Navigating The US Tariff Refunds

The filing is the easy part.

U.S. Customs opened the refund window on April 20. An estimated $175 billion in duties, collected from more than 300,000 importers under the International Emergency Economic Powers Act (IEEPA) authorities, is now, in principle, recoverable. Importers who were already registered for ACH payments can submit claims through familiar channels, and CBP has built the process to absorb the volume.

So getting the money you spent on tariffs back should be straightforward, right?

Not even close.

For any manufacturer, distributor, or retailer whose product moved through more than one set of hands before reaching an end user, the refund is not a payment. It is a negotiation. And the negotiation starts with a question most companies cannot cleanly answer: who actually bore the cost of each tariff dollar, SKU by SKU, component by component, customer by customer.

How We Got Here: The 60-Second Version

Quick level-set, because the history drives the refund math.

In February 2025, the administration invoked IEEPA to impose trafficking-related tariffs on imports from Canada, Mexico, and China. On April 2, 2025, a separate IEEPA action introduced the Liberation Day reciprocal tariffs: 10% on nearly all trading partners, with higher rates for designated jurisdictions. These sat on top of pre-existing Section 232 and Section 301 duties, which rest on different statutory authority and remain in force.

The challenge came fast. Small businesses and state governments argued that the 1977 statute, contains no tariff authority at all. The Court of International Trade agreed in May 2025. On February 20, 2026, the Supreme Court ruled 6-3 in that IEEPA does not authorize the President to impose tariffs.

Where the Mess Lives: Manufacturing, Distribution, Retail

Tariffs hit the import line once. The cost hits the rest of the chain repeatedly, and the refund process has to work that chain in reverse.

Manufacturers. If you imported raw materials or components under IEEPA, you paid the duty, booked it into inventory standard cost, and almost certainly adjusted prices. Either through explicit tariff surcharges on invoices or through a general cost pass-through baked into next quarter’s price sheet. Your refund claim runs against your original entry summary. That part is clean. The hard part is what you do with the money once it arrives. Your customers know the ruling happened. They are already asking.

Distributors. You likely did not import, but you paid your supplier’s tariff-inclusive price. You then passed some or all of that cost to your own customers, usually with a margin layer on top. You have no standing to file with CBP directly. Your only recovery path runs through your upstream supplier, and that path is governed by whatever contract language you had. Or didn’t have.

Retailers. Same position as distributors, magnified. Retail customers are the loudest and the least likely to have contractual tariff adjustment clauses. NPR has already reported lawsuits from end customers seeking their share of refunds on goods purchased during the tariff window.

The common thread: every party in the chain has an intuition that they paid for the tariff and should get some refund back. Most of them are partially right. Few of them have the records to prove exactly how right.

The Component-Level Problem

This is the operational scenario that is going to consume the next 18 months of finance and supply chain leadership attention.

Consider a Tier 1 U.S. manufacturer importing a finished subassembly from a contract manufacturer in Vietnam. The Vietnamese supplier, in turn, sourced three critical components: one from China (subject to both IEEPA reciprocal and Section 301 duties), one from Mexico (IEEPA trafficking), and one from within Vietnam (IEEPA reciprocal). The subassembly enters the U.S. under a single HTS code. The tariff applied at the border is a blended rate reflecting the country of origin of the finished subassembly, not the underlying components.

The IEEPA portion of that duty is now refundable. The Section 301 portion is not, and your refund filing needs to separate the two. Your ERP probably didn’t.

Most landed cost models treat duty as a single bucket, applied at entry, rolled into standard cost. Few companies maintained a parallel ledger tracking which statutory authority underlies each dollar of duty paid.

Now add the downstream layer. That subassembly went into five finished SKUs you sell to 47 distributors, who in turn sold it into roughly 12,000 end customer accounts. A large distributor sends you a letter citing the $2.3 million in tariff-inclusive purchases they made from you between March 2025 and February 2026, asking for their proportional refund.

Almost no company has all of this broken out so cleanly. The ones that do are the ones that treated tariff exposure as a planning variable rather than an accounting afterthought. They tagged tariff cost by statutory authority, by SKU, by entry, and maintained the audit trail. That group is small.

At GAINS we spend most of our client work on cost-to-serve, landed-cost visibility, and scenario modeling, and even among the best-instrumented supply chain organizations we partner with, IEEPA-specific tagging was inconsistent through 2025. Almost nobody knew in February 2025 that the specific statutory authority behind each tariff line would matter this much, 14 months later. Companies that carried multi-tier visibility into the period are reconstructing the refund picture in days. Companies that didn’t are looking at months of forensic accounting.

The other dimension worth naming: this is not a one-pass exercise. Your customers will file claims against you. You will file claims against your suppliers. Your suppliers will file claims against their customs brokers and their own upstream sources. Each link in that chain is running its own allocation math, on different timelines, with different documentation standards. The first refund dollar from CBP triggers a cascade of downstream settlements that can easily take 18 months to resolve.

What to Do Right Now

Three priorities deserve immediate attention from finance and supply chain leadership. None of them is “file the refund claim.”

First, reconstruct the data. Pull entry summaries for every IEEPA-affected import between February 4, 2025, and February 24, 2026. Separate IEEPA duty from Section 232 and Section 301 duty at the line level. If that breakdown isn’t clean in your ERP, your customs broker has it. Request it now, before the volume of broker requests makes response times unworkable.

Second, model the pass-through. Build a defensible allocation of how IEEPA duty flowed into SKU standard cost and into customer pricing. If you ran explicit tariff surcharges, the math is easier. If you blended recovery into general price increases, you need a documented methodology, because you are going to be defending it to customers and possibly to counsel.

Third, get ahead of the customer conversation. The distributors calling you in May will ask for lump-sum refunds. The ones calling in July will have built their own spreadsheets. The ones calling in September will have attorneys. Your posture in May sets the expectation for the whole cycle.

More than anything else: keep your receipts. Every entry, every invoice, every internal cost allocation memo, every customer pricing notice issued during the tariff window. The refund period will be audited, litigated, and negotiated for years. The companies that come out clean are the ones that already have the documentation. The companies that come out bruised are the ones reconstructing it under pressure.

The Bottom Line

The Supreme Court resolved a constitutional question in February. It did not resolve the operational one. For every importer who paid, every distributor who marked up, every retailer who sold through, and every end customer who bought at the tariff-inflated price, the next year is going to be a structured argument about who gets what share of $175 billion.

Tariffs were political theater for most of 2025. Refunds will be financial theater for most of 2026. The companies that treat this as a data problem, not a compliance event, will come out ahead.
