I don't think it's based on CPI. The fluctuations are too frequent for this timescale. They must be plugged into some real-time daily or weekly data for some kind of import prices / domestic prices. Amazon price data maybe? Not sure what else would be avialable that is so high frequency.
This paper examines the short-run impact of the 2025 U.S. tariffs on consumer prices using a unique integration of high-frequency retail pricing data
