Certificate of ISPM 15: A Complete Guide for Exporters and Shippers

The ISPM 15 (International Standards for Phytosanitary Measures No. 15) is a globally recognized regulation that governs the treatment of wood packaging materials (WPM) used in international trade. A Certificate of ISPM 15 confirms that wooden pallets, crates, and dunnage have been properly treated to prevent the spread of pests and diseases.

1. What is ISPM 15?

ISPM 15 is a standard developed by the International Plant Protection Convention (IPPC) to reduce the risk of invasive insects and pathogens being transported via wood packaging. It applies to:

• Wooden pallets

• Crates & boxes

• Skids & dunnage

• Other raw wood packaging

Exemptions:

• Plywood, OSB, MDF (engineered wood)

• Wood thinner than 6mm

• Plastic or metal packaging

2. ISPM 15 Certification Requirements

To comply, wood packaging must undergo one of two approved treatments:

A. Heat Treatment (HT)

• Wood is heated to a minimum core temperature of 56°C for 30 minutes.

• Kiln-drying is the most common method.

B. Fumigation (Methyl Bromide – MB)

• Now mostly phased out due to environmental concerns (Montreal Protocol).

• Only allowed in exceptional cases where HT is not feasible.

After treatment, the wood must be marked with the official ISPM 15 stamp, which includes:
✅ IPPC logo
✅ Country code (e.g., US for USA, CN for China)
✅ Treatment code (HT or MB)
✅ Producer’s unique registration number

3. Who Needs an ISPM 15 Certificate?

• Exporters shipping goods on wooden pallets/crates

• Freight forwarders & logistics providers

• Manufacturers of wood packaging

Countries enforcing ISPM 15:
USA, Canada, EU, Australia, China, Japan, South Korea, and over 100 others

4. How to Obtain an ISPM 15 Certificate?

1. Find an IPPC-approved treatment provider (licensed by national plant protection agencies).

2. Submit wood packaging for treatment (HT or MB).

3. Receive the ISPM 15 mark (stamped or branded on the wood).

4. Optional: Get a formal certificate (some buyers require it).

Note: Some countries accept just the stamp, while others (like Australia) may require a Phytosanitary Certificate in addition.

5. Consequences of Non-Compliance

Rejected shipments at customs
Fines & delays
Forced re-export or destruction of goods

6. Frequently Asked Questions (FAQ)

Q1: Is ISPM 15 mandatory for all wood packaging?

✅ Yes, if the wood is untreated raw lumber (not plywood, plastic, or metal).

Q2: How long is an ISPM 15 certificate valid?

The stamp is permanent, but the wood must be in good condition (no re-infestation).

Q3: Can I reuse ISPM 15-certified pallets?

✅ Yes, as long as the stamp is visible and the wood is not damaged.

Q4: What if my pallet has no stamp?

❌ It may be rejected—always check before shipping!

Conclusion

The Certificate of ISPM 15 ensures smooth customs clearance and prevents costly shipment rejections. Always:
✔ Use properly stamped wood packaging.
✔ Verify import country requirements.
✔ Keep records of treatment certificates.
