ISPM 15 Wood Packaging Requirements
What every forwarder needs to verify before cargo hits the port.
What Is ISPM 15?
The international standard that governs wood packaging in cross-border shipments.
ISPM 15 is an IPPC regulation requiring all solid wood packaging used in international trade to be treated and marked.
It applies to pallets, crates, dunnage, skids, and any other solid wood thicker than 6mm.
Enforcement varies by country, but the consequences are universal.
What It Applies To
What's Exempt
Approved Treatment Methods
Only two treatment methods are accepted under ISPM 15.
Heat Treatment (HT)
Wood core temperature must reach 56°C for a minimum of 30 continuous minutes.
Methyl Bromide Fumigation (MB)
Chemical fumigation with methyl bromide gas. Being phased out globally due to ozone depletion.
Recommendation: Always specify HT treatment. MB is banned at too many destinations to be reliable.
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.
Country Code
Two-letter ISO code (e.g., US, DE, CN).
Producer / Facility Number
Unique number assigned to the treatment provider.
Treatment Code
HT = Heat Treatment, MB = Methyl Bromide.
DB (Debarked)
Optional addition indicating bark was removed.
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.
Stamp is faded, partial, or missing
$800–1,500 re-treatmentRain, friction, or poor branding makes the mark unreadable.
Dunnage is non-compliant
$1,000–2,500 + delaysShipper treats the pallets but throws in raw wood dunnage.
Repaired pallet with untreated wood
Full re-treatment requiredA broken board was replaced with raw lumber.
MB treatment shipped to EU/Canada/China
$1,500–3,000 + 5-7 day delayShipper used methyl bromide but destination country banned it.
Using ISPM 15 mark on exempt materials
Adding a mark to exempt materials can trigger inspections.
Forwarder's Pre-Shipment Checklist
Run through this before every booking that involves wood packaging.
Confirm all wood packaging carries a visible ISPM 15 mark with IPPC symbol
Verify treatment code is HT (not just DB)
Check that marks are deep-branded or heat-stamped, not just ink
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
Include ISPM 15 compliance requirement in your booking confirmation to shippers
