Wood packaging is one of the most common causes of customs delays — yet many businesses still overlook ISPM15 compliance.
If your shipment uses pallets, crates, or dunnage, failing to meet ISPM15 requirements can result in border holds, re-export, or even destruction of goods.
This guide explains everything you need to know to stay compliant and keep your shipments moving.
What is ISPM15?
ISPM15 (International Standards for Phytosanitary Measures No. 15) is a global regulation developed to prevent the spread of pests through wood packaging material (WPM)
It applies to:
- Pallets
- Crates
- Wooden boxes
- Dunnage (loose wood used to secure cargo)
👉 If you are importing or exporting goods using these materials, ISPM15 is mandatory in most countries.
Why ISPM15 Compliance Matters
Non-compliant wood packaging is a major risk in global trade.
🚨 Common consequences include:
- Shipments held at the border
- Goods rejected or re-exported
- Additional treatment costs
- In some cases, destruction of cargo
👉 This is why working with experienced customs agents is critical.

What Wood Packaging is Covered?
ISPM15 applies to most solid wood packaging materials, including:
- Pallets
- Crates
- Packing cases
- Drums
- Pallet collars
- Load boards
What is Exempt from ISPM15?
Not all wood products are regulated.
✅ Exempt materials include:
- Plywood
- OSB (oriented strand board)
- Particle board
- Veneer
- Wood under 6mm thickness
- Cardboard-based packaging
👉 These are considered low-risk for pest transmission.
ISPM15 Treatment Requirements
To be compliant, wood packaging must:
1. Be Debarked
Wood must be stripped of bark (with minor exceptions).
2. Be Treated
Approved methods:
- HT (Heat Treatment): 56°C core temperature for 30 minutes
- MB (Methyl Bromide fumigation)
Understanding the ISPM15 Mark
Every compliant item must carry a valid ISPM15 stamp.
The mark includes:
- IPPC symbol
- Country code (e.g. GB, DE)
- Unique producer number
- Treatment code (HT or MB)
❗ Important:
- Must be clear, permanent, and visible
- Cannot be handwritten
- Cannot use red/orange colours
What Happens if You’re Non-Compliant?
If your shipment fails inspection:
❌ Packaging may be:
- Rejected
- Destroyed
- Re-exported
- Treated at your expense
❌ Entire shipment may be delayed
👉 This is a common issue in UK-EU trade post-Brexit.
Can ISPM15 Packaging Be Reused?
Yes — but with conditions:
- Must remain undamaged and pest-free
- If repaired → must be re-treated and re-marked
- Adding untreated wood = non-compliant
How to Stay Compliant (Practical Tips)
✔ Source pallets from certified suppliers
✔ Always check for a valid ISPM15 mark
✔ Avoid mixing treated and untreated wood
✔ Keep documentation ready for customs
✔ Work with experienced customs clearance agents
