What is ISPM 15?
ISPM 15 is an international phytosanitary standard concerning wooden packaging in international transport. Its aim is to reduce the risk of pest transfer along with wooden packaging. The standard covers wooden packaging made from raw wood and requires the use of approved phytosanitary measures and official marking.
ISPM 15 in 5 sentences
ISPM 15 regulates wooden packaging used in international trade.
It mainly concerns packaging made from raw wood.
It requires the use of an approved phytosanitary treatment.
After meeting the requirements, the packaging is marked with the IPPC mark.
Non-compliance can cause problems at border control.
ISPM 15 in practice – quick table
Question | Answer |
Does the standard apply to solid wood? | yes |
Does it apply to plywood, OSB, particle board, MDF? | no |
Is an IPPC mark required? | yes, for packaging covered by the standard |
Is thin wood up to 6 mm excluded? | yes |
Can non-compliance cause problems in export? | yes |
When does ISPM 15 apply to your shipping crate?
The standard applies to packaging made from raw wood that can serve as a pathway for the spread of harmful organisms. ISPM 15 includes, among others, crates, pallets, dunnage, cable drums, and similar forms of packaging wood made from raw wood.
In practice, this most often applies to:
crates made of boards,
solid wood pallets,
wooden reinforcements,
spacer elements made of untreated wood.
If raw wood covered by the standard is present in the construction, the use of an approved phytosanitary treatment and marking is required. ISPM 15 indicates that compliant packaging wood is identified by an official mark; the standard also clarifies that the use of this marking replaces the need for a phytosanitary certificate for the packaging wood itself.
Summary: if the crate is made of solid, raw wood, the ISPM 15 topic must be checked.
When does ISPM 15 not apply to shipping crates?
This is the most important information for many exporters. The standard excludes, among others, packaging made entirely of processed wood, such as plywood, particle board, OSB, or veneer produced using glue, heat, pressure, or their combination. Packaging made entirely of thin wood with a thickness of 6 mm or less is also excluded.
This means that:
plywood is not subject to ISPM 15,
OSB is not subject to ISPM 15,
MDF and wood-based panels are generally not subject to ISPM 15 if they are processed material compliant with the exemption,
thin wooden elements up to 6 mm are also covered by the exemption.
Short answer: flight cases and boxes made entirely of plywood or other wood-based materials usually eliminate the ISPM 15 issue.

Why do plywood and OSB simplify export?
Wood-based materials are exempt from ISPM 15 precisely because they are processed wood, recognized as free from pest risk under this standard. This simplifies logistics, as there is no need to apply IPPC marking appropriate for packaging made from raw wood.
In practice, this results in:
fewer formalities,
lower risk of error during the first export,
simpler preparation of the box,
greater predictability of the process.
Summary: a well-chosen export box made of plywood is often a safer process choice than a box made of solid wood.
What does the IPPC mark look like and what does it contain?
ISPM 15 provides for an official mark used on compliant wood packaging. The mark consists of a symbol, country code, producer or responsible entity designation, and the code of the treatment applied. The standard explains that this mark is the basis for recognizing that accepted phytosanitary measures have been applied.
In practice, the mark includes:
IPPC symbol,
country code,
manufacturer or plant number,
procedure designation, e.g. HT.
Summary: the mark must be official, durable, and legible on the packaging covered by the standard.
What documents and markings are important in practice?
The most important in practice are:
correct material,
correct labeling, if the standard applies,
consistency of the box construction with export requirements,
avoiding mixing materials without certainty that there is an element subject to the standard in the construction.
ISPM 15 indicates that non-compliance may result in actions by the phytosanitary services of the importing country, and countries control the compliance of packaging wood upon import.
Short answer: when exporting, not only the box itself matters, but also whether the material and labeling comply with the rules applicable to packaging wood.
How to avoid problems at the border?
The simplest way is to choose the box construction so that it does not generate phytosanitary risk from the start. In practice, this often means choosing an export box made from wood-based materials instead of solid wood. ISPM 15 clearly excludes such materials, including plywood and OSB, from the scope of the standard.
Additionally, it is worth:
checking if there are hidden solid wood elements in the box,
adapting the construction for air, sea, or road transport,
using repeatable export solutions.

Most common mistakes
Solid wood box without proper labeling
Effect: risk of problems during inspection.
Mixing materials without verification
Effect: uncertainty whether part of the structure falls within the standard.
Lack of knowledge during the first export
Effect: incorrect selection of the box and nerves during customs clearance.
Assumption that every wooden box works the same
Effect: confusing a solid wood box with a plywood box.
Summary: the greatest risk usually arises not from the standard itself, but from incorrect material selection.
Why is it worth designing an export box according to regulations and logistics?
A good export box should combine:
material compliance,
protection of the equipment,
process repeatability,
simplicity during customs clearance.
This is particularly important for:
exporting machines,
shipping equipment,
transporting high-value devices,
first shipments outside the country.
Short answer: a well-designed box reduces the risk of detention, delays, and costly logistical corrections.
Frequently asked questions
What is ISPM 15?
This is an international phytosanitary standard for wood packaging used in international trade.
Does plywood fall under ISPM 15?
No. Plywood is listed as an example of processed wood excluded from the standard.
Does OSB fall under ISPM 15?
No. OSB is listed among the excluded materials.
Does a flight case require IPPC?
No, if it is made entirely of wood-based materials, such as plywood.
When is the IPPC mark required?
When the packaging is subject to ISPM 15 and has been made from standard-compliant wood packaging.
Is thin wood up to 6 mm also covered?
No. The standard excludes packaging made entirely of thin wood that is 6 mm thick or less.
What happens without labeling?
There may be a finding of non-compliance and actions by the control authorities of the importing country.
Does a solid wood pallet also fall under the standard?
Yes, because pallets are listed among the forms of wood packaging covered by the standard.
How to avoid problems when exporting?
Most often by properly selecting the material and design of the crate at the design stage. Wood-based materials simplify this process.
Can a crate be sent without an ISPM 15 certificate?
Yes, if the standard does not apply to it, e.g., when the crate is made entirely of excluded materials, such as plywood or OSB.
Summary
ISPM 15 is not complicated if you know from the beginning what material the transport crate should be made of. The most important rule is simple: raw wood is subject to requirements, while wood-based materials, such as plywood and OSB, are excluded from them.
