HS Code 8548.00 – Electrical parts of machinery or apparatus; not specified or elsewhere included in this chapter
HS code 8548.00 is the 6-digit subheading for electrical parts of machinery or apparatus, not specified or elsewhere included in this chapter. It is used for custom wiring harnesses, specialized sensor modules, proprietary control boards, unique electrical connectors and custom power distribution units.
What HS 8548.00 covers
HS 854800 serves as a "catch-all" for electrical parts of machinery or apparatus that don't fit into more specific headings within Chapter 85. This code is frequently used for components that are distinctly electrical in nature but lack a dedicated classification, often due to their unique design, specialized function, or composite nature. Trade under this code involves a wide array of items, from custom-fabricated circuit boards for niche industrial machines to proprietary sensor assemblies or unique wiring harnesses. Importers are typically manufacturers of complex machinery, R&D facilities, or specialized repair services seeking specific, non-standard electrical components. Exporters are often custom component manufacturers or suppliers of highly specialized parts. Due to its residual nature, accurate classification requires careful scrutiny to ensure the part isn't more appropriately covered by another, more specific HS code, which can prevent customs delays and incorrect duties.

Codes often confused with 8548.00
Common mistake. This code is a residual category and is often confused with more specific codes like those for switches (8536), resistors (8533), or printed circuits (8534) if the part has a primary function covered by those headings. Careful analysis is needed to ensure the part is truly "not specified or elsewhere included."
Top exporters and importers of HS code 854800, 2025
In 2025, the largest exporter of HS code 854800 in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was China, with 32% 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 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. 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).
