U.S. Customs and Border Protection will open a third phase of its IEEPA tariff-refund process on Oct. 6, extending refund eligibility to roughly $11.4 billion in older entries whose customs assessment has already closed, according to a CBP court filing reported by Supply Chain Dive. That figure covers about 6.9% of the tariffs collected under the International Emergency Economic Powers Act, tariffs a Supreme Court ruling struck down earlier this year. The expansion adds to a refund pipeline already worth well over $100 billion, money that flows to the businesses that paid the tariffs rather than directly to shoppers.
Oct. 6 refund expansion: The $11.4 billion moving through customs goes to importers, not household budgets already covering a property-tax bill or a utility account. The Senior Property Tax & Home-Cost Relief Kit sorts through relief options for both. Scan the five kinds of property-tax relief →
What Changes On Oct. 6
CBP’s court filing, reported Sept. 17, describes a third phase of its Collections and Payment Enforcement refund process opening Oct. 6 for “finally liquidated” entries, the older shipments whose customs assessment has already been closed out rather than left open for later adjustment. That phase alone covers about $11.4 billion, or roughly 6.9% of the tariffs collected under IEEPA, on top of $134.7 billion in refunds the agency had already deemed potential or certified as of Sept. 11. A customs-broker client advisory covering the same filing put the total already transmitted, including interest, at roughly $122 billion across more than 286,000 refund declarations, of which upward of 201,000 have been accepted so far.
Why These Tariffs Are Being Refunded At All
The refunds exist because the tariffs themselves did not survive a legal challenge. The Supreme Court ruled in Learning Resources, Inc. v. Trump on Feb. 20, 2026, that the president lacked authority under IEEPA to impose the tariffs in the first place, a decision the Congressional Budget Office cites directly in its own federal budget accounting. CBP began issuing refunds in May, and by the end of August had returned about $110 billion to importers, the CBO’s Sept. 9 Monthly Budget Review shows. The same document found August’s customs-duty collections fell 59%, or $17 billion, from a year earlier as a direct result of the refund program, even though customs collections for the 11 months through August were still running about 1% ahead of the prior year overall, a reminder that a single month’s refund-driven dip does not erase the broader run of tariff revenue collected earlier in the fiscal year before the ruling took hold.
How Large The Refund Pipeline Has Grown
Between the roughly $110 billion CBO tracked through August and the $134.7 billion CBP now calls potential or certified, the refund program has expanded steadily since the Supreme Court’s ruling closed off the tariffs it covers. The customs-broker advisory puts the underlying entry count at about 27.2 million, with roughly $1.3 billion still on hold across some 20,184 cases awaiting electronic payment, and notes CBP began accepting reconciliation entries for refunds on June 29 after requiring importers to have a valid importer-of-record number on file by July 30. Each of those figures describes the pipeline CBP is processing, not any single company’s or household’s own refund, which depends on how much that importer paid in now-invalidated tariffs. The gap between the roughly $110 billion CBO measured through August and CBP’s own $134.7 billion figure for potential and certified refunds also reflects timing: refunds move through review, certification and payment in stages, so the pipeline’s total grows for weeks or months after CBP first calculates how much a given entry is owed before that money is actually transmitted.
Who Actually Collects A Refund
The money moving through this pipeline goes to the importer of record on each shipment, typically a retailer, wholesaler or manufacturer, not to the shopper who eventually bought the finished product. Costco’s own fiscal fourth-quarter earnings release, filed Sept. 24, disclosed a non-recurring $0.15-per-share benefit from these same IEEPA refunds, a concrete example of the money landing on a company’s books rather than as a rebate check to individual customers. Whether a refunded company eventually passes any of that savings on through lower shelf prices is a decision each retailer makes on its own; nothing in CBP’s filing or the refund process itself requires it, and the Tax Foundation’s own tariff tracker still estimated tariffs broadly cost the typical U.S. household around $820 in 2026, a separate figure describing what households pay across all tariffs combined, not what any single refund returns to them. The distinction matters for a retired household reading headlines about an $11.4 billion refund expansion and wondering whether it changes what anything actually costs at checkout; by the filings CBP and the Tax Foundation each keep, it does not, at least not directly or on any schedule either agency sets.
Where The Money Stops, And Where It Doesn’t
None of the billions moving through CBP’s refund process on Oct. 6 reach a retired household’s own property-tax bill or utility account, which are set by local government and utility providers on entirely separate calendars. A homeowner is not a party to CBP’s importer-refund filings and has no claim on the money regardless of how large the pipeline grows. The relief programs that do reach that household’s own bills exist separately, require their own paperwork, and do not open or close based on anything Customs decides about tariff refunds. Oct. 6 will matter to import compliance officers and the finance departments tracking a company’s own IEEPA exposure; it changes nothing about when a county mails a property-tax bill or when a utility company opens its next assistance enrollment window.
A Refund Pipeline That Bypasses The Household Budget
CBP’s Oct. 6 refund expansion moves billions between the government and the importers of record who paid tariffs a court has since invalidated, not into a homeowner’s property-tax or utility account. Those bills stay due on their own local timelines no matter how large the federal refund pipeline grows.
