Public angst over China’s rise and the threat of populist currency legislation have prompted speculation about a U.S.-China “Trade War.” With the 2012 elections still a whole year away, there is ample opportunity for campaigning politicians to ignite that fuse.

But pyrotechnics aren’t necessary. Rather than a 1930s-style free-for-all, a trade war—if one were to begin—is more likely to be of the lowercase, “rules-based” variety, where trade restrictions are imposed in compliance (or under the pretense of compliance) with global trade rules. Many of the battles would be waged behind the façade of so-called trade remedy laws.

Antidumping and countervailing duty measures are the most commonly invoked forms of “contingent protectionism” permitted under World Trade Organization rules. Those rules allow member governments to maintain and administer national antidumping and countervailing duty laws to remedy—through the imposition of customs duties—the effects of imports determined to be sold at unfairly low prices (antidumping) or determined to be unfairly subsidized by a government (countervailing). But imposing “remedies” under these laws is contingent upon certain conditions being met. Two core conditions are that the administering authorities need to demonstrate that the imports in question are being dumped or subsidized, and that those dumped or subsidized imports are causing or threatening material injury to the domestic industry.

A determination expected tomorrow from the U.S. International Trade Commission offers a case in point. The Commission will vote on the question of whether dumped and subsidized imports of multilayered wood flooring (MLWF) from China are causing or threatening material injury to the U.S. MLWF industry. An affirmative determination could invite Chinese retaliation because the evidence of a causal connection between imports from China and injury to the U.S. industry is weak to non-existent. If the U.S. government is going to stretch or skirt the evidentiary standards established by domestic law and international treaty, the Chinese government may be inclined to do the same. (In fact, the Chinese government is already alleged to have broken those rules – and the United States is seeking recourse in the WTO – when it imposed antidumping and countervailing duties on U.S. chicken exports in 2010.)

Multilayered wood flooring is a floor covering product—used for the same practical purposes as hardwood flooring, tile, and carpeting. Sales of MLWF are highly dependent upon new housing starts and remodeling expenditures, both of which tanked when the housing bubble burst in 2008. As a result of U.S. housing starts declining from a seasonally adjusted annual rate of 1.1 million units in February 2008 to just 505,000 units in March 2009, as well as the large decline in remodeling activity over the same period, MLWF industry prices, shipments, revenues, and profits declined substantially, as did imports from China and other countries. But since the second quarter of 2009, housing starts have been stable at about 600,000 units per year and remodeling activity has been steady at about $112 billion per year.

Importantly for the injury analysis, this period of stability in housing starts and renovation activity enables an analysis that isolates the effects of imports on the domestic industry. And what is evident is that, as domestic consumption of MLWF picked up, so did U.S. imports, producer shipments, revenues, and profits (from -9.9 percent in 2009 to -1.0 percent in the first half of 2011). Increasing volumes of subject imports correlate with an improving condition of the domestic industry. Throughout the period of stabilization, prices in the U.S. market have been steady, as well. If imports from China were to have an injurious effect on the domestic industry, one would expect the increasing volume of such imports to drive down prices in the United States. But imports from China, on average, do not underprice domestic MLWF. According to the public version of the USITC Staff Report in this matter:

…prices for MLWF from China were below those for U.S.-produced MLWF in 60 of 110 instances; margins of underselling ranged from 1.5 to 36.4 percent. In the remaining 50 instances, prices for MLWF imported from China were above those for U.S.-produced MLWF; margins of overselling ranged from 0.1 to 30.4 percent.

An affirmative finding of injurious dumping and/or subsidization from the USITC tomorrow would require disregard of these and other crucial facts and would warrant closer scrutiny of the antidumping regime. It would also invite similar actions from Chinese trade remedies authorities and then who know where it will lead.
