Committee on Anti-Dumping Practices
Ad Hoc Group on Implementation
QUESTIONS RAISED BY MEMBERS CONCERNING PRACTICAL ISSUES AND
EXPERIENCE IN APPLYING ARTICLE 2.4.2
Note by the Secretariat
At its last meeting, the Ad Hoc Group on Implementation directed the Secretariat to compile
and circulate a list of questions posed by Members in the discussions concerning practical issues and
experience in applying Article 2.4.2.  Based on the written submissions of Members, and the
discussions at the last meeting, the Secretariat has compiled the following list:
1. Is the approach set out in Article 2.4.2 used only to determine the existence of dumping?
2. Is the approach set out in Article 2.4.2 used for reviews, including refunds under Article 9.3?
3. Is the approach set out in Article 2.4.2 used for the determination of the margin for a
provisional measure and for the final determination?
4. What considerations are used in deciding whether to use weighted average-to-weighted
average or transaction-to-transaction approaches?  Is there any priority given to which is used?  What
is the relative frequency for using one or the other?
5. To what extent is a combination of the two approaches used for different periods?
6. If the transaction-to-transaction approach is used, what criteria are applied to ensure that the
transactions chosen for comparison reflect the behaviour of the exporter and the domestic industry,
with respect to such factors as timing, customers, quantities, etc.?
7. Is sampling used in selecting transactions for comparison in the transaction-to-transaction
approach?  On what basis are such samples selected?
8. Can the third option (comparing a normal value established on a weighted average basis with
individual export prices) be used?  If so, what is the relative frequency of use?
9. Which approach is taken to assessing whether an investigation should be terminated because
the margin of dumping is de minimis ?
10. If the transaction-to-transaction approach is used, do all margins, or only their weighted
average, have to be below 2 per cent for the investigation to be terminated on the basis of the marginbeing de minimis ?
11. Can sampling be used when assessing the margin of dumping for determining if it is de
minimis ?G/ADP/AHG/W/94

12. How is "all comparable export transactions" in Article 2.4.2 interpreted when making a
weighted average-to-weighted average comparison? In particular how is "nearly as possible the same
time" in Article 2.4 interpreted and, if an export price falls outside that time period covered by the
period for the calculation of the weighted average normal value, is it discarded?
13. Can sampling be used for the calculation of a weighted average normal value, and, if so, do
all comparable export prices have to be used or only a sample of them?
14. When cost of production methodology is used for determining normal value, is this always
treated as a weighted average normal value?
15. From a practical point of view do transacti on-to-transaction comparisons always start with
normal values and then proceed to choosing comparable export prices, or can the opposite approach
be used?
16. When using a weighted average normal value for comparison, are adjustments to domestic
prices always made before averaging or can they be made after averaging, even where the choice ofdomestic prices is on the basis of sampling? Which is the preferred practice?
17. How are transactions in which export price is higher than normal value treated in a
transaction-to-transaction approach?
