Product classification
HS code for Wafer processing parts: 8486.90
Machines and apparatus of heading 8486, parts and accessories.
Classification of wafer processing parts under HS 8486.90
Wafer processing parts are classified under HS code 8486.90 because they are identifiable parts and accessories solely or principally used with the machines and apparatus of heading 8486. Heading 8486 is a specific provision that covers machines used for the manufacture of semiconductor boules or wafers, semiconductor devices, electronic integrated circuits, or flat panel displays. According to Note 9 to Chapter 84 and the General Rules of Interpretation (GRI) 1 and 6, parts that are suitable for use solely or principally with these machines must be classified here rather than in more general headings for parts of machinery. This classification includes components that facilitate the chemical vapor deposition, ion implantation, or epitaxial growth processes essential to semiconductor fabrication. The classification is determined by the functional dedication of the part to the parent machine, ensuring that specialized semiconductor manufacturing equipment components are grouped together for trade monitoring and tariff application.

Codes often confused with 8486.90
Common mistake. These parts are frequently misclassified under heading 8473, which covers parts for automatic data processing machines (computers). However, because these parts are used in the manufacturing process rather than the operation of the computer itself, 8486.90 takes precedence. Another common error is using 8538, which covers parts for electrical switching apparatus, or 8414 for vacuum pump parts if the component is used in a vacuum system. If a part is specifically designed for a machine in 8486, Note 2(b) to Section XVI generally directs it to 8486.90.
Top exporters and importers of HS 848690 (the code used for wafer processing parts), 2025
In 2025, the largest exporter of HS 848690 (the code used for wafer processing parts) in UN Comtrade data was the United States, with 19% of world exports; the largest importer in UN Comtrade data was the Netherlands, with 16% 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 848690, not only wafer processing parts.

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 wafer processing parts
What is the HS code for Wafer processing parts?
The HS code for Wafer processing parts is 848690 (Machines and apparatus of heading 8486; parts and accessories). The primary HS code for parts and accessories of semiconductor wafer processing machines is 8486.90.
How do I classify Wafer processing parts for customs?
Wafer processing parts is classified under HS code 848690 — Machines and apparatus of heading 8486; parts and accessories. This is a 6-digit subheading level code.
Are general-purpose valves used in wafer machines classified here?
No, general-purpose parts like valves, bearings, or gaskets are typically classified in their own respective headings (e.g., 8481 for valves) even if intended for use in wafer processing equipment, per Note 1 to Section XVI.
Which countries are the top exporters of wafer processing parts (HS 848690)?
In 2025, the top exporters of HS 848690 (the code used for wafer processing parts) in UN Comtrade data were the United States ($7.1B, 19% of world exports), Japan ($6.2B) and the Netherlands ($5.1B). World exports came to about $37.7B, 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.
Which countries are the top importers of wafer processing parts (HS 848690)?
In 2025, the top importers of HS 848690 (the code used for wafer processing parts) in UN Comtrade data were the Netherlands ($6.7B, 16% of world imports), Taiwan (about $6.2B) and China ($5.7B).
