Bonded warehouses are one of the most useful tools in an importer’s toolkit — they let you defer duty payment until goods are actually withdrawn for domestic consumption. During the IEEPA tariff period, many importers used bonded warehouses strategically to defer the 20-34% IEEPA surcharges, hoping the tariffs would eventually be reduced or eliminated. Now that the Supreme Court has struck down IEEPA tariffs entirely, the question for bonded warehouse users is nuanced: which duties were actually paid, which were deferred, and what’s eligible for a refund?
The answer depends on timing — when goods entered the warehouse, when (or whether) they were withdrawn, and whether duties were assessed at entry or at withdrawal. This guide covers every bonded warehouse scenario and maps each to the appropriate IEEPA recovery path.
How Bonded Warehouses Work (Quick Review)
A bonded warehouse (also called a customs bonded warehouse or CBW) is a facility authorized by CBP where imported goods can be stored for up to five years without paying duties. Goods enter the warehouse under a “warehouse entry” (entry type 21 or 22) and duties are not assessed until the goods are “withdrawn for consumption” (entry type 38).
This is fundamentally different from how most imports work. In a standard import, duties are paid (or become payable) at the time of entry. In a bonded warehouse import, duties are deferred until withdrawal.
Key distinction for IEEPA purposes: If IEEPA duties were deferred (goods are still in the warehouse or were withdrawn after the ruling), you may not have paid IEEPA duties at all — meaning there’s nothing to refund. If IEEPA duties were paid (goods were withdrawn for consumption during the IEEPA period), you’re entitled to a refund under the same rules as any other importer.
Scenario 1: Goods Withdrawn During the IEEPA Period
If you withdrew goods from a bonded warehouse for domestic consumption between February 4, 2025, and February 24, 2026, the withdrawal entry was subject to IEEPA tariffs. The duty rate applied was the rate in effect at the time of withdrawal, not the rate at the time of original warehouse entry.
These duties are fully refundable. The withdrawal entry appears in your ES-003 report like any other entry with IEEPA tariff codes (9903.01 or 9903.02). The recovery paths are the same:
- Unliquidated withdrawal entries: File Post-Summary Corrections through your customs broker
- Liquidated withdrawal entries within the 180-day protest window: File protests under 19 U.S.C. Section 1514
- Liquidated entries outside the window: CIT litigation may be required
The procedural treatment is identical to direct-import entries. The bonded warehouse was simply the storage mechanism between arrival and consumption — once goods were withdrawn, they became subject to the same duties and the same refund eligibility as any other import.
Special Consideration: Partial Withdrawals
If you withdrew goods in batches over time (common in bonded warehouse operations), each withdrawal is a separate entry with its own duty assessment, liquidation status, and potential refund. Some withdrawals may have occurred before the IEEPA period (no IEEPA duty assessed, no refund needed), some during the period (IEEPA duty assessed, refundable), and some after the ruling (no IEEPA duty should have been assessed).
Your Impact Assessment should map each withdrawal entry individually rather than treating the warehouse lot as a single unit.
Scenario 2: Goods Still in the Bonded Warehouse
If you have goods that entered the bonded warehouse during or before the IEEPA period and are still in storage as of February 2026, you’re in an advantageous position: no IEEPA duties have been paid because no withdrawal has occurred.
When you eventually withdraw these goods for consumption, the applicable duty rate will be the rate in effect at withdrawal — which, post-ruling, does not include IEEPA tariffs. You should not be assessed any IEEPA surcharge on withdrawals made after February 24, 2026.
Action item: Coordinate with your customs broker to ensure withdrawal entries filed after the ruling date do not include IEEPA tariff lines. If your broker’s system automatically applies tariff rates based on product classification and origin, confirm that the IEEPA provisions have been removed from the rate database.
No refund to claim: Since duties were deferred and the tariff has been eliminated, there’s nothing to refund on these entries. The bonded warehouse deferral worked exactly as intended — you avoided paying a tariff that was later struck down.
The Five-Year Clock
Remember that bonded warehouse goods must be withdrawn within five years of the original warehouse entry date, or they become subject to duties and penalties. If you admitted goods in 2023 or 2024 specifically to defer IEEPA duties, ensure your withdrawal timeline still falls within the five-year window. Post-ruling, there’s less reason to delay withdrawal — the IEEPA tariff is gone.
