Held at the Border: What ISPM-15 Pallet Mistakes Cost Georgia Exporters
A bad pallet stamp doesn't cost you the price of a pallet. It costs you $500 to $5,000 to fix the container, storage fees every day it sits, and a customer waiting on freight that isn't moving. USDA intercepted more than 24,000 non-compliant wood packaging shipments in 2025, and none of those got waved through with a warning.
What a held container actually costs
The first bill is the fix. Depending on container size and whether the port lets you treat on site or forces a re-export, that's roughly $500 to $5,000. Storage accrues daily the entire time it's being sorted out, and demurrage doesn't care whose fault it was.
Then the penalties. Repeat or egregious violations have run past $100,000. Some countries skip the negotiation entirely and destroy the packaging — with your product still strapped to it.
None of that is the number that should worry you. The real cost is a customer in Germany whose line is down waiting on your parts, and the phone call where you explain that the holdup was the pallet. We've watched a shipper lose a standing order over a $1,900 fix. That relationship was worth a lot more than the two bucks a pallet somebody saved on untreated wood.
The three mistakes that get freight stopped
The stamped board got replaced. A shop repairs a pallet, swaps out a cracked deckboard, and the board they pulled happened to carry the mark. Now the pallet has one stamp instead of two, or none. Customs doesn't test your wood — they read the mark, and if it isn't there the container stops. We stamp stringers for exactly this reason. Deckboards get replaced; stringers usually don't. Ask any supplier where they put the mark and why.
Somebody assumed kiln dried meant heat treated. These get used interchangeably by people who should know better. Kiln drying is about moisture content — pulling water out so the wood doesn't warp or mold. Heat treatment is about core temperature and hold time: 133°F at the center of the thickest board in the batch, held 30 continuous minutes, and it exists to kill wood-boring pests. A board can be bone dry at 12% moisture and have never been certified a day in its life. Ask for HT specifically, and ask for the stamp.
The dunnage got forgotten. This is the one that catches careful shippers. Every piece of solid wood in that container needs a valid mark — pallets, crates, skids, blocking, bracing, and the scrap 2x4 somebody threw in to keep the load from shifting. Inspectors check all of it. A perfect set of certified pallets won't save you if the bracing is raw lumber off the shop floor.
When you need it — and when you're paying for nothing
186 countries enforce ISPM-15, but it applies to international trade only. Wood packaging crossing a border. That's the whole trigger.
So if you're a Cartersville manufacturer shipping to a distribution center in Savannah, you don't need heat treated pallets. Domestic freight inside the US carries no ISPM-15 requirement. We've picked up accounts paying an HT premium on 400 pallets a month for a supply chain that never left Georgia. Nobody had ever thought to ask.
A few exemptions worth knowing:
- Continental US to Canada — pallets built from wood originating in the continental US or Canada are exempt, provided the import paperwork carries the declaration statement. Hawaii and the US territories are not included.
- Plywood, OSB, particle board, presswood — manufacturing heat and glue already handle the pest risk. No stamp needed.
- Wood 6mm or thinner — exempt.
One more thing worth saying plainly: this spec hasn't moved since 2013. If a supplier tells you the rules just changed and that's why your price went up, the rules didn't change.
