Yes. In the case of movement of wooden packaging between third countries (non-EU) or between the European Union and third countries, in both directions, the International Standard for Phytosanitary Measures No. 15 applies.That is, it is mandatory that the "IPPC logo" mark appears on the packaging material, attesting to the treatment.
This standard was established within the Food and Agriculture Organization (FAO) through the International Plant Protection Convention and applies to packaging made of any type of wood — having been adopted, safe for a few exceptions, by all countries. Therefore, packaging that does not comply with this requirement is considered illegal and must be destroyed or treated, and the official phytosanitary services of the dispatcher countries must be notified of the occurrence by the carrier.
