No. Under heading 610310 the general rate spans 0.9% to 28.2% across 6 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.
