Mexico sets final duty of $0.3918 per kilo on US PVC resin
The duty is lower than the provisional one imposed in March and applies to imports starting Oct. 29.
Mexico's Economy Ministry has set a final antidumping duty of $0.3918 per kilogram on suspension PVC, an industrial resin, in a resolution published Wednesday in the country's official gazette that closes its investigation into imports from the United States. An antidumping duty is a charge that offsets the sale of a product abroad below its normal price.
It takes effect Oct. 29. Mexico's Finance Ministry collects it nationwide, in pesos at the dollar equivalent per kilo, on imports entering under tariff code 3904.10.03 or any other. The general tariff on that code is 3%.
The final figure sits below the provisional duty of $0.6315 per kilo that the ministry imposed in March and later extended to six months. It calculated price-discrimination margins higher than the final duty and concluded that $0.3918 is enough to remove the injury to domestic producers.
| Item | Dollars per kilogram |
|---|---|
| Provisional duty (March 2026) | 0.6315 |
| Final duty | 0.3918 |
| Calculated margin, Oxy Vinyls and other U.S. exporters | 0.72 |
| Calculated margin, Westlake | 0.59 |
The United States supplied 98.1% of Mexico's imports of the product between October 2023 and September 2024, the period under investigation. Over the three-year analysis window ending in September 2024, the investigated imports grew 14% and their price fell 49%. The domestic industry's selling price dropped 50%.
Mexichem Resinas Vinílicas, the petitioner, filed the request on Dec. 10, 2024, and the ministry opened the case on April 28, 2025. Along the way it turned down a price commitment offered by Westlake, one of the U.S. exporters. Economy Secretary Marcelo Ebrard signed the resolution.
The ruling orders the guarantees posted for the provisional duty canceled and any overpayment refunded with interest, measured against the final $0.3918 per kilo.
