2.4 Drying And Sterilization Requirements

Wood may be sold green or dry, however it must be declared as per labeling instructions and method of insect sterilization, if any, must be detailed (See Sections 2.4.4 and 2.4.5). If drying the wood, all of the following requirements must be met for certification.

2.4.1 Location wood was dried will be documented (REQUIRED)

Documentation will include the following information:

• Company name
• Operator name (Optional) Company address
• Company phone number Company email (optional)

2.4.2 The distance traveled to the drying facility shall be documented. (REQUIRED) To meet interim certification requirements, distance traveled may not be available and will therefore not be required.

2.4.3 Drying process being used will be documented, air dried and kiln dried are both acceptable (REQUIRED) To meet interim certification requirements, this information may not be available and will therefore not be required.

• Drying professional must document the trackable tag or SKU of each item to be dried.
• Drying professional may combine multiple logs, pieces or bundled units for drying.
• If merged, drying professional must document every trackable tag or SKU that comprises the resulting combined kiln charge or drying stack.
• If kiln dried, drying professional will record the type of kiln, such as solar, dehumidification, RF kiln, vacuum kiln, or other.
• If declaring as “kiln dried sterilized”, drying professional will record the temperature reached and duration held at that temperature.

2.4.4 The date drying started in kiln will be documented. For air drying, the date item was cut will be the start date of drying. (REQUIRED) To meet interim certification requirements, this information may not be available and will therefore not be required.

2.4.5 The date the wood is determined to be dry will be documented. This will either be the day it comes out of the kiln or, if air dried, the date item reaches the desired moisture content or the recommended time has elapsed, as per Appendix A. (REQUIRED) To meet interim certification requirements, the date is not required, but moisture content category will still be required for labeling.

2.4.6 Method of insect sterilization will be documented, if any.
It is not within the scope of this document to determine the best method of sterilization in a particular situation. However, it is required that the processor declares whether or not sterilization efforts were made and to document the method used. If kiln dried, this will include duration at identified temperature level. (REQUIRED)

2.4.7 When Urban Wood is sold, it must be classified and declared under one of the categories in Appendix A for full disclosure to the customer. (REQUIRED)
