One 6-digit HS subheading (the WCO-international level shared by every member country) → the universal HS6 description plus the matching US (USITC HTS) and UK (HMRC) national lines side by side, with each market's duty rate. The same product, compared across the markets we cover — first 6 digits identical worldwide, national 8/10-digit detail differs.
