Customs Protest Deadline: 180 Days From Liquidation Explained

Key Points

• The customs protest deadline is 180 days, counted from the date the liquidation notice is posted, not from the entry date or the date you paid duties.
• For a CBP decision that does not involve a liquidation, the 180 days run from the date of the decision.
• A protest may be amended until the 180 days run, so a timely, narrow protest can be improved but a late one cannot be rescued.
• A request for accelerated disposition may be filed with the protest or at any time after it, and a protest not allowed or denied within 30 days of the request is deemed denied on the thirtieth day.

The deadline to file a customs protest is 180 days. Under 19 U.S.C. 1514(c)(3), the period runs from the date of liquidation or reliquidation, and the date of liquidation is the date the notice of liquidation is posted. It does not run from the entry date, the date of release, or the date you paid duties.

What starts the 180-day clock

The posting of the liquidation notice

Under 19 CFR 159.9, the date of liquidation is the date the bulletin notice of liquidation is posted. That bulletin notice is now the notice posted in ACE. The practical consequence: the posting date, not the date someone at your company noticed it, controls.

Reliquidation

The statute counts 180 days from liquidation or reliquidation. If CBP reliquidates an entry, the reliquidation date is the relevant date for the 180 days, as the statute is written. Confirm which date applies to the specific issue you are protesting before you rely on a later date.

Dates that do not start the clock

• The date of entry or entry summary filing.
• The date of duty payment.
• The date you discovered the error or received a refund denial from another process.

What the deadline covers

Most protests challenge a liquidation, such as classification, valuation, or a duty assessment. But the statute also covers decisions that do not involve a liquidation. For those, 19 U.S.C. 1514(c)(3) counts 180 days from the date of the decision.

For the underlying right to protest and the kinds of decisions that can be challenged, see CBP protest under 19 U.S.C. 1514: challenging liquidation decisions.

Filing mechanics that affect timing

Form and channel

19 CFR 174.12 provides for filing on CBP Form 19 or in ACE. Our guide to CBP Form 19 protests covers the form itself. Build in time before the 180th day for technical problems, not just for drafting.

One protest, several entries

Under 19 CFR 174.13, one protest may cover several entries when they are at the same port, involve the same category of merchandise, and raise the same issue. Each entry still has its own liquidation date, so each entry has its own 180-day deadline. When entries liquidated on different days, the earliest posting date sets the first deadline you must meet.

Amending a protest

19 CFR 174.14 allows a protest to be amended until the 180 days run. That is a reason to file early with the core grounds stated, then add detail or supporting argument while time remains. It is not a reason to file a placeholder and assume you can fix everything on day 179.

The accelerated disposition request

Once a protest is on file, CBP is not obligated to decide it quickly. The agency's target is two years, per 19 CFR 174.21. Accelerated disposition is the tool for forcing a faster answer.

When you can file it

Under 19 U.S.C. 1515(b) as amended, a request for accelerated disposition may be filed concurrently with the protest or at any time after it. The text of 19 CFR 174.22 still describes a 90-day wait. Where the two differ, the statute controls.

What happens after the request

• CBP has 30 days from the request to allow or deny the protest.
• If the protest is not allowed or denied within 30 days of the request, it is deemed denied on the thirtieth day.
• A deemed denial is a denial, which matters for what you can do next.

When it makes sense

Accelerated disposition suits a protest where the issue is a pure legal question and you expect to litigate regardless, or where a long CBP review would only delay the inevitable. It is a poor fit when you want CBP to take time to consider new evidence, since a deemed denial can arrive without any substantive review. If the protest is denied, the next stage is court review, covered in Protest denied: the road to the Court of International Trade.

What importers should do

• Record the posted liquidation date for every entry at issue, and calendar the 180th day from that date, with an internal deadline well before it.
• File a protest that states the issue clearly, using one protest only where the entries meet the same-port, same-merchandise, same-issue test, and amend before the 180 days run if you need to add grounds.
• Decide at filing whether to request accelerated disposition, and if so, whether to file it concurrently or later, keeping the 30-day deemed denial in mind.
• Monitor ACE for liquidation postings on a routine schedule so the clock is never discovered after the fact.
