HS code for Power converter: 8504.40

Electrical static converters.

Classification of power converter under HS 8504.40

Power converters are classified under HS code 8504.40, which covers "static converters." This category includes a wide range of electrical apparatus that convert electrical energy to change its characteristics, such as voltage, frequency, or waveform. Heading 8504 generally includes electrical transformers, static converters, and inductors. Static converters are distinguished by the fact that they do not use moving parts (like rotary converters) to perform the conversion. Instead, they utilize semiconductor devices like diodes, thyristors, or transistors. This code is essential for international trade as it encompasses everything from small AC/DC adapters for consumer electronics to large-scale industrial inverters used in renewable energy systems. The classification logic relies on the function of the device as a "static" intermediary in the electrical supply chain. Whether the device is stepping down voltage for a laptop or converting DC from solar panels into AC for the grid, the fundamental operation remains a static conversion of electrical energy. These devices are critical for the modern energy transition, enabling the integration of various power sources and loads that operate on different electrical standards.

Codes often confused with 8504.40

Common mistake. Power converters are often misclassified under 8504.31 through 8504.34, which are reserved for liquid-dielectric or other transformers. While converters often contain transformers, the presence of semiconductor circuitry for conversion makes 8504.40 the correct code. Another common error is classifying computer power supplies under 8471.70 (storage units) or 8471.80 (other units of automatic data processing machines). However, according to General Interpretative Rule 1, if a product is specifically described by a heading (like static converters in 8504), that heading takes precedence over more general functional headings. Furthermore, rotary converters are excluded and should be classified under 8501.

Top exporters and importers of HS 850440 (the code used for power converter), 2025

In 2025, the largest exporter of HS 850440 (the code used for power converter) in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was the United States, with 17% 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 850440, not only power converter.

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).

Questions about power converter

What is the HS code for Power converter?

The HS code for Power converter is 850440 (Electrical static converters). The HS code for power converters, specifically static converters, is 8504.40.

How do I classify Power converter for customs?

Power converter is classified under HS code 850440 — Electrical static converters. This is a 6-digit subheading level code.

Are battery chargers included in this HS code?

Yes, battery chargers are considered static converters because they convert AC mains power into DC power suitable for charging batteries, and thus fall under 8504.40.

Which countries are the top exporters of power converter (HS 850440)?

In 2025, the top exporters of HS 850440 (the code used for power converter) in UN Comtrade data were China ($34.5B, 31% of world exports), Germany ($9.3B) and the United States ($6.2B). World exports came to about $109.6B, 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.
