PRACTICAL ISSUES AND EXPERIENCE IN APPLYING ARTICLE 2.4.2
Comments by Mexico on Agenda Items of the Ad Hoc Group
on Implementation of the Anti-Dumping Agreement
The following communication, dated 12 March 2001, has been received from the Permanent
Mission of Mexico.

Further to the invitation to Members to submit documents on the methodology of appropriate
comparison for specific circumstances, under Article 2.4.2. of the Anti-Dumping Agreement, Mexico
submits the following comments:
• Mexico's administrative practice for cases covered by Article 2.4.2 of the
Anti-Dumping Agreement has been to calculate , in most investigations, the margin of
dumping applicable to each exporter by the weighted average of the export price
versus the weighted average of the normal value.  This is because such weighted
averages are regarded as the most suitable tool or method for measuring the
behaviour of prices on the markets under examination during the period of
investigation.
• However, the Mexican investigating authority has also used a comparison of the
normal value with the export price on the basis of prices in individual operations, in
other words, the transaction-to-transaction approach, in instances where the product
subject to investigation shows significant changes during the investigation period, as
is the case with agricultural products.  In this way, a comparison of normal value andexport prices on a transaction-to-transaction basis is more useful when the prices of
the product under investigation vary significantly over short periods (e.g. from day to
day or week to week).
• As to the alternative of a comparison of the normal value established on a weighted
average basis of sales on the domestic market of the country of origin with prices of
individual export transactions, the Mexican investigating authority has no empirical
evidence.  Nevertheless, Mexico considers that a calculation made in this way may be
useful for comparing a stable price in the country of origin with volatile export prices
and thus detecting, in the calculation of the margin of dumping, the attitude of an
exporter who sends his exports at dumped prices to specific customers or regions.