Scenario 3: Goods Entered Warehouse Before IEEPA, Withdrawn During IEEPA
This is functionally the same as Scenario 1 — the duty is assessed at withdrawal, not at entry. If goods entered the warehouse in 2023 but were withdrawn in June 2025, the IEEPA rate applied at withdrawal is what you paid — and what’s refundable.
The timing of warehouse admission is irrelevant to the IEEPA refund calculation. What matters is:
- Was the withdrawal during the IEEPA period?
- Were IEEPA duties assessed?
- What’s the liquidation status of the withdrawal entry?
If the answers are yes, yes, and identifiable — you have a standard IEEPA refund claim.
Scenario 4: Goods Re-Exported or Destroyed in the Warehouse
Bonded warehouse goods can be re-exported or destroyed under CBP supervision without paying duties. If you re-exported IEEPA-affected goods from the warehouse (rather than withdrawing them for consumption), no IEEPA duties were paid — and there’s nothing to refund.
However, if the decision to re-export was driven by the IEEPA tariff making the goods uneconomical for the U.S. market, the elimination of the tariff may change your calculus. Goods still in the warehouse can now be withdrawn duty-free (at least with respect to the IEEPA surcharge), potentially making them viable for domestic sale after all.
Scenario 5: Manipulation in the Warehouse
Bonded warehouses allow certain types of manipulation — cleaning, sorting, repacking, relabeling — but not manufacturing. If you manipulated goods in the warehouse before withdrawal, the manipulation doesn’t change the duty treatment. The withdrawal entry is still assessed duties based on the goods’ classification and the rate at withdrawal.
IEEPA refund implication: Manipulation doesn’t affect refund eligibility. If IEEPA duties were assessed at withdrawal, they’re refundable regardless of any manipulation that occurred in the warehouse.
However, if manipulation changed the product’s tariff classification (which is technically manufacturing, not manipulation — a distinction that matters under warehouse regulations), the withdrawal entry may have been assessed duties under a different HTS heading than expected. Verify that the correct tariff lines were used.
Bonded Warehouse vs. FTZ: Key Differences for IEEPA
Importers sometimes confuse bonded warehouses with Foreign Trade Zones. They serve different purposes and have different IEEPA implications:
| Feature | Bonded Warehouse | Foreign Trade Zone |
|---|---|---|
| Duty assessment | At withdrawal for consumption | At withdrawal for consumption |
| Rate applied | Rate at withdrawal | Depends on PFS vs. NPFS election |
| Manufacturing allowed | No (manipulation only) | Yes |
| Status election | None (always assessed at withdrawal rate) | PFS locks in admission-date rate |
| IEEPA refund basis | Withdrawal entry duties | Withdrawal entry duties |
| Additional complexity | Straightforward | PFS/NPFS analysis required |
If you operate in an FTZ rather than a bonded warehouse (or in addition to a bonded warehouse), see the FTZ-specific IEEPA guide for the additional analysis you’ll need.
The Strategic Question: Was Bonded Warehousing Worth It?
For importers who used bonded warehouses during the IEEPA period specifically to defer tariff payment, the Supreme Court ruling validates that strategy — at least partially. If goods stayed in the warehouse through the ruling and are now being withdrawn post-IEEPA, you successfully avoided the tariff entirely. No duty paid, no refund needed, no queue to wait in.
But if you withdrew goods during the IEEPA period because business needs required it (inventory for holiday season, contractual delivery deadlines, etc.), you paid the same duties as everyone else — and your refund process is the same.
The importers who benefited most from the bonded warehouse strategy are those with:
- Low time sensitivity (goods that could sit in storage for months or years)
- Sufficient working capital to fund the storage costs
- Goods with long shelf lives (industrial components, raw materials, durable goods)
The importers who didn’t benefit are those who had to withdraw goods within the IEEPA period regardless of the tariff. For them, the bonded warehouse deferred the payment by weeks or months but didn’t ultimately avoid it.
Calculating Your Bonded Warehouse IEEPA Exposure
If you used a bonded warehouse during the IEEPA period, your total IEEPA exposure includes:
| Category | IEEPA Exposure | Action Needed |
|---|---|---|
| Goods withdrawn during IEEPA period | Full IEEPA duties paid | File for refund |
| Goods still in warehouse | No IEEPA duties paid | Ensure correct withdrawal rate post-ruling |
| Goods re-exported from warehouse | No IEEPA duties paid | No action needed |
| Goods destroyed in warehouse | No IEEPA duties paid | No action needed |
Your ES-003 report will show the withdrawal entries where IEEPA duties were actually assessed and paid. Only these entries are eligible for refunds.
