ISPM 15 Crates: Essential Guide for International Shipping Compliance

Posted on Today at 12:11 am

ISPM 15 crates are wooden shipping containers treated to prevent pest spread across borders, in line with the International Standards for Phytosanitary Measures No. 15 (ISPM 15). If you export products with wood packaging, compliance is critical to avoid customs delays, fines, or rejections. This guide breaks down ISPM 15’s key requirements, treatment methods, and benefits—and why Express Packing is a trusted source for certified crates.

What is ISPM 15 and Why It Matters

ISPM 15, established by the FAO under the IPPC in 2002, sets global standards for treating wood packaging to prevent pest transmission.

Scope: Applies to solid wood materials >6mm thick (crates, pallets, dunnage, etc.)

Why it matters:

Enforced by 100+ countries
Prevents the spread of wood-borne pests and diseases
Requires certified treatment + IPPC marking
Essential for uninterrupted international shipping

The IPPC Mark (aka “wheat stamp”) is your shipment’s passport—without it, expect rejections or quarantine at customs.

ISPM 15 Treatment Methods

To meet ISPM 15 standards, wood must be debarked, treated, and marked. Below are the approved treatment methods:

Treatment	Requirements	Code
Heat Treatment (HT)	Core temp ≥56°C for ≥30 mins in kiln or steam chamber	HT
Dielectric Heating	Uses microwave or radio frequency energy to heat wood to 60°C throughout; duration varies by equipment and material.	DH
Methyl Bromide Fumigation	MB gas for ≥16 hours; phased out in EU	MB
Sulphuryl Fluoride	Alternative fumigation approved in latest revisions	SF
Debarking	Bark ≤3cm wide or ≤50cm² in area; required before treatment	DB

Most common method? Heat treatment (HT) – environmentally friendly, globally accepted.

Understanding the IPPC Stamp

Each compliant crate must bear a permanent, legible IPPC mark on two opposite sides, showing:

IPPC wheat symbol
Country code (e.g. US)
Facility code (e.g. 0001)
Treatment code (HT, MB, etc.)
Optional: DB for debarking

Do not use: Red or orange ink (reserved for hazardous goods)

Reused crates must be re-treated and re-stamped—partial repairs void compliance.

What Happens If You Don’t Comply?

Shipping non-compliant crates can trigger major issues:

Customs rejection or quarantine
Fines and penalties
Re-exportation or destruction costs
Environmental and legal liability
Loss of trust from clients and freight partners

Bottom line: Cutting corners isn’t worth it. Non-compliance leads to delays, cost overruns, and reputational harm.
