Commerce Slaps Duties on Mexican Heavy Pipes After Review
Published Date: 3/10/2026
Notice
Summary
The U.S. Department of Commerce found that some heavy walled rectangular pipes and tubes from Mexico were sold in the U.S. at unfairly low prices from September 2023 to August 2024. They’re stopping the review for twelve companies that didn’t ship these products during that time. This could mean changes in duties and costs for importers and manufacturers soon.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 4 costs, 0 mixed.
Preliminary Dumping Margins Announced
Commerce preliminarily found heavy walled rectangular pipes and tubes from Mexico were dumped during September 1, 2023 through August 31, 2024. It preliminarily assigned weighted-average dumping margins of 31.23% for Forza Steel S.A. de C.V., 7.42% for Productos Laminados de Monterrey S.A. de C.V., and a review-specific rate of 16.81% for companies not individually examined.
Cash Deposit Rules After Final Results
When Commerce publishes the final results, cash deposit rates for shipments entered on or after that publication will equal the weighted-average dumping margins from the final results (unless a rate is less than 0.50%, in which case the cash deposit rate is zero). If an exporter/producer lacks a current rate, prior segment rates apply, and the all-others rate remains 4.91%.
Automatic Assessment at 4.91% for Certain Entries
For entries during the POR produced by Forza or Prolamsa where the producer did not know the merchandise was destined for the United States, Commerce will instruct CBP to liquidate those entries at the original less-than-fair-value all-others rate of 4.91% if there is no rate for the intermediate company(ies) involved.
Importer-Specific Assessment Calculation Rules
If Forza or Prolamsa receive a non-zero/non-de minimis dumping margin in the final results, Commerce will calculate importer-specific assessment rates by dividing the total amount of dumping for the importer's examined sales by the total entered value of those sales; if entered values were not reported, Commerce will calculate per-unit assessment rates.
Review Rescinded for 12 Mexican Firms
Commerce rescinded this administrative review, in part, for twelve companies that had no recorded suspended entries during the period September 1, 2023 through August 31, 2024. For those twelve companies (listed in Appendix II, e.g., Ternium S.A. de C.V., Industrias Monterrey, S.A. de C.V., among others), Commerce will instruct CBP to assess antidumping duties at the cash deposit rate that applied at time of entry during the POR; assessment instructions will be issued no earlier than 41 days after publication of this notice.
