(1) If:
(a) one of the following applies:
(i) there is an investigation under this Part in relation to whether a dumping duty notice or countervailing duty notice should be published;
(ii) there is a review under Division 5 in relation to the publication of a dumping duty notice or countervailing duty notice;
(iii) there is an inquiry under Division 6A in relation to the continuation of a dumping duty notice or countervailing duty notice; and
(b) the number of exporters from a particular country of export in relation to the investigation, review or inquiry is so large that it is not practicable to examine the exports of all of those exporters;
then the investigation, review or inquiry may be carried out, and findings may be made, on the basis of information obtained from an examination of a selected number of those exporters:
(c) who constitute a statistically valid sample of those exporters; or
(d) who are responsible for the largest volume of exports to Australia that can reasonably be examined.
