What is ISPM-15?
ISPM-15 (International Standards for Phytosanitary Measures No. 15) is an international phytosanitary measure developed by the International Plant Protection Convention (IPPC) to reduce the international spread of disease and invasive species in wood packaging materials.
Purpose
Prevents the spread of invasive pests and plant diseases through wooden packaging materials used in international trade. Protects forests and agricultural systems worldwide.
Requirements
All wood packaging materials (pallets, crates, boxes) made from raw wood must be heat treated or fumigated and marked with an ISPM-15 compliance stamp.
Countries
Over 180 countries require ISPM-15 compliance for imported wooden packaging. Major markets include EU, China, Australia, Canada, Mexico, and most of Asia.
Heat Treatment (HT) Process
Temperature Requirements
Core Temperature: Minimum 56°C (133°F)
Duration: Maintained for minimum 30 continuous minutes
The entire wood package, including the core, must reach and maintain this temperature to effectively kill pests, larvae, and eggs at all life stages.
Monitoring: Temperature probes placed throughout chamber ensure uniform heat distribution and accurate core temperature readings.
Treatment Equipment
Kilns: Large heated chambers designed specifically for heat treatment of wood packaging materials.
Capacity: Our facilities can heat treat hundreds of pallets per day to meet urgent export deadlines.
Certification: Our heat treatment facilities are certified and regularly inspected by USDA and APHIS officials.
Documentation: Complete treatment records maintained for compliance and traceability.
Benefits Beyond Compliance
- Kills Pests: Eliminates insects, larvae, eggs, and wood-boring pests
- Reduces Moisture: Lowers moisture content, making pallets lighter
- Prevents Mold: Lower moisture reduces mold and fungus growth
- Improves Stability: Dried wood is more dimensionally stable
- Extends Life: Treated pallets often last longer
ISPM-15 Marking & Stamps
Proper ISPM-15 Mark
Every heat-treated pallet must bear a clear, legible mark that includes specific required information:
Mark Components:
- IPPC Logo: Stylized wheat symbol in shield
- Country Code: XX (two-letter ISO code, e.g., US)
- Producer Code: Unique identifier for treatment facility
- Treatment Code: HT (Heat Treatment) or MB (Methyl Bromide)
Example: [IPPC Logo] US-NC-123 HT
This indicates a pallet heat treated in the United States, by producer #123 in North Carolina.
Mark Application
Method: Stamps, stencils, or permanent ink branding
Visibility: Mark must be clearly visible on at least two opposite sides of the pallet. Should be easily found during inspection.
Durability: Must remain legible throughout normal shipping and handling conditions. Cannot be easily removed or defaced.
Size: Minimum character height requirements ensure readability by customs inspectors.
Mark Verification
Customs Inspection: Inspectors verify mark presence and legibility at ports of entry worldwide.
Database: Treatment facility codes registered in international database. Customs can verify authenticity.
Consequences of Missing/Improper Marks:
- Shipment delays at customs
- Treatment or fumigation at destination (expensive)
- Rejection and return of shipment
- Destruction of packaging materials
- Fines and penalties

