Analysis
Heading 4503 of the Harmonized Tariff Schedule covers articles of natural cork. It divides into 2 six-digit subheadings and 7 eight-digit tariff lines, with 7 ten-digit statistical suffixes below them.
The spread of 14 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 14%, applies to 4503.90.60 (other: other).
6 of its 7 lines with a percentage rate are duty-free at the general rate (86%) and 1 are dutiable, from duty-free up to 14%. The median line pays duty-free.
The largest subheadings are 4503.10 (corks and stoppers, 4 lines) and 4503.90 (other, 3 lines).
By Census's concordance, most of its statistical lines are made by All Other Miscellaneous Wood Product Manufacturing (321999). Those are the NAICS industries a US producer of these goods would report under.
Its median rate of duty-free sits at the 47th percentile of the headings in chapter 45.
