Heading 7304 covers tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel. It splits into 9 six-digit subheadings and 22 US tariff lines, 22 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.
