Methodology & data quality

MFN base rates are transcribed from the official USITC general column; the 301 lists, Section 232 layers and global 301 tiers from Federal Register notices — every row traceable (code pages and the radar link each entry to its source). Some rows in the ruleset carry sample/unverified flags — that is our honest boundary: the data suits research, sourcing and price-comparison use; for formal entry rely on USITC/CBP and a licensed customs broker.
