HEAT TREATING

Canadian Heat-Treated Wood Products Certification Program: Directive: D-14-01

  • This program is intended for use by facilities registered in the HT Program. It’s purpose is to ensure that heat-treated wood products meet foreign phytosanitary import requirements.
  • Wood products are a biological material. They play host to many insects, fungi and other organisms that can be categorized as pests in foreign markets.
  • Plant Pathology is the science that studies the causes of plant diseases, the mechanisms by which diseases develop in individual plants and in plant populations, and the ways and means by which plant diseases can be managed or controlled.
  • One challenge facing the lumber industry, is identifying biological pests and mitigating their impact.
  • Heat-treating wood to meet phytosanitary requirements requires lumber to be heated until its internal temperature reaches 56°C for a minimum of 30 minutes in addition to other criteria outlined in the treatment schedule.
  • Heat treated lumber may be marked as HT or be certified by means of a certificate.
  • The CHTWPCP is administered by the CFIA and monitored by CLSAB-accredited agency such as CMSA.

Facilities who register in this program can be grouped into three categories:

  • Heat Treatment: These Primary producers must follow phytosanitary requirements outlined in D-14-01 schedule PI-07. Auditors such as a CMSA inspector, will perform a monthly inspection of kiln charges to ensure compliance within the program. Upon certification of Heat Treatment, the facility may write a certificate or stamp the product with a certified Heat Treatment stamp.
  • Remanufacturer: These facilities process or handle heat-treated lumber. These facilities are able to write certificates and stamp the products with a certified Heat Treatment stamp. Auditors such as a CMSA inspector, will perform a monthly inspection to review documents and any use of HT stamps.
  • Shipper, Broker, Wholesaler, or Office: This registered facility may combine several heat-treated lumber sources under one certificate by showing the chain of custody from the original treatment facility. They do not have stamps or kilns. Auditors are required to audit these facilities quarterly.
