UNITED STATES – LAWS, REGULATIONS AND METHODOLOGY
FOR CALCULATING DUMPING MARGINS ("ZEROING")
Request to Join Consultations
Communication from Mexico
The following communication, dated 25 September 2003, from the Permanent Mission of
Mexico to the Permanent Mission of the United States, the Permanent Delegation of the European
Commission and to the Chairman of the Dispute Settlement Body, is circulated in accordance withArticle 4.11 of the DSU.
_______________
Pursuant to Article 4.11 of the Understanding on Rules and Procedures Governing the
Settlement of Disputes, I hereby notify Mexico's substantial trade interest in the above case and ask
that Mexico be joined in the consultations requested by the European Communities (EC) in document
WT/DS294/1/Add.1.
As you know, the measures challenged  by the EC include the following:
(1) The zeroing of negative dumping margins when comparing export prices and normal
values on a weighted average to weighted average basis;
(2) the impact of zeroing negative dumping margins in the determination of the "dumped
imports" in the injury investigation;  and
(3) the determination of dumping margins above de minimis  level as a result of zeroing
negative dumping margins and the consequent imposition of an anti-dumping duty.
The United States is the main destination for Mexican exports, and those exports have been
and may continue to be subject to the measure in question.  It is therefore of the utmost importance
that Mexico should participate in the said consultations.
