Product classification
HS code for Semiconductor assembly machine: 8486.40
Machines and apparatus of a kind used solely or principally for the manufacture or repair of masks and reticles, assembling semiconductor devices or electronic integrated circuits, or for lifting, handling, loading or unloading items of heading 8486.
Classification of semiconductor assembly machine under HS 8486.40
Semiconductor assembly machines are classified under HS code 8486.40. Heading 8486 was specifically created to consolidate machines and apparatus used solely or principally for the manufacture of semiconductor boules, wafers, devices, electronic integrated circuits, or flat panel displays. Sub-heading 8486.40 focuses on the assembly stage of the semiconductor manufacturing process. This includes the physical mounting of the die onto a lead frame or substrate and the subsequent electrical connection and encapsulation. The classification is driven by Note 11 to Chapter 84, which mandates that machines meeting the description of heading 8486 must be classified there and nowhere else in the Nomenclature, overriding more general headings for mechanical appliances or electrical machinery.

Codes often confused with 8486.40
Common mistake. Before the creation of heading 8486, these machines were often classified under 8479 (machinery having individual functions) or 8515 (soldering and welding machines). Even today, some components are misclassified under 8515.11 or 8515.19 because of the soldering nature of wire bonding. However, because these machines are used "solely or principally" for semiconductor assembly, 8486.40 takes legal precedence. Testing equipment for semiconductors is also sometimes confused with assembly machines but should be classified under 9030.
Top exporters and importers of HS 848640 (the code used for semiconductor assembly machine), 2025
In 2025, the largest exporter of HS 848640 (the code used for semiconductor assembly machine) in UN Comtrade data was Singapore, with 32% of world exports; the largest importer in UN Comtrade data was China, with 31% 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 848640, not only semiconductor assembly machine.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).

Questions about semiconductor assembly machine
What is the HS code for Semiconductor assembly machine?
The HS code for Semiconductor assembly machine is 848640 (Machines and apparatus of a kind used solely or principally for the manufacture or repair of masks and reticles, assembling semiconductor devices or electronic integrated circuits, or for lifting, handling, loading or unloading items of heading 8486). The specific HS code for machines used in the assembly of semiconductor devices is 8486.40.
How do I classify Semiconductor assembly machine for customs?
Semiconductor assembly machine is classified under HS code 848640 — Machines and apparatus of a kind used solely or principally for the manufacture or repair of masks and reticles, assembling semiconductor devices or electronic integrated circuits, or for lifting, handling, loading or unloading items of heading 8486. This is a 6-digit subheading level code.
Does 8486.40 include machines for making printed circuit boards?
No, machines for the manufacture of printed circuit boards (PCBs) are generally classified under 8486.30 or other specific headings, as 8486.40 is focused on the assembly of the semiconductor devices themselves.
Which countries are the top exporters of semiconductor assembly machine (HS 848640)?
In 2025, the top exporters of HS 848640 (the code used for semiconductor assembly machine) in UN Comtrade data were Singapore ($4.7B, 32% of world exports), Japan ($2.4B) and South Korea ($1.9B). World exports came to about $14.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
