HS code for Particle accelerator: 8543.10

Electrical machines and apparatus, particle accelerators.

Classification of particle accelerator under HS 8543.10

Particle accelerators are classified under HS code 8543.10. This classification falls under Chapter 85, which covers electrical machinery and equipment. Heading 8543 is a basket heading for electrical machines and apparatus having individual functions, not specified or included elsewhere in Chapter 85. Particle accelerators are devices that use electromagnetic fields to propel charged particles to very high speeds and contain them in well-defined beams. Because these machines have a distinct function that is not covered by more specific headings (such as motors, generators, or telecommunications equipment), they are placed in 8543. The subheading 8543.10 specifically identifies these complex scientific and industrial instruments. This includes a wide range of devices from small laboratory cyclotrons to massive linear accelerators used in physics research or industrial applications like ion implantation. The classification covers the entire assembly, including the vacuum system, the magnets for beam steering, and the radio-frequency cavities for acceleration. Even if the accelerator is used for medical purposes, such as producing isotopes, it remains under 8543.10 unless it is integrated into a specific medical device. The logic follows GRI 1, as the heading 8543 specifically provides for machines with individual functions, and the subheading 8543.10 is the most specific description for this technology.

Codes often confused with 8543.10

Common mistake. Particle accelerators are often misclassified under 9022.21 or 9022.29 if they are used for medical radiotherapy. However, 9022 is for apparatus based on the use of X-rays or alpha, beta, or gamma radiations. If the machine is primarily an accelerator, 8543.10 takes precedence. It is also sometimes confused with 8486.20 for semiconductor manufacturing equipment.

Top exporters and importers of HS 854310 (the code used for particle accelerator), 2025

In 2025, the largest exporter of HS 854310 (the code used for particle accelerator) 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.

Figures cover everything classified under HS 854310, not only particle accelerator.

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).
