Dongbu Steel Co., Ltd. v. United States

The Department of Commerce has employed a technique known as "zeroing" when it investigates a claim that a foreign producer is "dumping" products in the United States at a price below the price in the country of origin. Using zeroing, margins for sales of merchandise sold by a particular exporter at dumped prices are aggregated and margins for sales at non-dumped prices are given a value of zero; the alternative, known as "offsetting," involves aggregating both dumped and non-dumped prices. The statute, 19 U.S.C. 1677(35)(A), refers to calculation of a "dumping margin" equal to "the amount by which the normal value exceeds the export price." Domestic producers read the word "exceeds" as requiring zeroing. The Federal Circuit has previously upheld use of zeroing in both investigation and administrative review. Following a World Trade Organization decision disapproving the practice, the Department began using offsetting for investigations and zeroing in administrative review. The Court of International Trade upheld the practice. The Federal Circuit reversed, holding that the Department had not adequately justified use of two different interpretations of an ambiguous statute.
