9001

Analysis

Heading 9001 of the Harmonized Tariff Schedule covers optical fibers and optical fiber bundles; optical fiber cables other than those of heading 8544; sheets and plates of polarizing material; lenses (including contact lenses), prisms, mirrors and other optical elements…. It divides into 6 six-digit subheadings and 10 eight-digit tariff lines, with 14 ten-digit statistical suffixes below them.

The spread of 6.7 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.7%, applies to 9001.10.00 (optical fibers, optical fiber bundles and cables).

6 of its 10 lines with a percentage rate are duty-free at the general rate (60%) and 4 are dutiable, from duty-free up to 6.7%. The median line pays duty-free.

The largest subheadings are 9001.90 (other, 5 lines), 9001.10 (unnamed, 1 line), 9001.20 (unnamed, 1 line) and 9001.30 (unnamed, 1 line).