Important: The ES-003 report covers entries filed under your IOR number. If the bonded warehouse operator filed entries under their IOR (which is uncommon but possible), you’ll need to coordinate with the operator to access the data.
Documentation for Bonded Warehouse Claims
In addition to the standard IEEPA recovery documentation, bonded warehouse users may need:
- Warehouse entry documentation (entry type 21/22): Proves goods entered the warehouse under bond
- Withdrawal entry documentation (entry type 38): Shows the actual duties paid at withdrawal — this is the basis for your refund claim
- Warehouse inventory records: Reconcile what was admitted, what was withdrawn, and what remains
- Manipulation records (if applicable): Document any changes to goods while in the warehouse
- Storage invoices: Not strictly required for the refund claim, but useful for establishing the timeline
Your customs broker and warehouse operator should have all of these records. Request them now if you haven’t already — some operators charge fees for historical record retrieval, and the process can take 1-2 weeks.
The Interaction With Duty Drawback
Some importers use bonded warehouses in conjunction with duty drawback programs. If you import goods, store them in a bonded warehouse, and then re-export them (or incorporate them into manufactured goods that are exported), you may be eligible for both a drawback claim and an IEEPA refund claim — but not on the same duties.
The general rule: you can’t recover the same duties twice. If you’re pursuing drawback on goods that were also subject to IEEPA tariffs, coordinate both claims carefully to avoid double-dipping. Your broker or trade attorney should review the overlap.
Case Scenario: A Bonded Warehouse Strategy That Worked
Let’s look at how one importer — we’ll call them Continental Metals — used a bonded warehouse during the IEEPA period and how the recovery plays out.
Continental Metals imports specialty steel alloys from mills in China for sale to U.S. manufacturers. Their annual import volume runs about $8 million in customs value. When IEEPA tariffs took effect in February 2025, Continental immediately shifted to a bonded warehouse strategy: all incoming shipments were admitted to a bonded warehouse rather than cleared for consumption.
Over the 12-month IEEPA period, Continental admitted approximately $7.5 million in steel to the warehouse. They withdrew goods in batches as customer orders came in — approximately $5.2 million in goods were withdrawn for consumption during the IEEPA period, with $2.3 million remaining in the warehouse as of the ruling date.
IEEPA exposure on withdrawals: $5.2 million in goods at a 24% blended IEEPA rate = $1,248,000 in IEEPA duties paid at withdrawal.
Goods still in warehouse: $2.3 million in goods with zero IEEPA duties paid (duties deferred). Post-ruling, these goods can be withdrawn without IEEPA surcharge.
IEEPA duties saved by the warehouse strategy: If Continental had cleared all $7.5 million directly (without the warehouse), they would have paid approximately $1,800,000 in IEEPA duties. By using the warehouse, they paid $1,248,000 — saving $552,000 in duties that were deferred and are now permanently avoided.
Recovery on duties actually paid: Continental is filing for full recovery of the $1,248,000 through the standard recovery paths — PSCs for unliquidated withdrawal entries and protests for liquidated ones.
Net financial outcome: Continental will recover the $1,248,000 it paid, and the $552,000 it deferred was never paid. Total IEEPA cost after recovery: effectively zero (minus some warehouse storage costs of approximately $40,000).
The bonded warehouse strategy worked for Continental because their goods — steel alloys — have an indefinite shelf life and their customers could tolerate some delivery variability. For perishable goods or time-sensitive products, the strategy would have been less effective because goods would need to be withdrawn regardless of the tariff environment.
Practical Steps for Bonded Warehouse Users
1. Identify all withdrawal entries during the IEEPA period. Pull your ES-003 data and filter for entry type 38 with IEEPA tariff codes.
2. Confirm the duty amounts. Bonded warehouse withdrawals can be complex, especially with partial withdrawals over time. Verify the IEEPA duty on each withdrawal entry.
3. Check liquidation status. Withdrawal entries follow the same liquidation timeline as other entries (~314 days). Map each entry to a recovery path based on its status.
4. File deadline-sensitive entries first. The earliest withdrawals (February-March 2025) may have liquidated and their protest windows may be approaching closure.
5. Confirm post-ruling withdrawal treatment. For goods still in the warehouse, verify with your broker that future withdrawals won’t be assessed IEEPA duties.
6. Get your Impact Assessment. The assessment will quantify your total refund, identify deadline risks, and map the optimal recovery strategy.
