The Incoterms® rules or International Commercial Terms are a series of pre-defined commercial terms published by the International Chamber of Commerce (ICC) that are widely used in International commercial transactions or procurement processes. A series of three-letter trade terms related to common contractual sales practices, the Incoterms® rules are intended primarily to clearly communicate the tasks, costs, and risks associated with the transportation and delivery of goods.
The Harmonized Commodity Description and Coding System generally referred to as "Harmonized System" or simply "HS" is a multipurpose international product nomenclature developed by the World Customs Organization. The system is used by more than 200 countries and economies as a basis for their Customs tariffs and for the collection of international trade statistics. Over 98 % of the merchandise in international trade is classified in terms of the HS. The HS is thus a universal economic language and code for goods, and an indispensable tool for international trade.