United Kingdom & Europe (Non-EU)
- United Kingdom
- Switzerland, Norway
- Serbia, Ukraine
Exceptions
Domestic Shipping Only: United States internal shipments do not require ISPM-15 treatment.
Always Verify: Requirements can change. Verify current regulations for your specific destination country before shipping.
Alternative Treatments
Methyl Bromide Fumigation (MB)
Process: Pallets exposed to methyl bromide gas in sealed chamber. Chemical penetrates wood to kill pests.
Mark: MB instead of HT on ISPM-15 stamp
Considerations: Being phased out due to environmental concerns (ozone depletion). Many countries restricting or banning MB use. Heat treatment is preferred method.
Dielectric Heating
Process: Electromagnetic energy (microwaves or radio frequencies) heats wood from inside out.
Advantages: Faster than kiln heating, uniform heat distribution, less energy intensive
Status: Approved treatment method under ISPM-15. Marked with DH code. Still relatively uncommon.
Sulfuryl Fluoride (SF)
Process: Fumigation with sulfuryl fluoride gas. Emerging alternative to methyl bromide.
Status: Approved by some countries, pending in others
Considerations: Less widely accepted than heat treatment. Verify destination country acceptance before use.
Exempt Materials
Processed Wood Products
These materials are considered processed and generally exempt from ISPM-15 requirements:
- Plywood: Made from thin veneers glued together
- Particleboard: Made from wood chips/particles
- OSB: Oriented strand board
- Fiberboard/MDF: Made from wood fibers
- Hardboard: Compressed wood fibers
Reason: Manufacturing process (heat, pressure, glue) kills pests. However, always verify with destination country.
Wood Thickness Exemption
Bark-Free Wood Under 6mm Thick: Generally exempt from ISPM-15 treatment requirements.
Reason: Too thin to harbor pests that complete full lifecycle. Most pests require thicker wood to breed and develop.
Note: Must be bark-free. Any bark present requires treatment regardless of thickness.
Alternative Materials
Non-wood materials don't require ISPM-15 treatment:
- Plastic Pallets: No treatment needed
- Metal Pallets: Exempt from ISPM-15
- Cardboard/Paper: No wood, no treatment
- Composite Materials: Check specific composition
Cost Consideration: While exempt, alternative materials often cost more than treated wood pallets.

Common Questions About ISPM-15
Do I need ISPM-15 for domestic US shipping?
No. ISPM-15 is only required for international shipments. Within the United States, heat treatment is not required unless specifically requested by customer.
How long does heat treatment take?
Standard: 1-3 business days including treatment time and scheduling. Rush: Same-day or next-day service available for urgent exports (additional fees apply).
Can I reuse heat-treated pallets?
Yes, as long as the ISPM-15 mark remains visible and legible. The mark stays valid for the life of the pallet unless it's repaired with untreated wood.
What if my pallet is repaired?
If more than 30% of pallet components are replaced with new wood, entire pallet must be re-treated and re-marked. Minor repairs with treated wood maintain certification.
Does heat treatment weaken the wood?
No. Proper heat treatment does not significantly affect wood strength. The kiln-drying process actually makes wood more stable and dimensionally consistent.
What documentation do I need?
We provide heat treatment certification documents with each order. Keep these with your shipping documents. Customs may request verification of treatment.

Frequently Asked Questions
What is ISPM-15 and why is it required?
ISPM-15 is the international standard for treating wood packaging to prevent pest transfer. Most countries require it for wooden pallets and crates entering their borders.
How long does heat treatment take?
The treatment cycle runs until pallets reach the ISPM-15 core-temperature requirement. Most orders are completed within 24-48 hours from scheduling.
Do you stamp pallets after treatment?
Yes. Each compliant pallet is stamped with our ISPM-15 mark and we supply documentation showing batch details and dates.
Can treated pallets be reused for multiple shipments?
Yes, as long as the pallet remains intact and unstamped areas are not removed. If repairs are made, retreatment and re-stamping may be required.
Do you offer both stringer and block pallets with ISPM-15?
We provide ISPM-15 compliant stringer and block pallets in common sizes, and we can treat custom sizes as needed.
How do you verify moisture and temperature?
We monitor kiln temperature and exposure time to meet ISPM-15 standards and document each batch for quality assurance.
Can you heat treat custom-built pallets?
Yes. Custom pallets can be treated and stamped after fabrication so they are ready for international use.
What documents will I receive?
You will receive a treatment certificate with batch details and stamps on pallets. Digital copies are available for your records.
Do you handle mixed loads of treated and untreated pallets?
We keep treated pallets segregated to protect compliance. If you need both types, we stage and label them separately for clarity.
Can you advise on destination-specific rules?
Yes. Tell us your destination country and we will confirm any special marking or documentation details beyond ISPM-15 basics.
