ISPM-15 Export Complete Guide 2026

ISPM-15 export - what the regulation actually requires

ISPM-15 (International Standards for Phytosanitary Measures No. 15) is the international wood packaging regulation that prevents transport of wood-boring pests through international trade. Approximately 180 countries have adopted ISPM-15 as an import requirement. For US exporters shipping wood pallets, wood crates, wood dunnage, wood bracing kits, or any wood packaging internationally, ISPM-15 compliance is mandatory for destinations that have adopted the standard.

This guide covers the full ISPM-15 compliance workflow: when ISPM-15 applies, how heat-treatment works, APHIS registration requirements, IPPC mark coordinates, treatment-cycle log documentation, and specialty considerations for Latin American and Caribbean destinations.

When ISPM-15 applies

• Wood pallets for international export where destination country has adopted ISPM-15.
• Wood crates and wood boxes for international export (same rules as pallets).
• Wood dunnage and wood bracing kits for international container stuffing where destination has adopted ISPM-15.
• Wood pallet collars, wood bins, platform wood for international export.
• Wood spools and wood cable reels for international export (specialty wood packaging).

ISPM-15 does NOT apply to:

• Plastic pallets - ISPM-15 regulates wood packaging only.
• Processed wood products (plywood, OSB, MDF, specialty engineered wood) that have been chemically or thermally processed to prevent pest transport.
• Wood packaging less than 6mm thick - thin wood is exempt from ISPM-15.
• Domestic US shipping - ISPM-15 is an international regulation.

Heat-treatment specifications

ISPM-15 heat-treatment specification: wood core temperature must reach minimum 56C (132.8F) for minimum 30 minutes. In practice, treatment facilities run heat cycles above the minimum (typically 60-70C for 45-60 minutes) to ensure full pest kill through the full wood thickness. Treatment is done in enclosed heat chambers at APHIS-registered facilities.

Alternative to heat-treatment: methyl bromide fumigation (MB) is permitted by ISPM-15 but has largely been phased out in the US (environmental and workplace safety concerns). Heat-treatment (HT) is the standard US practice.

APHIS registration and IPPC mark coordinates

USDA APHIS (Animal and Plant Health Inspection Service) regulates ISPM-15 compliance in the US. Treatment facilities must be APHIS-registered to apply IPPC marks. USP operates an APHIS-registered Florida facility.

IPPC mark coordinates include three required elements:

• IPPC logo (international plant protection symbol)
• Country code - US for United States origin.
• APHIS facility number - unique facility identifier.
• Treatment code - HT for heat-treatment, MB for methyl bromide (phased out), DH for dielectric heating (specialty), SF for sulfuryl fluoride (specialty).

IPPC mark must appear on at least two faces of each pallet or wood packaging unit. No bark on wood - debarked lumber is required under ISPM-15.

Treatment-cycle log documentation

For every ISPM-15 shipment, request treatment-cycle log documentation. Standard treatment-cycle log includes:

• APHIS facility number
• Treatment date and treatment duration
• Treatment temperature (core wood temperature)
• Treatment chamber identifier
• IPPC mark coordinates applied
• Lot or batch identifier for traceability
• Bilingual (English + Spanish) documentation available on request for Latin American and Caribbean destinations

Latin American and Caribbean export specialty considerations

Latin American and Caribbean destinations have specific ISPM-15 enforcement considerations:

• Panama - Panama Canal transit requires ISPM-15 compliance for wood packaging in container cargo.
• Dominican Republic - Specialty enforcement at Caucedo port.
• Brazil - Strict ISPM-15 enforcement; non-compliant wood packaging can trigger shipment hold and re-export cost.
• Mexico - ISPM-15 compliance required for US-origin wood packaging in Mexican-destined shipments; Nogales AZ, McAllen TX, Pharr TX, Laredo TX land crossings also enforce.
• Caribbean nations - Jamaica, Trinidad & Tobago, Barbados, specialty Caribbean destinations all enforce ISPM-15.

For Jaxport (one of the largest US pulp-and-paper export ports), Port Miami, Port Everglades (one of the largest Caribbean container-export ports), Port Tampa, Port Canaveral export to Latin America and Caribbean, bilingual (EN+ES) treatment-cycle log is standard. USP APHIS-registered Florida facility stamps within 1-2 business days.

