Heading 9027 of the Harmonized Tariff Schedule covers instruments and apparatus for physical or chemical analysis (for example, polarimeters, refractometers, spectrometers, gas or smoke analysis apparatus); instruments and apparatus for measuring or checking viscosity…. It divides into 7 six-digit subheadings and 23 eight-digit tariff lines, with 44 ten-digit statistical suffixes below them.

22 of its 23 lines with a percentage rate are duty-free at the general rate (96%) and 1 are dutiable, from duty-free up to 1.2%. The median line pays duty-free.
