Section 337 review ties USITC investigations, limited and general exclusion orders, and CBP enforcement to the products and HTS lines an importer brings in.
This page is the public entry point. It explains the issue, links to the public tools that surface the primary records, and routes repeat work into review.
Use this when the first question is which investigation created the signal.
Use this to match covered articles against your products and components.
Use this when admissibility depends on CBP instructions or an order in force.
A Section 337 exclusion order can bar covered goods at entry, so the operational risk is the shipment being stopped, not a higher duty. Importers need to know when an order reaches a product they bring in.
Traverse keeps each Section 337 investigation and order tied to the covered articles, respondents, and primary record, so admissibility risk stays connected to the source.
Track USITC institution notices, complaints, limited and general exclusion orders, cease-and-desist orders, and CBP enforcement instructions that can stop covered goods at the border.
Section 337 is an exclusion remedy, not a duty rate. A general or limited exclusion order can bar entry of covered articles entirely, so the question is admissibility, not the rate owed.
Review it when an investigation or order covers a product family, component, or supplier you keep importing, so a new order or modification is caught before entry.
