Requirements for Canadian firewood of all species, as well as spruce logs (Picea spp.), have been applied at all Canada-United States points of entry. The United States Department of Agriculture (USDA) requirements were published to prevent invasive forest pests, such as the brown spruce longhorn beetle, from being introduced into the United States.

Failure to comply with these requirements may result in shipments being rejected at the border.

Firewood

  • All softwood (coniferous) firewood from Canada must be heat-treated to a core temperature of 56°C for 30 minutes.
  • All hardwood (non-coniferous) firewood from Canada is currently regulated on entry into the United States. The heat treatment requirement for hardwood (non-coniferous) firewood has changed. The former core temperature requirement of 71.1°C for 75 minutes has been reduced to 60°C for 60 minutes.
  • A document titled "Heat Treatment Certificate Using a Kiln Facility" prepared by the treatment facility or exporter must accompany all commercial shipments of firewood. The document may be obtained in the Canadian Border Agricultural Clearance Manual.
  • A treatment label must be affixed to the packaging of the firewood or a "Heat Treatment Certificate using a Kiln Facility," produced by the treatment facility or exporter, must accompany all non-commercial shipments of firewood.

Spruce logs

  • Spruce logs from Nova Scotia
    • These logs must be heat-treated to a core temperature of 56°C for 30 minutes.
    • These logs must be accompanied by a valid import permit (issued by the USDA to the US importer).
    • A document titled "Heat Treatment Certificate Using a Kiln Facility," prepared by the treatment facility or exporter, must accompany all shipments. The document is found in the Canadian Border Agricultural Clearance Manual.
  • Spruce logs from areas of Canada other than Nova Scotia require an industry-issued certificate of origin.
