nti-dumping action can have several
negative effects on exporters. An
anti-dumping investigation is rigor-
ous and time-consuming (usually
lasting about a year and a half). Even
if no dumping is ultimately found, the
opening of an investigation can mean
the loss of customers who are often
unwilling to take the risk that their
supplier will have additional duty im-
posed on it when the investigation is
completed, even if reassured that no
dumping is taking place (
