All seven members - RM, Jimin, V, Suga, Jungkook, Jin and J‑Hope - posted an identical message explaining that none of the tracks from ARIRANG will be put forward for next year's Grammys.
Their joint statement makes clear the move is a direct response to the Recording Academy's new Asian‑specific category, which they say reduces artists to "region or language" rather than judging the music itself.
Translated into English, the social media statement said: "We have decided not to enter the Grammys this year.
"I hope that music can be heard and loved for what it is, rather than being divided by region or language.
Thank you to Army and everyone who is always with us."
Their withdrawal comes as Swim, the group's recent US chart‑topper, had been widely tipped as a major contender for Song of the Year.
But the track's English‑language lyrics would have made it ineligible for the Recording Academy's newly introduced Best Asian Pop Music Performance category, which requires "meaningful use" of an Asian language.
Despite being nominated five times and making history as the first K-pop act to receive Grammy nods, BTS are yet to be awarded by the Recording Academy.
BTS previously recalled how they were "on the brink of mental exhaustion" before performing at the 2022 Grammys.
The septet had members struck down with COVID-19 before their appearance at the MGM Grand Garden Arena in Las Vegas to perform Butter, and had just a single day of rehearsals.
J-Hope told Weverse magazine: "After testing positive for COVID-19, it was only going to be possible to have exactly one day before the performance.
"I think making it to the Grammy Awards stage, under those circumstances, is what put me in the mindset I had for the performance."
As well as J-Hope and Jungkook testing positive for COVID-19, Jin had injured his hand.
He continued: "The other members were on the brink of mental exhaustion at that point, to be honest.
"I knew there was no way I couldn't be there.
"I kept telling myself I have to do this no matter what, went over on the plane, rehearsed on location, and somehow got it all together."
As well as members of the boy band testing positive for the virus, COVID-19 regulations almost saw the performance axed altogether.
Producer Ken Winston revealed: "There were times when we were worried they weren't gonna be able to be here. J-Hope had COVID and was quarantined. And he wasn't allowed to fly until Saturday, the day before the show, Jungkook was in Vegas with COVID, but then unless he got two negative tests, he wasn't allowed to come. It was very tense. We were very nervous."
