Schedule description for this heading: “Having uppers of which over 90 percent of the external surface area (including any accessories or reinforcements such as those mentioned in note 4(a) to this chapter) is rubber or plastics (except footwear having foxing or a foxing-like band applied or molded at the sole and overlapping the upper and except footwear designed to be worn over, or in lieu of, other footwear as a protection against water, oil, grease or chemicals or cold or inclement weather)”.

Rate caliber: first percentage in the general column; Other-rate rows (no percentage, not Free) are excluded from the min–max spread. Source: USITC HTS export, snapshot 2026-10-19T13:27:57Z.
Heading 640299 is the six-digit HSN family; the United States files ten-digit HTS lines beneath it. This crosswalk enumerates all 54 US lines under heading 640299 with their general (MFN) duty rates, spanning 8 distinct rate tiers (3.0%, 6.0%, 8.0%, 12.5%, 20.0%, 24.0%, 37.5%, 48.0%). Every figure is recomputed at build time from the official USITC schedule export.
No. Under heading 640299 the general rate spans 3.0% to 48.0% across 8 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.
