Prodaja podobnih plovil na notranjem trgu države izvoznice ali izvozna prodaja tretji državi po cenah, ki so nižje od proizvodnih stroškov na enoto (fiksnih in variabilnih), povišanih za prodajne, skupne in upravne stroške, se lahko šteje za prodajo, ki zaradi cene ne sodi v običajni potek trgovine in se lahko prezre pri določanju normalne vrednosti, samo če je ugotovljeno, da se takšna prodaja izvaja po cenah, ki ne omogočajo povračila vseh stroškov v primernem obdobju, ki bi običajno trajalo pet let.
Sales of like vessels in the domestic market of the exporting country, or export sales to a third country, at prices below unit production costs (fixed and variable) plus selling, general and administrative costs may be treated as not being in the ordinary course of trade by reason of price, and may be disregarded in determining normal value, only if it is determined that such sales are at prices which do not provide for the recovery of all costs within a reasonable period, which should normally be five years.
