Substitution drawback on reciprocal tariffs can create meaningful recovery opportunities, particularly when duty rates changed during the program. However, selecting a higher-duty import is not an unrestricted election. HTSUS eligibility, valuation limits, available import inventory, and duplicate-refund controls all affect the amount that can ultimately be claimed.
Reciprocal Tariffs and the Current Drawback Landscape
CBP permitted qualifying reciprocal duties imposed under the International Emergency Economic Powers Act to be included in duty drawback claims. This treatment extended to unused merchandise substitution drawback under 19 U.S.C. 1313(j)(2), allowing an eligible export to be matched with qualifying imported merchandise even when the exported article was not the exact imported unit.
That historical eligibility remains relevant despite the termination of reciprocal tariffs following the Supreme Court's February 20, 2026 decision. CBP subsequently moved toward CAPE refund processing in ACE for duties paid under the discontinued tariff program. As a result, importers, brokers, and drawback specialists must now evaluate two potential recovery channels involving the same duties.
Historical Eligibility Does Not Permit Double Recovery
A qualifying past entry may still support a drawback claim if the underlying reciprocal duty has not already been refunded through CAPE or another mechanism. The same duty payment generally cannot be recovered twice. If CBP refunds a tariff through entry-level processing, that refunded amount is no longer available as the basis for drawback.
This makes line-level reconciliation essential. A defensible process should identify the original entry, tariff amount paid, current liquidation or refund status, drawback designation status, and any CAPE refund associated with that entry line. Pending claims may also require adjustment if the underlying duty is refunded after the drawback work has begun.
The strategic question is therefore no longer simply whether reciprocal tariffs were drawback eligible. It is whether a specific duty payment remains legally and operationally available for recovery. Brokers should verify that the designated import duty still exists, has not been refunded, and satisfies all applicable drawback conditions before including it in a claim.
Can a Claim Use the Higher Historical Duty Rate?
Unused substitution drawback generally allows a claimant to prioritize qualifying imports that produced the greatest recoverable duty. If an importer paid a 20% reciprocal tariff on one group of EU goods and later paid 15% on another group, an eligible export may potentially be designated against the 20% imports rather than the 15% imports.
That does not mean the claimant may simply elect a 20% rate in the abstract. The claim must designate an actual import entry on which the 20% duty was paid. The designated merchandise must remain available within the claimant's drawback inventory, satisfy the applicable timing requirements, and qualify for substitution with the exported or destroyed merchandise.
Import Designation Is Strategic, Not Arbitrary
Substitution is valuable because it separates the export from the physical imported unit. It does not separate the claim from the underlying import record. The claimant must maintain evidence connecting the drawback calculation to a real entry, an eligible tariff classification, the duty paid, and the relevant quantity and value.
A claimant can generally develop a designation methodology that prioritizes high-duty imports. For example, an inventory containing otherwise eligible imports assessed at 10%, 15%, and 20% may be configured to use the 20% duty layer first. This approach reflects the economic purpose of substitution drawback, but it remains subject to statutory caps and classification rules.
The export also does not automatically generate a refund based on the designated import's full duty rate. Under the lesser-of-two limitation, drawback is generally capped by the lower of the eligible duties paid on the designated imports or the duties that would apply to the substituted exported merchandise if imported. Value differences can therefore reduce the recovery. The statutory maximum is typically 99% of the qualifying duty amount after applicable limitations are considered.
HTSUS Matching, the Other-Other Rule, and Duty Caps
Classification is central to unused merchandise substitution drawback. The imported and substituted merchandise generally must fall within the same 8-digit HTSUS subheading. A commercial description that appears similar is not enough if the tariff classifications do not satisfy the substitution standard.
The classification should be validated independently for both sides of the transaction. Import records establish the designated merchandise and duties paid, while export records establish the substituted merchandise, quantity, value, export date, and classification. Inconsistent classifications, unsupported post-entry changes, or descriptions that do not align with the HTSUS can undermine the claim.
The Other-Other Limitation
A significant restriction applies when the 8-digit HTSUS description begins with the word “other.” In that situation, substitution is generally barred unless the imported and exported merchandise share the same 10-digit statistical reporting number and the description at that level does not also begin with “other.” This is commonly called the Other-Other rule.
The restriction prevents broad residual tariff categories from being used to substitute materially different goods. It should be evaluated before allocating imports to exports because a seemingly valid 8-digit match may still be ineligible. Claim systems and review procedures should therefore examine both the 8-digit subheading and the complete 10-digit classification.
