Heading 9031 covers measuring or checking instruments, appliances and machines, not specified or included elsewhere in this chapter; profile projectors; parts and accessories thereof. It splits into 3 six-digit subheadings and 3 US tariff lines, 3 of which are duty-free under the general rate.
Headings are the four-digit level of the Harmonized System — the layer that is identical across all 160-plus countries that use it. The six-digit subheading is also international; the last two digits of each code here are US-specific and do not carry across to another country's tariff.
