HS Code 9017.80 – Mathematical instruments and equipment; n.e.c. in heading no. 9017
HS code 9017.80 is the 6-digit subheading for mathematical instruments and equipment, n.e.c. in heading no. 9017. It is used for planimeters, pantographs, integrators, harmonographs and curvimeters.
What HS 9017.80 covers
This "not elsewhere specified" (n.e.c.) category within heading 9017 captures a diverse array of mathematical instruments and equipment that don't fit into the more specific subheadings like drafting tables, drawing instruments, or micrometers. It serves as a catch-all for various specialized tools used in mathematics, engineering, and technical fields, ensuring that all such instruments are properly classified for international trade. Importers and exporters range from general scientific equipment suppliers to niche manufacturers catering to specific technical applications. The trade in these items is influenced by the evolving needs of education, research, and specialized industries. Key considerations include the specific function of the instrument, its precision, and its application in various technical disciplines. This code highlights the breadth of tools required to support mathematical and technical endeavors globally, from educational settings to advanced research laboratories.

Codes often confused with 9017.80
Common mistake. This code is often confused with 901720 (drawing instruments) or 901730 (micrometers, calipers) if the instrument has a secondary drawing or measuring function, but its primary purpose is not explicitly covered by those. It's also distinct from 903180 (other measuring instruments) which is a broader category for non-optical measuring devices.
Top exporters and importers of HS code 901780, 2025
In 2025, the largest exporter of HS code 901780 in UN Comtrade data was China, with 48% of world exports; the largest importer in UN Comtrade data was the United States, with 18% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
