It is a document which details the general conditions that a seller (exporter) offers to a buyer (importer) for the supply of goods or provision of services. It is used when a seller makes repeated sales to the same customer or for sales of medium and low amounts in which it is not considered necessary to formalize a contract.

The General Conditions of International Sale deal with terms and conditions such as applicable law, warranties, retention of ownership or return of goods. These conditions are commonly found in the reverse side of the sale document (commercial invoice, international purchase order, etc.) with a reference to them on the front side.

The General Conditions of International Sale Guide is helpful for anyone involved in international trade, including: exporters, importers, distributors, traders and brokers, logistics professionals, forwarding agents, shipping lines, airlines, and international trucking firms. This guide is also helpful to trade associations, chambers of commerce, consultants, professors and students of internacional trade.
