ISPM-15 is the international standard that covers solid wood packaging in global trade. It requires wood packaging — pallets included — to be treated before crossing international borders. Most countries enforce it. Shipments that arrive on non-compliant pallets can be rejected, quarantined, or destroyed at the importer’s expense.

Any of these can invalidate a pallet’s certification even after treatment:

• Adding untreated wood after treatment — extra bracing, dunnage, or blocking — voids the entire shipment’s status.
• Covering the IPPC stamp with labels or paint makes it unreadable at customs.
• Repairing a certified pallet with untreated wood voids it — repairs must use certified heat-treated material.
• Even small patches of bark left on the lumber are grounds for rejection — debarking is a requirement of ISPM-15.
• Storing certified pallets next to untreated wood creates a risk — pests from the untreated wood can migrate over and compromise pallets that were clean when they left us.

Almost. We heat treat new wood, recycled Grade A, and custom builds in any size. The one exception is Grade B recycled — heavier use means they can carry residual contaminants that react when heated. Heat treated pallets do cost more than untreated ones, but for international shipments it’s a compliance requirement, not a choice — and for food, pharma, or long-term storage the durability benefits offset the difference over time. If you’re not sure which grade fits, see our 48x40 Pallets page or Recycled Pallets page for a full breakdown.

The Pallet Pro supplies ISPM-15 certified heat treated pallets in Orlando and throughout Central Florida — available in 48x40 and custom sizes.

Yes. Every heat treated pallet we supply is processed by a certified treatment facility and stamped with an official HT mark before it leaves. The stamp includes a country code, facility number, and treatment method — what customs looks for on arrival.

A valid ISPM-15 stamp has four things: the IPPC wheat symbol, a two-letter country code (US for domestic), a unique facility code, and the treatment code (HT for heat treated). It should be inside a clear border — usually a rectangle — with a vertical line between the IPPC logo and the other info. Watch for these red flags: hand-drawn marks aren’t valid; red or orange ink isn’t allowed — real stamps are in black; and fake stamps usually just don’t have the right elements.

Not on its own. A heat treated pallet stays ISPM-15 compliant as long as no wood components are repaired or replaced after treatment. Once new wood is added, it’s no longer certified and would need to be retreated.

Partly. The process kills larvae and pulls moisture out of the wood, which lowers the conditions that lead to rot. But it won’t stop mold — that comes down to storage conditions more than treatment. If mold is a concern, pallet grade and how they’re stored matter more.

Heat treatment adds to the standard lead time — the pallets go through a treatment process before delivery. Call or use the quote form and we’ll confirm timing for your specific order.

We deliver throughout Orlando and Central Florida — one-time shipments, recurring deliveries, or drop trailers staged on-site. Pickup is available too if that’s easier.
