The Administration of the Vocabulary of International Trade: The Adaptation of WTO Schedules to Changes in the Harmonized System

Abstract

A common language is indispensible for reaching and maintaining understanding in all inter-subject relations, including international relations. One element of today's common language in the field of international trade in goods is the Harmonized Commodity Description and Coding System (the Harmonized System/HS) which is maintained by the World Customs Organization (WCO). The HS provides for a common vocabulary by classifying all traded goods according to a nomenclature. This common vocabulary facilitates, and avoids misunderstandings in, communications about products. It thus reduces transaction costs and consequently is of eminent economic importance for today's globalized trade relations. Take for example WTO tariff negotiations with respect to chocolate: While one party might assume that the product commonly referred to as white chocolate is included in the negotiations on chocolate, the other trading partner might assume that it is excluded for the reason that it does not contain cocoa and thus does not qualify as chocolate. Reference during the negotiations to specific positions of the HS nomenclature reduces the probability of such misunderstandings. If during the exemplary tariff negotiations parties would refer to the HS heading Chocolate no party could later claim that the negotiated tariff should also apply to white chocolate since the HS classifies the product which is commonly referred to as white chocolate under the heading Sugar Confectionary (and there under a specific sub-position) whereas chocolate containing cocoa is classified under the heading Chocolate. The vocabulary of the Harmonized System is a point of reference for many legal norms which relate to international trade in goods – in my example the legal obligation to comply with the negotiated tariff concession (Art. II GATT) and not to discriminate against like products (Art. I, III GATT). While the HS provides the vocabulary, these norms provide the grammar of a common language of international trade.
