The Commission's DataWeb is an interactive, self-service, Internet-based system that provides access to extensive tariff and trade data.

The system is updated monthly and integrates international trade transactions with complex tariff and customs treatment.

Data are available on a monthly, quarterly, annual, or year-to-date basis and can be retrieved in a number of classification systems, including the Harmonized Tariff Schedule, the Standard Industrial Classification (SIC), the Standard International Trade Classification (SITC), or the North American Industry Classification System (NAICS). A "Commodity Translation Wizard" translates between these classification systems.

The Commission's DataWeb offers data on imports and exports; U.S. import duties, preferential tariff programs, and staged tariff reductions; U.S. trade global region by partner country, and detailed Commission trade database tables.

The DataWeb can be accessed at http://dataweb.usitc.gov.
