The product/process distinction is used by the World Trade Organization (WTO) as a way to determine whether or not a complaint filed by an importing nation is valid and warrants trade barriers against the exporting nation. Under WTO rules, an importing nation can lodge a complaint with the WTO that the exporting nation uses methods for obtaining or producing the good in question that the importing nation finds to be immoral or unethical.[citation needed] If the independent World Trade Organization Advisory Board, made up of a panel of international law and trade experts, finds that the importing nation has a legitimate complaint, enforces said ethical standards for domestic production, and isn't trying to merely skirt its free trade obligations, then the Board will rule that trade barriers are justified.[citation needed] Despite what World Trade Organization officials have said, in practice the World Trade Organization finds these complaints illegitimate the vast majority of the time.[citation needed]
