CBP Form 29
What is CBP Form 29?
CBP Form 29 is the Notice of Action. It tells the importer that CBP proposes a change to the entry, or has made one.
CBP uses Form 29 when the entered rate or value is too low, or the quantity is more than entered. The added duty must be over $15 (19 CFR 152.2).
A CF-29 often follows a CF-28. It can also come on its own.
Who and when
Who needs it and when?
- CBP sends it to the importer of record or its broker.
- Read whether the action is proposed or taken. A proposed action is your chance to respond before CBP liquidates.
- CBP liquidates promptly. 19 CFR 152.2 lets CBP withhold liquidation no more than 20 days from the mailing of the notice, unless there are compelling reasons.
Roles
Who signs it and who files it?
- CBP issues and signs the notice. You do not file a CF-29.
- You, or your broker, answer a proposed action in writing, with facts and documents.
- If CBP liquidates with the change, contest it with a protest within 180 days of liquidation (19 CFR 174.12). See CBP Form 19.
