Home Depot's $730M tariff refund moved gross margin 25 basis points. That is the whole story.

Home Depot collected $730 million of refunded IEEPA tariffs in a single quarter, arriving mostly as a lump sum near the end of June, and the net effect on year-over-year gross margin was 25 basis points ^[2][6]. The distance between those two numbers is the point: a refund is a cash event, not a cost structure.

The money traces to a February Supreme Court ruling that forced Customs and Border Protection to begin returning duties collected under a law that has since been struck down, according to Fortune, with the proceeds now appearing on the books of Home Depot, Amazon and Walmart ^[1].

Home Depot's arithmetic, as CFO Richard McPhail laid it out on the Q2 call, is unusually legible. Of the $730 million, $685 million related to inventory already sold, so it hit cost of goods sold immediately and produced a 145 basis point gross margin benefit; the remaining $45 million sits in inventory and flows through as that inventory sells ^[3][4][5]. That means about 94 percent of the refund landed in one quarter's COGS ^[19]. Then 60 basis points of unplanned cost inflation cut the benefit to 85, and a 60 basis point drag from acquisition-related mix brought the net year-over-year improvement to 25 ^[6]. Roughly 83 percent of the reported benefit was absorbed before it reached the margin line ^[20].

EVP of merchandising Billy Bastek attributed the inflation to resin, metals, fuel and energy costs that were not in the original 2026 plan, alongside a shifting trade regime: the prior tariff structure expired in July and was replaced by a new Section 301 regime targeting imports tied to forced labor ^[7][8]. Home Depot folded the refund into its reaffirmed outlook and is using it defensively, to absorb cost inflation rather than cut prices ^[9]. The quarter beat expectations on sales and comparable-store growth, but cautious consumers and rising costs kept the recovery uneven ^[10].

The other two large recipients show how little the headline number tells you. Amazon CFO Brian Olsavsky disclosed roughly $600 million in Q2 refunds on the July 30 call, describing it as the significant majority of what Amazon expects overall ^[11]. Paired with a separate $600 million fair value benefit on AWS energy contracts, the two cut operating expenses by about $1.2 billion for the quarter ^[12], which means half of that relief had nothing to do with trade policy ^[21]. Olsavsky said Amazon's total trails peers partly because it "was not the importer of record for the large majority of items sold in our store" ^[13], and the company had stockpiled inventory ahead of the tariffs ^[14]. Where Amazon can trace specific import charges passed to customers, Olsavsky said, it will contact them and issue refunds automatically ^[15].

Walmart CFO David Rainey said in May the company is pursuing refunds that could total about $2.4 billion, and will steer the money to price investment rather than margin while keeping it out of guidance ^[16][17]. He called it a relatively small part of the business, under half a percent of U.S. sales ^[18], which implies a U.S. sales base above roughly $480 billion ^[22].

Three things to follow. Whether the new Section 301 regime reintroduces the import cost that was just refunded ^[8]. Whether Home Depot's unplanned inflation in resin, metals, fuel and energy persists into the back half, since the refund cannot be spent twice ^[7][9]. And how much Walmart actually converts into shelf prices, given it deliberately left the $2.4 billion out of guidance ^[16][17].
