Background
Tianjin Magnesium International Co. and Tianjin Magnesium Metal Co. challenged the Commerce Department’s final results in an administrative review of the antidumping-duty order on pure magnesium from China. The review covered May 1, 2022, through April 30, 2023.
In March 2026, the Court of International Trade sustained Commerce’s determination in part and remanded it in part. The court concluded that Commerce had erred in finding that Bulgaria did not produce identical merchandise during the period of review, but held that the error was harmless because Commerce reasonably determined that Turkish data were superior. The plaintiffs sought reconsideration, arguing that the earlier opinion contained inconsistent and contradictory findings.
The Court’s Holding
The court denied reconsideration. Because the March opinion was not a final judgment, the court treated the motion under USCIT Rule 54(b), rather than Rule 59(a). Reconsideration may be warranted for reasons such as a change in controlling law, new evidence, clear factual or legal error, or manifest injustice, but it is not a vehicle for relitigating arguments.
The court rejected the claimed contradiction as a misreading of its earlier opinion. Evidence establishing Bulgaria as a producer of identical merchandise consisted of export data, while the Bulgarian production evidence cited by the court concerned an aluminum company’s capacity to make flat-rolled and extruded aluminum products outside the order’s scope. The latter therefore could accurately be described as production data for “arguably comparable merchandise.”
Because production data and export data are distinct, the court concluded that the plaintiffs had improperly conflated them. The motion identified no inconsistency requiring the court to revisit its conclusion that Commerce reasonably selected the Turkish data.
Key Takeaways
- A motion to reconsider a non-final Court of International Trade ruling is evaluated under USCIT Rule 54(b), not Rule 59(a).
- Export data showing that a country produced identical merchandise are analytically distinct from evidence concerning a producer’s manufacturing capacity.
- Reconsideration cannot be used merely to relitigate an argument or obtain another chance to challenge an unfavorable ruling.
Why It Matters
The decision underscores the importance of identifying precisely what each record source proves in antidumping proceedings. Evidence that exports occurred does not necessarily supply the same information as production data used to compare potential surrogate sources.
It also illustrates the demanding standard for reconsidering an interlocutory trade ruling: a party must show a genuine basis for correction, not simply reframe a disagreement with the court’s treatment of the administrative record.
