IPPC Marking Requirements: What Every Machinery Exporter Must Know

What the rule covers

ISPM 15 applies to solid wood packaging material: crates, pallets, skids, dunnage and bracing made from raw timber. It does not apply to processed wood such as plywood, particle board or oriented strand board, because the manufacturing process removes the pest risk. It also does not apply to plastic or metal stillages.

Machinery exporters get caught by the grey area: a plywood crate with solid wood skids underneath. The crate body may be exempt, but the skids are not, and they need their own mark.

What the mark must show

• The IPPC symbol, positioned on the left of the mark.
• The ISO two-letter country code of the treatment provider, for example CN or MY.
• The producer or treatment provider's registration number, issued by the national plant protection organisation.
• The treatment code: HT for heat treatment, MB for methyl bromide, DH for dielectric heating.
• For debarked wood, the letters DB may be added.

Where shipments get held

The most common failure is a mark applied to the crate but not to the pallet it sits on, or a mark that is illegible because it was stamped over a knot or in the wrong ink. Some destinations also reject marks on reconstituted wood that were copied from a supplier's old stock.

The second most common failure is timing: heat treatment is applied, the crate is repaired on site with untreated timber, and the repaired panel carries no mark. Any repair after treatment has to be re-treated and re-marked by a registered provider.

Build it into the loading plan

Treat the mark as a per-SKU attribute, not a last-minute checklist item. When the crate specification is created, record that it is solid wood and needs IPPC, then carry that flag into the loading plan and the export checklist. At the end of the plan you should be able to count the marked crates and compare it with the number of wooden packages in the container.

The tool reminds and records; it does not certify. The mark is issued by a registered treatment provider, and the responsibility for its presence and legibility stays with the exporter.

Related checks that travel with it

Rust prevention for machined surfaces and moisture control for electrical parts are not IPPC requirements, but they fail in the same shipment and the same conversation. A single compliance checklist covering IPPC, rust-proofing, desiccant and packaging labels is easier to enforce than four separate ones.
