Toad,<br /><br />The effects of the countervailing duty against Canadian softwood lumber mills on US consumers has been complex and confusing at best.<br /><br />The duty itself varies from company to company but averages around 30%, and the US historically imports about 35% of its lumber, traditionally mostly from Canada.<br /><br />One would think that by adding a 30% tariff, it would automatically raise the prices paid by US consumers but the reality is the futures markets for lumber went down in the US. There are many and varied explainations for this, from changing sources of wood (lots of new production coming in from Brazil, Chile, Russia, etc.) to Canadian mills trying to get more efficient to lower their unit cost of production, and actually increasing their output, rather than decreasing it, and flooding the market driving prices down.<br /><br />In any event, the US driving force behind the duties have been several large timeber companies (but not all-Weyco, for example has been anti duty all along) who wanted the government to protect their markets and margins (yet another case of corporate welfare--editorial--this is the real welfare reform we need!)<br /><br />I think what it really shows is that it is difficult to directly manage economic affairs, and when one action is done on one side of the equation, the results are not always easily predictable, and don't always follow a prescribed script.<br /><br />Softwood plywood and OSB has never been part of the softwood lumber issue, and there is no duty on it either way. The recent run-up in prices (3/8" CDX sheathing is currently being sold mill to distributor in truckload quantities at almost $13 a sheet US$, and OSB is even higher than that!) is a little difficult to explain, although with continued low interest rates, housing starts are very strong, and overall production, for a variety of reasons, has not kept pace. What will happen?? no one knows, but I have been trading commodity lumber and panel products for a long time, and markets go up, and markets go down, and that is about all one can count on.
