Nov 20, 2007. /Lesprom Network/. Japanese plywood imports continue to fall, down 33% in Sep 2007 from the same month one year ago, Japan Lumber Reports announced. The continued drop in plywood imports is affected mostly by drops in housing starts, which have dropped to all time lows. Inventories at plywood mills also have not sold their supply of plywood, as buyers are addressing immediate needs only. At the same time, prices for imported plywood are falling. Japan Lumber Reports said that Seihoku group, the largest plywood manufacturer in Japan, was reducing its production in November.
