Phytosanitary Certificate
Shipments containing timber compliant with ISPM 15 do not require a phytosanitary certificate or plant passport; the ISPM 15 mark certifies that the timber is in good condition.
Wooden packaging bearing the mark guarantees that it meets the requirements of ISPM 15. A separate treatment or other certificate is therefore not required.
Some countries still require a phytosanitary certificate for the import of loose timber or packaging timber. If this is the case, you can find it under the ISPM 15 international country overview for the relevant country.