ISPM-15 cost structure

• ISPM-15 heat-treatment add-on at low volume (one-time orders): $1.50-$4 per pallet.
• ISPM-15 heat-treatment at enterprise FTL volume (5-20 trucks/week): $0.75-$3 per pallet.
• Stamp lead time: 1-2 business days on top of standard build time.
• Treatment-cycle log: Included with shipment, no additional cost.
• Bilingual documentation: Included on request, no additional cost for Latin American and Caribbean destinations.
• Emergency expedite ISPM-15: Same-day or next-day stamping available at premium pricing.

Frequently asked questions

What is ISPM-15?

ISPM-15 (International Standards for Phytosanitary Measures No. 15) is the international wood packaging regulation that prevents transport of wood-boring pests through international trade.

In practice, treatment facilities run heat cycles above the minimum (typically 60-70C for 45-60 minutes) to ensure full pest kill through the full wood thickness. Treatment is done in enclosed heat chambers at APHIS-registered facilities. Methyl bromide fumigation is permitted by ISPM-15 but largely phased out in the US.

What is the IPPC mark and what does it include?

IPPC mark coordinates include the IPPC logo, US country code, APHIS-registered facility number, and treatment code (HT for heat-treatment, MB for methyl bromide, DH for dielectric heating, SF for sulfuryl fluoride). Mark must appear on at least two faces of each pallet or wood packaging unit. No bark on wood - debarked lumber is required under ISPM-15.

Does USP operate an APHIS-registered facility?

Yes - USP operates an APHIS-registered Florida facility for ISPM-15 heat-treatment and IPPC stamping. APHIS facility number is included on treatment-cycle logs with every ISPM-15 shipment. For specific D-U-N-S / CAGE / UEI / APHIS facility number verification, request via the quote form.

How much does ISPM-15 heat-treatment add to pallet cost?

ISPM-15 heat-treatment add-on at low volume (one-time orders): $1.50-$4 per pallet. At enterprise FTL volume (5-20 trucks/week): $0.75-$3 per pallet. Stamp lead time 1-2 business days on top of standard build time. Treatment-cycle log included at no additional cost.

What countries require ISPM-15?

Approximately 180 countries have adopted ISPM-15 as an import requirement. The US State Department and USDA APHIS publish the current adoption list. For specific destination country ISPM-15 adoption status, buyer verifies with destination customs. Major US export destinations with ISPM-15 enforcement include Mexico, Canada, EU member states, UK, Latin America (Brazil, Panama, Dominican Republic, Chile, Argentina, Colombia, Peru), Caribbean nations, China, Japan, South Korea, Australia, specialty destinations.

Does ISPM-15 apply to plastic pallets?

No - ISPM-15 regulates wood packaging only. Plastic pallets are ISPM-15 exempt. However, Latin American and Caribbean destinations in particular still prefer wood - plastic acceptance at receiving customs varies by destination. For Jaxport, Port Miami, Port Everglades export to Latin America/Caribbean, wood is still the default material despite plastic ISPM-15 exemption.

What documentation do I need for ISPM-15 export?

Treatment-cycle log is standard with every ISPM-15 shipment. Log includes APHIS facility number, treatment date, treatment duration, treatment temperature, chamber identifier, IPPC mark coordinates applied, lot/batch identifier for traceability. Bilingual (EN+ES) available on request for Latin American and Caribbean destinations. For enterprise programs with specific destination documentation requirements, specify in the quote form.

What happens if non-ISPM-15 compliant wood packaging arrives at a destination that requires it?

Destinations enforce ISPM-15 compliance at customs. Non-compliant wood packaging can trigger shipment hold, re-export back to origin, destruction at destination (buyer pays), or costly treatment at destination port. Brazil in particular has strict enforcement with high re-export cost. For buyers running international export programs, ISPM-15 compliance is not optional - the compliance cost is a fraction of the non-compliance cost.

Can USP coordinate same-day or next-day ISPM-15 stamping for emergency export?

Yes - emergency expedite ISPM-15 stamping available at premium pricing. For specific emergency ISPM-15 requirements (hurricane restoration international export, specialty emergency specialty component export), specify in the quote form. Standard stamp lead 1-2 business days; emergency expedite same-day or next-day.
