What changed

The Secretaría de Economía issued a resolution declaring the start of an administrative review of the antidumping duty imposed on imports of dioctyl phthalate (DOP) originating in the Republic of Korea and the United States.

The review was opened for case EC_18-26; the review period is 1 July 2025–30 June 2026 and the analysis period is 1 July 2021–30 June 2026.

The resolution states the previously imposed definitive duty of 0.27 dollars per kilogram remains in force while the review is processed and that interested parties have 28 business days from the day after publication to register legal interest and submit the prescribed form and evidence.

Immediate operational checks

  • Confirm whether your DOP shipments are classified under TIGIE 2917.32.01 and note the 35% tariff referenced for that heading.
  • If you have legal interest (producer, importer, exporter), prepare and submit the form and evidence to UPCI within 28 business days from 2026-09-02 (deadline counted from day after DOF publication).
  • If applying for electronic submission, send materials to upci@economia.gob.mx (09:00–18:00) or file physically at Calle Pachuca 189 (09:00–14:00).

This resolution announces the initiation of an administrative review; it does not change the numerical duty rate or impose new duties. It does not provide a final determination or termination; outcomes and any modifications to obligations will follow later in the proceeding.
