Open Data

Welcome to USITC Open Data home.

Open data refers to publicly available data structured in a way that enables data to be discoverable and usable by end users. The Administration has taken steps to make government-held data more accessible to the public for innovation and economic growth. On May 9, 2013, the President signed an executive order that made open and machine-readable data the new default for government information. Making information about government operations more readily available and useful is core to the promise of a more efficient and transparent government. Explore our open data catalog at, which uses the common core metadata schema for federal agency open data listings.

The following data sets are currently accessible via download:

Investigation Data and Document Data - Through its Electronic Document Information System (EDIS), the USITC provides an interface to extract investigation and document metadata via an API through a Representational State Transfer (RESTful) web service to provide key metadata to the user or application calling it. The user may extract investigation data, including all investigations or investigation number or investigation and phase.

Harmonized Tariff Schedule (HTS) of the United States – The HTS comprises a hierarchical structure for describing all goods in trade for duty, quota, and statistical purposes. This structure is based upon the international Harmonized Commodity Description and Coding System (HS), administered by the World Customs Organization in Brussels, Estimated. The data can be exported through a web-based application in either CSV, XML or JSON formats or can be accessed via a RESTful API as JSON output.

Unfair Import Investigation Data under Section 337 – This dataset provides information on investigative proceedings conducted by the USITC under Section 337, which declares the infringement of certain statutory intellectual property rights and other forms of unfair competition in import trade to be unlawful practices. Most Section 337 investigations involve allegations of patent or registered trademark infringement. Other forms of unfair competition, such as misappropriation of trade secrets, trade dress infringement, passing off, false advertising, and violations of the antitrust laws, may also be asserted.  Investigation data since October 1, 2008 is available for download in either JSON or XML format and in an Excel spreadsheet for proceedings prior to that date.

The following data sets will be available by the indicated future date(s):

USITC Trade Data (DataWeb) - DataWeb provides U.S. international trade statistics and U.S. tariff data to the public. All trade data are compiled from official data retrieved from the U.S. Bureau of the Census (an agency within the U.S. Department of Commerce). When using these data, the Commission suggests that the following citation be used: U.S. International Trade Commission Interactive Trade DataWeb (USITC DataWeb), using data retrieved from the U.S. Bureau of the Census (accessed [date data retrieved from DataWeb]). Estimated Availability December 2016
