Use of anti-stain chemical treatments by the western U.S. softwood lumber industry, 1999

We assessed the use of anti-stain chemical treatments within the softwood lumber industry in the western United States through a questionnaire mailed to producing members of the Western Wood Products Association in spring 2000. Responding mills (56% response rate) produced 5.6 billion board feet (BBF) of lumber in 1999, approximately 33 percent of the total production in the western region. Only 9 of the 69 responding mills reported use of anti-stain chemical treatments. The volume of lumber treated by these mills was roughly one-half of their total production, or 478 million board feet (MMBF). According to a 1994 study in the western region, responding mills produced 6.4 BBF, 21 of 106 responding mills used anti-stain treatments, and the anti-stain-treated volume was 913 MMBF. Thus, the use of anti-stain chemical treatments appears to be declining in the western United States.
