China Corrosion Inhibitors Face Possible New Tariffs

## Summary

The U.S. Department of Commerce found that some Chinese companies sold corrosion inhibitors at unfairly low prices from March 2024 to February 2025. This means these companies might face extra duties to level the playing field for U.S. businesses. The review results are preliminary, and folks involved can share their thoughts before final decisions come later.

## Abstract

The U.S. Department of Commerce (Commerce) preliminarily determines that producers/exporters subject to this review made sales of subject merchandise at less than normal value (NV) during the period of review (POR) March 1, 2024, through February 28, 2025. Interested parties are invited to comment on these preliminary results of review.

## Effects PRIA read

- Preliminary Dumping Margins Assigned: cost, high. Commerce preliminarily found weighted-average dumping margins for subject Chinese exporters for the March 1, 2024–February 28, 2025 period: Anhui Trust Chem/Jiangsu Trust Chem/Nanjing Trust Chem — 61.51%; Nantong Botao Chemical Co., Ltd. — 86.96%; Gold Chemical Limited — 73.75%; Kanghua Chemical Co…

Rules include: (1) companies with a separate rate will have the cash deposit rate set by the final results (unless zero or de minimis); (2)…
- How Commerce Will Assess Duties on Entries: cost, medium. If the mandatory respondents' margins are not zero or de minimis, Commerce intends to calculate importer-specific assessment rates using the ratio of total dumping for an importer's examined sales to the total entered value of those sales. If entered values are missing, Commerce will calculate a pe…
- Importer Reimbursement Certification Requirement: cost, high. Importers must file a certificate regarding reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries under 19 CFR 351.402(f)(2).
