What is the difference between Kiln Dried (KD) and Heat Treated (HT) lumber?
Kiln dried lumber is heated in kilns to reduce moisture in lumber through evaporation to reduce warping, but may not reach an internal temperature that sterilizes the wood. Heat treated lumber is heated to 56°C for 30 minutes to ensure complete sterilization of the lumber.

How do I find out what company a stamp belongs to?
You can look up the stamp number in our membership directory. You can submit a picture of the stamp via email to info@wclib.org and we will get back to you, typically the same business day.

How is board feet calculated?
Width in inches X length in feet / 12 = board feet Example: 8’ 2x4 = 2 x 4 = 8 / 12 = .666 x 8’ = 5.333 board feet Example: 16’ 2x6 = 2 x 6 = 12 / 12 = 1 x 16’ = 16 board feet

The IPPC is an international treaty to secure action to prevent the spread and introduction of pests of plants and plant products, and to promote appropriate measures for their control.

Examples of WPM materials include, but are not limited to, pallets, crates, skids, containers, boxes, pallet collars, dunnage, drums, bins, cases, etc. Wood Packaging that contains any amount of solid wood components must be treated and marked.
