IEEPA Refund vs. Duty Drawback vs. Section 301 Protest — The Complete Decision Tree for Importers

If you imported into the United States at any point from 2018 through 2026 and paid duties on that cargo, you probably qualify for at least one federal refund mechanism. Many importers qualify for three or four. The programs are not mutually exclusive — but the order in which you file them matters a great deal, because some programs reduce the base on which others are calculated.

This is a decision tree for importers of record, their CFOs, and their customs broker partners. For deeper analysis on any branch, the linked pages on Tariff Refund Credits go into per-program methodology.

The four primary recovery mechanisms

1. IEEPA refund via CAPE portal

• What it recovers: Duties paid 2018–2026 under IEEPA authority, struck down by SCOTUS 6–3 in Learning Resources v. Trump
• Filing window: 180 days from CAPE portal open
• Who files: Licensed customs broker on behalf of importer of record under 19 CFR 111
• Estimated pool: $166 billion, 330,000 importers
• Estimator: IEEPA refund calculator
• Deep dive: IEEPA eligibility guide

2. Section 301 protest (CF-19)

• What it recovers: Section 301 “China tariffs” duties on entries still within the 180-day protest window from liquidation
• Filing window: 180 days from entry liquidation (not from CAPE open)
• Who files: Importer directly, or broker on behalf
• Overlaps with CAPE: Yes — some Section 301 entries were re-issued under IEEPA authority in 2019 and qualify for CAPE and 301 protest
• Estimator: Section 301 protest calculator
• Deep dive: CF-19 protest guide

3. Section 232 refund

• What it recovers: Section 232 steel and aluminum tariff duties on HTS codes later granted exclusion
• Filing window: Variable, typically 180 days from exclusion grant publication
• Who files: Importer on CBP Form 19
• Overlaps with CAPE: Section 232 extensions issued under IEEPA authority (2024–2025) overlap. Earlier Section 232 does not.
• Estimator: Integrated into the tariff stacking calculator
• Deep dive: Section 232 refund guide

4. Duty drawback

• What it recovers: Up to 99% of duties on goods that were subsequently exported, destroyed, or used in the manufacture of an exported product
• Filing window: 5 years from import entry, much wider than any protest-based mechanism
• Who files: Licensed customs broker under 19 CFR 191
• Overlaps with CAPE: Significantly. The same entry can often be claimed under both — but the calculations interact.
• Estimator: Duty drawback calculator and 99% drawback calculator
• Deep dive: Duty drawback basics guide

The decision tree

Step 1 — Do you have entries 2018–2026?

If yes, you almost certainly have some IEEPA exposure. Start with the IEEPA calculator and the qualification quiz.

If no (you’re a 2027+ new importer), the rest of this decision tree doesn’t apply — you don’t have a historical refund claim.

Step 2 — Did you export or destroy any imported goods?

If yes, file duty drawback first. Drawback has a 5-year window — much longer than any of the protest-based mechanisms — but drawback calculations are based on the as-entered duty rate. If you file CAPE first and recover the IEEPA portion, the drawback base shrinks correspondingly. That’s fine and correct, but it means you want to model both before filing either.

The tariff stacking calculator models the interaction.

Step 3 — Are any of your 2024–2025 entries still in the 180-day liquidation window?

If yes, file CF-19 protest in parallel with CAPE. Section 301 protest is not subject to the CAPE window — it’s a separate statutory remedy — but it has its own 180-day-per-entry clock. Missing it because you were focused on CAPE is a common failure mode.

Step 4 — Do you have Section 232 exclusion grants?

If yes, file the 232 refund. This is usually a clean, non-interacting filing: the exclusion grant establishes the refund basis directly.

Step 5 — File CAPE

By the time you reach step 5, you’ve modeled drawback interaction, filed any CF-19 protests in flight, and filed any Section 232 refunds with exclusion grants. Now file CAPE.

The CAPE window calculator tells you how many days remain in the 180-day window.

The “all four” scenario

A sophisticated mid-market importer with exposure to all four programs typically recovers:

• 25–40% of total 2018–2026 duties via IEEPA/CAPE
• 5–15% additional via CF-19 protest on in-window entries
• 10–30% via drawback on re-exported goods
• Variable via Section 232 exclusion refunds

Total recovery in the highest-exposure scenarios approaches 60% of historical duty spend. This is what the calculators hub is designed to model.

What this platform does

Tariff Refund Credits is a lead-generation service that connects US importers with licensed customs broker partners. The platform itself:

• Runs the estimation calculators (free, no signup required)
• Matches qualifying importers with licensed broker partners who file under 19 CFR 111
