Pipe Probe: Mexican Firms Hit with Dumping Preliminary Results
Published Date: 2/23/2026
Notice
Summary
The U.S. Department of Commerce checked if two Mexican companies sold light-walled rectangular pipe and tube at unfairly low prices from August 2023 to July 2024. They found that Perfiles LM and Regiopytsa did sell below normal value, which could mean extra duties. This review affects importers and could change the money companies owe, with comments open starting February 23, 2026.
Analyzed Economic Effects
5 provisions identified: 0 benefits, 4 costs, 1 mixed.
Preliminary Dumping Margins Published
If you import light-walled rectangular pipe and tube from Mexico, Commerce preliminarily found dumping for the period August 1, 2023 through July 31, 2024. Commerce published estimated weighted-average dumping margins of 11.77% for Perfiles LM and 7.70% for Regiopytsa (other producers shown at 9.66%). These preliminary margins could lead to additional antidumping duties if finalized.
Cash Deposit Rate Rules and All‑Others Rate
When the final results are published, new cash deposit requirements will apply to shipments entered on or after that publication date. The notice says company-specific cash deposit rates will be the rates established in the final results (rates under 0.50% are treated as zero), and the all-others rate will remain 3.76%.
Importer Reimbursement Certificate Requirement
If you import the subject merchandise, you must file a certificate about whether antidumping duties were reimbursed before liquidation of the relevant entries. If you fail to file this certificate, Commerce may presume reimbursement occurred and could assess double antidumping duties.
How Duties Will Be Assessed (Importers)
Commerce will calculate importer-specific ad valorem assessment rates from the ratio of calculated dumping to entered value for examined sales, or a per-unit rate if entered values are missing. If an importer-specific ad valorem rate or a respondent's weighted-average dumping margin is zero or de minimis (less than 0.50%), Commerce will instruct Customs to liquidate without antidumping duties.
Rescission for Listed Companies
Commerce rescinded the administrative review for the companies listed in Appendix II because there were no suspended entries of subject merchandise from them during August 1, 2023 through July 31, 2024. For those rescinded companies, antidumping duties will be assessed at a rate equal to the cash deposit required at the time of entry or withdrawal from warehouse for consumption.

This means no extra duties for Haur Tyi right now, and the review process is moving forward with some deadlines adjusted due to a government shutdown.
