaging requirements; and state the quantity, packing deadline and delivery arrangements. Attach the current drawing when available. A clear enquiry allows quotations to be compared on the same basis.

Do not treat a lower quote as equivalent until condition, treatment, delivery and design have been reconciled. The cost of correcting an unsuitable base after packing can outweigh a modest unit-price saving. That is a purchasing consideration, not a claim that one pallet type is always the better choice.
