Does ISPM 15 apply to all countries?

Over 180 countries enforce ISPM 15. Notable exception: shipments between EU member states don't require it (single phytosanitary zone). But any shipment crossing into or out of the EU does.

What happens if wood packaging is non-compliant at destination?

Three possible outcomes: re-treatment at port (fumigation or heat treatment at importer's cost, $800–2,500), return to origin, or destruction. Plus 3–7 days of delay and potential demurrage charges on the container.

Do plastic or metal pallets need ISPM 15 compliance?

No. ISPM 15 only applies to solid wood packaging. Plastic, metal, plywood, particle board, and other processed materials are exempt.

Does the ISPM 15 treatment expire?

Heat treatment (HT) does not expire — the mark remains valid indefinitely as long as the wood hasn't been repaired with untreated material. However, if the mark becomes unreadable, the pallet is effectively non-compliant.

Is debarking (DB) alone enough for compliance?

No. Debarking is an additional requirement in some cases but it does NOT replace heat treatment or fumigation. A mark showing only DB is not ISPM 15 compliant.

Who is responsible for ISPM 15 compliance — the shipper or the forwarder?

Legally, the shipper/exporter is responsible. Practically, when non-compliant packaging is caught at destination, the forwarder takes the heat from the consignee. Smart forwarders include compliance clauses in their terms and verify before booking.

Can I use recycled pallets for international shipping?

Yes, as long as they carry a valid, legible ISPM 15 mark and haven't been repaired with untreated wood. Recycled pallets are actually the most common source of compliance failures due to worn marks and undocumented repairs.

What about wood packaging for air freight?

ISPM 15 applies to all modes of transport — sea, air, rail, and road. If solid wood packaging crosses an international border, it must be compliant regardless of transport mode.

What Is ISPM 15?

The international standard that governs wood packaging in cross-border shipments.

ISPM 15 (International Standards for Phytosanitary Measures No. 15) is an IPPC regulation requiring all solid wood packaging used in international trade to be treated and marked. The goal: prevent invasive insects and plant diseases from hitchhiking across borders in raw timber.

It applies to pallets, crates, dunnage, skids, and any other solid wood thicker than 6mm. If your shipment touches wood packaging, you need to verify compliance before it leaves the warehouse.

Enforcement varies by country, but the consequences are universal: non-compliant shipments get held, re-treated, or destroyed at destination — and the forwarder is the one fielding the angry phone call.

What It Applies To

Pallets (most common issue)

Wooden crates and boxes

Dunnage and blocking/bracing

Skids and runners

Cable drums / spools

What's Exempt

Plywood / particle board / OSB

Processed wood (veneer, MDF)

Wood thinner than 6mm

Cardboard and paper packaging

Plastic or metal pallets

Approved Treatment Methods

Only two treatment methods are accepted under ISPM 15. Make sure you know the difference.

Heat Treatment (HT)

Wood core temperature must reach 56°C for a minimum of 30 continuous minutes. This is the global standard — accepted everywhere.

Accepted by all 180+ ISPM 15 countries

No chemical residue — safe for food-grade cargo

Permanent treatment (doesn't expire)

Requires certified kiln facilities

Slightly higher cost than MB in some markets

Methyl Bromide Fumigation (MB)

Chemical fumigation with methyl bromide gas. Dosage: 48g/m³ for 24 hours at 21°C minimum. Being phased out globally due to ozone depletion.

Can be done on-site without kiln

Lower cost in some developing markets

Banned by EU, Canada, China, Australia, and others

Cannot be used with food products

Being phased out under Montreal Protocol

Requires re-treatment if modified

Recommendation: Always specify HT treatment. MB is banned at too many destinations to be reliable, and the list of bans grows every year.

Reading the ISPM 15 Mark

Every compliant piece of wood packaging carries a branded or stenciled mark. Here's how to read it.

IPPC Symbol

The wheat/grain logo on the left side. This identifies the mark as an official IPPC phytosanitary mark. Without it, the mark is invalid.

Country Code

Two-letter ISO code (e.g., US, DE, CN). Identifies where the treatment was performed. Must match the treatment facility's registered country.

Producer / Facility Number

Unique number assigned to the treatment provider by their national plant protection organization (NPPO). This is how customs traces accountability.

Treatment Code

HT = Heat Treatment, MB = Methyl Bromide. This is the most critical element for compliance checks. If it says DB (debarked) only, it is NOT compliant.

DB (Debarked)

Optional addition indicating bark was removed. Debarking alone does NOT satisfy ISPM 15 — it must accompany HT or MB treatment.

Example: IPPC logo + US-12345 HT DB = Heat-treated and debarked wood from US facility #12345

Common Compliance Failures

These are the issues that actually cause rejections at port. Check every shipment.

Stamp is faded, partial, or missing

$800–1,500 re-treatment

Rain, friction, or poor branding makes the mark unreadable. Customs treats unreadable marks the same as no mark. Insist on deep-branded (burned) marks, not ink stamps.

Dunnage is non-compliant

$1,000–2,500 + delays

Shipper treats the pallets but throws in raw wood dunnage for blocking and bracing. ALL wood in the container must be compliant — including loose pieces.

Repaired pallet with untreated wood

Full re-treatment required

Pallet was originally compliant but a broken board was replaced with raw lumber. Any repair with untreated wood invalidates the entire pallet.

MB treatment shipped to EU/Canada/China

$1,500–3,000 + 5-7 day delay

Shipper used methyl bromide but destination country banned it. The shipment gets rejected or fumigated again with HT at destination — at forwarder's account.

Using ISPM 15 mark on exempt materials

Plywood and engineered wood don't need marks. Adding a mark to exempt materials can actually trigger inspections because it looks suspicious to customs.

Forwarder's Pre-Shipment Checklist

Run through this before every booking that involves wood packaging.

Confirm all wood packaging (pallets, crates, dunnage) carries a visible ISPM 15 mark with IPPC symbol

Verify treatment code is HT (not just DB). If MB, confirm destination accepts methyl bromide

Check that marks are deep-branded or heat-stamped, not just ink (ink fades in transit)

Inspect dunnage and blocking/bracing — loose wood pieces are the #1 missed item

If pallets were repaired, verify replacement boards are also treated and marked

For EU/Canada/Australia/China: confirm NO methyl bromide treatment was used

Document compliance with photos before container is sealed — this is your proof if disputes arise

Include ISPM 15 compliance requirement in your booking confirmation to shippers
