Swiff-Train Co. v. United States, 793 F.3d 1355

Background

The International Trade Commission (ITC) investigated imports of multilayered wood flooring from China and found in 2011 that subject imports materially injured the U.S. domestic industry; Commerce had found dumping/subsidies. U.S. importers (Appellants) opposed the injury finding.
The Court of International Trade (CIT) remanded the ITC determination in Swiff‑Train I, directing the ITC to ensure subject imports were a "but‑for" cause of injury given the severe collapse in homebuilding and remodeling demand.
On remand the ITC reopened the record, reaffirmed its affirmative injury determination, and explicitly concluded that "but for" the unfairly traded Chinese imports the domestic industry would have been materially better off during the collapse and recovery.
The CIT sustained the ITC’s remand determination in Swiff‑Train II; Appellants appealed to the Federal Circuit arguing the ITC failed to perform a required counterfactual analysis and improperly relied on discretion and a "substantial factor" approach.
The Federal Circuit reviewed de novo, applying the substantial‑evidence standard to the ITC record and examined whether the ITC was required to use a specific but‑for counterfactual methodology.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the ITC was required to perform a formal but‑for counterfactual (hypothetical) analysis to satisfy "by reason of" causation	Appellants: statute and precedent require an explicit counterfactual ‘‘but‑for’’ analysis comparing actual industry performance with a hypothetical absence of subject imports	ITC/U.S.: statute does not mandate any single methodology; the ITC may use record evidence and conclude but‑for causation without constructing a formal hypothetical model	Held: No categorical requirement for a formal counterfactual model; ITC may satisfy "by reason of" by reasonable causation analysis using record evidence and explanation
Whether the ITC improperly invoked its discretion to evade legal causation standards	Appellants: ITC asserted broad discretion and thus avoided applying judicially mandated causation rules	ITC/U.S.: discretion applies to methodology selection, but ITC remains bound to statutory causation and to provide a reasoned explanation supported by record evidence	Held: ITC correctly stated it has methodological discretion; it nonetheless applied statutory standard and provided a meaningful explanation supported by substantial evidence
Whether the CIT imposed a new "substantial factor" causation test or erred in treating it as sufficient for but‑for causation	Appellants: CIT invented/relied on "substantial factor" test to bypass but‑for requirement and failed to require two‑step analysis (but‑for then substantial factor)	CIT/ITC: substantial‑factor analysis is consistent with precedent and subsumes but‑for inquiry when properly applied and explained	Held: CIT did not impose a new test; substantial‑factor reasoning is consistent with Federal Circuit precedent and can satisfy but‑for requirement if articulated reasonably
Whether the ITC’s remand determination was supported by substantial evidence	Appellants: market demand elasticity and decline make evidence insufficient; lack of formal counterfactual undermines causation	ITC/U.S.: record showed underselling, price depression, market‑share gains by Chinese imports, and adverse effects on the domestic industry; other factors considered and shown not to sever causal link	Held: Substantial evidence supports the ITC’s causation and material‑injury conclusions; the remand determination affirmed
