U.S. International Trade Commission (USITC)
The U.S. International Trade Commission (USITC) is an independent, bipartisan federal agency with two primary roles relevant to HTS classification: it publishes and maintains the Harmonized Tariff Schedule of the United States (HTSUS), and it investigates whether imports cause material injury to U.S. industries in antidumping, countervailing duty, and safeguard proceedings.
In Detail
The USITC's tariff schedule function is administrative and continuous. It compiles and updates the HTSUS at least once a year—typically issuing a revised schedule effective January 1—incorporating WCO changes to the international Harmonized System, legislative amendments from Congress, new Chapter 99 provisions reflecting executive and trade remedy actions, and technical corrections. The official HTSUS, including an interactive search tool, is published on the USITC website and is the authoritative source for all import classification determinations.
Beyond schedule maintenance, the USITC conducts injury investigations when the Department of Commerce or domestic petitioners initiate antidumping or countervailing duty cases. The USITC determines whether a domestic industry is materially injured or threatened with injury by reason of the subject imports. A negative USITC determination terminates the proceeding; an affirmative determination leads to duty orders administered by Commerce and collected by CBP at the border.
The USITC also conducts Section 201 global safeguard investigations, Section 337 investigations of IP violations in imported goods, and publishes research on trade policy impacts. Its Dataweb portal provides public access to U.S. trade statistics organized by HTS code, making it a valuable resource for market analysis and classification research.
Classification Significance
The USITC's annual HTSUS update is the trigger event for corpus management in any classification program. When a new schedule takes effect, HTS codes, duty rates, and legal notes may change—and classifications made against an outdated schedule may be incorrect for goods entering after the update date. Tracking USITC publication dates and maintaining version-pinned corpus records is essential to classification accuracy and audit defensibility.
How Kanon Handles This
Kanon monitors USITC publications and ingests each new HTSUS version as a discrete, immutable corpus version the moment it takes effect. Prior classification records remain pinned to the corpus version under which they were made; new classifications are evaluated against the current version. The corpus version used for each determination is recorded in the Classification Support Package.
