International Trade Administration

Through its Trade Developer Portal, the International Trade Administration (ITA) provides APIs to data intended for public use and dissemination. Trade experts from ITA and from Trade Promotion Coordinating Committee (TPCC) agencies produce the wide spectrum of data provided by these APIs. ITA publishes them to help developers access authoritative information on exporting that they can then make available to businesses, which is a core tenet of the ITA. The output for all ITA APIs is JSON.

Available datasets include:

  • ITA’s Market Research Library - The Market Research Library API provides metadata for country and industry reports that are produced by ITA’s trade experts and are available in ITA’s online market research library. ITA commercial officers that are stationed around the world, publish these authoritative reports in conjunction with Foreign Service officers from the State Department.
  • ITA Offices & Center Locations - The ITA Offices & Centers API provides contact and address information for all of ITA’s domestic and international export assistance centers. There are almost 200 ITA centers worldwide whose locations are managed by ITA’s internal office management system.
  • Tariff Rates – The Tariff Rates API provides data about each country with whom the United States has a Free Trade Agreement (FTA). When the U.S. enters into an FTA with a foreign government, it negotiates lower tariff rates with that government for a wide variety of products. A tariff is a tax that a company must pay a foreign country when shipping a product to that country. Typically the FTA tariffs rates decline over several years. Products are indicated by their HS-6 code.
  • Trade Events - The Trade Events API provides data on events for U.S. businesses interested in selling their products and services overseas. These events include industry conferences, webinars, lectures, and trade missions organized by ITA and other trade agencies including the U.S. Trade and Development Agency, State Department and Small Business Administration.
  • Trade Leads - The Trade Leads API provides contract opportunities for U.S. businesses selling their products and services overseas. These leads come from a variety of sources and we continue to expand the number of leads available. ITA currently provides trade leads, procurement opportunities, and contract notifications from the State Department’s Business Information Database System (BIDS), FedBizOps, the United Kingdom, Canada, the Millennium Challenge Corporation and Australia.
  • Zip Code to USEAC - The Zip Code to USEAC API provides direct access to the U.S. Export Assistance Centers (USEACs) that have been assigned to all of the 40,000+ zip codes in the United States. It’s not enough to do a proximity search for a zip code and a USEAC. Each center has specialists on hand for each particular region.
