Mexico's Oil Tubular Steel Hit with Low-Price Findings
Published Date: 5/13/2026
Notice
Summary
The U.S. Department of Commerce found that Tubos de Acero de Mexico, S.A. (TAMSA) sold certain oil country tubular goods to the U.S. at unfairly low prices from November 2023 to October 2024. They’re also stopping the review for two other companies. This means possible changes in duties soon, affecting importers and sellers of these steel products.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 6 costs, 0 mixed.
Cash deposit rates and 44.93% all-others rate
For shipments of the subject merchandise entered or withdrawn for consumption on or after the publication date of the final results of this review, the cash deposit rate will be the company-specific rate established in the final results, except if the rate is less than 0.50% (de minimis) in which case the cash deposit rate will be zero. The cash deposit rate for all other manufacturers or exporters will remain 44.93%, the all-others rate from the less-than-fair-value investigation.
Certificate required or risk double duties
Importers must file a certificate regarding reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries during this review period under 19 CFR 351.402(f)(2). If an importer fails to file this certificate, Commerce may presume reimbursement occurred and assess double antidumping duties and/or increase antidumping duties by the amount of any countervailing duties.
Automatic assessment at all-others LTFV rate for unknown shipments
For entries produced by TAMSA during the period of review for which TAMSA did not know the merchandise was destined for the United States, Commerce intends to instruct CBP to liquidate those entries at the all-others less-than-fair-value (LTFV) investigation rate if there is no rate for intermediate companies. The all-others LTFV rate referenced in this notice is 44.93%.
Importer-specific and per-unit assessment method
If TAMSA's final weighted-average dumping margin is not zero or de minimis (i.e., not less than 0.50 percent), Commerce intends to calculate importer-specific assessment rates based on the ratio of total dumping for an importer's examined sales to the total entered value of those sales. Where entered values are missing for some sales, Commerce will calculate an importer-specific per-unit assessment rate based on the ratio of total dumping to quantity of examined sales.
TAMSA preliminarily found to dump (1.62%)
Commerce preliminarily determined that Tubos de Acero de Mexico, S.A. (TAMSA) sold certain oil country tubular goods to the U.S. at a dumping margin of 1.62% for the period November 1, 2023 through October 31, 2024. If this finding is finalized, importers of TAMSA OCTG for that period could face antidumping duties equal to about 1.62% of entered value for those entries.
Review rescinded for two exporters
Commerce is rescinding the administrative review for Siderca S.A.I.C. and Vallourec Oil & Gas Mexico, S.A. de C.V. because there were no suspended entries of their subject merchandise during the period November 1, 2023 through October 31, 2024. Commerce will instruct U.S. Customs and Border Protection to assess antidumping duties on appropriate entries at the cash deposit rate required at the time of entry, and Commerce intends to issue the rescission instructions no earlier than 41 days after publication of this notice (published May 13, 2026).
