ISPM-15 Export Packaging Guide

What ISPM-15 means for exporters using wooden crates, boxes, pallets, skids and dunnage in international trade: purpose of the standard, heat treatment, IPPC marks, common failures at port, and how wood compliance fits inside a complete seaworthy packaging system.

Direct answer

ISPM-15 is a phytosanitary wood packaging rule, not a full definition of seaworthy packaging.

What ISPM-15 is

ISPM-15 (International Standards for Phytosanitary Measures No. 15) is the global standard that regulates solid wood packaging material (WPM) used in international trade. It requires approved treatment (commonly heat treatment) and official marking so inspectors can verify that pallets, crates, boxes, skids, dunnage and similar wood packaging present reduced pest risk. Without compliant treatment and marks, wood packaging can delay or stop cargo at destination ports.

Scope

What wood packaging ISPM-15 typically covers

National implementations follow the international framework. In practical export language, solid wood used to support, protect or carry cargo is in scope when used as packaging material, including:

Pallets and skids used under cargo units.

Crates and wooden boxes that enclose or frame cargo.

Cases and bins built from solid wood members.

Dunnage and wood used to brace or secure cargo when it is packaging material.

Load boards, reels and similar wood packaging forms depending on construction.

Paper products are outside the solid-wood packaging concept. Plywood, OSB and some engineered panels may follow different treatment expectations than raw solid wood; always verify the construction and destination rules rather than assuming exemption. When solid wood blocks are added to a plywood case, those solid pieces still need compliant treatment and marking logic.

Treatment and marking

What exporters must see on the wood

RequirementBuyer meaning
Approved treatmentWood packaging material treated under an approved phytosanitary method. Heat treatment to the ISPM-15 profile is the common commercial path.
Official markA legible mark identifying treatment and the authorised producer/system so inspectors can verify compliance.
Debarking / bark rulesWood packaging material must meet bark-related requirements in the standard and national rules.
Repairs and reassemblyRepaired wood packaging must not reintroduce untreated solid wood without correct treatment and marking discipline.

Mark visibility matters

A treated pallet with a paint-covered or missing mark can still fail inspection. Marks should remain readable after packing, weather exposure and handling. Place marks where inspectors can find them without dismantling the cargo.

Exporter practice

How to specify ISPM-15 without process gaps

1. Write it into the packing instruction

“All solid wood packaging material ISPM-15 treated and marked” should be an explicit line, not tribal knowledge on the shop floor.

2. Control repair wood

Field repairs with scrap lumber are a classic failure. Only compliant material enters the pack.

3. Include dunnage and braces

Internal wood braces and temporary dunnage are still wood packaging material when they travel with the cargo.

4. Keep certificates when requested

Some buyers and routes want treatment documentation in the shipping file even when the mark is present.

5. Do not stop at wood

ISPM-15 clears phytosanitary wood risk. Corrosion and moisture still need their own layers.

6. Align with full seaworthy design

Use ISPM-15 timber inside a complete system: seaworthy packaging system.

Boundary

What ISPM-15 does not make true by itself

MythReality
“ISPM-15 timber is automatically seaworthy.”ISPM-15 is phytosanitary compliance for wood packaging. Seaworthy systems also need structure sizing, moisture control, corrosion control and documentation.
“Any stamped wood is strong enough.”Treatment mark is not a structural rating. A light pallet can be ISPM-15 compliant and still collapse under a multi-tonne machine.
“Plastic pallets remove all export packing issues.”Plastic can avoid solid-wood ISPM-15 for that component, but metal still needs corrosion and moisture design, and other wood may remain in the pack.
“Domestic untreated wood is fine if the container seals.”Destination phytosanitary rules apply to wood packaging material in international trade regardless of how well the container seals.

Frequently asked

ISPM-15 search-matched FAQs

What is ISPM-15 packaging?

Wood packaging material used in international trade that has been treated and marked according to ISPM-15 so it presents reduced plant pest risk and can clear phytosanitary inspection.

Do export crates need to be ISPM-15 compliant?

If the crate uses solid wood packaging material in international trade, yes: treatment and marking requirements apply. Confirm construction and destination rules for every solid wood component.

Is heat treatment the only ISPM-15 method?

Heat treatment is the widely used commercial path. The standard framework defines approved treatments; use only authorised methods and marking systems for the material you ship.

Does ISPM-15 apply to plywood boxes?

Plywood and some manufactured wood products may be treated differently from solid wood under the standard’s scope. Solid wood skids, braces or dunnage added to a plywood case still need compliant handling. Verify the full assembly.

What happens if wood packaging is not ISPM-15 compliant?

Destination authorities may delay cargo, require treatment, refuse entry of the wood packaging, or impose other measures. Cost and schedule risk fall on the shipment.

Is ISPM-15 the same as seaworthy packing?

No. ISPM-15 is one compliance layer for solid wood packaging. Seaworthy packaging also addresses moisture, corrosion, structure and documentation. See what is seaworthy packaging.

Do I need certificates in addition to the mark?

Many shipments clear on the mark alone. Some buyers, routes or audits still request treatment documentation. Keep records when the commercial file requires them.

Can I repair an ISPM-15 crate with any timber?

No. Repair materials that are solid wood packaging material must meet treatment and marking rules. Uncontrolled scrap wood is a common audit failure.

Need ISPM-15 timber inside a complete export pack?

Specify cargo, destination and voyage mode. Compliant wood packaging should sit inside a full seaworthy system with corrosion control, desiccant and documentation, not as a stamp-only purchase.
