Pallets, Crates and the Stamp: The Wooden Packing That Can Stop a Shipment

Customs officers are not suspicious of your product. They are suspicious of the wood around it, because timber has carried pests across borders often enough to justify a global rule. That rule shows up as a mark on the packaging, and a shipment can be held on the packaging while the goods inside are perfectly documented. Our pre-crating question list is the practical version of this note.

What the mark is supposed to signal

An ISPM-15-compliant mark on solid wood tells a receiving inspector that the material went through an approved treatment at a facility entitled to apply the mark, and that the treatment is traceable. The mark itself has to be legible, permanent and placed where it can be seen without disassembly. Processed materials — plywood, board, and manufactured alternatives — behave differently from raw timber under the same scheme, and which category your crate falls into is a question about how it was built, not about how it looks. We do not apply the mark and no one should trust a supplier who claims to: it belongs to the treatment facility.

Where an origin warehouse helps

Not by adding paperwork, but by giving you a place to change the packing before it becomes somebody else's problem. A machine that arrives on an untreated timber skid can be transferred to compliant framing in Dongguan or Suzhou while the commercial documents are still being prepared, which is a day of work. The same machine arriving at a destination terminal with the wrong skid is a demurrage invoice and an inspection queue. That is also the moment when a relabeling pass and a photo record get done in one visit instead of three.

Four ways this goes wrong anyway

One: a factory reuses old crates from a previous shipment and the mark has been sanded off or was never on that panel. Two: the mark is present but the treatment date is old enough that a receiving officer questions it. Three: the packing mixes materials — a plywood box on a solid timber skid — and the compliance answer only covers half of it. Four: nobody told the freight layer that the destination applies the rule strictly on that commodity, so the booking is made and the question is asked later. Our China to France lane pages list where wood packing gets examined most, because a lane's habit matters more than the convention's text.

What to settle before the crate is built

Ask the destination broker, in writing, what they will expect to see for your commodity and origin. Decide whether framing is built by your factory or bought at our warehouse and quoted separately, since both routes are normal. Photograph the mark on every unit before the container is stuffed, and keep the photographs with the packing list rather than in a chat thread. If a load is oversized as well as wooden, the crate question and the booking question need answering together, because a frame sized for a standard opening is not the same object as a frame sized for a lift plan.

What you can hand a broker that actually helps

A packing list that names each unit and the material it is built from, the photographs described above, the treatment facility's reference for the mark where one is claimed, and a one-line statement of what the crate is for — permanent transit packaging or a returnable frame. Those four items let an officer close the question instead of opening one. What does not help is a certificate pasted from a previous shipment, or a crate bought second-hand with a mark whose history nobody can restate, and we would rather turn a packing at goods-in than carry that risk onto a terminal.

Small subject, outsized consequences

Wood packing is a low-value topic until it costs a week. The fix costs an afternoon and a set of photographs, and it belongs on the same checklist as the invoice and the commodity code rather than in the warehouse's too-late pile.
