Recent tariff policies have significantly impacted project costs for U.S. construction contractors. Import duties on steel, aluminum, equipment, and materials were often included in bids before projects started. A Supreme Court ruling now allows for refunds of billions in tariffs collected under emergency powers. To secure these funds, contractors must act quickly and coordinate documentation across finance, tax, and procurement teams.
In February, the U.S. Supreme Court ruled in Learning Resources v. Trump that the International Emergency Economic Powers Act (IEEPA) does not authorize the president to impose broad‑based tariffs without explicit congressional approval. The decision invalidated a significant set of duties imposed in recent years. While the Court did not address refunds directly, the U.S. Court of International Trade later ordered U.S. Customs and Border Protection (CBP) to unwind qualifying tariffs for eligible import entries.
CBP has started processing these refunds.
What the Refund Process Means for Construction
On April 20, CBP launched the first phase of an automated refund process within its Automated Commercial Environment. The Consolidated Administration and Processing of Entries (CAPE) system recalculates duties as if IEEPA tariffs were never assessed and returns both duties and interest to eligible importers of record.
For many construction companies, the opportunity is indirect. Contractors were often not the importer of record; suppliers, distributors, or manufacturers paid the duties and passed the costs through contract pricing. In these cases, the legal right to a refund belongs to upstream parties, even though contractors bore the cost in project budgets.
This structure raises two key questions for contractors: who is eligible to file the refund claim, and whether contract terms allow recovery of previously passed-through tariff costs.
Cash Flow Relief and Compliance Exposure
For firms that were importers of record, refunds can provide significant cash flow relief as margins remain tight and financing costs high. CBP expects to process accepted claims within 60 to 90 days, though early users have reported technical delays as the system scales.
Filing a claim also reopens historical import entries, allowing CBP to review valuation, tariff classification, and country of origin determinations. Construction companies importing specialized equipment or components may face additional scrutiny if inconsistencies exist across projects or suppliers.
Refund claims should therefore be treated as compliance events. Accurate data, thorough documentation, and coordination among customs, tax, and accounting teams are essential.
Supplier and Contract Considerations
Even if contractors cannot file claims directly, refunds may impact commercial relationships. If a supplier recovers tariffs previously included in pricing, customers may have grounds to seek credits or adjustments, especially in long-term, cost-plus, or open-book contracts.
Outcomes will vary. Some suppliers may resist revisiting settled transactions, while others may be willing to negotiate as part of broader relationship management. Contractors who can link tariff costs to specific invoices, purchase orders, or schedules of values will be better positioned in these discussions.
State Sales Tax Implications
Refunded tariffs can also create state and local tax issues. In many states, sales and use tax is based on the total purchase price, including tariffs. Retroactive tariff refunds may mean the taxable base was overstated, creating potential sales tax refund opportunities.
State rules vary on who can file a claim and how refunds are handled. In some jurisdictions, only the tax remitter may request a refund; in others, refunds must be passed to the end customer. Contractors and suppliers should anticipate additional documentation and longer timelines as states issue guidance.
A Coordinated Financial Exercise
For construction executives, the IEEPA tariff refund process requires coordination across customs, tax, accounting, and contract functions. While speed is important, accuracy and consistency are critical.
Phase 1 of the CAPE system covers only unliquidated entries and those liquidated within a limited window. Additional phases are expected, but timelines remain uncertain as CBP manages high claim volumes.
Although the tariffs no longer apply, their financial impact remains in project costs and supplier pricing. Contractors who act early and methodically may recover funds to offset years of higher material costs. Others risk missing the opportunity with little notice or recourse.
