Heat-Treated Wooden Case

Heat-Treated Wooden Case refers to wooden packaging boxes that have undergone heat treatment (HT), meaning the wood is heated to a core temperature of at least 56°C for a minimum of 30 minutes to kill pests such as the pine wood nematode. According to the International Standards for Phytosanitary Measures No. 15 (ISPM 15), all solid wood packaging materials (including wooden cases, pallets, and dunnage) must be heat-treated or fumigated before cross-border transportation and marked with the IPPC logo. Usage scenarios: When exporting to countries with strict requirements such as the EU, USA, Canada, and Australia, heat-treated wooden cases must be provided; otherwise, goods may be returned, destroyed, or fined. Precautions: Heat-treated wooden cases must bear the IPPC stamp, country code, treatment provider code, and HT mark; after treatment, they should be protected from re-infestation and stored in a dry, clean environment; unlike fumigated wooden cases (MB), heat treatment leaves no chemical residue and is more environmentally friendly, but costs slightly more and requires specialized equipment. Foreign trade practitioners should explicitly require suppliers in contracts to provide heat treatment certificates and photos of IPPC markings, and verify their validity.
