What Type of Wood Is Needed for International Shipping Crates (and Where to Find It)

When you’re preparing goods for international shipping, the material you use for your crates is just as important as the way you pack them. Customs agencies around the world have strict regulations on the type of wood allowed for export, and using the wrong kind could mean delays, fines, or even your shipment being refused entry.

Here’s what you need to know about choosing the right wood for international shipping crates — and where to source it.

ISPM-15: The Global Standard for Wood Packaging

Most countries require compliance with ISPM-15 (International Standards for Phytosanitary Measures No. 15). This standard was created by the International Plant Protection Convention (IPPC) to prevent the spread of pests and diseases through untreated wood.

What it means for you:

• Only solid wood packaging that’s been heat-treated or fumigated is allowed for international shipments.
• Approved wood must be stamped with the ISPM-15 mark, showing it meets the standard.
• Plywood, oriented strand board (OSB), particle board, and other manufactured/composite woods are generally exempt because they’re processed at high temperatures during manufacturing.

Types of Wood Commonly Used

When building export crates, you’ll typically see:

• Pine (heat-treated) – Affordable, lightweight, widely available, and strong enough for most industrial shipments.
• Spruce or Fir – Common alternatives to pine, also heat-treated for compliance.
• Plywood – Often used for crate panels since it’s exempt from ISPM-15 and provides good durability at a lighter weight.
• Hardwoods (oak, maple, etc.) – Used when extra strength or high-value protection is required, though they’re more expensive.

*Note: The key isn’t the species of wood, but whether it’s ISPM-15 certified.

What Wood Can Be Used Without Treating?

Not all wood requires fumigation or heat treatment under ISPM-15. Some products are exempt because the manufacturing process already eliminates pests and pathogens. These include:

• Plywood
• Oriented Strand Board (OSB)
• Particle Board / MDF
• Veneer Sheets
• Fiberboard

Because these engineered woods are made from thin layers, chips, or fibers that are bonded under heat and pressure, they’re considered low risk and can be used in international shipping crates without additional treatment.

Where to Find Certified Wood for Export Crates

If you’re building your own crates or working with a fabricator, make sure they source ISPM-15 compliant lumber. Here are some options:

• Lumber Suppliers & Mills – Many sell heat-treated pine and other softwoods that are IPPC stamped.
• Pallet & Crating Manufacturers – Specialized providers already carry certified wood and can build crates to spec.
• Industrial Packaging Companies – These vendors handle both the wood supply and the crating, often offering turnkey export packaging services.
• Local Export Packaging Services – Many freight forwarders and logistics companies partner with crate builders who use ISPM-15 certified lumber.

When sourcing, always ask for documentation or the ISPM-15 stamp on the wood or finished crate to ensure compliance.

Final Thoughts

Using the correct wood for international shipping crates isn’t just about strength — it’s about compliance. By choosing ISPM-15 certified, heat-treated wood (most often pine or plywood), or by using exempt manufactured wood products, you’ll avoid customs issues and keep your freight moving smoothly.

If you’re shipping internationally and aren’t sure where to start, working with a logistics partner or crate manufacturer like Ark that specializes in export packaging is the safest way to ensure your shipment meets global standards.
