HT – Heat Treated for wood exports

Since the early 1990s, some of Canada’s principal export markets have demanded that wood products exported from Canada be heat-treated to a minimum core temperature of 56°C for at least 30 minutes, in order to kill all pests that could be associated with wood prior to export.

Under the Plant Protection Act and the Plant Protection Regulations, any product exported from Canada must meet the phytosanitary requirements of the importing country. The Canadian Food Inspection Agency (CFIA) has implemented two export programs – the Canadian Heat Treated Wood Products Certification Program (CHTWPCP) and the Canadian Wood Packaging Certification Program (CWPCP). These allow wood packaging producers, wood packaging heat treatment facilities and wood drying facilities accredited under the CHTWPCP to produce wood or wood packaging materials in accordance with the requirements of International Standard for Phytosanitary Measures (ISPM) No. 15.
