President Donald Trump on Tuesday told CNBC that he will gratefully "remember" U.S. companies that do not seek refunds for the tariffs he unilaterally imposed, which the Supreme Court later ruled were illegal.

Trump's comment on "Squawk Box" came a day after U.S. Customs and Border Protection opened a portal for importers to seek more than $160 billion in potential refunds for the so-called IEEPA tariffs.

The president on Tuesday again complained about the 6-3 Supreme Court decision that voided those tariffs. That ruling, he griped, did not include a sentence that said, "You don't have to pay back tariffs that have already been received."

"So, I'm not happy with the Supreme Court, I'll be honest with you," Trump said.
