Doesn’t it have to do with the new consumer law regarding the coin batteries?

Heard something about it.

Edit. Found this.

Likely the most far-reaching new requirement is that all consumer products containing coin or button cell batteries must be certified to comply with a formerly voluntary standard, UL 4200A-2023, to be lawfully manufactured or imported after March 19, 2024 (unless they are toys certified to meet ASTM F963).