Applying the Lesser-of-Two Limitation
Even when the classification match is valid, the refund calculation must address the relative duty exposure of the imported and exported merchandise. The recoverable amount is generally limited to the lesser of the qualifying duty paid on the designated imports or the duty that would apply to the substituted merchandise. The export value per unit and import value per unit can materially affect this calculation.
For example, designating a 20% import does not necessarily produce a refund equal to 99% of that entire duty payment if the substituted export has a lower value or lower hypothetical duty exposure. Quantity conversions, unit-of-measure consistency, entered value, export value, and tariff treatment should all be reviewed before the expected recovery is recorded.
- CBP confirmed drawback eligibility for IEEPA reciprocal tariffs (including unused substitution under 19 U.S.C. 1313(j)(2)) in April 2025 CSMS guidance, allowing claims against higher-duty imports if HTSUS 8-digit (or 10-digit under the Other-Other rule) classifications match; the lesser-of-two cap applies (99% of duties paid on designated imports or duties that would apply if the substituted/exported goods were imported).*
- Reciprocal/IEEPA tariffs ended after the Supreme Court ruling on February 20, 2026 (Learning Resources v. Trump); CBP shifted to CAPE refunds in ACE for paid duties, with drawback still available for qualifying past entries but no double recovery allowed. No new CBP CSMS or regulatory updates on substitution for these in the past 30 days.
- October 27, 2026 BDO insight recapped the January 30, 2024 CIT decision (Spirit AeroSystems v. United States) upholding CBP's strict application of the Other-Other rule under 1313(j)(5): substitution unused drawback is barred if the 8-digit HTSUS description starts with "other" unless the same 10-digit SRN applies and its description does not start with "other." This limitation remains relevant for any substitution claims on remaining eligible duties.
- October 22, 2026 CustomsGenius overview restated that substitution (manufacturing or unused) requires the same 8-digit HTSUS subheading, commercially interchangeable goods, and the lesser-of-two refund cap to prevent claiming higher-duty imports against lower-duty exports; this applies to Section 301 and similar remaining programs.
- October 30, 2026 industry coverage highlighted substitution drawback's value for matching exports (any origin) to high-duty imports like Section 301 China tariffs at the 8-digit HTS level, similar to the practitioner approach described for reciprocal duties. No recent X discussions specifically addressed electing higher historical rates (e.g., EU 20% vs. later 15%) for substitution claims.
Frequently Asked Questions
Can reciprocal tariffs still be included in drawback claims?
Qualifying historical reciprocal duties may still support drawback when the statutory requirements are met and the duties have not been returned through CAPE or another refund process. Because the reciprocal tariff program ended in 2026, current analysis should focus on historical entries, remaining filing periods, claim status, and whether the original duty payment remains unrecovered.
Can a claimant always select imports assessed at 20% instead of 15%?
No. A claimant may generally prioritize actual higher-duty imports that qualify for substitution, but it cannot create or arbitrarily elect a historical rate. The 20% duty must have been paid on a designated entry, the merchandise must be eligible, and the import must remain available for drawback. The lesser-of-two limitation can also reduce the resulting refund.
Must the imported and exported goods have the same country of origin?
Country of origin is not generally the controlling substitution test under unused merchandise drawback. The more important considerations typically include HTSUS eligibility, applicable timing requirements, quantity, value, unused status, and supporting records. Separate tariff measures tied to origin may still affect the hypothetical duty calculation and should be reviewed carefully.
What happens if the 8-digit HTSUS description begins with “other”?
The Other-Other rule generally requires the imported and exported merchandise to share the same 10-digit statistical reporting number. In addition, the 10-digit description must not begin with “other.” If both the applicable 8-digit and 10-digit descriptions begin with that term, unused substitution drawback is generally unavailable for that pairing.
How should CAPE refunds be coordinated with drawback?
Importers and brokers should reconcile CAPE activity against drawback-designated entries at the entry-line level. Duties already refunded should be removed from the drawback basis. If a CAPE refund occurs after a claim is prepared or filed, the claimant may need to update records, amend the claim, or otherwise address the duplicate recovery risk with CBP.
How Stable Software Can Help
Build a More Controlled Drawback Process
Managing substitution drawback requires consistent import-to-export matching, careful duty calculations, and visibility into which entries remain available for designation. These controls become especially important when historical rates vary or separate refund processes may affect the same duties.
DrawbackAI is flat-license duty drawback software that U.S. customs brokers can white-label for importer clients and use to file under their own filer codes. Stable Software charges a flat software license and never takes a percentage of the refund. Brokers evaluating historical reciprocal tariff claims can use a structured software process to support scalable drawback operations while retaining control of client service, filing decisions, and refund economics.
