ISPM 15-Compliant Custom Crates for International Shipping

The International Plant Protection Convention's ISPM 15 standard sets out measures for wood-packaging pest risk in international trade. It concerns raw-wood packaging and includes dunnage. Qualifying processed-wood packaging, such as plywood, is outside its scope.

A crate with plywood panels can still contain regulated solid-wood framing or a solid-wood base. Have the complete construction reviewed rather than assuming the panel material determines the status of the whole package.

Ask how compliant packaging will be supplied and how the required mark will be applied. A lumber treatment label and a finished wood-packaging mark are not interchangeable proof of the complete crate's status.

USDA APHIS export guidance describes obtaining treated and marked packaging through authorized programs. Do not make your own mark or assume a statement on an invoice substitutes for the required packaging identification.

During design, leave required marks visible. Keep logos, shipping labels and presentation finishes from covering them.

Give the crate provider the destination country and any transit details. Ask the carrier or customs broker to confirm the requirements for the shipment, including any commodity-specific rules and the current treatment requirements for the route.

• Describe all wood used to enclose, support or secure the cargo.
• Identify whether the shipment will be unpacked or repacked en route.
• Confirm who checks the completed packaging before pickup.
• Keep shipment records and clear photographs of the finished crate.
• Recheck requirements when a crate is redirected to a different destination.

An ISPM 15 mark does not establish a load rating, cushioning performance or weather resistance. The design still needs suitable support points, internal restraint and protection for vulnerable surfaces.

For artwork or sensitive equipment, provide the manufacturer's or conservator's instructions. Plan the opening sequence and receiving equipment. Branding and an attractive finish can be considered after these practical requirements are resolved.

Inspect the crate's condition and tell the provider about repairs, replaced components or a changed load. Do not assume that an old mark settles the compliance of a modified crate.

The IPPC implementation resources cover reuse and repair. Have an appropriate provider assess the package and any treatment or marking work needed before the next international trip.

Compliant wood packaging can address one avoidable source of border problems. It does not guarantee customs clearance, prevent every pest problem or replace the cargo's shipping documents.
