The 180-Day Clock Is Running: Why Your IEEPA Protest Rights May Expire Before CAPE Processes Your Refund

The Deadline Nobody Is Talking About

The IEEPA refund conversation has been dominated by the CAPE portal: how to file, what to include, when to expect payment. What is not being discussed nearly enough is the 180-day protest clock — a hard statutory deadline that can permanently extinguish your right to recover duties if it expires before you act.

Under 19 U.S.C. § 1514, an importer has 180 days from the date of entry liquidation to file a protest contesting a CBP decision. After that window closes, the liquidation is final. It cannot be reopened. It cannot be challenged administratively. The only remaining avenue is federal court — an expensive and slow option that few importers will pursue.

How the Math Works Against You

IEEPA tariffs were imposed beginning in early 2025. Entries that shipped and liquidated in mid-2025 — roughly March through June 2025 — had 180-day protest windows that began closing in September 2025. Those windows are now long gone.

Entries that liquidated in late 2025 — say, November or December — have protest windows closing around May and June 2026. Right now. While the CAPE portal is still processing.

CBP has indicated that CAPE processing takes 60–90 days. An importer who submitted a CAPE Declaration in late April 2026 for a December 2025 liquidated entry may receive the CBP decision in late June or July — after the protest window for that entry has already closed.

CAPE Does Not Toll the Protest Deadline

This is the critical point. CBP has not published any guidance stating that a CAPE Declaration filing pauses, tolls, or extends the 180-day protest deadline. Reuters, in its April 22, 2026 analysis, stated explicitly that "importers should prioritize preparation for both CAPE declarations and protest submissions" — acknowledging that both must be filed independently.

This is not a technicality. It is the difference between having administrative remedies available if CBP denies your CAPE claim and having none.

The Dual-Track Protocol

The appropriate strategy, endorsed by trade counsel across the bar, is a dual-track filing approach:

1. Submit your CAPE Declaration for all eligible liquidated entries as promptly as possible.
2. File a protective protest under 19 U.S.C. § 1514 for every entry where the 180-day window is still open — regardless of CAPE status. A protective protest is an affirmative statement that you dispute the duty assessment and wish to preserve your rights.

The protective protest costs almost nothing additional to file alongside a CAPE Declaration. It is the insurance policy that ensures a CAPE denial does not end your recovery options.

Identifying Your Open Windows Now

To determine which entries still have open protest windows, you need the liquidation date for every IEEPA-affected entry. In ACE, your entry summary report will include this date. From there:

• Entries liquidated before October 24, 2025: protest window almost certainly closed
• Entries liquidated October 24, 2025 – April 20, 2026: protest window open now, closing imminently
• Entries liquidated after April 20, 2026: 180-day window still well open

For the middle category — entries in that October-through-April band — speed matters. Every day without a filed protest is a day closer to permanent foreclosure of your administrative rights.

What We Do in the Forensic Review

Our forensic review, which is free, maps every affected entry to its liquidation date and calculates the exact protest deadline for each. It identifies which entries are in the critical window, prepares the protective protest filings in parallel with the CAPE Declaration, and ensures your recovery options across both tracks remain fully intact when CBP issues its determinations.
