Commerce Assigns Borusan 4.91% Preliminary Dumping Margin on Turkish Pipe; Tin-Mill Determination Postponed
Commerce Assigns Borusan 4.91% Preliminary Dumping Margin on Turkish Pipe
The U.S. Department of Commerce has preliminarily determined that Borusan's U.S. sales of circular welded carbon-steel standard pipe and tube products during the period May 1, 2024 – April 30, 2025 were made below normal value. The preliminary weighted-average dumping margin is 4.91%.
Procedural Status and Upcoming Deadlines
The determination is not final. The following deadlines apply after Federal Register publication:
| Filing | Deadline |
|---|---|
| Case briefs | 21 days after publication |
| Rebuttal briefs | 26 days after publication (5 days after case briefs) |
| Hearing requests | 30 days after publication |
| Final results (expected) | Approximately 120 days after publication |
The rate established in the final results will govern future Borusan cash deposit requirements. The all-others rate remains 14.74%.
Tin-Mill Products Investigation Postponed
Commerce has separately postponed the preliminary determination in the new Turkish tin-mill-products antidumping investigation from September 16 to November 5, 2026.
Practical Implications
For Borusan and its U.S. affiliate: The company should review affected entries, assess importer-specific assessment exposure, and evaluate whether to submit case briefs challenging the preliminary margin calculation. Reimbursement certificates should be reviewed in light of the preliminary rate.
For U.S. importers and construction-material distributors: Parties importing Borusan pipe should review open entries and assess potential assessment liability if the final rate differs from the preliminary margin. Importers should also confirm whether reimbursement agreements with the exporter are in place and whether they adequately allocate final-assessment risk.
For supply agreement counterparties: Contracts should address final-assessment risk allocation, customs-document cooperation obligations, price adjustment mechanisms, and indemnification provisions in the event that final duties differ materially from cash deposits.
For parties in the tin-mill investigation: The postponement to November 5, 2026 extends the timeline for preliminary margin calculations. Affected importers and exporters should use the additional time to prepare cost and pricing documentation.
