HS Code 8543.10 – Electrical machines and apparatus; particle accelerators

HS code 8543.10 is the 6-digit subheading for electrical machines and apparatus, particle accelerators. It is used for linear accelerators (LINACs), cyclotrons, synchrotrons, betatrons and electrostatic accelerators.

What HS 8543.10 covers

This specialized HS code covers particle accelerators, complex electrical machines designed to propel charged particles to very high speeds and energies. These sophisticated devices are not consumer goods but are critical tools in scientific research, medical applications (like radiation therapy and isotope production), and industrial processes (such as materials modification and sterilization). The trade in particle accelerators is highly niche, involving specialized manufacturers and research institutions, universities, and hospitals as primary importers. Countries with advanced scientific research programs and healthcare infrastructure, such as the USA, Germany, Japan, and China, are major importers. Exporters are typically nations with leading-edge engineering and physics capabilities, including the USA, Germany, Switzerland, and Japan. Key aspects of this trade involve custom design, high-precision engineering, safety regulations, and significant installation and maintenance requirements. The market is driven by advancements in physics, medicine, and materials science.

Top exporters and importers of HS code 854310, 2025

In 2025, the largest exporter of HS code 854310 in UN Comtrade data was Belgium, with 24% of world exports; the largest importer in UN Comtrade data was China, with 23% 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).
