ISPM-15 Explained: What it is and Why it Matters in 2026

What is ISPM-15 

ISPM-15 is an acronym for International Standards for Phytosanitary Measures No. 15. This measure is a global regulation created by the International Plant Protection Convention (IPPC) to prevent the spread of pests and diseases through wood packaging materials. Untreated wood can contain insects and diseases that can harm agriculture and forestry in foreign environments. ISPM-15 ensures that pallets, crates, and other wood packaging used in international shipping are adequately treated and traceable. 

The Global Reach of ISPM-15 

ISPM-15 was first adopted in 2002 and is now enforced by more than 160 countries, including the world's largest importers and exporters such as the United States, China, India, and the European Union. While most compliant countries implemented the measure in the mid-2000s, some are still adopting it, like Afghanistan in 2020, demonstrating the regulation's global reach. 

Why ISPM-15 Matters for Export Packaging 

ISPM-15 compliance is mandatory for every business participating in global trade. Wood packaging that doesn't meet the standard can lead to immediate consequences, including delays at customs, costly fines, rejected shipments, and even cargo destruction. 

The penalty is worse if non-compliant wood introduces an invasive species. In that scenario, companies may face investigations, trade restrictions, and long-term damage to their brand reputation, not to mention the potential harm to the local ecosystem. 

Compliance not only allows you to ship products across borders but also protects your business, your supply chain partners, and the global environment.

ISPM-15 vs. Standard Heat Treatment 

ISPM-15 applies to all solid wood packaging thicker than 6 mm. It must be debarked, treated, and clearly marked. Acceptable treatments include heat treatment (HT) or methyl bromide fumigation (MB), with an accredited agency verifying the process. 

Although ISPM-15 treatment and general heat treatment utilize the same heat exposure (56 °C for 30 minutes), ISPM-15 requires additional layers of control, including strict bark requirements, a certified and traceable stamp, and formal documentation maintained by the treatment provider and manufacturing facility. This level of oversight ensures that treated materials meet international standards and are safe to introduce into foreign ecosystems. 

Understanding the ISPM-15 Stamp 

ISPM-15 packaging bears a certification stamp, allowing traceability for inspectors at ports of entry. While the format is standardized globally, the content of each marking is unique.  

The stamp includes: 

• Country Code: Identifying the nation where treatment occurred. 

• Treatment Provider or Facility Code: Issued by the National Plant Protection Organization (NPPO). 

• Treatment Method Code: Such as "HT" for heat treatment or "MB" for methyl bromide. 

Because this mark serves as proof of compliance, it must be applied clearly and permanently. Hand-drawn or altered markings are not accepted and may result in automatic rejection at customs. 

Choosing an ISPM-15 Certified Supplier 

Selecting the right supplier is crucial to avoiding compliance issues, especially for businesses shipping high-value products or operating on tight delivery schedules. A reputable ISPM-15 certified supplier will be transparent about its credentials and provide necessary documentation to verify them. 

Before partnering with a supplier, ensure: 

1. Their ISPM-15 certification is valid and issued by an authorized agency.
2. Their pallets, crates, skids, and other wood packaging display the correct ISPM-15 stamp—including the IPPC logo, country code, facility code, and treatment method. 
   

The Future of ISPM-15 Compliance 

The last update to the ISPM-15 standard occurred in 2013. While the IPPC periodically reviews all phytosanitary measures, there is currently no indication of upcoming changes to ISPM-15 for 2026. However, as global trade and ecological risks continue to evolve, staying informed by the IPPC and industry partners remains essential.
