1. ISPM 15 certification (IPPC “wheat/bug” stamp)

• Confirms solid‑wood packaging (crates, pallets, skids, dunnage) has been heat‑treated or fumigated, debarked, and complies with International Standard for Phytosanitary Measures No. 15.

• Mark is stamped/brand‑burned on the wood and shows the IPPC symbol, country code, facility number, and treatment code (HT or MB); this is the core proof customs look for

2. ISPM 15 treatment record / certificate from the treatment facility

• Internal or customer‑facing document from a certified facility showing when/how the wood was treated, linked to their IPPC mark.

• Used to demonstrate traceability and compliance if customs or an auditor wants more than the physical stamp.

3. Export ISPM 15 compliance statement (in shipping docs)

• A simple statement on the packing list or commercial invoice that all wood packaging is ISPM 15 compliant and marked.

• Supports the physical stamp and helps customs clear the shipment without asking for separate phytosanitary documents.

4. Phytosanitary certificate for wood/wood products (not packaging itself, but related)

• Issued by a national plant‑health authority (e.g., USDA APHIS or foreign equivalent) for certain wood products or lumber, verifying they are free of pests/disease and treated as required.

• Sometimes requested alongside ISPM 15 compliance when a shipment includes raw wood or high‑risk plant material in addition to the crate.

5. CSC certificate (Container Safety Convention certificate)

• Confirms a freight container meets the International Convention for Safe Containers (CSC) standards for structural strength and safety.

• Based on inspections and tests; without a valid CSC certificate/plate, the container is not legally allowed on a container ship.

6. CSC safety approval plate on the container

• Permanent metal plate fixed to the container, showing CSC approval, manufacture data, maximum gross weight, stacking and racking limits, and date of next examination.

• Functions as the on‑container proof of current CSC certification that carriers and terminals visually check.
