Costco has joined a fast-growing list of companies suing the Trump administration to ensure that they are eligible for refunds if the Supreme Court of the United States (SCOTUS) strikes down the US president's global tariffs policy

What did Costco's lawyers say?

Costco's lawyers said the suit, filed on 28 November, was a result of the uncertainty regarding the guarantee of refunds for all companies that have been paying additional duties if SCOTUS declares Trump tariffs to be illegal.

The lawsuit, however, has not specified how much the company had to pay because of the additional tariffs imposed by the Trump administration.

The company said that intervention from the court was required at the earliest, after the US Customs and Border Protection denied its request to extend the schedule for finalising tariffs. This could jeopardise the company's chances of seeking full refunds in future, reported Bloomberg.

Dozens of companies have filed lawsuits in the US Court of International Trade since late October, challenging Donald Trump's use of economic emergency powers to impose sweeping global tariffs. Now, Costco, the biggest warehouse club chain in the country, has decided to follow suit.

Costco, one of the biggest companies in the country, has jumped into the ring in a case driven by smaller businesses and Democratic leaning-state officials.

The arguments on Trump's tariffs were heard by the US Supreme Court on 5 November. The case was put on a fast-track schedule by the judges presiding over the same, who, however, have not clarified when they intend to pass judgment in the case. Businesses, meanwhile, have been suing the Trump government to avoid the uncertainty regarding their refund eligibility in case the court ruling goes against the US president.

What has the White House said regarding the tariffs?

Kush Desai, the White House spokesperson, said in a statement, “The economic consequences of the failure to uphold President Trump’s lawful tariffs are enormous, and this suit highlights that fact. The White House looks forward to the Supreme Court’s speedy and proper resolution of this matter.”

Judges sceptical of Trump tariffs

Despite Trump tariffs generating tens of billions of dollars a month, judges are sceptical of their legality. Lower federal courts have already ruled against the Trump tariffs, but have allowed the government to continue enforcing them pending the Supreme Court's judgment.

Some major companies, besides Costco, that have filed lawsuits against the US government include Revlon Consumer Products Corp and Kawasaki Motors Manufacturing Corp.

With the tariffs going through a number of changes in rates after Trump's negotiations with several countries, their overall impact has been more muted than initially expected.

What Costco is doing to mitigate tariff impacts

Costco has said that tariffs are primarily impacting its non-food items, and that it has rerouted some products to markets outside the US, ordered higher quantities of inventory to make their position secure ahead of the new levies, and also purchased goods from a lower number of suppliers with consolidated buying. It has also been changing merchandise altogether whenever items got too expensive.

The company's Chief Financial Officer, Gary Millerchip, had earlier told Bloomberg News, “We’re doing everything we can,” adding, “Whether that’s working with the suppliers to find efficiencies to offset the impact of tariffs, or whether it’s sourcing with them often to different countries.”

Costco has said that it has kept the prices of bananas and pineapples, which are imported from countries in Central and South America, steady, considering their importance to customers. On the other hand, prices of flowers, which are less essential, have increased.
