Heading 610990 is the six-digit HSN family; the United States files ten-digit HTS lines beneath it. This crosswalk enumerates all 21 US lines under heading 610990 with their general (MFN) duty rates, spanning 4 distinct rate tiers (2.6%, 5.6%, 16.0%, 32.0%). Every figure is recomputed at build time from the official USITC schedule export.
No. Under heading 610990 the general rate spans 2.6% to 32.0% across 4 tiers, so the six-digit HSN prefix alone is not enough to price an order. Choosing the wrong statistical suffix changes the ad-valorem bill even though the goods look identical; sibling-line dispersion is exactly what this page quantifies.
From the official USITC Harmonized Tariff Schedule export (snapshot 2026-10-19T13:27:57Z, 23,193 records). The displayed ad-valorem rate is the first percentage token found in the general column; Other-rate rows without a percentage are shown verbatim and excluded from the min-max spread statistics.
