U.S. production volumes are classified as confidential business information.
US ProductionCBI
Confidential Business Information. The EPA withholds this volume because publishing it could reveal the reporting company's trade secrets.
The EPA did not publish how much of this chemical companies made or imported, or marked that amount confidential. Without that volume, ACID cannot calculate import dependency.
