THE WHAT? Costco has filed a lawsuit to secure eligibility for tariff refunds should the US Supreme Court overturn President Trump’s global tariff strategy, becoming one of the largest retailers to challenge the administration’s use of emergency economic powers.
THE DETAILS The complaint, filed on 28 November in the US Court of International Trade, argues that Customs and Border Protection’s refusal to extend tariff-determination deadlines could prevent Costco from reclaiming duties if the Supreme Court rules the tariffs unlawful. Dozens of businesses—including Revlon Consumer Products Corp.—have submitted similar filings since late October as the court deliberates on the legality of Trump’s tariff framework, which was questioned by several justices during November hearings.
Retailers have faced persistent cost volatility throughout 2025, particularly across non-food imports. While exemptions and rate adjustments have softened the overall blow, categories such as electronics, apparel, and selected consumer goods have experienced higher landed costs. Costco, like many operators, has adjusted sourcing, accelerated ordering cycles and shifted merchandising to offset tariff impacts.
THE WHY? With a Supreme Court ruling pending, major retailers are seeking legal protection to recover potentially unlawful tariff payments—an issue with downstream implications for retail pricing, supply-chain planning and cost management across multiple categories, including beauty and personal care imports.
