CBP Form 29 (CF29) is a Notice of Action proposing changes to entry treatment – rate increase, classification change, valuation adjustment. Importer has limited window (typically 20 days) to respond before action becomes final. Failure to respond results in liquidation at the proposed rate; protest rights remain.
This guide covers CBP Form 29 Response Guide. Customs compliance audit work covers CBP focused assessments, CBSA Trade Compliance Verifications, and ongoing compliance program work.
For SMB importers, the practical implementation depends on volume, sector, and operational structure.
